Heat and your Tires (Tire Pressure Monitoring System)

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.

Staying In Charge (Alternator Repair)

Seems like these days, we're hearing about more and more electric or hybrid vehicles.  Keep in mind that conventional gasoline internal combustion vehicles have important electrical components, too, and it's important to make sure they're operating at their peak.

In a vehicle with a gasoline engine, the part that keeps the battery charged is the alternator.  It converts the mechanical energy created by the engine into electrical power.  To do that, a shaft in the alternator has a pulley on one end that's driven by a belt that is turned by the engine.  A series of magnets then spins around coiled wires and it creates alternating current, or electricity. Your vehicle uses that to charge the battery that, in turn, keeps other electrical components in your vehicle working.

Here are a few signs that the alternator isn't doing its job right.  The battery keeps going dead, your instrument panel's battery light is on (it looks like a rectangle with a - and + inside and a couple of "terminals" on top), or your lights are dimmer than they usually are. You may also have a voltage gauge that shows  lower than usual power. If bearings in your alternator are seizing up, you may hear a grinding noise coming from your engine compartment. If you have any of those signs, bring your vehicle to us so we can check your electrical system.

A technician will run diagnostics on your alternator, the cables and the battery. Because the alternator is driven by a belt, the technician will check what shape all the drive belts are in.  Plus, we'll see how much electricity the alternator is putting out. 

If your alternator has failed, it can be replaced with a new or a remanufactured one. Speak with your service advisor about which will best suit your needs. Oh, and keep in mind that sometimes other parts may have to be replaced at the same time. For example, if your alternator's bearings froze up, that may have damaged the drive belt, and it may have to be replaced at the same time.

The Edible Engine

You may have had a friend whose vehicle was the victim of hungry rodents.  After all, mice, rats and squirrels—even rabbits—have been known to gnaw on wires in engine compartments, causing vehicle electrical systems to go haywire.  They can disable a vehicle completely and be very expensive to fix.

In 2017, some drivers noticed their vehicle's wiring was being chewed and found out the automaker was using a relatively new material for covering their wires: soy.  Many of the repairs to their new vehicles weren't covered under warranty by the manufacturer when it was discovered rodents were eating the wiring.  So the owners filed a class action suit, saying the soy covering was essentially baiting the critters. 

The automakers tell a different story, saying mice, rats and squirrels have been chewing through wire insulation long before it was made out of soy. 

Regardless of what the insulation is made of, vehicle owners should make sure rodents aren't chowing down and creating a problem in the engine compartment.  They can have their repair facility check for these signs:  Little bits of acorns, leaves, chewed up plastic and animal droppings in the engine's nooks and crannies.  Using a black light, your technician can detect animal urine, a sure sign that they've been using your engine compartment as a warm apartment, a nest and a dining room. 

You can take steps to prevent rodents from chomping your vehicle's parts.  Honda—one of the vehicle manufacturers that uses soy-based wiring covering—makes a rodent tape.  It contains a spice called capsaicin that rodents find too hot to handle.  Other preventative measures include installing metal mesh around wiring harnesses or spraying the engine compartment with special rodent-repellants. 

Rodent damage can cost one vehicle owner thousands of dollars to fix, not the kind of bite anyone wants taken out of their bank account. 

QUIET TIME (Listening for Vehicle Problems)

Everybody's got friends like this.  You know, the kind who, the minute they get in their vehicle and turn the key, the sound system is deafening.  They just love to hear that music, sports, news… anything but the sound of the vehicle itself.

And maybe you're that person, too.  Here's something to consider: your sound system might be drowning out some valuable clues that could help you diagnose problems with your vehicle, problems that need to be dealt with. So, turn down the volume and listen for these things:

• A clicking sound when you're braking or turning—You could be missing some parts in your braking system, or it could be damaged. That sound could also signal that components are just plain worn out.
• Rattling under the hood—If it sounds like metal clanking against metal, you could have something serious going on, maybe an overheating engine or your timing needs adjusting. That knocking sound could also be as simple as you've been using lower octane gasoline than is recommended for your engine.  Time to get that checked out.
• A squealing or high-pitched sound coming from the engine compartment. Could be a belt is loose, wearing out, dried out or cracked. A pulley might be failing or a bearing might be on its last legs.  Better to have that fixed now than be stranded somewhere later.

Here’s our Triple A Automotive suggestion - set a regular weekly alarm in your smartphone alerting you to listen to your vehicle once a week for five minutes.  Just five minutes without the music or the sports show or public radio… whatever your taste is. You can even use your smartphone to record any noise you might be hearing.  Between that and your description to your service advisor, a Triple A Automotive technician should be able to diagnose the source of the noise and get your vehicle sounding healthy again. Do it before that noise turns into the sound of a serious problem. 

Who knew a little quiet time could be so useful?
