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

It's bad enough when you mistakenly leave a window open in your vehicle on a rainy day and you find your carpet soaked.  But what in the world is going on when your windows are closed tight, not leaking and you STILL wind up with wet carpet? The answer could be something you might not even know your vehicle has. And the answer is? Drains. And those drains can get clogged.  Yes, your vehicle has several drains with tubes or hoses attached to them that you really never see.  There are some in and around the hood that channel rainwater down to the ground.  There are some that take condensation from the air conditioner and allow it to flow outside.  And if your vehicle has a retractable sunroof or moon roof, there are small drains at each corner that connect to tubes that go through the vehicle body down to an exit near the ground.  Considering all the leaves, dirt, dust and other debris your vehicle encounters on a daily basis, it's not surprising that these ... read more

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 servi ... read more

Automotive design has come a long way since the days of the Model T, especially when it comes to safety technology.  You can thank computers for a lot of the latest innovations.  Here are a few that have been making their mark in recent years. Adaptive cruise control.  This is cruise control with a brain.  Not only will adaptive cruise control keep your vehicle going at a steady speed, it will also slow it down and even stop it if the vehicle ahead of you slows down and stops.  Automatic emergency braking.  We've all been distracted while driving, and you've probably been in a situation where the driver ahead of you has suddenly stopped.  Or maybe your attention wandered for a minute and you looked up to see your vehicle closing in fast on the car ahead of you.  (After all, there are a lot more distractions in your vehicle these days.)  New systems that use cameras, lasers and other types of sensors will warn you to start braking.  If y ... read more

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

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

It's pretty frustrating when your driver's window won't work.  You can't get your food at the drive-thru without opening the door, have a tough time using the ATM from your vehicle, can't have that fresh breeze blowing through your hair as you listen to your favorite road tunes. Plus, there's a safety factor.  Your windows provide an escape route in case you need to get out and the doors won't work.  Let's take a look at what's going on when your window won't operate. Most vehicles these days have power windows.  They have an electric motor in each power window and sometimes those fail.  They often give you a warning that they're on their last legs by making a noise or hesitating, so if you get a sign like that, have a technician check it out. Loss of power can also be due to a blown fuse, a bad switch or faulty wiring. All windows have something called a regulator that moves the glass up and down.  They have a lot of moving parts in them which can break ... read more

It's happened to all of us.  We're driving down a highway at night and over a crest appears a car with its high beams blazing.  You are momentarily blinded, hoping the other driver will switch them to their low beam setting and restore your vision. Not only do we not appreciate being blinded, face it; we don’t want to be that other driver, either.  You know, the one who forgets to turn down their high beams. Why do we want high beams in the first place? They can improve safety when used correctly, giving drivers more reaction time since they can see farther down the road.  But research has found many drivers either don't use them or, when they do, they frequently forget to switch to low beams.  Enter the automatic high-beam dimmer. The quest for the perfect one began back in the 1950s, General Motors invented something it called the "Autronic Eye." It was a phototube which sat on the dashboard and turned down your beams when it saw other headlights.  ... read more

It's bad enough in cold weather when ice and snow block your visibility.  Add to that fog on the inside of your windows and you could be driving blind.  So here are a few tips on how to keep your windows from fogging up when there's a chill in the air. You probably know fog is really condensation, when moist, warm air meets a cold surface and turns to liquid.  If your windshield fogs up, you probably turn on your windshield defroster. Most defrosters blow heated air on the windshield glass to warm it up so it won't condense the moisture.  Many also turn on the air conditioning to reduce the moisture.  That same strategy can work on the rest of the windows.  First, turn up your heater's temperature setting.  The hotter the air, the more moisture it will hold.  Also, turn off the "recirculating" setting since you want all outside air to come in. Then switch on the air conditioning.  It will remove the moisture from the outside  air that i ... read more

Cold weather can present some real challenges when it comes to your vehicle's windshield.  Think of it.  Your windshield is your window to the world when you're driving, and clear visibility is extraordinarily important for safe travels. So here are 3 tips to ensure that your windshield can do its job during the cold weather. Don't ever pour hot water on a frozen windshield.  Let's say you head outside and see your vehicle covered with ice. You think, hey, maybe I can heat up a pot of water on the stove and melt that off fast.  Don't do it!  You run the risk of shattering the glass the second that hot water hits the frigid glass.  Ditto for using a propane torch.  Glass does not do well with sudden temperature changes.  Instead, turn on your engine and start the defroster, which heats the windshield up gradually.  Use a plastic scraper designed for windshields (don't EVER use metal to scrape) and be patient.  Don't hammer on the ice to ... read more
