Follow the Bouncing Vehicle (Bad Struts and Shocks)

If you hit a bump in the road and your vehicle just keeps bouncing up and down for a lot longer time than it used to, you may have bad struts and shocks.  They're the things that help to keep your vehicle's wheels and tires planted to the road surface. But they don't last forever.  With care and depending on where and how you drive, shocks and struts should be replaced at intervals ranging from 50,000 miles/80,000 km to 100,000 miles/160,000 km.  If you drive on bumpy roads with a lot of potholes, that interval will likely be shorter. Rough surfaces can take their toll. But how do you know if your shocks and struts are doing their job properly? The best way is to have your vehicle checked by a technician.  He or she can inspect the shock absorbers and struts for leaks, corrosion and damage.  Mounts and bushings can also go bad and they should be evaluated as well.  A thorough examination by a technician will also include looking at other suspension parts ... read more

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 ... read more

Tacky or Techie? The Tachometer.

There's a gauge that many vehicles have that says RPM on it.  And there are a lot of people who either don't pay any attention to it or don't even know what it is. Here's why it's a good gauge to know about. It's called a tachometer, and that "RPM" label means it is measuring how many revolutions per minute (RPM) the engine is turning.  Automotive experts know that a vehicle's engine can be damaged if it turns too fast (revving too high) or too slowly ("lugging" the engine). A tachometer (sometimes called a tach) is almost a "must-have" gauge for vehicles with a manual transmission; the driver has to manually change gears; the tach helps the driver know when revolutions are in the optimal range. Some say you don't need a tachometer if you drive a vehicle with an automatic transmission. It's true that most drivers of automatics don't even look at it.  But there are times when paying attention to the tach can help you prevent an expensive repair. Here's a good example.&nbs ... read more

No Yolk! Rotten Egg Smell (Sulfur Smell Causes)

The pungent smell of rotten eggs can send people running for the hills.  So when that odor is inside your vehicle, yikes!  Yolks!  The good news is that a trained service technician can search the source of that smell and stanch the stench… that comes from another words that begins with S.  Sulfur. Fuel contains small amounts of hydrogen sulfide, but they're enough to stink up a vehicle when it's not properly burned.  You may know that the smell of rotten eggs can often be a sign of a catalytic converter that isn't working the way it should.  That could be due to age, damage or an abundance of oil that's clogging it up.  If a sensor in charge of managing the fuel has failed, the engine can run with too rich of a fuel mixture.  That can overload the catalytic converter and allow some of the byproducts to escape without interruption from the chemical reaction that is supposed to prevent them from going out the tailpipe. There's another possi ... read more

Too Hot to Handle (Vehicle Overheating)

In the hot weather, seeing steam coming from the engine compartment is something we all dread.  No one wants that to happen to them. But if you know the signs of overheating and how to deal with it, you may be able to reduce the risk of damage to your vehicle, maybe even prevent getting stranded on the road. Besides the steam coming out of the engine compartment, here are a few signs of overheating.  Your vehicle has a heat gauge that may have a needle that can go into a red zone or up to the "H" (for High) position.  You may smell odors, perhaps a burning (could be hot oil) or a sweet smell (engine coolant leaking).  When you encounter any of those signs, you know you have to do something to keep the engine as cool as possible to avoid potentially catastrophic damage.  Turn off the air conditioning and turn up the heat.  While that last part may sound odd, it helps draw heat out of the engine.  If you can do it safely, pull off the road to a spot awa ... read more

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 octan ... 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

The Cable Guy (Battery Cables and Maintenance)

If you've ever noticed your vehicle's lights are dim or not working at all, the problem could be many things.  But one possibility is your battery cables aren't doing their job.  A power outage in your vehicle is similar to one in your house and needs to be repaired to get things back to normal. Battery cables connect your vehicle's battery to the vehicle itself.  There is a positive cable when provides the power and a negative cable that connects to the vehicle chassis and provides a ground for electrical components.  A failing battery cable may cause your vehicle not to start.  Your starter may turn over very slowly.  Or you may just hear a series of clicks.  One other clue is on your dash—the battery warning light.  There are many things that can cause power issues in a vehicle, but it's important to keep battery cables clean and maintained.  Salt and corrosion are enemies to any power system.  A technician can keep things in t ... read more

Don't Do It Yourself (Perils of DIY Vehicle Repair)

Your vehicle is a complicated machine, and yes, it would be nice if you could take care of all of its problems yourself.  There was a time when vehicles were simpler and it wasn't too hard for a weekend mechanic to replace brakes, adjust a carburetor or perform a tune-up.  But vehicles are far more complicated these days, with traction and stability control, anti-lock brakes, air bags and fuel injection just a small sample of the new technologies.  Like a lot of things these days, technology changes in leaps and bounds.  Anyone who repairs vehicles has to stay up on the latest computers, sensors, suspensions, steering, electronics, hydraulics and more.  Many power steering, braking and heating and air conditioning systems that used to be mechanical are now being replaced by electronic systems.  Computers are an integral part of  much of the latest automotive technology, something you didn't see a lot of until as recently as the 1990s. Today's most hig ... read more

Gas Smell! (What Causes Gasoline Odors)

If you've ever walked into your garage and noticed it smelled like gasoline, pay attention. Gasoline can be dangerous, both from the health problems fumes can cause and the fire danger gasoline presents.  There are many things that can cause a vehicle to give off a gasoline odor.  One of the easiest to track down is the gas cap.  It could be missing or it doesn't seal well any more (they do wear out).  That can also cause the Check Engine light to light up, so those are clues to tell your service advisor when you take it in for diagnosis. Another thing that can cause the Check Engine light to come on and produce a gasoline smell is the fuel filler neck. It's the part that goes from the place you put your fuel in to the gas tank. Over time, these can wear out and fail (they're made out of rubber or metal).  They can leak gasoline, too. It's always a good idea to check the garage floor for any gasoline puddles.  Note the location of the puddle in relation to ... read more
