The Welch Automotive Guide To Servicing Your Differential

Differential? What’s that? And what’s it for? I’ve been told by my tech that I need to get it serviced, but is that on the level?

Do these questions sound familiar? They’re not uncommon for Franklin drivers. A lot of us in Franklin don’t know what a differential is or what it’s for. Every vehicle has a differential, and, yes, it does need to be serviced. In fact, it’s more vital to the operation of your truck than the air conditioner or windshield wipers.

A differential allows your truck tires to move at different speeds. This happens more than you think. The best example is when a vehicle is turning. The inside wheel travels a much shorter distance than the outside wheel during a turn. This means the outside wheel has to move faster than the inside wheel. Without a differential, your tires would hop and skip while turning. They would also lose traction in sand or snow.

The location of your differential depends on what kind of vehicle you drive. On a rear-wheel drive vehicle, the differential is located in the back. For a front-wheel drive vehicle, it is located on the front, but it is usually called a transaxle. Four-wheel drive vehicles have three differentials: one on the front, one in the back, and one in the middle. This center differential compensates for differences in speed between the front and rear wheels.

Your differential contains strong gears that need to be protected from dirt, debris, water and other contaminants. A differential is sometimes referred to as a “gear box.” The work of these gears is to transfer power from the truck drive train to the wheels.

Your differential needs fluid to lubricate and cool the gears. This fluid, even though enclosed in the “gear box,” can get dirty because the gears grind down over time, releasing tiny bits of themselves into the fluid. Also, the additives in the differential fluid break down and need to be replaced. That’s why vital preventive maintenance for your truck needs to include servicing the differential.

Your owner’s manual can give you recommendations on how often to service your differential. But you should also consult with your honest Welch Automotive tech. Welch Automotive can give you some good auto advice on whether your vehicle needs to be serviced more frequently. For example, if you drive in hot or cold Franklin weather conditions, your differential will need to have its fluid changed more often.

Severe conditions will also affect your car care routine, and your differential. Check your owner’s manual for a definition of “severe service” conditions that affect your vehicle. Examples may include driving with frequent stops and starts, a lot of short trips around Franklin, hot or cold North Carolina weather conditions, and towing.

Off-roading is particularly hard on a vehicle’s differential. If you are an off-roader, especially if you cross North Carolina streams or waterways, it is important that you service your differential more frequently than the recommendations suggest.

Properly servicing your differential will extend its life and keep you out of Franklin auto repair shops. A smooth ride for Franklin motorists is the result of proper preparation and smart choices.

Fuel Saving Tip: Car Weight And Your North Carolina Driving

Weight is the enemy of fuel economy. Everyone from here to Otto knows this makes sense.

Some of us in the Otto area carry a bunch of unnecessary weight, and I’m not talkin’ what you see in the mirror.

truck Weight Guys; sports equipment and tools. Ladies; well, just take a look around the passenger compartment and trunk. I think my car has about forty-five pounds of French fries on the floor.

All that extra weight wastes gas as you drive between here and Otto, and everywhere else.

Lose the junk and save some money.

…And you really only need one of those spare tires.

It Is Time To Check Your Intervals

Part of the engineering that goes into designing a vehicle is testing the components to ensure that they meet durability and safety standards. Because of this, manufacturers have a good idea as to how long the parts in your vehicle will last under normal driving conditions. For this reason, they give us guidelines to follow regarding how often to inspect the various parts and systems on our trucks.

Vehicular components are required to meet certain standards. The government mandates some of these standards. Others are set by the auto industry. Recommended car maintenance schedules are designed to help Franklin car owners maintain these standards. Disregarding routine maintenance or procrastinating preventive maintenance will result in lowered performance and reduced safety for a vehicle.

Maintenance schedules are designed to ensure three areas of important automotive performance for Franklin drivers: protection of the vehicle itself, fuel economy, and safety.

Protection

Your vehicle’s components need protection from dirt, road damage, rust, corrosion and fuel and combustion by products. Protective components include filters and fluids.

Most of the fluids in your truck are there to keep the vehicle running smoothly and to protect the vehicle from corrosion, damage or harmful contaminants. These fluids need to be changed regularly in order to continue protecting your truck.

For example, motor oil lubricates your engine, when keeps it running well, but it also contains detergents and other additives that clean your engine and protect it from corrosion. Your vehicle’s engine was engineered for best performance with a specific weight and type of motor oil. Franklin drivers should always be careful to use the right motor oil for their engine.

Over time, the critical additives in motor oil are depleted, and the oil becomes contaminated by dirt, water and waste gases from combustion. So in order to keep your engine clean and to continue to protect it from corrosion, the oil has to be changed periodically.

Efficiency

Over time, your vehicle’s systems will get dirty and parts will wear down. Cleaning dirty systems and replacing worn parts will improve the efficiency of your vehicle, which is usually measured in terms of fuel economy and power output.

For example, your fuel system components gradually get clogged up with gum and varnish from gasoline. This restricts fuel flow, which lowers your engine’s efficiency. Gas mileage drops as a result. Cleaning your fuel system will restore fuel efficiency and improve gas mileage.

Safety

Some of your truck’s systems must be maintained for safety reasons. Your brakes are a prime example of this. Brake pads and brake fluid need to be replaced in order to ensure good braking power. Poorly maintained brakes lead to accidents for Franklin auto owners.

Your owner’s manual is your first resource when it comes to knowing when and how to maintain your truck. Of course, you can consult with a your Welch Automotive service advisor. He can give you good auto advice on how to adjust your service schedule to account for climate, local road conditions and your driving distances.

Beyond routine maintenance, your vehicle also requires regular inspections. These inspections are usually recommended at specific mileage intervals, like fifteen or twenty thousand miles. The interval is based on the known life expectancy for particular components in your truck. Regular inspections will identify vehicular components that need to be repaired or replaced before damage is done to the vehicle or safety is compromised. They are also designed to safeguard the efficiency and performance of your vehicle.

The multi-point inspection that comes with a full-service oil change does not cover all of the regular inspections your vehicle needs for peak performance and safety. Check with the automotive professionals at Welch Automotive in Franklin to find out what additional inspections your vehicle needs and how often. Good car care requires regular and consistent maintenance. But good maintenance pays for itself in better fuel economy and fewer pricey repairs. It may even save your life.

Franklin Exhaust And Emissions Service

Many Franklin motorists don’t realize that there is more to exhaust system maintanance than just tailpipes and mufflers. And if you can see smoke, or if it’s too loud. Exhaust service at a full-service automotive center like Welch Automotive is really a lot more comprehensive these days.

For example, in the U.S., the federal government required catalytic converters for all cars in Franklin in 1976 and on-board emission control computers in 1990. North Carolina and federal emissions requirements have forced vehicle manufacturers to come up with much more sophisticated ways to comply with environmental laws. This also goes for cars sold in Canada.

So, exhaust service has really become exhaust and emissions service. High-tech computer-controlled emissions devices are now necessary. And because it’s so sophisticated, car makers recommend having your emission system checked out by a qualified technician, like the ones we have at Welch Automotive, regularly to make sure everything’s working right – which is usually every six months or 6,000 miles.

If your ‘check engine light’ comes on while you are driving around the Franklin area, especially if it’s flashing, then you need to bring your car into Welch Automotive ASAP. Chances are it’s an emission related problem. Signs of exhaust or emissions trouble include difficulty starting, engine noise or smoke.

So let’s do a quick rundown of the exhaust system for Franklin car owners. First up, the exhaust manifold. That’s the part that attaches to the engine and collects the exhaust from the cylinders and directs it into the exhaust pipe.

The exhaust gaskets help seal the connection with the manifold and other joints along the way. Now, if the manifold is cracked or loose, or a gasket is leaking, then detrimental gases could escape into the cabin, where you ride. Carbon monoxide can be deadly, so it’s important that your exhaust system doesn’t leak.

The exhaust pipes connect the various important components. They can rust or be damaged by a rock, so they need to be inspected periodically.

Next comes the catalytic converter. This part actually looks like a muffler. It changes toxic chemicals into harmless carbon dioxide and water. The catalytic converter doesn’t require any maintenance itself for Franklin car owners, but eventually it wears out. If yours has stopped working, you probably won’t discover it until your car fails its North Carolina emissions inspection.

Next, the muffler. The critical job of this aptly-named part is to muffle engine noises. Mufflers work by either absorbing or baffling sound. Many Franklin auto owners don’t know that you can actually customize your car’s sound with different mufflers – which is pretty cool because in addition to changing the look of your ride, you can also customize its sound!

Rusted or road-damaged mufflers can actually leak and they need to be replaced right away. The exhaust system is attached to the car by a series of hangers and clamps that hold the system in place. And when these hangers come loose or break then hot exhaust components can touch and melt wires, hoses and lines. Just think of how harmful a hot curling iron can be – but worse. It’s not good to have that waving around. Talk to your honest Welch Automotive service specialist.

And finally, we end at the tailpipe. Appropriate name. This is the final outlet for the exhaust. And one other component is the oxygen sensor. It monitors the oxygen content of the exhaust so the engine-control computer can adjust the critical fuel-to-air mix to keep the car running right.

We hope this hasn’t been too ‘exhausting’ of a discussion. Remember that a properly functioning exhaust system is vital for Franklin auto owners’ health and safety. Talk with your honest service advisor at Welch Automotive in Franklin if you think you might need a diagnostic examination of your exhaust system. A quick look can sure save a lot of pain down the road.

Straight And True In Franklin: Wheel Alignment

Most Franklin folks worry about running out of gas or having a breakdown on the side of the road. That is why we practice preventive maintenance on our vehicles — that and to keep our repair bills down. But one important part of preventive maintenance that may get overlooked by Franklin car owners is a periodic alignment inspection.

Poor alignment causes tires to wear rapidly, unevenly or both. This means they will have to be replaced early, and new tires are more pricey than an alignment check in Franklin. Bad alignment can also cause damage to suspension and steering systems, which can be expensive to repair in Franklin.

Tire wear on misaligned wheels can also lead to blowouts, which are dangerous, can lead to serious accidents, and can seriously damage your truck. Also, poor alignment itself can be the cause of an accident, since the truck may not steer properly.

One or more wheels on your truck can be knocked out of alignment by running over a curb or a pothole on a bumpy Franklin street. An accident, even a minor one, that involves a wheel on your car can lead to misalignment. The small bumps and bangs of everyday Otto driving can also gradually put your wheels out of alignment.

If you have had wheel damage to your truck, or if you suspect that your wheels are out of alignment, you should get your alignment checked NOW. Any Welch Automotive technician will give you that piece of auto advice. But good car care suggests that you also get your alignment inspected on a regular basis. At Welch Automotive in Franklin, we can take care of that for you.

Your owner’s manual or Welch Automotive technician can give you a suggestion on how often your alignment should be checked. If it doesn’t, then once a year is a good rule of thumb. However, if you drive a lot and especially if you drive on rough surfaces a lot, then you may want to consider a diagnostic examination more often. Ask your honest service professional for a recommendation.

If your truck is out of alignment, one or more of the wheels is not tracking correctly and will “pull” against the others. Thus, one sign of poor alignment is that your truck pulls to one side when you drive around Franklin. Also, if you are driving a straight path and your steering wheel is off-center, that usually indicates an alignment problem.

Franklin motorists should also check the wear on their tires. If they seem to be wearing out too quickly, or if you notice that a tire is wearing on one side more than the other, you should get your alignment checked.

When you get an automotive analysis, your vehicle will be put on a rack and all the parts of the steering and suspension systems will be inspected for wear or damage. The alignment of the tires will be charted and compared to the original factory settings. If no repairs are needed on the steering or suspension systems, the wheels will then be adjusted to bring them back into alignment.

This may seem like a lot of bother for Sylva auto owners, but it’s a lot less trouble than a blowout or an accident. The old adage is good auto advice for all Franklin residents: an ounce of prevention is worth a pound of cure.

So keep on driving, and keep all four tires on the road.

Smart Franklin Drivers Protect Against Overheating

Engines get hot when they run. This heat can build up and damage vital engine parts, so engines need a cooling system to keep them running. Cooling system failure is the most common mechanical failure in vehicles. This is unfortunate, because these failures are usually easy for Franklin drivers to prevent.

The radiator is the best-known and most recognizable part of the cooling system. Hoses filled with coolant (also known as antifreeze) connect the radiator to the engine. The coolant draws heat from the engine, and then flows to the radiator. Air passing through cooling fins on the radiator cools the coolant. The coolant then cycles back into the engine to start the process over again.

The most critical component of the cooling system, however, is the coolant itself. A mixture of water and coolant/antifreeze helps keep it both from freezing and from boiling away. Either can result in serious engine damage.

Different engines require different types of coolant/antifreeze. The owner’s manual will list what kind a vehicle requires. Using the wrong type or mixing different types of may void the warranty on the cooling system and may damage it as well.

Insufficient coolant can lead to engine failure. Coolant levels need to be checked regularly and topped off as necessary. If coolant levels drop quickly or consistently, the cooling system should be inspected for leaks. Coolant/antifreeze contains additives that protect the radiator and other coolant components from rust, scale and corrosion. Over time, these additives are depleted, so it is necessary for Franklin drivers to replace coolant at specified intervals. Changing coolant should be part of routine preventive maintenance for any vehicle.

This service is often ignored, though, since old coolant still cools the engine. Vehicle owners don’t realize there is a problem until the system fails. They are left with major repairs and possibly a damaged engine, which could have been prevented with a cooling system service at Welch Automotive in Franklin.

If your truck sends a warning message to check its coolant or if the temperature gauge is reading in the red or hot zone, then the cooling system needs an automotive analysis. This service is important and should not be put off since the potential for damage is high.

In an emergency situation, water or antifreeze can be added to your truck so that it can be driven to a service center for proper car care. For this reason, owner’s manual contains instructions for how to top off insufficient coolant – allow 45 minutes for the engine to cool before attempting to add coolant or water. However, the fluid should be added to the coolant overflow bottle, not to the radiator itself. Removing the radiator pressure cap can result in severe burns.

Topping off in an emergency, however, does not fix the problem. The vehicle should immediately be taken to your Franklin service center or Welch Automotive where they can inspect the cooling system, repair any leaks, and clean it if necessary. They can identify what caused the emergency situation in the first place and ensure it doesn’t happen again.

Regular maintenance of a vehicle’s cooling system is just good auto advice for Franklin car owners. Cooling system service is relatively inexpensive and doesn’t take long at Welch Automotive. Lack of it, however, can put a vehicle in the scrap heap.

Treat Your Vehicle to Good Tires at Welch Automotive

When we shop for shoes, most of us know that we can get two pairs of cheap shoes or one good pair for about the same price. And since the two cheap pairs wear out in about the same time as the good pair, there really is no difference in cost. If you like having a closet full of shoes to match your moods and outfits, then cheap shoes can be what you want. But if you spend a lot of time on your feet, you probably know that cheap shoes can come with an added cost of sore feet and other foot ailments. When you add in the benefits of comfort and protection, the more expensive shoes are actually the better value.

Buying tires at Welch Automotive in Franklin is a lot like buying shoes, except that Franklin motorists’ vehicles don’t have changeable apparel and don’t need a closet full of tires to match. Vehicles spend a lot of time on their tires—all the time, in fact—so they need tires that can stand up to the job. Tires are work shoes: they have to deal with a lot of North Carolina road conditions, all while carrying the weight of a vehicle and its passengers.

Bad tires, like cheap shoes, can also be a safety concern for Franklin area drivers. Tires need good traction, and they need to be strong enough to handle the loads they carry. Vehicles that carry heavy loads or tow trailers around Franklin need tires with a high load rating, in the same way that you are better off on a rough North Carolina mountain trail with sturdy hiking boots rather than flip-flops.

The best tires on the market are called Tier 1 tires. These are high-quality tires engineered to stand up to a lot of wear while maintaining good traction. They are also the most expensive tires on the Franklin area tire market, although prices don’t vary much from brand to brand.

Tire chain stores in Franklin often carry tires with their own brand name. These are private label tires. They are less expensive than Tier 1 tires, but are still a quality product. In fact, many private label tires sold in Franklin are manufactured by the same companies that make Tier 1 tires. Don’t hesitate to ask your Welch Automotive tire professional who makes their private brand.

The cheapest tires on the North Carolina tire market are Tier 3 tires. Most of these tires are imported from Asia or South America, and they just don’t have the same standard of engineering behind them that the higher-priced tires have. When it comes to Tier 3 tires, Franklin folks get what they pay for.

At Welch Automotive, we sometimes express tire quality in terms of the warranty. In other words, we call a tire a “40-thousand-mile tire,” or a “60-thousand mile tire.” This refers to the number of miles a tire will be under warranty. Tires with a higher mileage warranty are made with higher quality rubber compounds and have more tread. As you might expect, they also cost more than tires with low mileage warranties.

Cheap tires often have no warranty at all. However, if you find yourself in a position where you need new tires and you’re really strapped for cash, purchasing Tier 3 tires is better than waiting until you can afford Tier 1. It’s always better for Franklin drivers to drive on new tires, even cheap ones, than driving on tires that are worn past their safety limits.

That said, if you’re driving on Tier 3 tires, it’s a good idea to budget and plan to buy higher-quality tires the next go-around. Two sets of cheap tires may wear out in the same time as one set of quality tires, but the quality tires actually cost less than two sets of cheap tires. That’s the great fallacy of cheap tires. In the long run, they actually cost more than good tires, and come with significantly reduced performance and durability to boot. Not exactly the best value for Franklin auto owners.

So, some good auto advice for Franklin auto owners would be to always buy as much tire as you can afford. That way you’ll get the most durability and performance and the most mileage out of every tire. Plus, with a better tire, there’s some peace of mind that comes with knowing you won’t have to purchase tires as often.

Good car care requires checking your tires occasionally for tread wear and road damage. Practicing this preventive maintenance can help you avoid flats and blowouts.

Keep Your Tires Well Rounded in Franklin: Tire Rotation and Wheel Balancing at Welch Automotive

Taking care of our tires is an essential part of car care for Franklin drivers. We know they have to be replaced when they wear out, but tires also require some important preventive maintenance. This maintenance will improve gas mileage and extend the life of the tires, so it’s well worth the effort and expense for Franklin motorists to get it done. Tire maintenance includes keeping tires properly inflated, rotating tires and balancing wheels.

The recommended tire pressure for a vehicle’s tires is printed on a sticker on the inside of the driver’s side doorjamb. A lot of engineering goes into calculating the correct pressure, so it’s an essential number for Franklin car owners to know. Not following this recommendation can throw off the suspension system and can lead to pricey tire damage. Underinflated tires wear out more quickly than properly inflated tires. Vehicles also get better traction, handling and fuel economy on properly inflated tires. Check your tire pressure at least once a week and add air if necessary.

Don’t be tempted to add a bit of extra air to your tires when you fill them. Overinflated tires will cause the center tread to wear unevenly because of improper contact with the road. It will also impair the handling performance of your vehicle.

Rotating tires allows all four tires on a vehicle to wear evenly. Front tires get more wear than rear tires because they do most of the work on turns. Tire rotation allows all of the tires to spend time on the front of the car so they all experience the extra wear.

For most vehicles, tire rotation is simply a matter of moving the front tires to the rear and vice versa. Some vehicles, however, recommend a cross-rotational pattern. Other vehicles use asymmetrical tires, which means the right tires have to stay on the right side of the car and the left tires on the left. Some vehicles use differently sized wheels on the front and back of the car and should not have their tires rotated.

What kind of rotation do you need? Check your owner’s manual or talk to your honest Welch Automotive technician. Your owner’s manual will have information about how to rotate your vehicle’s tires as well as letting you know how often you should get it done. For most vehicles, that’s usually every 5,000 miles. Your honest Welch Automotive service professional can also offer auto advice about tire rotation. A quick tire inspection can also indicate whether or not your tires are due to be rotated.

When it comes to tire maintenance for Franklin motorists, wheel balancing is usually what we know least about. Balancing a wheel is necessary to keep it in constant contact with the road. If a tire is not balanced properly, it actually hops along the roadway. You can feel this hopping as a vibration in your steering wheel if the unbalanced tire is a front tire. You’ll feel the vibration through your seat if a rear tire is unbalance. Properly balancing your tires is essential and will extend their life span, improve handling and improve the safety of your vehicle. When you replace your tires, the new tires need to be balanced.

Never use different sized tires on the same axle of a vehicle. In other words, your front tires need to be the same size and your rear tires need to be the same size. Mixing sizes can lead to some serious handling problems for Franklin car owners.

If you have an all-wheel drive or four-wheel drive vehicle all four tires need to be the same size. If your tires are wearing out, you can sometimes make a new tire purchase fit within your budget by only buying two tires at a time. When you do this, the new tires should be installed on the rear of the vehicle. Rear tires are more in need of the traction than your front tires to avoid spinning out on slippery surfaces. If you drive a vehicle around Franklin, you need tires, so Franklin drivers need to know how to care for them. The safety of your truck can depend on the condition of your tires.

Using Proper Fluids In Your truck Or Other Vehicle

Today Welch Automotive is talking about the proper fluids for your vehicle. It’s become more complicated with changes in automotive design and manufacturing. It’s not that people in North Carolina are confused as much as they don’t realize how much things have changed in recent years.

If you have questions about the fluids in your vehicle, please don’t hesitate to stop by Welch Automotive. You can find us on 1108 Depot St. in Franklin, North Carolina 28734.
Just give us a call at 828.524.3117

Let’s take engine oil. Twenty or thirty years ago, there were just a handful of different weights of oil. The weight of an oil is a scientific measure of its properties, particularly its viscosity or thickness.

It was common in those days to use a lighter weight oil in the winter when it’s cold outside. That way the oil would be able to splash around inside the engine and protect the parts before it was fully warmed up. And a heavier weight oil would be used in the summer. The thicker oil wouldn’t thin out too much in the summer heat and vaporize in the engine.

Modern valve trains have become very complicated with more moving parts and small passages than ever before. The valve train is in the top of the engine, so when the car has been turned off for a while, the oil tends to run down to lower areas and the valve train parts are vulnerable at start-up, before the oil starts circulating.

So new weights of oil have been introduced to meet the engineering specifications of these newer engines.

Manufacturers are recommending specific weights of oil. The recommendation is often printed on the oil fill cap. It’s certainly in the owner’s manual. Of course, your Franklin North Carolina auto service center can look it up for you.

It’s more important than ever to have the correct weight of oil. The wrong weight could actually harm the engine.

Other fluids are also becoming more sophisticated. In the last few years new types of transmission, power brake fluid and coolant have all been introduced for some of the same reasons as for engine oil.

In addition, vehicle manufacturers are now using a wider variety of materials in these systems. Looking at the cooling system as an example, it used to be that the parts were all made out of steel or iron and the hoses were rubber. Now, some parts are plastic, aluminum or other materials.

So the anti-corrosion additives contained in the coolant, or anti-freeze, need to be different in order to protect the different materials used to make the cooling system. If you use the wrong coolant that wasn’t formulated to protect your plastic cooling system parts, they could become corroded and fail. And if you’re using the wrong coolant, your cooling system won’t be covered under warrantee. So it’s important to use the right coolant and to not mix different types.

Your owner’s manual or your Franklin North Carolina service advisor at Welch Automotive can make sure you’re using the right type. You may have heard of universal coolant. Universal, or global, coolant can be added to other types without harmful reactions. That’s OK for an emergency top off, but following your manufacturer’s recommendation for your truck or other auto type is always a safe bet.

In the area of brake fluid, there are a couple of new formulations. It’s important to remember that the new ones aren’t better than the old ones. They’re just different formulations for different vehicles. So if your vehicle calls for DOT 3, using DOT 4 or DOT 5 is not an upgrade. Use the recommended formula.

There are fluid formulations for vehicles with higher mileage. These are special engine oil, transmission fluid, and so on that contain additives to condition and restore seals and gaskets in older engines.

They’re fine to use as long as they’re a variant of the proper fluid. In other words you can use a high mileage engine oil as long as it’s also the correct weight recommended by the manufacturer. Same goes for transmission fluid; as long as it’s the right type for your transmission.

Watching Your Check Engine Light

Did you know that most of the cars driving around Franklin, North Carolina carry more computer power than the Apollo 121 Lunar Module that landed on the moon in 1969?

New cars sold in the Franklin area have as many as twelve networked computers and over five miles (eight kilometers) of wiring. In fact, for the last decade or so, auto computers have been controlling about 85 percent of your vehicle’s functions.

Cars have sensors for manifold air temperature, coolant temperature, manifold air pressure, airflow, throttle position, vehicle speed and oxygen content. All of this electronic wizardry is pretty complicated. So how do Franklin motorists know when there is a problem?

It’s simple; the Check Engine light comes on. The computer monitors all the sensors and uses that information to decide what to adjust such as the fuel mix, spark timing and idle speed. In addition, the computer monitors its own circuits. When it finds a fault, it turns on the Check Engine light and stores a trouble code in the computer.

It can be pretty disturbing for Franklin car owners when the Check Engine light comes on. We wonder just how urgent it is. Generally speaking, it is not critical like a temperature or oil pressure light. When you get one of those it means STOP NOW! When the Check Engine light shows up, you should come in to Welch Automotive in Franklin to find out what the matter is as soon as possible.

Since 1996, there has been a strong emissions control component to the Check Engine diagnostic. But if your Check Engine light flashes on and off, you know that it is more urgent and you need to get it checked immediately to prevent damage. You should slow down and avoid towing or heavy loads until you can get it checked out.

Your honest Welch Automotive technician has special diagnostic equipment that will retrieve the trouble code from the computer and help him determine what is wrong. From there, we can fix it and get you back on the road.

Stop by if you’re check engine light is on.
