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.

A Hot Mess (AC System-Compresser)

Air conditioning used to be a real luxury in a vehicle, but now it's standard in most.  Your vehicle's air conditioning system is built to last a pretty long time, but like anything mechanical, sometimes it fails. 

It helps to know a little about how the A/C works. There's a compressor that pressurizes the refrigerant (you probably recognize the term Freon).  That makes it hotter, so it then goes through a condenser that cools it off.  Then another component takes out impurities and humidity before the Freon goes to a device that makes it lose pressure before it goes to the evaporator.  That's where it gets colder and takes the humidity out of the air. Then your vehicle's ventilation system blows air over the evaporator, cooling the cabin air that gives you such relief on a hot day.

Of all these parts, one that does a lot of work is the compressor.  It has to compress that refrigerant and circulate it through the system.  It turns on and off several times when it's working. The good news is that if it's going to fail, it sometimes lets you know. 

One of the signs that your air conditioning compressor is going bad is a noise under the hood when the engine is on, sometimes a squealing or grinding sound. It usually is pretty noticeable. Compressors have a bearing that can seize up after time, causing the belt that drives it to squeal when it's trying to turn something that won't turn.  It will sometimes cause that belt to break. 

Your service advisor can tell you if your compressor is repairable or must be replaced.  In the case of a broken belt (often a serpentine belt that drives several components) the belt will have to be replaced as well.

The compressor also has a clutch that turns the compressor on and off so it doesn't have to run all the time. Sometimes that clutch can fail, too, and your service advisor will often recommend you replace the compressor and the clutch at the same time. Our technicians can help make sure your air conditioning system keeps its cool, and you along with it.

Don't Be Shocked (Shock Absorbers)

If you've ever ridden down a rough road on your bicycle, you know how hard a ride it can be.  Yet drive down the same road in your car, truck or SUV and it miraculously will smooth out the ride.  That's because it is equipped with shock absorbers.  They are built to dampen impacts from road irregularities.  But after taking hundreds of hits from potholes, railroad tracks and curbs, your shock absorbers can wear out.  Besides the rough ride that can cause, there are other ways your vehicle's performance can be affected.

When it comes to braking for example, you may take a longer distance to stop.  That's because shocks help keep your tires in contact with the surface of the road.  If the shocks aren't working properly, the tires won't make contact like they should.  So when you slam on the brakes, your vehicle will take longer to stop.

Consider what worn out shocks are doing to your tires.  Since the bumps aren't being dampened as much, your tires can bounce up and down more.  That can produce a problem of uneven wear called cupping.

And when you start out from a stop, your vehicle may not have the traction it should since the shocks aren't keeping them down on the road as you accelerate.  If you have front wheel drive, you may lose some steering control on acceleration. Obviously, many of these things involve safety concerns.

Pay attention to any deterioration in your vehicle's ride quality.  If your vehicle is starting to bounce up and down and its ride feels bumpier than before, head on over to your vehicle service facility and get your suspension checked out.  Do the same if steering response isn't as good as it used to be.  Notice that your vehicle nose dives when you brake?  Are your tires wearing in an unusual manner? All are signs that your shocks may be on their last legs.

If the last time you replaced your shocks was 50,000 miles/80,000 kilometers ago, a technician should evaluate them.  Don't be "shocked" if it's time for new ones.

Command Performance (Engine Air Filter)

The internal combustion engine in your vehicle counts on two things that mix together to be burned in the engine for power: fuel and air.  Both are important, of course.  If you run out of fuel, your engine won’t run at all.  Since there’s plenty of air around, you won’t run out of air, but you could feel your vehicle’s performance suffer if the engine air filter starts to get clogged. 

It's important that the air that enters your engine be free of dirt, dust, and debris to prevent damage to internal components.  That’s where the engine air filter comes in.  It prevents those particles from entering the engine, an important job that most people just take for granted.

After a while, your air filter will get dirty, which results in less air reaching the engine.  Modern fuel injected engines can adjust the amount of gas to mix with the air that is getting in, so your fuel economy won’t change significantly.  What will change is how well the engine performs, its acceleration.  In one test, a US Department of Energy study showed that a dirty air filter reduced a vehicle’s get-up-and-go by as much as 11 percent.  

The company that made your vehicle includes guidelines in your owner’s manual on how frequently that filter should be changed, and doing so will maintain your engine’s performance. If you drive in dusty, dirty areas or those with a lot of industrial pollution, we recommend you replace the engine air filter more frequently than the manufacturer’s recommendations.  

When you bring your vehicle to us for regular maintenance, we will routinely check several components, including your engine air filter, and recommend a change when we see signs it’s needed. It’s good for your engine, and you’ll enjoy the performance you expect.

Don't Miss a Beat (Importance of Regular Maintenance)

In many places, license plates have to be renewed every year or else you can't drive your vehicle legally.  Usually, you'll get a reminder from the agency that issues the plates.

That kind of regular attention needs to be paid to your vehicle as well.  Its manufacturer has determined a schedule of service items that need to be done regularly, just like renewing your plates.

Some depend on time, others depend on distance.  A perfect example is oil changes.  It's the most important scheduled maintenance you can have done to give your engine its longest life possible.  The manufacturer recommends the oil filter be changed at the same time.

Here are some more items.  Your engine air filter gets dirty and needs adequate air to run most efficiently.  The manufacturer recommends an interval for replacing that.  Also tires, brake pads, timing belt, oxygen sensor and other items require regular replacement. 

This is one of the reasons to find a service facility that you like and keep going there.  Many will keep records of what's been done to your vehicle and send you reminders of when it's time to schedule service items.  Some do it by mail, others by email.  Still others might text you or give you a phone call.  Remember, they base those reminders on the vehicle manufacturer's recommendations. 

We all have a lot going on in our lives, so these reminders can help you avoid missing important service items that are important to your vehicle's durability and safety.  So if you move or change phone numbers or email addresses, make sure your vehicle service facility gets the word.  Otherwise you won't get the reminders and your service advisor will wonder what's happened to you!

At the same time, you might want to let your vehicle manufacturer know when you've changed your address, phone number or email address.  If there is a safety recall or your manufacturer is offering an extended warranty on some of your vehicle's systems, they'll need to reach you.
