Heat and your Tires (Tire Pressure Monitoring System)

Posted December 25, 2022 9:51 AM

With hotter weather and brutal heat waves becoming more common, the pressure in your vehicle's tires goes up.  After all, heat causes air to expand, and the air in your tires follows the laws of physics. Overinflated tires can reduce your vehicle's traction, cause a hard, punishing ride and make your tires wear out faster; all are important safety issues.

Four out of every ten drivers rarely check tire pressure. Some rely on their vehicle's tire pressure monitoring system (TPMS) to keep an eye on proper tire inflation.  But it's not designed to do that.

TPMS is a safety feature that has been required on vehicles made in 2008 or later, using sensors in the wheels that alert you to tire pressure problems.  That warning can be a light on your dash, a digital message or a readout of the pressure in each individual wheel.  But a study showed that more than 40 percent of drivers don't even know what the tire pressure monitoring light symbol looks like!

One looks like a horseshoe with an exclamation point in the middle.  The other looks like an overhead view of your vehicle with the tires at all four corners.  They may even show the inflation number (usually in pounds per square inch, or PSI).

The TPMS is designed to alert you that your tires aren't inflated within certain parameters, but the system shouldn't be a substitute for frequently having your tires checked with a tire gauge.  A TPMS light is only required to come on when a tire is 25 percent under the recommended tire pressure; by that time, you're driving on an unsafe tire and causing excessive wear.

Have your vehicle checked regularly by our professionals, and that includes tire pressure checks.  If you do see the tire pressure warning come on, have our service center look at it soon.  You may have a tire with a problem or the TPMS system may not be working right. 

Either way, since your tires are the only contact your vehicle has with the road, your safety depends a great deal on your tires being in top shape and correctly inflated.  Keep your tires properly inflated and your TPMS working to alert you of any problems. And that's not just a lot of hot air.

Refresh Your Brakes (Brake Fluid Exchange)

Posted December 18, 2022 8:26 AM

Brakes are one of your vehicle's most important safety components, and you may have noticed that they don't stop as surely as they used to.  Maybe it takes you applying a little more pressure to them than before, or perhaps you get the feeling that they're not stopping you as quickly.

Those could be signs that your brake fluid needs changing.  Hydraulic brake systems use a fluid that enables the brakes to apply their stopping power to the wheels.  That fluid can wear out, degrade, become contaminated or pick up air and moisture.  All those can eventually contribute to brakes that feel sluggish. Driving with old, worn-out brake fluid may also shorten the lifespan of other braking components.

Our technicians can evaluate your brake fluid to see if it needs changing. Your vehicle's manufacturer recommends how often that should be done, and when it needs changing may depend on how and where you drive. Our technicians can check the condition of your brake fluid when you have your regular oil changes. 

A technician will remove the old fluid and replace it with the type the vehicle manufacturer recommends. They will also bleed the air from the brake system, check it for any leaks and inspect other components such as the hoses, rotors and brake pads. Because brake fluid is combustible and toxic, it's important that it be disposed of properly so as not to create environmental damage. 

And just a reminder that if you continue to drive with old, contaminated brake fluid that's past its lifespan, other components of your brake system can fail.  Let's face it. Brakes that don't stop you when you need them can endanger your life—and the lives of those near your vehicle.

Go With the Flow (MAF Sensor Replacement)

Posted December 11, 2022 7:39 AM

A driver brought her vehicle into the shop the other day and told us how she was getting lousy fuel economy and that the engine was running rough.  Plus, the Check Engine light was on.  Our technician checked the code the engine had generated (why the Check Engine light was on) and found the problem.  It was a faulty Mass Air Flow sensor, MAF sensor for short.

This MAF sensor is an important part of your vehicle.  What it does is calculate the amount of air going into your engine.  As you may know, air is taken into your engine where it's mixed with fuel.  Then, the spark plugs fire, that explosive fuel/air mixture detonates, and all these sequential explosions together provide the power to get your vehicle moving down the road. 

It makes sense that if the MAF sensor isn't sending the engine's computers the correct information on the amount of air going in the engine, the fuel/air mixture isn't going to be right. It will either too rich (too much gasoline for the amount of air) or too lean (not enough gasoline for the amount of air).

In this driver's case, the MAF sensor was damaged and needed to be replaced.  Another thing that may cause the MAF to give an incorrect reading is if its wires are dirty or faulty.  So, replacing or cleaning the wires important as well.

Other symptoms that your MAF sensor is bad? If your engine hesitates when you step on the gas, it stalls, or your vehicle is jerky when you accelerate. 

A malfunctioning MAF sensor is not just bad for performance.  Driving with your vehicle in that condition can cause more damage to your engine.  When you bring your vehicle in for us to check, a technician will thoroughly examine your engine to make sure all issues are taken care of.

Straight to the Point (Alignment Signs of Problems)

Posted December 4, 2022 8:49 AM

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.

So we started hearing a high pitched noise from the back brakes on a trip to anchorage from seward, after checking out another local shop who was extremely rude I jumped on yelp and stumbled across these lovely people. They got me in right away just to take a peek, saying they couldn't fit me in till later but would take a look just to see if it was still safe to drive and what to expect. They were curtious, friendly, honest and fair. I highly recommend this establishment! Thanks for getting us back to Seward safely xoxo
