Differential Service

Pro Muffler & Brake Shop Inc Tech Question:
What is a differential and why do Benton Harbor drivers need to have it serviced? Watch this short video to help explain the process.

Pro Muffler & Brake Shop Inc Tech Answer:

First of all – your vehicle does have a differential. If it’s a rear wheel drive, your differential is on the back. If it’s front wheel drive, your differential is built into your transaxle (transmission). Benton Harbor drivers with all wheel drive or four wheel drive will have differentials front and rear and maybe one in between.When you are steering through a turn at an intersection in Benton Harbor, the wheels on the outside of the vehicle have to spin faster than the inside wheels because they have to travel a slightly longer distant through the curve. The differential compensates for these speed differences between the wheels.

Because it is part of the equipment that transfers engine power to the wheels, the differential is working pretty hard. Differential fluid – a special heavy-duty oil – cools, lubricates and protects the differential. It needs to be replaced on a schedule to remove metal shavings and other contaminants. Note: if you have a front wheel drive vehicle, replacing your transmission fluid takes care of your differential service needs.

Differentials have become increasingly sophisticated for Benton Harbor drivers. Rather than the simple mechanical devices of yesteryear, they are more complicated and may actually be part of the computer controlled vehicle stability system. This means they are more so it pays for Benton Harbor drivers to have them serviced on schedule at Pro Muffler & Brake Shop in Benton Harbor to avoid premature wear.

Is it time to check your fuel pump?

Pro Muffler Anti-Lock Brakes
Pro Muffler & Brake Shop Inc Tech Question:
Is it time to check your fuel pump?

Pro Muffler & Brake Shop Inc Tech Answer:

Your fuel pump sends fuel from the fuel tank to the engine. Fuel pumps just wear out over time: it might be the electric motor, a sensor, a valve, or a relay or some other electrical component. Whatever the exact cause for the fuel pump failure may be, the solution to getting you back on the Benton Harbor road is to replace the pump assembly. When one component has failed, another one is probably just around the corner so it makes sense to replace everything at once and save the future labor costs.

The fuel pump is inside the fuel tank on most vehicles, and for many cars, trucks, and SUVs, the fuel tank must be removed to replace the fuel pump. As you can imagine, that is pretty labor intensive: removing heat shields, retaining straps, all of the EVAP lines, fuel lines, and electrical connections. And of course, there is properly and safely handling the fuel that must be drained from the tank.

Some vehicles have an external fuel filter that should be replaced at the same time. The fuel tank may need to be replaced on some vehicles because of design specifications or if the fuel tank is corroded or otherwise damaged.

Now there are a couple of things you can do to help your fuel pump last longer. One pump killer is contamination in the fuel tank. Sometimes this comes from the fuel itself. Buying fuel at a reputable station will help make sure you are putting clean fuel into the tank. Older vehicles tend to have more sediment in the tank from years of rust or corrosion from the tank itself. The tank may need a thorough cleaning or replacement.

Another thing you can do is refill your tank when it gets down to about a quarter full. The fuel pump is submerged in the fuel which cools and lubricates it. When the tank runs low, the pump has to work harder to suck up the fuel from the bottom and there is no fuel to cool it. This can lead to premature wear.

When the day comes that your fuel pump needs to be replaced, Pro Muffler & Brake Shop Inc in Benton Harbor will use a quality replacement pump that meets or exceeds your vehicle manufacturer’s specifications. The entire assembly should be replaced. We’ll be sure to install a replacement pump that is compatible with your fuel type. For example, if you have a FlexFuel vehicle that can run on gasoline with up to 85% ethanol content, your fuel system components – including the fuel pump – must be able to withstand the corrosive effects of high alcohol content fuel.

PCV Valve Replacement

Pro Muffler PCV Valve Testing
Pro Muffler & Brake Shop Inc Tech Question:
What is a PCV Valve and should I test it?

Pro Muffler & Brake Shop Inc Tech Answer:

The PCV valve is a little, inexpensive part that does a big job for Benton Harbor and our environment here in Michigan. PCV stands for Positive Crankcase Ventilation. The crankcase is the bottom area of the engine that holds the oil. When the engine’s running, fuel is burned to generate power. Most of the exhaust from combustion goes out through the exhaust system. But some exhaust blows by the pistons and goes into the lower engine, or crankcase.

These hot gases are about seventy percent unburned fuel. This can dilute and contaminate the oil, leading to damaging engine oil sludge. It can also cause engine corrosion. At high speeds, the pressure can build up to the point that gaskets and seals start to leak. Over time, the vented gases will gum up the PCV valve and it won’t work well. That can lead to all of the problems I’ve already described, oil leaks, excessive oil consumption and reduced .

Fortunately, it’s very easy to test the PCV valve and quick and inexpensive to replace at Pro Muffler & Brake in Benton Harbor. Even so, it’s often overlooked because many people in Benton Harbor don’t know about it. Check your owner’s manual or ask our friendly and knowledgeable technicians at Pro Muffler & Brake. If this is the first time you’ve heard of a PCV valve, you might be in line for a replacement.

Please ask us at Pro Muffler & Brake about your PCV valve. For the price of a couple of burger combo meals at your favorite Benton Harbor drive-up window, you can avoid some very expensive deep engine repairs.

How long will my battery last in the cold weather?

Pro Muffler & Brake Shop Inc Tech Question:
Due to the cold weather, how often should I replace my battery?

Pro Muffler & Brake Shop Inc Tech Answer:

Car batteries last longer in cold climates than in warm. Cold starts put a greater demand on batteries, but heat is also a big factor in Benton Harbor. The fact is that, on average, 70% of batteries fail within four years. Many experts recommend replacing your battery every five years. This can help avoid you being stranded with a dead battery as well as undue wear on your alternator.

At Pro Muffler & Brake Shop Inc in Benton Harbor, we can test your battery and alternator to see if they need to be replaced. We may find they both test out as being OK – but for some other reason things are working properly. Remember we said that the serpentine belt drives the alternator? Let our team of friendly and knowledgeable service techs at Pro Muffler & Brake Shop Inc get to the root of your problem.

Dead battery? Check your alternator

Pro Muffler & Brake Shop Inc Tech Question:
My battery keeps going dead. I had it tested and it is fine – what could be the problem?

Pro Muffler & Brake Shop Inc Tech Answer:

Well, your could be caused by several things. Let’s start with a likely suspect: your alternator. The alternator is like a little electrical generator. It is spun by the serpentine belt on your engine and makes electricity. This electricity is used to power the electrical systems required to run your vehicle. It also powers all of your electronic accessories like your stereo, navigation, heated seats, and air fans, as well as charging all the electronics you have plugged in.

After the alternator has preformed all that, any electricity that’s left over is used to charge your battery. You can see where we’re going: if the battery isn’t getting enough electricity to stay charged the problem may have something to do with the alternator.

Now it could be that the alternator is bad – they do wear out over time. There are a number of failure points within the alternator, but in practice, it is less to simply replace the alternator than to take it apart and repair it.

At Pro Muffler & Brake Shop Inc in Benton Harbor, we can test your alternator to see if it needs to be replaced. We may find that the alternator tests out as being OK – but for some other reason it’s not putting out enough electricity to keep the battery charged. Remember we said that the serpentine belt drives the alternator? Well the problem can often lie with the serpentine belt system.

The serpentine belt transfers power from the engine to the alternator. When the belt wears away to a certain point, it is no longer able to provide enough grip and the belt can slip on the alternator pulley so that it is not spinning enough to generate all the electricity that your vehicle needs.

A possible problem related to Benton Harbor a worn serpentine belt is the tensioner pulley. This pulley provides tension on the serpentine belt so that it is tight enough to spin the alternator and other accessories. When the belt is too loose, it can slip on the alternator pulley and, once again, not enough electricity is made.

So, when you battery is going dead – test it. If the battery is still good – test the alternator. If the alternator is still good – inspect the serpentine belt and belt tensioner. Chances are good that your service center or the team of friendly and knowledgeable service advisors at Pro Muffler & Brake Shop Inc will get to the root of your problem.

Evaporative Emissions Control (EVAP)

EVAP_System_Overview_01.12

The purpose of an EVAP system is to capture vapors and direct them into the engine to be burned – kind of an on-board recycling program.

The EVAP system is a complicated network of hoses, valves, filters and such. Issues with the EVAP system are in the top 5 reasons for a Check Engine Light to be illuminated. Your friendly and knowledgeable Pro Muffler & Brake Shop Inc can pull the trouble codes and begin a diagnostic procedure to isolate the fault.

With the proper equipment, your can test the valves in order to trace a blockage. A low pressure smoke test can be performed to find any leaks. The repairs are then made to get the EVAP system working again and to reset the Check Engine Light.

While EVAPs don’t generally lead to vehicle damage, the fact that they trigger the Check Engine Light can mask other more serious problems if left unaddressed. After all, there are hundreds of conditions that can trigger a Check Engine Light – but there is only one light. So if the light is on because of an EVAP issue you haven’t fixed and another arises, you won’t be alerted to the new condition because the light is already on.

Of course, if you live in a jurisdiction in that requires emissions testing to register your vehicle, you won’t pass the test until you make the repairs. An EVAP trouble code could be caused by something as simple as a loose or worn gas cap or a leak in a hose, to problems with a purge valve or even a rusty fuel filler pipe.

When your Check Engine Light comes on, bring your vehicle into Pro Muffler & Brake Shop Inc in and let us check it out. Your Pro Muffler & Brake Shop Inc will be able to diagnose the problems and work out a plan to address anything that is uncovered. There’s peace of mind for that comes from knowing what is wrong and taking care of it.

Exhaust Service – Failed Emissions Test

failed-emissions-test-promuffler-brake-benton-harbor

Pro Muffler & Brake Shop Tech Question:
My car failed its emissions test – what do I need to do?

Pro Muffler & Brake Shop Answer:
Let’s get this out of the way: a leak in your exhaust system could be deadly. If Benton Harbor motorists smell exhaust in the passenger cabin or hear an unusual exhaust sound, they should get their exhaust system checked and repaired. Talk to your friendly & knowledgeable Pro Muffler & Brake Shop service advisor This is vital: Carbon monoxide in your exhaust is odorless, colorless and tasteless can be fatal to you and your passengers so don’t delay if you suspect and exhaust leak.

There could be a number of reasons for a failed Michigan emissions test so some vital diagnostic work is in order. A common reason for Benton Harbor auto owners is that the catalytic converter has failed. The catalytic converter removes some of the harmful elements in exhaust.

When a catalytic converter fails it must be replaced, which isn’t cheap for Benton Harbor auto owners. Many Benton Harbor folks stop there – but the converter failed for a reason. There may be any number of engine run conditions that led to the failure. It would certainly be smart to have your friendly & knowledgeable Pro Muffler & Brake Shop technician diagnose the cause so that you don’t end up with another pricey catalytic converter replacement down the road.

Oh, and that Check Engine Light that so many Benton Harbor motorists ignore: It might just be illuminated for a an important condition that could lead to catalytic converter damage. Have your Pro Muffler & Brake Shop technician get to the bottom of any check engine light situation.

Check Engine Light Diagnosis

check-engine-light-promuffler-brake-benton-harbor

Pro Muffler & Brake Shop Tech Question:
My check engine light is on. What should I do?

Pro Muffler & Brake Shop Answer:
Many Benton Harbor drivers have had their check engine light come on. It’s an amber colored light that shows on your dashboard. In newer vehicles it might just be a problem with your gas cap not being screwed on tight enough (or a worn gas cap), causing the vehicle to fail the self-diagnostic evaporative emission test. All you need to do is go to your gas cap and verify that it is tight. If that was the problem, the light will turn off and everything will be fine within one or two days.

Resist the temptation to have someone “clear” the codes to turn off your auto check engine light. This erases important diagnostic information that your friendly & knowledgeable Pro Muffler & Brake Shop technician needs to diagnose the underlying problem for the check engine light – and any other pending problems that may be stored in the auto computer.

If the problem is still there – you still see the light – bring your auto in to Pro Muffler & Brake Shop in Benton Harbor and have your check engine light checked out as soon as possible.
