The Right Automotive Fluids For Lafayette Drivers

Posted May 24, 2013 10:55 AM

What grade of oil should I use?

All those automotive fluids can be confusing for Lafayette car owners. Recent years have brought new grades of engine oil, types of transmission fluid, coolant, and brake fluid. The right fluid protects your vehicle and helps it perform at its best. The wrong fluid won’t work as well for Lafayette car owners and could even cause damage.

In addition to new grades of engine oil, many SUVs now leave the factory with synthetic oil. Lafayette car owners should always use the recommended grade and type of oil in their engine.

All coolant, also called antifreeze, used to be green. Now there are several other colors of coolant sold at Guaranteed Transmission and Auto Service in Lafayette. Each type is designed to protect the cooling system components that are particular to your vehicle. The wrong stuff can void your SUV cooling system warranty and could even cause engine damage.

Most passenger vehicles on Lafayette roads today use either DOT 3, DOT 4 or DOT 5 brake fluid. Your SUV power brake system is specifically designed to use ONE of these types – you need the right one. Higher numbers do not necessarily mean a higher, upgraded fluid.

Now, the important thing is knowing that your vehicle requires specific grades and types of fluids and that using the right fluids is good and using the wrong ones is bad. Once you’ve got that down, it’s easy to remember to check with your honest Guaranteed Transmission and Auto Service service advisor or SUV owner’s manual to find out which automotive fluids to use.

Go Straight: Wheel Alignment For Lafayette Automobiles

Posted May 14, 2013 12:55 PM



You may have an alignment problem if your car drifts or pulls to one side, your steering wheel’s off center, you have uneven tire wear or your car doesn’t feel like it handles right as you drive down our local Lafayette Indiana streets.

When all of a vehicle’s wheels are lined up exactly with each other, your wheels are in alignment. Running into potholes, smacking a curb or other objects around Lafayette, Indiana are great ways to knock your car out of alignment. Then one or more of your wheels starts pulling in a slightly different direction and the problems begin.

Driving for an extended time when your car is out of alignment causes your tires to wear unevenly and excessively. Sometimes the tire can be worn so badly that it will fail.

At the very least, you’ll have to replace your tires sooner. You could end up with premature wear to your suspension system, which can be really expensive. The front wheel alignment is adjustable on all vehicles, and the back wheels are also adjustable on some cars.

Now, let’s talk about some alignment basics. Wheels are adjustable for toe, caster and camber. The ideal alignment for your car was designed by its engineers.

So, what is involved in an alignment check at our Lafayette Indiana auto dealership? First, there’s an inspection of the steering and suspension to see if anything is bent or broken. Tire condition will also be evaluated.

From there, the vehicle is put on an alignment rack and we take an initial alignment reading.

If all four wheels are adjustable, they are lined up perfectly parallel with the vehicle’s centerline. If the back wheels aren’t adjustable, the direction they push is determined and the front wheels are aligned to match.

Like most things, your manufacturer has suggested a mileage interval for having your alignment checked. But if you run into a curb, pothole or something else that’s given you a big jolt, pay attention to whether your vehicle is pulling to one side when you drive around the Lafayette area. It’s better to have your alignment checked before waiting to see if there is uneven tire tread wear – by then, the damage is done.

Getting your alignment checked when needed is a great way to extend the life of your tires and suspension parts. It also makes sure that your tire meets the road properly for maximum performance and safety.

Come see us at Guaranteed Transmission and Auto Service for more information about your tire alignment. We look forward to seeing you.

Tire Pressure Monitoring System

Posted May 9, 2013 9:17 AM



We all know that under inflated tires wear out more quickly. Under-inflation is also a major cause of tire failure. More flats, blow outs, skids and longer stopping distances are all results of under-inflated tires.

It's hard to tell when a radial tire is under-inflated. If your manufacturer recommends 35 pounds of pressure, your tire is considered significantly under inflated at 26 pounds. The tire may not look low until it gets below 20 pounds.

Uncle Sam to the rescue! A new federal law requires manufacturers to include a Tire Pressure Monitoring System - or TPMS system - in all vehicles by the 2008 model year.

Some 2006 and 2007 models already have TPMS. The system is a dashboard mounted warning light that goes off if one or more of the tires falls 25 % below the manufacturer's pressure recommendations.

The law covers all passenger cars, SUVs, mini vans and pick up trucks. The system must also indicate if it has a malfunction. This technology has been used by race cars for years. They are able to head off problems from under inflation by closely monitoring tire pressure on the track. It's up to your car's manufacturer to determine which of many TPMS systems available they'll use to comply with the law.

Obviously, all of this doesn't come free. Government studies have estimated the net costs. Of course, the TPMS system itself will cost something. Maintaining the system will have a cost, replacement of worn or broken parts and tire repair cost increases. The net cost is estimated to be between $27 and $100.

The costs are partially offset by savings in fuel and tread wear. There is also a saving in property damage and travel delay. Also, the government predicts fewer fatal accidents. They estimate there will be between $3,000,000 to $9,000,000 for every life saved.

Your safety has always been a concern of your service center. They want you on the road and accident free. They've traditionally provided things like tire rotations, snow tire mounting and flat fixes at a very low cost. They've been able to quickly and cheaply provide the service, and they pass the low cost on to you as an expression of their good will. That's why they're concerned about how you'll perceive the changes that this new law will force.

Every time a tire is changed: taken off to fix a flat, a new tire installed, or a snow tire mounted, the service technician is now going to have to deal with the TPMS system. Sensors will need to be removed and reinstalled. The sensors will have to be re-activated after the change. And, unfortunately, the very act of changing the tire will damage some sensor parts from time to time - it's inevitable and can't be avoided.

Even a simple tire rotation will require that the monitor be reprogrammed to the new location of each tire. When a car battery is disconnected, the TPMS system will need to be reprogrammed. TPMS sensor batteries will need to be changed and failed parts replaced.

And the service centers themselves will need to purchase new scanning equipment to work with the TPMS sensors and to update expensive tire change equipment to better service wheels equipped with the new monitoring systems.

Service technicians will have to be trained on many systems and new tire-changing techniques. All of this adds up to significantly increased cost to the service center to perform what was once a very inexpensive service for you. So when you start so see the cost of tire changes, flat repairs and rotations going up, please keep in mind that it's because of government mandated safety equipment. Your service center just wants to keep you safely on the road - and it's committed to do so at a fair price. The effects of the new law will take some time to sort out, but it will help you avoid the most common vehicle failure, and possibly a catastrophic accident.

Smooth Shifting in Lafayette Indiana: Transmission Service

Posted April 30, 2013 12:54 PM



So you have some exciting plans for the Indiana weekend. You’re going to take some of your Lafayette, Indiana friends out on the boat for some water skiing. Of course, you’ve gotten the boat all ready. And you haven’t forgotten about your tow vehicle. You’ve gassed it up and even vacuumed it out. But you want to make sure that your SUV maintenance is up to date.

Think about it – heavy traffic on the way out of Lafayette. There’s hilly terrain as you get to the lake. Some dirt roads – and its going to be pretty hot in Lafayette this weekend. And all the time you’ll be towing around several thousand extra pounds. That all adds up a lot of severe strain on your engine, brakes and transmission.

Let’s just consider the transmission. It’s going to be working overtime, spending more time in lower gears. The internal transmission temperature is going to be much higher than normal. What’s a fun little blast to the local Indiana lake for you is really severe duty for your transmission.

It’s important to have enough transmission fluid. If it runs low, the transmission will run hotter and won’t have the protection it needs to cope with the added stress of towing. Transmission fluid breaks down and gets dirty over time. Whether you have an automatic or manual transmission, you need to have it serviced at Guaranteed Transmission and Auto Service on schedule to make sure it runs efficiently.

An automatic transmission contains a maze of passages through which the fluid has to pass to keep it shifting smoothly. If you neglect transmission service, the passages can get clogged up and you start to have problems.

Neglect your transmission for too long, and it can fail. You really don’t want to pay for a major transmission repair.

This reminds us of how much of our driving around Lafayette, Indiana is under severe conditions. Towing or hauling a big load is obvious, but there are lots of other things that constitute severe driving conditions. Things like short trips, driving in very hot or very cold weather. Dusty roads and city driving around Lafayette, Indiana add to the strain. Basically, any driving that’s not at highway speeds or under ideal conditions.

While you have your vehicle in, ask for a trip inspection. Your Lafayette, Indiana service technician at Guaranteed Transmission and Auto Service will check your belts and hoses and let you know if your brakes are in good shape.

Now, don’t forget the sunscreen.

Timing Belt Service to Save Big Bucks in Lafayette

Posted April 26, 2013 2:30 PM



Your engine is like a finely choreographed dance. All the parts have to work together. If the timing is off at the ballet, dancers crash into each other and fall down. It the timing is off in your engine, it may not run at all. One of the most intricate dances in your engine, has to do with the combustion cycle.

Your SUV engine has cylinders in which a piston travels up and down. At the top of the cylinders are valves open to bring in the air and fuel. And there are valves that open to let out the exhaust after the fuel has been burned.

Call Guaranteed Transmission and Auto Service at 765-447-6012 for answers about your timing belt, or drop by our Lafayette Indiana service center on 3742 State Road 38 East, 47905

It's critical that the values be timed to open and close at precisely the right time in the combustion cycle, or the engine will run poorly or not at all.

The timing belt is responsible for rotating the shafts that control the valves. It's vital and precision work. Timing belts are made of very tough flexible material. They can last a long time. But they eventually wear out and can break. The consequences can be disastrous.

In some engines, the valves actually protrude far enough into the cylinders that they could come in contact with the piston. If the timing belt breaks, the pistons will smash into the valves. Valves get bend or broken. If the engine is spinning fast enough, the broken parts will shred the cylinder head as well. Repairing this damage can cost several thousand dollars.

It's a sad day when this happens; especially since it usually can be avoided. Manufacturers have issued recommendations for when you should replace your timing belt. For some engines, it's at 60,000 miles. For others it's at 90,000 miles or more. If you're approaching 60,000 miles, or have passed it, make sure you check your owner's manual or with your Lafayette Indiana auto service advisor at Guaranteed Transmission and Auto Service for when the timing belt should be replaced. Don't let this one slip by.

Now some timing belts are visible and can be inspected. Others are hidden under a protective cover and are hard to get to. Some timing belts also drive the water pump. If you have a leaky water pump, the coolant will contaminate the timing belt and could make it fail sooner. So if you have this kind of engine, get it in to Guaranteed Transmission and Auto Service for an inspection right away if you have a coolant leak.

Most people in the Lafayette area with this engine design end up with a new timing belt when they replace the water pump. And when you're having your timing belt replaced on schedule, check with your Lafayette Indiana auto service advisor at Guaranteed Transmission and Auto Service to see if it makes sense to install a new water pump, even if it isn't currently having problems, since most of the labor is already being done any way for the timing belt replacement.

As a heads up; larger engines will often have metal timing chains rather than belts. The chains don't need to be replaced like belts.

We've already told you how very expensive it can be to get your car running again after a timing belt fails. You also need to know that replacing the timing belt is very labor intensive and is one of the most costly maintenance services you will have. So if you will be at the point where your timing belt should be replaced in the next year or so, ask for an estimate from Guaranteed Transmission and Auto Service in Lafayette Indiana so you can begin to prepare for the expense.

We at AutoNetTV are committed to helping you make your driving experience as safe and economical as possible. Guaranteed Transmission and Auto Service, your Lafayette service center, can be a valuable partner. Please take advantage of their knowledge and experience, and check out http://AutoNetTV.com for more great auto tips.

Shocks and Struts For Lafayette Bumps and Bounces

Posted April 18, 2013 9:28 AM



If you're like most of us in Lafayette, you want your car to handle well. That's the job of your suspension system.

There are different types of suspension systems, but they all work on the same basic principles. First, there are the springs, which bear the weight of the car. The most common springs are coil or leaf - although we see air springs and torsion bars more often. The springs do most of the work.

Visit our Lafayette location for an inspection of your suspension.

But if all you had were springs, your vehicle would be bouncing around like a bobble head. That's where the shocks come in. They control the rebound of the springs and smooth out the up and down motions. They also keep the tires on the road, and you in control. Some SUVs use struts. Struts are a combination of shocks and springs, together in a more compact system.

Shocks wear out slowly over time, so it's hard to notice when they get badly worn. One way to tell is to look for an uneven, cupping wear on your tires. If the shock or strut is leaking fluid, it needs to be replaced. If your car feels floaty in turns or if the front end dips a lot when you stop, it is time to get your shocks checked. Your owners' manual will tell you when your shocks should be changed - it's usually between 15,000 and 30,000 miles or 24,000 and 50,000 kilometers .

When you replace a shock, be sure to replace all four. Then your car will have an even suspension and will handle much better. Talk with your service advisor about how you drive. No, not your traffic violations, but how often you carry heavy loads, tow a trailer or drive in rough terrain. If you do a bunch of that, you'll need a heavy duty shock.

Regular shocks use hydraulic fluid and air as their dampening system. Premium quality shocks and struts use compressed nitrogen gas instead of air. Gas shocks don't get air bubbles that affect the performance of regular shocks. If you do a lot of high performance driving, off-roading or just want added comfort and control, think about getting premium gas shocks or struts.

Replacing your struts may take your car out of alignment, so be sure to get an alignment at the same time. So, to smooth out the bumps on the road of life, change your shocks and struts when they need it.

Fuel Saving Tip: Fuel System Cleaning Near Frankfort Indiana

Posted April 9, 2013 9:46 AM



A lot of gas is wasted in the Frankfort area by dirty fuel delivery systems.

Let's start at the tank. The gas tank gathers dirt, rust and sediment over the years. That's why there's a fuel filter to clean the fuel after it leaves the tank. A dirty filter will rob the engine of the clean gas it needs to run efficiently.

Guaranteed Transmission and Auto Service Fuel System Cleaning The fuel intake components get coated with gum and varnish over time. This results in fuel being delivered inefficiently and some of that gunk getting into the engine. A fuel system service at Guaranteed Transmission and Auto Service will leave your intake as clean as a whistle.

The big fuel thief is dirty fuel injectors. They deliver fuel to the engine at a specified pressure and in a particular spray pattern. When they're clogged, the fuel doesn't get atomized the way it's supposed to and doesn't get burned as efficiently.

See your owner's manual or ask your Frankfort service advisor at Guaranteed Transmission and Auto Service when a fuel system cleaning is recommended.

Handling Distractions While Driving Around Lafayette

Posted April 2, 2013 10:59 AM



We've all seen people do crazy things while driving to or from Lafayette. A guy shaving in the rear-view mirror, a woman applying makeup, people talking on their phones, texting or drinking from an enormous coffee mug. All of these are an accident waiting to happen.

The truth is everyone in Lafayette Indiana is distracted when we drive. Traffic, road construction and other things outside the car are beyond our control. But the distractions inside our car are things we can often control.

Here's some things that'll give you more control in your car, and help keep your attention on the roads around Lafayette Indiana.

  • Drivers who are 16 to 20 years old tend to be more distracted by the radio, CD or MP3 player.
  • Drivers who are 20 to 29 are more distracted by passengers in the car, including small children.
  • And those over age 65 tend to be more distracted by objects or events that are outside of the vehicle.

Other factors like fatigue, stress and lack of sleep make it harder to pay attention to driving – no matter what age we are. People are also distracted by thinking about relationships, family issues, money and bills. So what can we do to manage these distractions? Well, the first thing is to eliminate as many as we can.

When you get in your car, make sure you're belted in; that the seats, steering wheel and mirrors are adjusted; and your radio or CD player is ready.

Secure any loose objects in the car that can fall on the floor and interfere with your driving.

If you have a drink, make sure it's spill-proof and put in a cup holder. Pets should also be contained.

If you're riding with kids, make sure they're wearing seat belts or secured in safety seats. You may want to give em some distractions to keep them quiet and sitting in their seats. Don't get involved in their arguments while you're driving. Pull over if you need to find a toy or break up a fight.

If you eat while driving, keep it to simple finger foods that aren't messy.

Learning your car's controls before you drive is another way to improve your safety. Know how to work the radio by touch. The same goes for heating and air conditioning controls.

If you have to use a cell phone, a hands-free system is best. But remember, the biggest cell phone distraction isn't the phone itself – it's the conversation. Keep conversations brief and light, or pull over if you can. Your reaction time is much slower when talking and driving, so allow more space between you and the car ahead of you. Know your local laws – it may be illegal to be on the phone or text in the Lafayette Indiana area.

And if you really think you have to shave, change your clothes or put on make-up while driving – you're wrong. Just start getting ready earlier so you have enough time to finish those things before you drive into Lafayette Indiana.

Remember, driving is probably the most dangerous thing you'll do all day – so don't make it any worse. Use these tips to keep you and your loved ones safer behind the wheel.

Training Received by Technicians In Lafayette Indiana

Posted March 26, 2013 9:56 AM



When your car breaks down in the Lafayette Indiana area, or just needs some routine service, it can make you a little nervous. Because your car’s so important to your life, you need to be back on the road as soon as possible. And, with the problem fixed right the first time.

We’ve been checking into some of the training our Lafayette Indiana technicians receive, and we’re very impressed. It’s amazing how much knowledge and skill goes into diagnosing and repairing a modern car. So it’s not like when your uncle worked on his hot rod over weekend.

Today there are four cylinder engines that make more power than the V-8’s in luxury cars 20 years ago. A new V-6 Toyota Camry could beat Sonny Crocket’s Ferrari in a race to 60 mph.

Our engines are more and more powerful and at the same time their fuel economy keeps inching up. And they’re so reliable. This is all due to engineering. But the advances come at the price of simplicity. Modern cars are so much more complex from a mechanical standpoint that it makes your head spin.

Then there’s the electronics. Some cars in the local Lafayette Indiana area have several networked computers controlling most of the engine functions and many other vehicle functions as well. We take all of this sophistication for granted – but somebody has to fix it when it breaks.

It’s a real challenge for your local Lafayette Indiana technicians to keep up. It requires a high level of commitment on the part of the auto technician and the service center as well. In addition to the training, there’s the financial commitment to purchase the diagnostic and repair tools as well.

So where do Lafayette Indiana technicians go for training? There’re many sources. It’s usually a combination of formal classroom training, training provided in the service center by parts and equipment manufacturers, on-line courses and home study courses. There are many independent certifications available all the way up to Master Technician.

And AutoNetTV produces monthly training for service centers called The Pro Channel. If you were to watch the Pro Channel segment on re-flashing the engine control computer, you’d be amazed at how much is involved: special software, hardware interfaces and a tremendous amount of knowledge and skill.

Service centers in Lafayette Indiana have a lot of other resources available as well. No one can know everything, so service centers like Guaranteed Transmission and Auto Service subscribe to data services, technical libraries and even on-line communities that can help them with they run into a difficult problem.

It’s like those medical diagnosis shows on TV. Here are the symptoms – what’s the diagnosis and treatment. Diagnosis is every bit as much an art as a science. As consumers we want everything to be simple, straight forward and cheap – and sometimes it just isn’t.

So, be more relaxed next time you take your car in. You really should trust your service advisor at Guaranteed Transmission and Auto Service. You’re in good hands. The more you know, the more comfortable you can be with your automotive service decisions. Visit AutoNetTV.com to see more great auto tips videos about many service topics.

Saving Lives In Lafayette With Tire Pressure

Posted March 19, 2013 12:36 PM



All new passenger vehicles on our Lafayette Indiana roads now have tire pressure monitoring systemsTPMS for short. They are designed to alert you if your tires are under inflated. Since they are fairly new, a lot of people have questions about TPMS.

First off, the most important thing is that you still need to check your tire pressure every week – or at least every time you gas up. The TPMS system alert comes in when your tire is twenty percent below the factory recommendation. So if the recommended pressure is thirty five pounds per square inch, the TPMS warning won't come on until the pressure is at twenty eight pounds. That's significantly under-inflated. Enough to raise safety concerns.

The worst is tire failure. A severely under inflated tire can overheat and fail. Also, handling degrades to the point that you may not be able to steer out of trouble. Also under-inflated tires wear out faster and they waste fuel. So it's costly to not stay on top of proper inflation.

What's the practical value of the TPMS system? Well, it's twofold. First, it can alert you when your tire is losing pressure due to a puncture or a bent rim. That's an important warning that you might not have gotten until next time you gassed up.

The second is that we all occasionally forget to check our tire pressure. So it's a failsafe system to let you know there's a problem brewing.

Other things can cause your TPMS system to go off. The system also monitors itself. The sensors that are mounted in the wheels have little batteries that send a signal to the monitor. The batteries go dead over time and the TPMS system will let you know. And the sensors could break. Also road salt from our Lafayette Indiana roads can ruin them.

There's also a hassle factor that your Lafayette Indiana tire center has to contend with. For example, when you have your tires rotated in Lafayette, the TPMS system has to be re-calibrated so that it knows which tire is on which corner of the car. Same is true for when you have new tires or winter tires installed. Flat repairs, as well.

That takes extra time. And it requires the right equipment and training. Special – and expensive – tire change machines need to be used with some sensors. It's all complicated by the fact that there are a number of different TPMS systems in use so the tire professionals at Guaranteed Transmission and Auto Service need equipment and training for each kind. Tire centers have had to raise the price of some of these basic services to offset their increased costs.

Also if you add custom wheels on your SUV, you need to put in new TPMS sensors if your originals won't work on the new rims. If you don't your TPMS light will be on constantly and you won't have the benefit of the warning system.

All in all, the mandated TPMS systems will save lives, so they're worth the added hassle and expense.
