Give it the Boot (Ball Joint Boot Replacement)

Your vehicle may be wearing boots right now and you might not even know it.  They're called ball joint boots.  They're actually protective, flexible things that protect parts of your suspension (called ball joints) from all the hazards the road can fling at them.  If one of those ball joint boots fails and you don't get it replaced, the ball joints themselves could wind up failing, a repair that can be even more expensive.  Ball joint boots not only keep things like rocks, salt, water and dirt out of your ball joints, they also help the ball joints keep their lubrication inside and working properly.  To do that, the boots have to be made of a flexible material, sometimes rubber, sometimes a synthetic.  They do take a beating, exposed to temperature extremes and debris, and eventually they can tear or crack just because of their age.  Unless someone is keeping an eye on your ball joint boots, you may never know there's a problem.  That's why when ... read more

The Neglected Windshield (Windshield Care)

You look at it every day, yet you don't really see it.  We're talking about your vehicle's windshield, and if you're not seeing it at all, that's probably a good sign.  The fact is that unless our windshields get fogged up, hazy or cracked, we don't pay all that much attention to them.  Considering how vital front visibility is in a vehicle, paying a little more attention to your windshield will pay off in the long run. Keep it clean!  In ancient times when gas stations had attendants who filled your tank for you, they used to clean the outside of your windshield while the fuel was being dispensed. In these days of self-serve gas, we don't have that luxury any more.  But it's a good idea to clean your windshield regularly, even when it's not filthy. If you let dirt build up on the outside, it acts like fine sandpaper when you turn on your wipers when the glass is dry. Really, try to avoid turning on your wipers unless your windshield is wet.  If you must u ... read more

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 ... read more

Why You Have an O2 Sensor (Oxygen Sensor)

If someone asked you what gas made up the largest portion of the atmosphere, what would you guess? Well, it's not oxygen; it only makes up 20.9 percent.  But since we're talking about oxygen, you should know that your vehicle uses oxygen sensors to make sure your engine is running the way it should. The oxygen sensors measure how much oxygen is in your exhaust.  If there's too much, it means there's a problem with the mixture of fuel and air.  The sensor sends signals to computers in your engine and adjusts the mixture so it maximizes performance and efficiency.  It does this constantly.  Many vehicles have multiple oxygen sensors.  Some have one close to the engine, another close to the muffler.  Two measurements are better than one since they allow readings to be more accurate.  You may have a vehicle with a dual exhaust, so you'd have twice as many oxygen sensors. Your oxygen sensors can fail.  One thing that can damage them is contaminat ... read more

Singing a Different Tune (Up) (Tune Ups)

Engines required a lot more maintenance in earlier times.  You'd have to have your spark plugs, wires, rotors, caps, distributor points, fuel and air filters changed periodically.  There were mechanical adjustments of a vehicle's timing, dwell, spark gap and idle mixture, too. Unless you like to tinker with old cars, a lot of those terms won't mean much to you.  That service was called a "tune up" back then, and you can see why.  But now, computers have reduced the number of maintenance items, and a tune up is a whole lot different than it used to be.  In fact, in some vehicle service facilities, that term is also a thing of the past.  A tune up of today would more accurately be called simply periodic maintenance. Now, most vehicles still have spark plugs and wires, fuel filters, air filters and PCV valves, and they should be inspected tested and/or replaced at regular intervals.  Your vehicle's manufacturer has made recommendations on how often that ... read more

Some New Boots (Suspension Maintenance)

There are some boots that don't come in a shoe box and aren't worn on your feet.  They are called axle or CV boots, and they can be important parts for many vehicles. That CV stands for constant velocity.  CV axles are mainly used in front-wheel drive and all-wheel drive vehicles. They're also used in some rear-wheel drive vehicles with independent suspensions.  They have two CV joints, one inner and one outer, placed between the axle and the drive wheels.  That way the vehicle's engine power can drive the wheels, no matter what angle they are.  They also adjust for the different speeds wheels turn as they go around corners.  Because roads are full of all sorts of hazards (dirt, oil, water, grime), these CV joints need to be protected.  They also have grease in them to keep the bearings moving smoothly.  That's the job of the rubber boots that are supposed to keep that debris out.  These CV or axle boots are made of rubber or plastic and usu ... read more

It Is Time to Check Your Intervals

Part of the engineering that goes into designing a vehicle is testing the components to ensure that they meet durability and safety standards. Because of this, manufacturers have a good idea as to how long the parts in your vehicle will last under normal driving conditions. For this reason, they give us guidelines to follow regarding how often to inspect the various parts and systems on our vehicles.Vehicular components are required to meet certain standards. The government mandates some of these standards. Others are set by the auto industry. Recommended car maintenance schedules are designed to help Wilmot vehicle owners maintain these standards. Disregarding routine maintenance or procrastinating preventive maintenance will result in lowered performance and reduced safety for a vehicle.Maintenance schedules are designed to ensure three areas of automotive performance for Wilmot drivers: protection of the vehicle itself, efficiency and safety. Protection ... read more

Growing Old Together (Maintaining an Older Vehicle)

More and more of us are hanging on to our vehicles longer.  A company by the name of HIS Markit recently released a report that shows the average age of light vehicles in the U.S. is now 11.8 years.  Light vehicles are cars, SUVs (sport utility vehicles) and CUVs (compact utility vehicles).  In Canada, the average life expectancy of a vehicle there is around 13 years, and in the U.S., it's around 15.  Vehicles are lasting longer these days, and there are several reasons for that. One expert cites better technology and overall quality improvements.  While in past years, vehicles were made mainly of heavier steel components, more modern vehicles contain lighter magnesium and aluminum alloys, high-strength steel, polymers and carbon fiber.  They last longer and reduce the overall vehicle weight, and that can contribute to better fuel economy. Modern internal combustion engine designs have been improved, and since they use more computers, they are more efficie ... read more

Conventional or Synthetic? (Switching to Synthetic Oil)

If you keep up on technology trends, then you may be intrigued about synthetic motor oil.  It was introduced in the 1960s when Mobil came up with it.  Mobil's oil was different from conventional motor oil because it was first broken down to its basic molecules.  Then, Mobil removed additional impurities from crude oil and "tailored them to the demands of modern engines." Synthetic oil is becoming more popular now because of its advantages over conventional oil. It's more resistant to sludge forming in an engine.  It is more efficient and protects engines better under temperature extremes.  Because it allows drivers to go longer between oil changes, many feel it's more convenient.  The downside is that synthetic oil is more expensive, but because it doesn't need changing as often, the cost can be pretty comparable in the long run. Those who drive high performance vehicles (think Audi, BMW, Mercedes) are already using synthetic oil if they're following their ... read more

Don't be Fuelish (Signs Fuel Pump is Failing)

A driver of a large SUV loaded with equipment was heading on a 7-hour work trip when he stopped at a gas station to refuel.  When he went to restart his SUV, it turned over but wouldn't catch.  Try as he might, he was never able to get it started again.  Of course there are many things that can cause those symptoms, but the next day he had his SUV towed to a service repair facility.  Using their test equipment, they were able to pinpoint the problem.  His fuel pump had failed.  The pump, which was located in the fuel tank, had to be replaced, and after awhile he was back on the road, delayed, but happy to be up and running again.  What had happened is that the pump was not strong enough to deliver adequate  fuel to his engine, vital to being able to start it.  It had delivered just enough pressure in the morning to get it started the first time, but it was on its last legs.  He had been having trouble starting his SUV in the days leadin ... read more
