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 top shape, disconnecting the cables, inspecting them and cleaning their ends and the battery terminals.  Cables, by the way, are often made up of smaller strands of wire.  If they are frayed, some of those smaller wires can touch metal parts of the vehicles that they shouldn't.  The result? Electrical system malfunctions.

So if you see any of these signs that something is not quite right with the power in your vehicle, consult your service advisor and get it checked out.  Feel the power!

How Tired Are Your Tires? (Tire replacement)

Of the things you think about most, your tires are probably pretty far down the list. That’s understandable because today’s tires are engineered to do their job without needing you to pay too much attention to them. But they DO wear out, and worn tires can contribute to skidding in bad weather, not being able to stop, a ride full of uncomfortable vibrations and, even a sudden blowout. Yikes. Let’s figure out right now how to know if your tires need replacing!

Let’s face it. Most of us don’t know the first thing about tires. So, the best way to make sure what shape yours are in is to take your vehicle to a qualified service facility to have the tires checked out by a trained technician.  Here are things they’ll check:

• Tread.  Tread is the part of the tire that touches the road surface.  Different tires have different tread patterns and something called tread blocks - the raised rubber parts that contact the road. The longer a tire has been on a vehicle, the more of that rubber wears off.  The technician will check to see if there’s enough of that tread left on your tire for sufficient traction to accelerate, steer, and brake.
• Pressure. It’s important your tires be inflated properly so your tires will perform the way they’re designed while driving.  If your tires have low air pressure, the technician will check to see why, perhaps cracks in the sidewall from age, a nail in the rubber picked up on the road, or bulges. It’s also important your tires are not overinflated too.
• Wear.  Your tires should wear evenly.  If they haven’t, the uneven wear can cause vibrations that you can feel in the steering wheel.  Maybe the whole vehicle shakes at a certain speed.  Your vehicle may require other services such as balancing, alignment, or suspension repairs to prevent future tire damage.
• Age.  Your tires may have adequate tread, but if they’re too old, it’s time for new. Rubber gets old, and when it does, it loses its elasticity.  Ever find an old rubber band and tried to stretch it? It’s brittle and will break easily. Hotter climates will age rubber—and tires—faster. All tires have their date of manufacture stamped on them, so your service adviser will be able to see when your tires were made.

If it’s time to replace your tires, you’ll find you have many choices for new ones: different brands, models, designs, etc.  Your service adviser can help you figure out which ones are right for you. It’s much better—and safer—to do it before one of them fails at the least opportune time.

Passing the Test (How to Prevent Emissions Test Failure)

Vehicle emission testing has become ubiquitous in North America and for a good reason.  Clean air quality is important for the environment and all of us.  Since vehicle emissions are among the main causes of air pollution, emission testing can alert you to problems in your vehicle than can be fixed so it won't needlessly pollute.

Emissions tests are looking for certain toxic gases internal combustion engines produce, such as nitrogen oxide, particulate matter, non-methane organic gases and formaldehyde.  Emissions control systems reduce these gases if they are working properly. 

The best way to minimize pollution is to keep those vehicle systems working properly, and periodic inspection and maintenance is the key.  So if you want to make sure your vehicle will pass an emissions test, it helps to know what might go wrong.

Let's start on the easy one.  Your gas cap could be loose, allowing vapors to escape into the atmosphere.  The most common solution is to replace it.  Or your air filter may be dirty.  A dirty air filter may push your hydrocarbons pass the acceptable level.

Now to the more complicated things.  The mixture of fuel and air in your engine may be tilted toward the "too much fuel" side.  That could cause problems for your vehicle's catalytic converter, a device that converts toxic gases from your exhaust into less toxic pollutants.

Your vehicle has a closed system that prevents fuel tank vapors from escaping into the air; it's called the EVAP system.  A technician can track down problems.

Vehicle engineers have gone to great lengths to minimize the amount of pollution your vehicle produces.  Your vehicle's manufacturer recommends how frequently those systems need servicing.  Keep those systems in good shape and you're likely to pass emissions tests with flying colors.  Neglect them and you might find your vehicle failing an emissions test.  When that happens, you'll have to get the problems repaired before you can get back on the road.

Bad Vibes (Disc brake rotor problems)

If you were to name the most important safety feature on your vehicle right now, what would your answer be? A lot of driving experts would agree that it’s your brakes.  Most newer vehicles use a well-engineered and efficient style of brakes called disc brakes. 

The name disc brakes comes from one of the components: a disc attached to the wheel hub that is squeezed by parts called calipers.  If you’ve ever ridden a bicycle with hand brakes, you probably have seen how they squeeze against the rim of the bike wheel to stop the bike. It’s similar to the way your vehicle’s calipers squeeze against the disc rotor, with added parts called brake pads attached to the calipers that are what create the friction and stop your vehicle.

Here’s why disc brakes need regular maintenance.  Over time, that friction creates wear and tear on the brake pads and the rotors, and you’ll start to see the signs.  Your brakes may have one of the 3 “S” sounds: squeaking, squealing, or scraping. The sound is usually the first sign of brake pad wear which can lead to rotor damage.  Soon you may notice a pulsating or vibration when you brake. That’s because your once smooth and straight rotor disc is warping from the heat generated from friction. Or it may be due to wear.  Eventually, your brakes will take a longer distance to stop your vehicle, and the rotors can have grooves carved into them.

When you start noticing any of these signs, it’s a good idea to have them inspected by a trained technician.  They will measure the rotor thickness, check wear patterns for grooves and heat discoloration, and see how much of the brake pads remain. They will also check to make sure all brake components are moving freely, check your brake fluid, and look for corrosion.

Most vehicle manufacturers require worn or damaged rotors to be replaced, not resurfaced. It’s all part of a complete brake job, replacing pads and the brake hardware parts along with the rotors. It reduces the chance of premature failure.

How often you will need your brakes serviced depends on the manufacturer’s recommendations, your driving habits, and the environment you live in.  Your service facility can recommend the best replacement parts based on those factors. 

Regular maintenance and attention are vital for keeping your brakes performing like they are designed to. Remember, your brakes are your vehicle’s most important safety feature.
