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.

A "Mounting" Problem (Motor Mounts)

You know how heavy your engine and transmission are, so you can imagine how tough the parts that hold them onto your vehicle's sub-frame must be.  Not only must they support the weight, they also have to isolate vibrations and noise from the passenger cabin.  Pretty tall order, wouldn't you say?

The parts that face that task daily are called the motor mounts, or engine mounts.  They are usually made of rubber with steel brackets.  Others contain a liquid for vibration and sound isolation. 

Most vehicles have three or four motor mounts, and while rubber or hydraulic liquids do a good job of damping the vibrations from the engine, they also have their limitations.  The problem with rubber is that it gets old and brittle.  Plus, if there's an oil leak anywhere in your engine and oil gets on the rubber motor mounts, rubber will deteriorate even more quickly.  As for the liquid motor mounts, they can develop leaks and stop working. 

Here are signs a motor mount is going bad.  You may hear a loud clunking or banging sound under the hood.  That means the weight of the engine is shifting around enough to bang against other metal parts.  You may feel bad vibrations, and the engine may feel like it's moving around in a strange way.

When things get to that point, your vehicle can be damaged from that heavy engine knocking against things, and its time to replace one or more motor mounts.  Schedule a visit to your vehicle service facility. There, a technician will assess your motor mounts; if one bad one is found, it's not unusual that others are likely to fail soon and should be replaced before they do.

Because all vehicles are configured differently, some motor mounts are easily replaced.  But others can be much trickier, take a lot longer and therefore are more expensive to replace. 

It's important for your engine's health to make sure motor mounts are sound and solid.  You will maintain that quiet, vibration-free ride and could save your engine and transmission from major wear and tear.

The Right Automotive Fluids for Burlington Drivers

All those automotive fluids can be confusing for Burlington drivers. Recent years have brought new grades of engine oil, types of transmission fluid, coolant and brake fluid. The right fluid protects your vehicle and helps it perform at its best. The wrong fluid won't work as well and could even cause damage.

In addition to new grades of engine oil, many vehicles now leave the factory with synthetic oil. People in Burlington should always use the grade recommended by their manufacturer.

All coolant, also called antifreeze, used to be green. Now there are several other colors of coolant sold at Corporate Autoworks in Burlington. Each type is designed to protect the cooling system components that are particular to your vehicle. The wrong stuff can void your vehicle cooling system warranty and could even cause engine damage.

Most passenger vehicles on Burlington roads today use either DOT 3, DOT 4 or DOT 5 brake fluid. Your vehicle power brake system is specifically designed to use ONE of these types – you need the right one. Higher numbers do not necessarily mean a higher, upgraded fluid.

Now, the thing is knowing that your vehicle requires specific grades and types of fluids; using the right fluid is good and using the wrong ones is bad. Once you've got that down, it's easy to remember to check with your friendly and knowledgeable pros at Corporate Autoworks or your vehicle owner's manual to find out which automotive fluids to use.

Visibility Disaster! (Windshield Washer Pump Replacement)

Let's say you live in a cold climate where the snowy, icy weather challenges you to clear the salt and debris tossed up on your windshield.  You push your windshield washer switch expecting a good stream of fluid so the blades can wipe the glass clean. Yet nothing comes out.  Nada, zip.  What's going on? You know you filled up the windshield washer reservoir within the last week or so. 

Well, there could be a few things causing your windshield washing system to fail.  One culprit? The hoses that are supposed to carry that fluid from the washer pump to the spray nozzles may be frozen, or maybe they're cracked and leaking. It could be the nozzles themselves are stopped up, either iced up or jammed full of debris.  Your windshield wiper/washer switch could be worn out or the electrical system may not be conducting power to the washer pump. 

It's important that this system work properly, especially on days when the sun may be in front of you and your windshield is covered with a cloudy, icy mess.  Seeing what's going on in front of you may be like trying to peer through frosted glass, and that's not a safe situation for you or the drivers around you. You need to have this checked out by a technician as soon as you can.

Let's say the technician discovers it's not any of those components.  Turns out it's the electric windshield washer pump itself that's failed. After replacing it, everything is working fine, and you can see again.  As so often is the case with today's complex vehicles, figuring out the root cause of a problem can be tricky.  Rely on your vehicle service facility since they have the know how and diagnostic equipment to make sure your view of the road will always be crystal clear.
