Alternator Facts (Failing Alternator)

If you notice that your headlights are flickering at night, that's something to pay attention to. While there could be many different things that could cause that problem, one possibility is your vehicle's alternator.

The alternator takes mechanical energy from the engine and turns it into electricity, in essence a generator.  The current it makes charges the battery and supplies power to the vehicle's electrical systems.  An alternator is made up of several different parts: a pulley, magnets, coil wires, brushes and a voltage regulator.  While your vehicle is running, these parts get a good workout and, after time, they begin to wear out.

Other symptoms of a failing alternator include your vehicle's lights dimming, the power windows going up and down more slowly than they used to, your power seats not moving quite as fast as before. 

Another sign of a worn out alternator is engine stalling.  Vehicles with fuel injection require a certain amount of power, and when an alternator is going bad, your engine could stall because the alternator isn't cranking out enough of it.

An alternator on its last legs can also fail to charge your battery properly.  Sometimes your battery isn't getting enough charge from the alternator and will go dead.  It also can be the opposite problem. The battery is getting too much power and will cause the battery to get hot.  Your vehicle may give you a clue on the instrument panel.  If you see any of these warning lights, take note: Check Engine, ALT, CHARGE or one that looks like a picture of a battery.  If that light is on, it's time to have your service facility give it a look.

As mentioned earlier, there are other components of your vehicle's electrical system that can fail, such as a worn out serpentine belt or a malfunctioning voltage regulator.  A reputable service facility has diagnostic tools to pinpoint the causes of your problems. And when your issues are fixed, your electrical system will be back to its hard-working self.  You'll get a real charge out of it!

Free Money (Almost) (Fuel Saving Tips)

You spend a lot of money on a vehicle, probably the most money you'll spend on anything except a house.  But the spending doesn't stop after you've bought it.  It goes into things like insurance, repairs and fuel.  One good piece of news is that you can cut down the amount you spend on fuel if you follow a few tips.

Keep your speed under 50 mph/80 kph.  Anything over that and your fuel economy will go down quickly the faster you go.  Sure, you can legally drive  faster than that, but practice this one tip and it can save you from 7%-14% on fuel.

Use cruise control.  The steady speed increases fuel economy by avoiding unnecessary braking and accelerating. 

If your vehicle is carrying unnecessary weight, unload it.  If you can save 100 pounds/45 kilograms, it can save you 1% of your fuel. 

Don't idle.  Let's say you're sitting in a parking lot with your engine running for 10 seconds.  Any more and you're wasting fuel.  Turn off your engine and start it when you have to get going.  You may have noticed that many newer vehicles automatically turn the engine off when the vehicle stops.

Avoid using a roof rack.  A cargo box strapped on the top of your vehicle can reduce your fuel economy by 2%-8% in city driving, by 6%-17% on the highway and by 10%-25% at highway speeds over 65 mph/105 mph.

Also, if you have roof rails on your vehicle with crossbars, you can save 1% of fuel simply by storing them somewhere else.  Some vehicles like Chrysler's Pacifica minivan allow you to store the crossbars inside the roof rails to reduce drag.

Keep tires at their recommended inflation.  It can save you 3% of your fuel bill.

Use the right motor oil for your vehicle.  Using the wrong kind can cost you 1%-2% more money on fuel.

Sure, many of those savings are small on their own.  But add them up and you'd be surprised at how much you can save.  Also, keep in mind that a well maintained vehicle will also save you fuel, so make regular maintenance trips to your vehicle service facility.

Clean Slate (Protecting Vehicle's Finish)

Winter is one of the hardest times to keep your vehicle clean. But did you know neglecting to wash your vehicle in winter could cost you a significant amount of money in the long run? Here's why.

Many areas deal with snow and ice in the winter, and the salt and sand that are used to keep the road surfaces from being slick are also super corrosive to a vehicle's metal body and undercarriage.  That includes all the parts underneath that can be splashed with brine, saltwater and other road debris.  Winter is also tough on vehicles where there isn’t snow, sometimes from ocean salt or winter's extra humidity and rain. 

If you have any breaks in your vehicle's paint, whether it be from a little fender bender or a stone chip, that corrosive winter moisture can get through those cracks and start eating away at the metal underneath. 

If you can, you should get any dents or damage fixed as soon as possible so your vehicle has a protective layer of paint between road chemicals and the metal.  You may want to wait until the warmer weather, but while you're waiting, the damage is getting worse.  If you're not sure of a reputable body repair shop, check with the service advisor where you have mechanical work done.  They're usually knowledgeable about who is good and not so good. 

You also may be tempted to skip the car wash during the winter since your vehicle is just going to get dirty fast anyway.  You may want to reconsider.  Many winter road treatments now use brine that gets in every nook and cranny of your vehicle.  It's wise to clean that off regularly during the winter, and many washing facilities include a spray underneath that gets rid of that salt.  Your vehicle repair facility may even have its own car wash, a nice bonus when you take your vehicle in for repair or regular maintenance.

Ready, Set, COLD! (Getting Vehicle Ready for Winter)

When the temperatures plunge, your vehicle better be ready because it faces a whole new set of challenges.  Rubber stiffens, glass fogs, fluids freeze.  Just thinking about it can get your heart beating faster.  So here are some tips for getting ready for those inevitable colder temperatures.

Make sure your tires are in good shape and properly inflated.  Traction can be less than ideal on slippery streets, so your tires must have enough tread to grip the road.  They should also be inflated properly, and inflation will change as the temperatures go down. One last thing on tires. Do you know how old yours are? They actually have a birthdate printed on them.  Old rubber can compromise drivability and handling.  Some tires look great but their rubber doesn't handle stresses like it used to.  Have your vehicle service facility inspect all of these aspects of your tires so you are riding on tires that are fit to go.

Anyone who lives in an area where the temperatures get down to freezing knows frigid mornings can reveal an unhealthy battery at the most inopportune time.  Age also counts when it comes to batteries, so you should know how old and healthy yours is.  Special equipment at your service facility can let you know how much more life you can expect out of that battery.  It's obviously better to have it replaced before rather than after it fails.

You have to see out your windows and windshield in order to drive safely, so now's the time to have your heater and defroster checked out to make sure they can do their jobs.  A few tweaks here and there can make a big difference before you find yourself shivering and fogged up.

And finally, make sure you have some vital emergency supplies.  Yes, a blanket can save your life if you are stranded in cold weather.  A small shovel can help you dig out of a slippery spot.  And your survival may depend on having a little extra food and water on hand, so keep a little supply of bottled water and power bars stored away. Doesn't hurt to have an extra cell phone charger in your vehicle, either.

You may have heard all of this before.  Well, trouble happens when you least expect it. Taking a few minutes now can make a huge difference when it rears its ugly head later.
