Light's Out! Trouble Ahead (Exterior Light Bulb Service)

Whether or not your exterior light bulbs are all working probably is not at the top of your list when you think about your vehicle.  But those exterior lights are more important than you think, and they're vital to your safety and that of other drivers near you.

Headlights are important.  Not only do they help you see safely down the road at night, they also help oncoming drivers know that the vehicle they're approaching is not a motorcycle.  Both headlights should be working properly and aimed so that they don't blind other drivers.

Taillights are also important for a few reasons.  They tell drivers what your intentions are (changing lanes, turning, stopping).  So, the bulbs back there must be all in working order for maximum safety. Ditto for the front turn signal lights.  They alert oncoming drivers to your lane changes or turns (if you use your turn signals!).  Some side mirrors also have turn signal bulbs in them.

There are a few other important bulbs.  You may not care about the ones that illuminate your rear license plate, for example. But they are there to help public safety forces identify your vehicle. In fact, in many municipalities you can be pulled over and ticketed if ANY of the standard lights are burned out.  So not only does having all your exterior lights working improve your vehicle's safety, it may keep you from getting a ticket.

Many newer vehicles have a light on the instrument panel that will go on if on-board computers detect voltage problems in any of your vehicle's bulb circuits.  Sometimes it can be hard to figure out which light may be not be working since there are so many. Sometimes it's simply a matter of replacing a bulb, but it may be an electrical problem causing the problem.  Stay legal and safe by having your service repair facility diagnose and fix a non-working light, a really bright idea, don't you think?

A Non-Starter (Alternator Problems in Cold Weather)

As the temperatures dip, we all know there could be problems starting our vehicles. After all, batteries can grow old and not hold a charge as well as when they were newer. Or starters can go bad.  But there's one more component to keep an especially sharp eye on during winter: your alternator.

The alternator is sort of like a small generator. It sends power out to various parts in your vehicle that need electricity.  That includes the battery, which needs charging to keep its power topped off.  The alternator creates electricity by taking mechanical energy from the engine and turning it into electricity.  It is connected to the engine by belts and pulleys. 

In cold weather, the material the belt is made from is less flexible than it is in warm weather.  That means it may not be turning the pulleys as effectively since it doesn't have the same grip. Also, when it's colder, lubricants, including the engine oil, are a little stiffer and parts just don't move like they do when the weather's warmer.  With that extra strain, sometimes it takes the alternator longer to recharge the battery. That, in turn, may leave the battery a little less power to start the engine when it's cold.

You may have a warning light on your instrument panel that looks like a battery.  If it lights up or if you notice your headlights flickering or not shining quite as brightly as they usually do, it could mean a weak alternator. But it also could be an aging battery, corroded battery terminals, a loose belt or another charging system part. Yes, it's complicated. 

Pinpointing the cause involves testing the battery and charging system with diagnostic equipment.  If it does turn out to be an alternator, there are options besides replacing it with a brand new, original equipment part.  Ask your service advisor for recommendations. Obviously, you want your vehicle to start reliably, especially in cold weather.  Take care of your charging system and it will take care of you.

Thoughtful Gifts for the Winter Driver

You may be one of those romantics who don't like giving (or getting) practical gifts for special occasions.  Just wait until one of those gifts helps you out of a big predicament in cold weather, and you realize that practical gifts can be life savers.

Here are a few things you may give the cold-weather driver in your life—or suggest to someone else to give you!

• A portable air compressor.  If you've ever had a flat and you can't imagine trying to change a tire on a snowy, winter day, this may just get your tire pumped up enough to drive over to the repair facility.  Some are fancy and pricey, some are only a few bucks.  They plug into the cigarette lighter/12v outlet and will take a few minutes to pump up your tire. But it could save you a tow.
• Portable jump starter. These are relatively small power units (they easily fit in a car trunk) that can jump start your vehicle that has a dead battery.  Some even have an air compressor built in.  If you've ever tried to use conventional jumper cables in freezing weather, they can be stiff and hard to manage.  Really handy when there are no other people or vehicles around and you need a jump.
• Flares.  When bad winter weather reduces visibility to dangerously short distances, flares can make the difference between someone seeing you broken down at the side of the road and them ramming into you. Flares put out far more light than nearly every other warning device; just ask law enforcement officers who carry flares in their patrol vehicles. 
• A good tire gauge.  Winter is when temperatures plunge.  When the temperature drops, so does your tire pressure, so it's important to check your air pressure properly and accurately so you don't wind up with one or more deflated (and flat) tires.  The proper time to check pressure is in the morning, before you hit the road and your tires heat up.  Properly inflated tires are important for safe traction, especially during winter.
• Kitty litter.  The lowest-tech gift of all.  Keep a bag in your vehicle and it can provide much needed traction if you get stuck in the snow.

Low Power Mystery (Ignition Coil Service)

It's no fun when your vehicle just doesn't run the way it used to.   You may notice (especially in cold weather) the engine won't start easily or when it does start, it doesn't run smoothly. It may not have much power at all. You also may have had to stop at the gas station more often, a sign your fuel economy isn't what it used to be. 

There could be a few different things that cause those symptoms, but one culprit could be a bad ignition coil. The coil takes the voltage from your battery and multiplies it before that power is sent over to a spark plug. That allows the plug to fire off a good jolt of electricity that ignites the fuel in your cylinder and powers the engine. 

There's usually one ignition coil for each cylinder (or sometimes for a pair of cylinders). If only one of them is not pushing out enough electricity, it can cause big trouble with your engine performance.  Other signs of a bad ignition coil include engine backfire, an oil leak and your Check Engine light coming on.   When that light comes on and you have some of those other signs, you need to have your repair facility check things out fairly soon because you may be damaging your engine and wind up with a far more expensive repair.

A technician will check for a computer code to pinpoint which cylinder is having the problem.  Using other diagnostics, the technician can rule out other components that might be causing the engine to misfire.  Ignition coils usually last 100,000 miles/160,000 km, but other engine conditions can cause them to fail before then. 

Your service advisor may suggest getting all your coils replaced even though only one is malfunctioning. That's probably a good idea in a higher mileage vehicle since the other coils may be close to failure, too. It's also wise to do that if your vehicle's coils are located in a hard-to-reach spot so you likely won't have to spend the money for that labor again when another one fails.
