Your Vehicle's Other Power Plant (Alternator Replacement)

Your vehicle's engine is probably the first thing that comes to mind when you think of a power plant.  But it has another power source that is vital as well: the alternator.

The alternator is what puts out the electricity that powers such things as your lights, power windows, sound system, and navigation.  Maybe you've started seeing those electrical components behaving in strange ways.  Maybe your power windows are going up and down a little bit more slowly than they used to.  Or perhaps your engine doesn't start as easily or is misfiring.  

Other signs of a failing alternator are headlights that are either brighter or dimmer than usual.  If your battery keeps going dead, it could be that the alternator isn't recharging it.  

The alternator has to get its power from somewhere, and in vehicles with internal combustion engines, that power comes from a drive belt powered by the engine.  Sometimes that belt can fail.  If you hear a whining sound, it could mean bearings in the alternator aren't turning as freely as they used to. You could even notice a burning smell.  Oh, and when you see your battery light illuminated on your dash (it looks like a rectangle with a - and + inside), it may be warning you that your alternator is not healthy.

Bring your vehicle in to us for a diagnosis if you notice any of these symptoms.  If your alternator is bad, we can recommend a new or remanufactured one to replace it.  Some new alternators are warranted for life and remanufactured units usually are guaranteed as well.  

It's important to your vehicle's health to have its alternator putting out the right power consistently.  It may not be as well known as the other power plant under the hood, but it's a vital part of helping your vehicle run the way it is designed to.

Lubricate Driveshaft

See if any of these are happening to your vehicle.  You feel it vibrating excessively underneath when it’s running, or you hear strange clunking, grating, or grinding sounds coming from beneath.  Maybe it’s hard to turn your vehicle, or you can hear squeaking when you’re going slow.  Perhaps you feel a shudder when you step on the throttle.  

Any of those could be signs that your vehicle’s driveshaft might need lubricating, and it’s important to have one of our technicians check it out. Your vehicle’s engine puts out a lot of twisting power.  That force is called torque, and the driveshaft is the part that handles the job of transferring all that torque from your engine to the wheels.  If it’s a four-wheel or all-wheel drive vehicle, it will have driveshafts front and rear. 

Some driveshafts have different segments which are connected by couplings called U-Joints.   So that everything can glide along fine, that whole assembly needs to stay well lubricated.  Our technician can inspect the driveshaft and U-joints to make sure there aren’t any broken or excessively worn parts.  

Many manufacturers recommend servicing and lubricating the driveshaft at certain intervals, and it’s important to keep on that schedule.  It’s essential because poor lubrication can lead to a failure while you are driving, possibly causing other expensive parts to fail.  Not keeping your driveshaft lubricated or failing to maintain it regularly is the top cause of driveshaft problems.

When it Comes to Air Filters, Change is Good (Clogged Air Filter)

Engine air filters may not seem like a big deal, but when they’re clogged up with dirt, dust, and insects, your engine could wind up choking for air and not delivering you the power and performance it was designed to give.

There are actually a couple of air filters in your vehicle.  One filters the air going into the cabin (the cabin air filter), and the other filters air going into the engine.  That engine filter is the one we’re talking about. After several months and long distances traveled, your engine air filter accumulates the junk it’s preventing from getting into your engine. You may notice your engine misfiring, your acceleration may not be what it used to be, it may make strange noises, and the Check Engine light may come on.

When you notice any of those signs, it’s time to bring in your vehicle to have us figure out what’s going on. We’ll visually inspect your air filter.  Keep in mind that your vehicle’s manufacturer recommends a replacement interval for your make and model.  Typically, many automakers suggest replacing the air filter every 10,000-15,000 miles/16,000-24,000 km.  But if you drive in areas that are dirty and dusty, you should have it checked more frequently.  Also, if you spend a lot of your driving hours in congested urban areas, stop-and-go driving can also tax your engine air filter.

When replacing it, it’s important to get the correct filter. Automakers often offer a variety of engines in the same model, so our technician will make sure you’re getting the one that’s made for your vehicle’s configuration.  Keep in mind that the air filter is protecting your engine from contaminants, and having one that properly fits is important with today’s modern, high-tech engines.  

Replacing your engine air filter can help prolong the life of your engine. You’ll both breathe better.

It's (Not) Complicated (Engine Air Filter)

While many components of your vehicle are complex and composed of lots of mechanical and electrical parts, there's one that isn't complicated but still important.  It's your engine air filter.

(And, we should point out, the engine air filter isn't to be confused with the cabin air filter.  The cabin air filter cleans air that goes into the passenger compartment while the engine air filter cleans air that goes into the engine itself.)

Why does your engine need a filter? Think of all the stuff–dirt, dust, and debris in the air¬–that gets kicked up on the road.  If that were to go unfiltered into your engine, it could damage other components.

There are many different materials used in an engine air filter, including paper, cloth (frequently cotton), and other synthetic fabrics.  The material is usually folded tightly to maximize the filtering capability over a relatively small surface.  

Before computers were employed to determine the proper mix of air and gasoline, a dirty air filter could contribute to a decline in fuel economy.  But a study of engine air filters done by the U.S. Department of Energy in 2009 found that in modern fuel-injected engines, computers can maintain the correct air/fuel mix even when an engine air filter is really dirty, minimizing effects on fuel economy.

That same clogged air filter, though, can affect your vehicle's performance, mainly how much power and acceleration it delivers.  In testing three different vehicles, a dirty air filter made the vehicles slower by about 6-12%.  That's something you'd definitely notice if you were driving.

But it happens slowly, over the course of several months, so you might not even know your engine air filter is dirty unless you bring it to us and have a technician inspect yours.  

There are many different types of engine air filters, from the ones made by the original vehicle manufacturer to aftermarket ones.  Some can increase your engine's performance; some can be washed and re-used but are generally more expensive.

Your service advisor can recommend several options for you, depending on the type of vehicle you drive and your driving habits.  Dirty, dusty roads will require more frequent engine air filter changes than cleaner drive routes, and each vehicle manufacturer recommends when your filter should be changed.  Keeping it clean will help your engine breathe a little bit easier.
