Don't Start with That (Bad Starter Motor)

We've all heard that expression, "That's a non starter." When it comes to your vehicle, that's not music to a driver's ears. That sickening sound when you start the ignition and instead of hearing the engine crank, you hear it slowly turn over and your dash lights go dim. 

There can be many reasons a vehicle won't start, so here's a little history of how the starter came to be an important component of modern vehicles.

You have to move the engine's components to start it. The first cars had a crank that the driver would insert into the front, then start turning things over by hand.  When the engine started, you had to release that crank immediately or risk a broken arm.  Yes, it happened many times.  So, they came up with a better idea: an electric starter, which was a big advance in automotive technology.

With this system, an electric motor rotated a series of gears that turned the gasoline engine's crankshaft so its pistons and parts moved and the engine drew in air.  While this happened, electricity went to the spark plugs and fuel headed to the cylinders.  When the gasoline engine caught, the starter quickly disengaged. Hey, no more broken arms!

Modern systems use the same principle, so when your vehicle won't start, here are a few things to look out for that might point to the starter. 

If the engine turns over s-l-o-w-l-y, it may mean the electric starter motor may just be wearing out and doesn't have enough cranking power.  Bushings, brushes, wire windings and a special switch called a commutator may be going bad.

If when you engage the ignition you hear a faint click, that could be a symptom one or more of the starter's components have failed. If you hear a loud click, it could mean that an electrical switch called a solenoid may not be switching the motor on.

If you hear your engine start to turn over but then it stops and is followed by a grinding sound, some gears may not be meshing the way they should.

There may be many more causes (bad alternator, relay, battery, engine, key fob), so this is when it's time to turn it over to your service facility.  Sometimes they can send out their own tow truck or recommend a reputable towing company.

But it's best not to let it get to this point.  Starter problems often give you advance warning that there is a problem with "almost" not starting or "almost" not turning over.  So when you see that very first sign, "start" on over to talk this one over with your service advisor.  The opposite of a "non-starter" is a starter, and that is music to anyone's ears.

Keeping Your Fenton Air Fresh When Driving With a Clean Cabin Air Filter

Pop quiz: What is a cabin air filter?

A. A filter for your Fenton house?
B. A fresh, piney scent?
C. A filter for the passenger compartment of your car?

Clever you, it's C.

A cabin air filter cleans the outside air before it comes into the passenger compartment of your vehicle. It filters out common MI air particles like dust, pollen, spores, bacteria, pollutants, exhaust gas, odors and even sparrows.

These high tech filters can block particles larger than 3 microns. By contrast, a grain of sand is about 200 microns.

Not all Fenton vehicles have cabin air filters. They are fairly new on the scene in MI. Last check, about 40 percent of new vehicles sold in Fenton come with cabin air filters, but the number is growing every year.

Cabin air filters make driving a lot more pleasant for people in Fenton. Your vehicle can be a haven during our MI allergy season with very little dust and pollen getting into the cabin. Of course, like all filters, the cabin air filter eventually gets clogged. When this happens, your heating and air conditioning flow can become restricted. The filter can even get kind of smelly.

Check your owner's manual for replacement guidelines. If your vehicle owner's manual doesn't mention your cabin air filter, ask your friendly and knowledgeable service advisor at Muffler & Go for a recommendation. It's usually every year or 12,000 miles /19,000 kilometers. Change it sooner if you drive in dusty conditions around the Fenton area, or if you start to notice a funky smell coming from your vents.

The team at Muffler & Go urges Fenton drivers to keep their cabin air filter cleans. It may not help with your brother-in-law in the backseat, but it will make your driving experience around Fenton more enjoyable.

Come by and we'll take a look at your cabin air filter for you.

Upsizing Wheels and Tires With Muffler & Go

Many Fenton drivers want to accessorize their vehicle - you know, make it theirs. One of the easiest ways to get a custom look is to get some new wheels. There are thousands of wheel designs at Fenton area tire shops to get you the look you want. And for many Fenton drivers, that look includes bigger wheels. It used to be that cars came from the factory with 15 or 16 inch wheels. Now 16, 17 and even 18 inchers are standard. And the factories are offering optional wheel packages up to 20 inches or more.

So let's talk about what to consider when you want to upsize your wheels. It's not exactly a DIY project, so you need to know a thing or two before you get started. The most important term to know is rolling diameter. The rolling diameter is simply the overall height of your tire. Unless you want to modify your vehicle suspension, you'll want to keep your rolling diameter the same when you upsize your wheels.

Let's think about those three golden doughnuts in front of you. They're all about the same size. So if we pretend they're tires, they would have the same rolling diameter. The doughnut hole is the size of the wheel. Now pretend we've made the hole bigger on some. That's like having a bigger wheel - but the rolling diameter is the same.

It's important to keep the rolling diameter the same for several reasons. First of all, if the tire is bigger, it might not fit in the vehicle wheel well. Next the speedometer, odometer and anti-lock brake system are all calibrated for the factory rolling diameter. In order for your anti-lock brakes to work properly, the rolling diameter must stay within 3% of the factory recommendation. If you ignore that, you run the risk that your anti-lock brakes won't work properly.

Some have vehicles with electronically-controlled suspension that will be negatively affected by changing the rolling diameter. Let's think about the doughnuts again. You see, as the size of the wheel gets bigger, the sidewall gets shorter. The tire holds less air, so the sidewalls are made stiffer to compensate.

Low profile tires from top manufacturers use special compounds that give the sidewall the strength it needs without compromising ride quality. As you increase your wheel size, you'll typically get a slightly wider tire. This means that you have a larger contact patch. The contact patch is part of the tire that contacts the road. Because there's more rubber on the road, the vehicle will handle better. And braking distances will be shorter. A lot of Fenton folks with trucks or SUVs love the extra control.

MI drivers need to watch out that the contact patch isn't so big that the tires rub in turns or over bumps. What we're talking about here is fitment. Your tire professional at Muffler & Go can help you get this right. He'll install your new wheels, add spacers if needed to make sure your brakes fit inside your new wheels and get you rolling.

Also, if you drive off-road in MI a lot, you may need a higher profile tire to protect your new rims. And make sure your new tires have the load rating you need if you tow a trailer or haul heavy loads. Again, your tire professional at Muffler & Go knows how to help.

And don't forget about tire pressure. If you have larger rims, your new tires will hold less air and they'll need to run a slightly higher pressure. Forget that and you'll wear your tires out fast. Finally, get an alignment at Muffler & Go after you get your new shoes.

The Byte Stuff (Your Vehicle's Computers)

Nobody has to tell you that computers are a part of so many things in our lives.  Smartphones, kitchen appliances, vacuum cleaners, televisions.  You name it—it has a computer in it.  And your vehicle is no exception.

The earliest cars relied on the technology of their time, and there was no such thing as a computer.  But now, it's not unusual for a vehicle to have as many as 150 computers in it.

They perform a variety of functions. An important one is diagnosing your vehicle's problems.  There are various sensors throughout modern vehicles that measure thousands of data points.  When something is not working correctly, they send a signal to another computer that stores that information. The data can be read by someone who has a special computer that plugs into a port in your car.  It displays certain codes that help technicians track down the culprit. 

But it's not just the diagnostics that are computerized.  Everything from your vehicle's fuel injection to anti-lock brakes is.  Convenience features such as power windows, rain-sensing windshield wipers, a wi-fi-hot spot, streaming video and navigation are all sophisticated computers.  Then there are the safety features; air bags, traction control, automatic emergency braking and a host of others are all dependent on computers.

It is important that those computers work correctly because they interface with many of the other computers on board.  To properly diagnose problems with those computers requires training and special equipment. Your service facility has invested considerable resources into both, and they are equipped to properly evaluate and repair and/or replace malfunctioning components. 

Some lament the days when backyard mechanics could pull out their tools and do their own repairs.  Those days are fast disappearing with the computerization of vehicles.  But look at the bright side.  Your vehicle does so much more, has so many more features and travels far more safely than those past generations drove.  And they're bound to get better and more sophisticated down the road.
