Always on Guard (TMPS)

One of the most important things you can do to keep your vehicle running safely is to make sure your tires are properly inflated.  If one or more is vastly over- or underinflated, that has the potential to cause major handling problems and may result in a dangerous accident.

All vehicles in recent years are equipped with Tire Pressure Monitoring Systems, or TPMS.  One system uses small sensors in the tires that continually check the pressure in each tire.  That sensor sends a signal to computers in your vehicle which turns on an instrument panel light warning of low pressure when at least one is very low. Or it may update a numeric reading on your instrument panel which gives you an approximation of how many PSI (pounds per square inch) of air is in each tire. 

Another system works with your antilock brake system to measure the size of your vehicle’s tires.  When one wheel is going faster than another, it will spin faster. A computer sees that and alerts you that tire’s diameter is smaller than the others and therefore must be underinflated.

No matter what system you have, it’s also helpful for you to know how much pressure each tire is supposed to be inflated to.  You can find that on a label on the driver’s side door sill. In addition, the TPMS system should not be used as a substitute for checking your tires with a tire gauge since the TPMS accuracy usually isn’t quite as precise.  Keep in mind that tire sensors can fail, so each system acts as a backup for the other. 

Since many vehicles these days don’t have spare tires, it’s good to know that your TPMS can warn you if you have a leak in one of your tires.  If you get a low-pressure warning, many systems will tell you which tire is low, so you can do your own visual check.  Often you can see if you’ve picked up a nail or a screw if it’s sticking out of the tread or near the sidewall.

Being able to receive an early warning from your vehicle of abnormal tire pressure may give you a chance to safely drive to a service center before your tire slowly goes completely flat (which can ruin the tire and badly damage the rim). It also may ultimately prevent you from being stranded somewhere with a flat tire or, most importantly, having a sudden blowout on the road.

The Last Gas (Fuel Pump Replacement).

You're heading down the road and you notice your vehicle is sputtering, like it's running out of gas.  But the gauge show's it's still got a quarter of a tank.  So what gives?

It could be that your fuel pump is failing, meaning your engine is not getting enough gas to run properly.  While fuel pumps are built to last a long time, sometimes they fail.  Other symptoms you may have a bad fuel pump include your vehicle stalling and then refusing to start again, the engine overheating or a hum or whirr coming from around the gas tank.  Or, your Check Engine light may come on.

Most fuel pumps are in the gas tank. They have a small electric motor in them.   When you bring your vehicle to our service center, a technician will run tests to confirm the fuel pump is getting power to it but has failed.  Some vehicles have an access panel so the fuel pump can be removed and replaced. 

But in some vehicles that don't have that access panel, the technician has to drain the fuel and take the tank out of the vehicle to be able to replace the fuel pump inside.  Some parts such as brackets that attach the pump can be reused when the new fuel pump is installed.  Most technicians will recommend replacing the fuel filter at the same time the fuel pump is changed out.

If the technician has to remove the fuel tank, they'll also check for rust and corrosion and replace any affected parts.

Keep one thing in mind - your vehicle's fuel pump is in the fuel tank because it's kept cool and lubricated by the gasoline in the tank.  Try not to let your fuel level go below a half or quarter of a tank to maximize the life of your fuel pump.  Also, try to use Top Tier gasoline that has higher standards than some other fuels.  Your engine—and fuel pump—will thank you.

A Head Start on Starting (Battery Testing)

If your vehicle isn't starting or doesn't sound like it used to when you crank it, the culprit may be the battery.  You may have left a light on, or something plugged into one of charging ports.  Maybe you accidentally left your vehicle in the "on" or "accessory" position when you last got out. Maybe you've left it in the garage or driveway for a long time without starting it.  That can spell the end for a vehicle battery.

It's also possible that your battery is just simply too old. There's no standard lifespan of a battery, but 3-5 years is about average, even though some people only get 2 and heavier duty batteries may last many more. It's possible your battery is defective, too.  And it could be your vehicle's charging system isn't recharging the battery. 

Whatever the cause, if you're having problems with your battery, it's a good idea to bring it in and have us perform a thorough battery test.  With state-of-the-art testing equipment, a technician will see if there's a bad cell in the battery or if it can be recharged.  We will also look at the date it was made. 

At the same time, the technician will look at the whole charging system, including the alternator, starter, cables, and connections.  From there, the service advisor can go through your options. 

Your best chance of not getting stranded by a dead battery is to have your system checked as part of a regular maintenance plan.  That should give you a head start on dependable starts.

Straight to the Point (Alignment Signs of Problems)

It’s just common sense that your vehicle will drive better if all the wheels are lined up with each other and the road the way the engineers intended.  When they’re not, that is called being out of alignment.   Here are some signs that your alignment has problems.

• Your steering wheel isn’t straight when your vehicle goes straight down a straight road. This one’s pretty easy to notice.  If your vehicle’s logo on the wheel is tilted, that’s probably not the way designers wanted it to be. Bring it in and have us check it out.
• Your steering wheel is vibrating on a smooth road or when you are accelerating.  While this could be caused by several different things, one possibility is misalignment.  If your steering wheel is shaking, it should be examined by a trained technician.
• Your vehicle is pulling to one side without you wanting it to.  Sometimes the configuration of the road will cause it to pull slightly left or right.  But if you find yourself constantly correcting course to keep your vehicle headed straight down the road, that’s worth having us look at your alignment.
• You’re going through tires like there’s no tomorrow. The tread on your tires should be wearing nice and evenly from the outside to the inside of the tire.  If the wear isn’t even, it could be your vehicle needs an alignment.

We have equipment designed to quickly and accurately measure your vehicle’s alignment.  We can make precise adjustments to make sure you are headed straight where you want to go.  Have your alignment checked regularly. It can help prevent more serious problems in the future and make your vehicle drive as beautifully as you remember it used to.
