The Muffler & Go Guide to Vehicle Diagnosis

Modern Fenton vehicles have several computers on board that control all kinds of things like engine functions, transmission shifts, traction control, anti-lock brakes, stability control, emissions – and on some vehicles, even steering, braking and the throttle.

Think about that for a minute – things that used to be controlled by simple mechanical connections now have electronic controls that rely on computers, software and sensors. It's no wonder that when something goes wrong with their vehicle it can be pretty complicated for Fenton drivers to track down the source of the problem.

To help your service advisor at Muffler & Go figure out what's wrong, your vehicle is equipped with on-board diagnostics. The Check Engine light comes on to tell you there's a problem and the engine management computer stores a trouble code. Your friendly and knowledgeable Muffler & Go technician connects a scan tool to your vehicle's diagnostic port and retrieves the trouble codes as well as other important data.

Trouble codes are like clues for the technician to follow as he diagnoses what's wrong with your vehicle. In a way, it's like going to your Fenton doctor with a problem. She'll run some additional tests and gather the information she needs to make a diagnosis and form a treatment plan. How much a vehicle diagnosis costs at Muffler & Go in Fenton depends on how much time it takes to sort out the symptoms and find the underlying problem.

Water Pump

Your cooling system is very important. It circulates coolant through the radiator and your engine to protect your vehicle from overheating. There are five main components to the cooling system:

• the radiator
• the radiator cap
• the hoses
• the thermostat
• the water pump

The water pump's like the heart of your cooling system, circulating the fluid throughout your vehicle. It's a small pump that's driven by the engine; usually by belt, but sometimes by a chain or gear.

The water pump only operates when the engine's running. Water pump failure is pretty routine. We see it often at Muffler & Go. Some start failing at around 40,000 miles/64,000 km, but most fail by 100,000 miles/160,000 km. Consult your owner's manual or friendly and knowledgeable service advisor at Muffler & Go to see what's recommended.

Since a water pump either works or it doesn't, you need to change it when it fails. Water pumps fail in one of two ways: the bearings fail or they begin to leak. It's possible to have a leak from a cracked water pump, but it usually leaks at the gasket where it attaches to the engine.

So how can Fenton drivers tell when the water pump is failing? If you can hear a low-pitched grinding sound coming from the water pump, it's got a problem. If you can see coolant in that area, you've got a leak.

Some water pumps are driven off the timing belt. They might be under a plastic cover so you can't see the water pump. Look for coolant on the driveway. If you see some, have Muffler & Go check it out.

Most timing belts need to be changed at 60,000 miles/97,000 km – some longer. It's a good idea to change your water pump at the same time if it's one of those that's driven off the timing belt. To start with, 90% of the work's already done with the timing belt change. And if you don't and develop a leak later, you'll have to change the belt again along with the water pump because the belt will have been contaminated by the leaking coolant.

Muffler & Go can replace a failed water pump with a brand spankin' new one or with a rebuilt pump. Rebuilt will save you some money, but ask your service advisor at Muffler & Go what he thinks. Don't feel too bad if your water pump gives out. They will all wear out eventually. We can get you back on the road and on with your life.

10 Services Fenton Drivers Often Overlook

We live such busy lives nowadays: work, social events, running the kids all over Fenton. Some days it's all we can do to keep track of everywhere we need to be. That's why you've gotta be organized. Smartphones, calendar apps - we have to keep track of it all.

So let's talk about schedules. Specifically, automotive service schedules. And particularly, the scheduled services that are sometimes forgotten.

Here is a list of 10 service items that are often overlooked by Fenton residents. They're all very important and need appropriate attention. So here we go, in no particular order.

1. Power Steering Service
Be honest; have you ever thought of this on your own? Your power steering fluid gets dirty and builds-up moisture over time. Cleaning out your power steering system means that dirt and gum are removed and your power steering parts are protected from corrosion. Next time you're in for an oil change, ask your Muffler & Go service advisor if it's time for a power steering check-up.

2. Wheel Alignment
When your wheels are out of alignment your vehicle pulls to one side. It's pretty annoying, but it's also dangerous. And it causes your tires to wear out really fast, which is an unnecessary expense! Most owner’s manuals suggest you get your alignment checked once or twice a year.

3. Differential Service
Did you even know you had a differential? Well, you do - one, two or three in fact. Differentials are often called gear boxes and they're part of the drive-train that transfers power from your vehicle engine to your wheels. They don't need service that often, but you can't completely forget them. Check with your friendly and knowledgeable Muffler & Go service advisor.

4. Cabin Air Filter
More and more cars these days have cabin air filters (a great feature, in my opinion) to clean the air in the passenger area where we sit. They filter out dust and pollen. When they're clogged up, they can get smelly. Change your cabin air filter on schedule to enjoy fresh, clean air, which can also help with allergies.

5. Timing Belt Replacement
Most cars and some vans and trucks driven around the Fenton area have timing belts. Without going into a lot of detail, let's just say that your car won't run without it – period. And if it breaks while you're driving, it can do thousands of dollars’ worth of engine damage. Check your owner's manual or speak with your Muffler & Go service advisor. If you're approaching 60,000 miles or 100,000 kilometers; definitely look into it right away.

6. Transmission Service
Transmission service is very basic, but it's often forgotten by Fenton drivers. Your vehicle transmission needs clean fluid from time to time to keep operating efficiently and avoid pricey repairs.

7. Air Conditioning Service
Most of us don't think about our air conditioning until it fails on a hot day in Fenton. If you're lucky, you just need to add refrigerant. If you're not, some of the components may have been ruined. Of course, these components are not cheap. Regular air conditioning service at Muffler & Go in Fenton adds clean refrigerant which cools and lubricates your air conditioner and conditions the seals.

8. Brake Service
No we're not talking about squealing, grinding brakes here. We're talking brake fluid. Over time, the fluid gets a lot of water in it. Because water compresses differently than the brake fluid, your brakes won't work as well. It may even get dangerous. The water can also rust out brake system components and then your brakes can fail altogether. Check with your Muffler & Go technician for recommendations.

9. Coolant System
Another thing that's so easy for Fenton drivers to forget about: When you don't change your antifreeze on schedule it becomes corrosive. Fresh coolant contains additives that maintain the pH balance in the coolant. These additives wear out and the fluid in the radiator can actually eat holes in the radiator or hoses. Then you're stranded - bummer.

10. Fuel System Cleaning
In these times of high fuel prices, fuel system cleaning is vital. Fuel gums up a bunch of parts as it moves from the gas tank and through the engine. A thorough fuel system cleaning at Muffler & Go in Fenton will keep clean gas flowing into the engine. Your fuel injectors also get gunked up over time and need to be cleaned. Having your fuel system cleaned on schedule at Muffler & Go will really help your fuel economy.

There you have it: 10 services that are often overlooked by Fenton residents. Did you know that a recent survey showed that 90 percent of vehicles on the road have at least one scheduled maintenance service that hasn't been performed? Considering our busy lives, we're not surprised. Muffler & Go can help with any of these services. Give us a call or come see us.

When Are Your Tires Worn Out?

Hey Fenton area drivers, are your tires worn out? What is the standard for our MI streets? How can you tell on your vehicle?

While there may be legal requirements for the Fenton area, there are safety concerns that go beyond meeting minimum replacement mandates.

Two-thirty-seconds of an inch is the depth of the tire tread wear indicator bars that US law has required to be molded across all tires since August 1, 1968. When tires are worn so that this bar is visible, there's just 2/32 of an inch – 1.6 millimeters – of tread left. It's that level of wear that's been called into question recently.

We're referring to the tread depth on a tire, it can't move surface water out of the way and you start to hydroplane.

In a safety study, a section of a test track was flooded with a thin layer of water. If you laid a dime on the track, the water would be deep enough to surround the coin, but not enough to cover it.

A car and a full-sized pick-up accelerated to 70 miles per hour, or 112 kilometers an hour, and then made a hard stop in the wet test area. Stopping distance and time were measured for three different tire depths:

• New tire tread depth
• 4/32 of an inch, or 3.2 mm
• 2/32 of an inch, or 1.6 mm

So what happened with the 2/32 inch/1.6 mm tires on the car? Get this – when the car had traveled the distance required to stop with new tires, it was still going 55 mph/89 kph. Stopping distance was nearly doubled to 379 feet/116 meters, and it took 5.9 seconds.

Wow! That means if you barely have room to stop with new tires, you would hit the car in front of you at 55 mph/89 kph with the worn tires.

Now, with the partially worn tires – at 4/32 of an inch, or 3.2 mm – the car was still going at 45 mph/72 kph at the point where new tires brought the car to a halt. It took nearly 100 feet, or about 30 meters, more room to stop and 1.2 seconds longer. That's a big improvement. We can see why Consumer Reports and others are calling for a new standard.

Of course, stopping distances were greater for the heavier pick-up truck.

How do you know when your tires are at 4/32 inch or 3.2 mm? Easy; just insert an American quarter into the tread. Put it in upside down. If the tread doesn't cover George Washington's hairline, it's time to replace your tires. With a Canadian quarter, the tread should cover the numbers in the year stamp.

You may remember doing that with pennies. A penny gives you 2/32 inch, or 1.6 mm, to Abraham Lincoln's head. The quarter is the new recommendation – 4/32 inch, or 3.2 mm.

How do people feel about replacing their tires earlier? Well, tires are a big ticket item and most people want to get the most wear out of them that they can. But do you want that much more risk just to run your tires until they are legally worn out?

For us, and we would guess for many, the answer is "no".
