Slipping into Fall (Driving with ABS Brakes)

As the weather changes over from hot to colder, drivers will have to deal with more slippery streets.  And it's important to know how to drive with the brakes you have on your vehicle.  In the 1970s, anti-lock braking systems (ABS) started to be installed on vehicles and they've been a game changer for drivers.  Most modern vehicles have ABS and it's important to know how to drive with them. In older vehicles without ABS, the driver applies the brakes by pushing down the pedal.  That, in turn, sends braking pressure to all four wheels at once.  But all four tires don't have the same traction because the road surface they're each on isn't exactly the same. ABS allows sensors to determine when particular wheels are slowing down more quickly.  The ABS then reduces braking pressure to the wheels that are about to lock up.  That way the wheel turns and the tires keep some grip. (You have to have grip to stop.) It's kind of what drivers try to achieve when ... read more

Cruisin' on Down Main Street

When automakers first came out with cruise control, it was a real luxury item.  The older cruise controls used a mechanical vacuum system but it worked.  Well, some of the time.  Now days, cruise control is all electronic, thanks to computers.  It's reliable and a real convenience on long trips.  Cruise control is offered on most vehicles and standard on a lot of them.  Because it's electronic, when it breaks, it's usually some electronic component.  Your vehicle's cruise can be the victim of a blown fuse. Or your vehicle's speed sensor, which—not surprisingly—measures your vehicle's speed, can also stop working.  And that will cause your cruise to stop cruising.  Vehicles with cruise control also have a built-in feature that, when the brakes are applied, turns off the cruise.  With electronic cruise control, that happens thanks to the brake pedal switch, and if a problem develops in that switch, the cruise might not work.

The John's Automotive Care Guide to Saving Fuel: Beware of Myths

There's a lot of auto advice in CA right now on how to save money on gas. Some of it is good advice. Some of it isn't. Some of it is myth. And it may well be a scam. Plain and simple. When someone offers you a product designed to save money on gas, ask yourself, “Does this sound too good to be true?” If the answer is yes, do more research.The internet offers us a convenient and quick way to research someone's claims about gas savings. San Diego drivers can usually find out in only minutes whether that claim is questionable or not.Chances are other San Diego drivers have already tried what you're being offered. If you find evidence that others feel they have been scammed, you should be wary of becoming the next victim. There aren't any pills, magic or otherwise, that you can drop into your gas tank to improve your gas mileage. Drop in enough of those pills and you can actually harm your vehicle. The last thing you need is a bunch m ... read more

A Turn for the Worse (Using Turn Signals)

Distracted driving is bad, you know that.  Daydreaming, talking on the cell phone, putting your makeup on in the rear view mirror.  All bad.  But there's something else that causes more than twice as many accidents, according to a recent study.  And that's people who don't use their turn signals.  Maybe you're one of them.  One survey said nearly a quarter of drivers were just too lazy to use their turn signals.  Others said they didn't use them because they weren't really necessary.  Traffic laws may dictate otherwise, but statistics show police don't write that many tickets for turn signal violations.  You may have encountered the driver who cuts into your lane without signaling a change.  Often, that person does it deliberately to catch you off guard so you won't invade his or her space.  And when it comes to young drivers using turn signals, one insurance company survey showed more than two-thirds of those they talked to admitt ... read more

Light Up your Life (Headlamp Replacement)

Did you know that having a burned out headlight can result in your rearview mirror reflecting some flashing lights? In other words, you might get pulled over by the police for only having one working headlight, because in most places it's against the law.  Not only is it illegal to drive with one headlight burned out, but it's also dangerous. You can't see down the road nearly as well at night with only one headlight, and other drivers can't see you as easily either. The good news is many newer vehicles warn you when one of your headlamps burns out. When that happens, have it taken care of as soon as you can.  While there was a time when all headlamps were pretty much the same, the same isn't true these days. There are halogen, Xenon, LED and other technologies used in modern vehicles.  Plus there are sealed beams (like those on older vehicles) and capsules. If you have a burned out headlamp, ask your service advisor for recommendations.  Usually when one side goes ... read more

Got it Covered! (Timing Cover Maintenance)

You may have heard at one time or another about something called a timing belt or timing chain in your engine.  And you may know that if they fail… well, let's just say that there can be some major engine damage.  So obviously, we want our timing belts and chains to be in tip-top shape. One part that helps keep them running the way they should is the timing cover.  As you can probably guess, it's something that covers the belt or chain.  The timing cover protects both belts and chains from dirt and road debris.  Timing belts also need to be lubricated so their covers allow them to be lubricated as well.  They have a gasket that insures a good seal for the engine.  If that gasket breaks or develops a leak, then engine oil can escape, and loss of lubrication is never good for an engine component. Other symptoms of a failed timing cover are leaking coolant, a metallic sound coming from the front of your engine or your Check Engine light coming on ... read more

Differential Service

When you're driving and turn a corner, you probably aren't aware of all that's going on with your wheels.  The outside wheels have a longer distance to travel than the inside wheels, so there are gears that allow the wheels to go at different speeds when you turn.  That set of gears is called a differential.  In front-wheel drive vehicles, it's by the transmission and called a transaxle.  Rear-wheel drive vehicles have the differential, naturally, on the rear axle. Many all-wheel and four-wheel drives add a center differential since power has to go to the front and rear wheels. (Some newer vehicles power wheels with electric motors, but that's a whole different story.) Time and distance traveled eventually can take their toll on the differential, and you may notice some noises you hadn't heard when your vehicle was newer.  Sometimes you'll hear a whir that might change in pitch when you turn.  You may hear clicking sounds when you're moving.  Others d ... read more

More than Pads and Rotors (Brake Caliper Replacement)

You might be familiar with brake pads and rotors, two components of your vehicle's brakes that have to be regularly serviced.  Here's another important component of your brakes: the calipers. Calipers are used in disc brakes, the type of brakes now found in most recently manufactured vehicles.  A caliper is the part of the brakes that squeezes the brake pads against the discs, or rotors, which turn with your wheels.  There are different kinds of calipers, but the basic principle is the same.  You press down the pedal, brake fluid activates a piston or pistons that squeeze the brake pads against the disc and the friction slows down your vehicle. While modern vehicles have a warning system to let you know it's time to get your brakes checked, your brake light usually goes on when your fluid level is low or your fluid pressure is low.  But you may have to look out for signals your calipers are the problem.  If your vehicle pulls to one side when you brake, th ... read more

Fears and Gears (Signs of Automatic Transmission Problems)

Automatic transmissions rule. The old days of shifting your own gears are a thing of the past for most drivers.  But automatic transmission trouble can be a big inconvenience for any driver if it comes at the wrong time in the wrong place.  Here are some signs to look out for that may mean you are having transmission issues. When you are driving, your vehicle seems to slip in an out of gear without you touching anything.  That's what some call, not surprisingly, a "slipping transmission."  When your vehicle shifts from one gear to the next, you hear a loud "clunk." Transmissions are supposed to be nearly silent when they shift, so that noise is telling you something is wrong.  If you notice there's a puddle of some fluid under your vehicle, your transmission could be leaking fluid.  Try to figure out what color it is (try putting a piece of cardboard underneath to capture some of the fluid).  If it is red or brown, that's a sign it could be transmissi ... read more

H20 No! (Driving Through Standing Water)

In a year marked by unusually heavy flooding in North America, drivers are very aware of the possibility they may find themselves driving where water has come over the road.  It can be a daunting and frightening situation.  Flooding waters can move quickly and unpredictably, so you have to keep your wits about you when you encounter that situation. Here a sample of one vehicle manufacturer's guidelines on what to do.  First, the vehicle is designed to go through some water, but you must be careful.  Never attempt to drive through water deeper than the bottom of your tires. You can get out of your vehicle to check the depth of the water, but you can never be sure that you aren't going to drive into a spot where the road has washed away.  You can't see below the surface of the water, and suddenly you could find yourself in a place where the road drops off unexpectedly.  In swift moving storm runoff, your vehicle could literally be floating away with the curr ... read more
