Start Me Up (Ignition Systems)

When you start up your gasoline engine car, you may not know that it's using the same ignition principles as it has for decades.  You have spark plugs that require enough power so a spark can jump across a gap at its tip.  Years ago, a vehicle's 12-volt system had to produce 15,000-25,000 volts to do that, so engineers came up with something called an ignition coil that bumps up the voltage. It also has to be done at just the right interval called timing.

The first systems had a distributor, a mechanical device with a rotating disc that switched the power to the ignition coil on and off.  That higher voltage then was sent to the spark plugs at the correct time interval. But the mechanical "points" had to be replaced and adjusted every 12,000 miles/20,000 kilometers.  Engineers later replaced the switching mechanism with solid state ones, but they still needed replacement after 120,000 miles/200,000 kilometers.

The next evolution came in the 80's when the distributor was replaced with a couple of sensors which talked to a computer.  This "DIS" (distributor-less automotive ignition system) was a big advance.  Plus, it didn't use just one ignition coil for all the cylinders.  It had coil "packs" that each provided spark to two cylinders.  That way, the voltage could be boosted even higher, to 30,000 volts, which helped engines be able to ignite a leaner fuel/air mixture.

Recently have come even more improvements.  Now instead of coil packs, there's a coil that's attached to each spark plug.  No more spark plug wires means less maintenance. Plus, a stronger, hotter spark of 50,000 volts can make an engine more reliable, increase fuel economy and reduce emissions.

No matter what ignition system your vehicle uses, your vehicle service facility has a staff of technicians trained to work on the latest technology.  Make sure to have your vehicle maintained regularly so you can take full advantage of these modern engineering marvels.

That Vexing Vapor Venting (Vapor Coming out of Vents)

You may have noticed sometimes on a hot and humid day, vapor will come out of your vehicle's vents when you have the air conditioning on.  Is that something to be concerned about? Well, it depends.

Sometimes that steam or vapor can be caused by water accumulating in the vent system after it has condensed.  And sometimes water can pool at the bottom of a vent.  When you turn on the blower mower, the air hits the water and may create steam or vapor that you can see in the cabin.

One thing to check is if that vapor smells like anything.  If it doesn't, that's a good sign. You may be able to run the fan for a while and the issue may just go away when things dry out.  But moisture collecting in the ventilation hoses in a hot vehicle may be a breeding ground for mold, and that can have health consequences.

There's another possibility. Ventilation systems often have drains to get rid of any accumulated water, and debris can sometimes clog them.  A technician can clean out those drains and you'll be back in business.

One thing to nose around for is a sweet smell coming out of your vents.  Sometimes the heater core (a component of your vehicle's heater system) can develop very tiny holes.  That sweet smell may be coolant that's been vaporized by those tiny holes entering your cabin. 

It's always a good thing to mention to your service advisor any abnormality you're seeing—or smelling—in your vehicle.  By venting a little about your vents, a technician can get to the bottom of the problem before it starts "clouding" the issue.

Breathe New Life into Your Engine (MAF sensor replacement)

If you’ve noticed your vehicle is hard to start, stalling, or has lost power, the culprit may be a part with an odd name: the MAF sensor.  You may have never even heard of a MAF sensor, but it’s important that it be working correctly, or you may be experiencing some fairly significant engine issues.

All vehicles bring in air and direct it through an air filter before it goes into your engine, where it mixes with fuel to provide power to get you going. There’s a tube-like device with a sensor inside it that measures how much of that mass of air is passing through. That’s why it’s called a mass air flow sensor, or MAF sensor.  If the MAF sensor isn’t working right, the engine’s computer can’t figure out the right amount of fuel to mix with it, and your engine may hesitate or stall.  Sometimes this will cause your Check Engine Light to come on, and any time it does that, make sure you have your vehicle checked by a professional, so you’ll know what’s going on.

When you take your vehicle into your service facility, a technician will thoroughly check the system to see just where the problems are.  If your air filter is dirty, your MAF sensor may get dirty too, which might be causing the problems.  You may find your fuel economy isn’t what it used to be either.

There are other things that can cause the same symptoms, too, such as a leak in a vacuum hose. It’s also possible that the electrical connector between the MAF sensor and the engine has broken. 

The technician can use electronic diagnostic equipment to help pinpoint the exact problem or problems, replace worn parts, and test drive your vehicle to make sure it’s working correctly.

It’s also a good idea to make sure your air filter is changed regularly. A dirty air filter can contribute to a MAF sensor failure. One of the big benefits of having your vehicle regularly maintained at one facility, is they know your vehicle. So, they keep track of which of your vehicle’s parts should be periodically replaced before problems develop. 

If you keep clean air heading into your engine, it can help your engine work efficiently, and with the power it was engineered to deliver. Isn’t that a breath of fresh air?

Tire or Re-Tire? (Getting Tires Ready for Hot Weather)

Heat isn't easy on vehicle tires, and as the seasons change, make sure yours are ready to take the heat. 

Let's talk first about inflation.  Heat causes air to expand, so heat alone can raise the pressure in your tires.  If you are driving on overinflated tires, they won't have as much contact with the road surface.  In that case, it will take you a longer distance to stop.

On the other hand, you don't want your tires to be underinflated during hot weather, either.  That can cause your sidewalls to flex.  Friction will then hike up the temperature and your tire can be in danger of blowing from the added heat.

Other things can cause problems, such as uneven wearing.  Your service advisor knows the signs to look for and can diagnose where the wear is and what is likely causing it.  Another thing a technician will look for on tires is tread depth and the condition of the sidewalls.  Any cuts, cracks or bulges could be indications that your tire is not healthy. 

Oh, and one other thing.  Your tires could have plenty of tread left on them but still be dangerous.  And that is because rubber ages, gets brittle and cracks after time.  (Ever run across an old rubber band in a drawer that has never been used but breaks the second you try to stretch it? 'Nuff said.) Some tire manufacturers recommend replacing tires after 6 years of their manufacturing date.  Your service advisor can read a manufacturing code and tell you how old your tires are. 

Tire manufacturer Michelin used to have an ad slogan that said, "Because so much is riding on your tires." That includes you and your passengers.  Always keep healthy tires on your vehicle and make sure they're ready for whatever season it is.
