Pro Muffler & Brake Shop Inc Tech Question:
I’m Collins. I had my engine go out and had to have it completely re-done at Pro Muffler & Brake Shop Inc. What could I have done to prevent this?

Pro Muffler & Brake Shop Inc Tech Answer:
You’ve got to feel for Collins: an expensive major engine rebuild is pretty extreme. It’s a tough situation to be in: maybe you’re still making payments on your vehicle and nobody wants to buy it with a blown engine, so you really have no choice but to pay the money to get it fixed.This is why your manufacturer and Pro Muffler & Brake Shop Inc have preventive maintenance schedules – to help you avoid major repairs. Suppose you don’t change your timing belt on schedule and it breaks. That can mean bent valves and a damaged cylinder head.Maybe you’ve skipped over the Pro Muffler & Brake Shop Inc recommendation to replace your coolant and end up with catastrophic overheating. It could be you’ve skipped a few too many oil changes and now sludge has built up in your vehicle to the point that expensive parts in your engine are being damaged.

Whatever the case, preventative maintenance can almost always mitigate the damage or stop it before it begins.Check your vehicle oil level every month and follow your recommended service schedules. And if you’re behind on any services, ask your friendly and knowledgeable pro at Pro Muffler & Brake Shop Inc to help you work out a plan to get caught up.

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.

Radiator Fans

radiator_fan_01

If you’re old enough, you’ve heard the term “fan belt”. Back in the day the radiator fan in your vehicle was turned by a belt driven by the engine. There are still belt driven fans – although most are now driven by the serpentine belt. But most vehicles now have electric fans that draw fresh air across the radiator to cool it.

As coolant/antifreeze circulates in the cooling system it captures heat from the engine and flows into the radiator. Air cools the radiator and the coolant in it before it flows back into the engine to pick up some more heat. Now your engine has an ideal temperature range in which it is most efficient: it shouldn’t be too hot or too cool. The electric radiator fans help maintain the ideal temperature.

A switch mounted in a cooling system passage checks the temperature of the coolant. If the coolant is at the low end of the range, the switch turns off the fan motor. When the coolant rises to a certain temperature, the switch turns on the fan. When you are running the air conditioning, the radiator fan will likely be turned on as well to help reduce the extra engine heat created by the load placed on it by the air conditioner.

A lot of vehicles will actually have two radiator fans. One or both or neither may be running at any given time depending on the conditions. When you are cruising at highway speeds, the air rushing over the radiator and around the engine will help control the heat. By contrast, stop and go driving around town doesn’t generate much natural air flow so the radiator fans will be working hard.

You may have noticed the sound of the radiator fan running after you turn your vehicle off. This keeps the engine from heating excessively after it has been run and shut off.

Now the radiator fan motors and the switch are wear items that will eventually fail. If your temperature light comes on while driving, you have a problem with the cooling system. Your service technician can inspect your entire cooling system, including the radiator fans, to determine what is causing the indicator light. Of course, servicing the cooling system as recommended will help extend the life of all the components. Ask your service advisor at Pro Muffler & Brake Shop Inc if you are due for a cooling system service.

Severe Service

severe-service-promuffler-brake-benton-harbor

 

Simple Answers from Pro Muffler & Brake Shop: Severe Service:
What is a severe service maintenance schedule?

Pro Muffler & Brake Shop Answer:
When I was a kid in Benton Harbor, Sunday meant having a bath, getting dressed for church and then hanging up my Sunday clothes soon as we got home. Mom didn’t have to wash those clothes but once a month or so. Benton Harbor Now, Saturdays were another story entirely: catching lizards, splash contests in mud puddles and crawling through the brush with GI Joe. Those clothes went straight into the laundry basket. My Sunday clothes – easy use. My Saturday clothes – hard use. They required a different laundry schedule. Severe service maintenance schedules are kind of like that for Benton Harbor car owners. “Normal” driving has a regular schedule; “hard” driving has a severe service schedule. Service intervals are shorter on the severe schedule.

Most owner’s manuals will describe severe service as:
Stop and go driving
Short trips
Low speed driving
Extreme hot or cold
Dusty conditions
Carrying heavy loads
Towing

For most Benton Harbor people, some “severe” driving is part of their everyday routine. You can communicate with your friendly & knowledgeable Pro Muffler & Brake Shop service advisor about how you drive around the Benton Harbor area and see if your routine is closer to the regular or severe definitions and adjust your service intervals for things like oil changes, transmission and cooling system service.

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.

Time to Replace Your Engine Air Filter

Engine Air Filter

Clean, Dirty!

When driving around Southwest Michigan, your minivan engine needs clean air to burn the fuel – and it needs a lot. In fact, a typical vehicle needs about 216,000 gallons of air for every tank of gas. This is where your air filter becomes very important!

All that air passes through a filter that catches the dust and dirt. Eventually the filter gets completely full. Because the filter can only hold so much, dirt starts getting through. This dirty air passes through the mass airflow sensor, and starts to accumulate on the delicate sensor element. The mass air flow sensor measures how much air is getting into your engine. When the airflow reading is incorrect, your minivan engine doesn’t get the proper amount of fuel. It runs rough and doesn’t perform as well as it should.

Eventually, the sensor is so damaged it needs to be replaced – which is pricy. In fact you could buy a case or two of air filters for the cost of a sensor replacement.

Of course, that dirty air keeps on going through to your minivan engine where it’s burned along with the fuel, which dirties up your combustion chamber and increases harmful exhaust emissions – not a good thing for Benton Harbor air quality, not to mention our lungs.

When your knowledgeable Pro Muffler & Brake Shop service adviser brings out your dirty air filter and recommends a replacement, remember the cost and poor performance that can be waiting for you down the road if you neglect this simple Pro Muffler & Brake Shop service. Ask your adviser if it’s time to replace your engine air filter.

Why Is My Check Engine Light On?

The Check Engine Light strikes fear into the hearts of many in Southwestern Michigan and is totally ignored by just as many.
Let’s get the urgency issues out of the way first. If your minivan’s check engine light is flashing, that means that something is wrong that could cause severe engine damage. Naturally, drivers should get that taken care of right away at Pro Muffler & Brake Shop Inc.

If your check engine light is flashing, you shouldn’t drive at Benton Harbor highway speeds, tow or haul heavy loads.

If the light is glowing steadily, Benton Harbor auto owners should keep an eye on it for a day or two. If the light doesn’t go off, schedule an appointment with Pro Muffler & Brake Shop Inc to get it checked out.

An explanation on how the Check Engine Light works may be informative. Most of your minivan engine functions are controlled by a computer, not surprisingly, called an engine control computer. The computer is able to adjust many engine parameters for environmental conditions, engine condition and even the way you drive.

In order to make these adjustments, the computer relies on a network of sensors to provide data. The computer knows the proper operating range for each sensor. When a sensor reading is out of range the computer runs some tests and may turn on the Check Engine Light.

A simple example is a loose or missing gas cap. This may cause one of the sensors to read out of range. The minivan’s computer doesn’t know if it’s a serious condition that caused the reading or just a loose gas cap, so it stores a trouble code and turns on the Check Engine Light.

Now when you tighten up the gas cap the sensor readings will be in the correct range. The computer will keep checking on the report for a day or two. Since a bad reading didn’t come up again, it turns off the Check Engine Light. The computer will also try to make adjustments to compensate for some readings. If it can do so, it’ll then turn off the Check Engine Light. If the problem can’t be resolved then the light will remain on and you should get your minivan looked at Pro Muffler & Brake Shop Inc.

Your Pro Muffler & Brake Shop Inc technician will plug a scanner into the on-board diagnostic port and read the trouble code stored in the computer. The trouble code will give the Pro Muffler & Brake Shop Inc technician a starting place as he diagnoses the cause of the problem.

PCV Valve Replacement-Car Maintenance

Today, we are focusing on PCV valve replacement. The PCV valve is a little, inexpensive part  does a big job for your car and needs some looking after when it comes to car maintenance.  PCV stands for Positive Crankcase Ventilation.PCV Valve Replacement At Pro Muffler & Brake Shop Inc

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 in your minivan. At high speeds, the pressure can build up to the point that gaskets and seals start to leak.

Car owners need to know that 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 wasted gas.

Fortunately, it’s very easy to test the PCV valve and quick and inexpensive to replace it at Pro Muffler & Brake Shop Inc. Even so, it’s often overlooked because many drivers don’t know about it.

Check your owner’s manual or ask your Pro Muffler & Brake Shop Inc adviser. If this is the first time you’ve heard of a PCV valve, you might be in line for a PCV valve replacement.

Please ask us about your PCV valve. For the price of a couple of burger combo meals, you can avoid some very expensive deep engine repairs.

Serpentine Belt Replacement At Pro Muffler & Brake Shop Inc

Today’s Pro Muffler & Brake Shop Inc article focuses on your serpentine belt. Your serpentine belt is a long belt that’s driven by your engine. It winds around several accessories that power important automotive systems. Let’s go over them.

First, the serpentine belt drives your air conditioning system. Next, the belt powers the alternator.

The serpentine belt may also run the pumps for both the power steering and power brakes. Serpentine Belt Replacement At Pro Muffler & Brake Shop IncIn some minivans, power steering may have an electric drive and power brakes can be vacuum driven.

And, on many vehicles, the serpentine belt powers the water pump (on some cars, the water pump is powered by the timing belt).

Your Pro Muffler & Brake Shop Inc service technician can perform a visual inspection of the belt to see if it has any cracks that signal the belt could fail soon and will measure the amount of belt material to make sure there is enough.

Drivers should be aware that there’s a special, spring loaded pulley attached to the engine called the tensioner pulley and sometimes an extra pulley call the idler pulley. Their job is to make sure there’s a constant tension on the serpentine belt so that it doesn’t slip. The spring can become worn and no longer provide the necessary pressure to keep the belt tight. That’s why it’s often recommended that the tensioner, and the idler pulley if so equipped, be replaced at the same time as the serpentine belt.

All in all, the serpentine belt’s an important part for the function of your minivan. And it’s not that expensive to replace at Pro Muffler & Brake Shop Inc – so it’s good to do so before it fails.
