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

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

Let's talk about something critical for all LUCAS drivers: your brakes. Your vehicle is heavy, and it takes a lot of muscle to bring it and your passengers to a safe stop – so everything needs to be in good working order. Here's an explanation on how your disc brakes work: The wheel hub keeps your wheel attached to your vehicle. The brake disc – or rotor – is attached to the hub and rotates with the wheel as you drive around LUCAS. Your brake pads clamp onto the rotor to slow the wheel.The brake caliper straddles the rotor and squeezes the rotor to slow it down. The calipers contain brake pads which press on the rotor when you put your foot on the brake. The brake piston causes the calipers to squeeze and release as you use your vehicle brakes.Your brake pads start to wear the first time you step on the brakes. Eventually the pads ... read more

Your vehicle has a way of letting you know when something's wrong. Consider a vibrating steering wheel. It certainly didn't do that when it was new, so that shake is trying to tell you something. There are a few things that can cause your steering wheel to vibrate as you drive down the road.  One of the most common is out-of-balance tires.  You may not only feel that wobble in your steering wheel, you might also feel it in the tires.  Sometimes it's not there when you're driving at lower speeds through residential areas, and sometimes it starts when you hit highway speeds.  So what is tire balance anyway?  Well, you have a rubber tire that fits around a metal wheel.  It should have the same weight all the way around.  If it doesn't, it will start getting the shakes.  Ever load your washing machine so that all the clothes are at one side of that drum that spins?  When it hits the spin cycle, it can throw that washer against the wall.  Th ... read more

You may be driving along and find that suddenly your radio stops working.  There are no numbers on the display.  Then when you get home, you notice the garage door opener doesn't do a thing when you press the button. Hmm, this was working just fine this morning.  Are the two problems somehow related?   No, your vehicle doesn't need an exorcism. This has all the signs of an electrical issue, and when you experience symptoms like those, you've probably blown a fuse.  Most vehicles have fuses just like most houses have circuit breakers (some houses still have fuses). They cut the power when it reaches a pre-determined threshold that could cause major damage if it was allowed to continue.  You might say fuses take one for the team. Most modern automotive fuses are plastic with a thin strip of metal in them designed to melt when a calibrated amount of power passes through.  The philosophy is it's better for an inexpensive fuse to be destroyed than your sou ... read more

Most LUCAS drivers know something about preventive maintenance on a vehicle. We know we should routinely replace the oil and wiper blades and other fluids. But have you heard of a PCV valve ? This little car part needs to be replaced regularly or it can cause some serious problems in your vehicle engine.PCV stands for Positive Crankcase Ventilation. The crankcase holds your motor oil and is located at the bottom of your engine.When fuel is burned in your engine, it produces waste gases that are mostly vented out through your exhaust system. But some of these gases push their way past the pistons and into the crankcase. There, these gases can mix with motor oil to produce oil sludge, which can damage vehicle engine parts through corrosion and by clogging engine passages. LUCAS vehicle owners should be advised that if the engine is running at high speeds, these gases can also cause pressure inside the crankcase to build up. This pressure, in turn, can bl ... read more

Winter is one of the hardest times to keep your vehicle clean. But did you know neglecting to wash your vehicle in winter could cost you a significant amount of money in the long run? Here's why. Many areas deal with snow and ice in the winter, and the salt and sand that are used to keep the road surfaces from being slick are also super corrosive to a vehicle's metal body and undercarriage.  That includes all the parts underneath that can be splashed with brine, saltwater and other road debris.  Winter is also tough on vehicles where there isn’t snow, sometimes from ocean salt or winter's extra humidity and rain.  If you have any breaks in your vehicle's paint, whether it be from a little fender bender or a stone chip, that corrosive winter moisture can get through those cracks and start eating away at the metal underneath.  If you can, you should get any dents or damage fixed as soon as possible so your vehicle has a protective layer of paint between road che ... read more

With the weather getting colder, you might be tempted to start your vehicle up, let it idle for 15 or 20 minutes and then get in the nice, cozy cabin.  Some vehicles offer remote starting that let you do that from the comfort of your home or apartment.  But is letting your vehicle idle like that good for it? Manufacturers say it doesn't harm the vehicle.  They say it's because modern vehicles are made differently from those in the past.  Just about all newer vehicles employ fuel injection which uses computers to adjust the amount of gasoline that goes into the cylinders.  The engine gets only the fuel it needs, taking conditions into account. Older vehicles, on the other hand, used to use carburetors.  When you started a cold engine, the carburetor wasn't able to adjust the gasoline amount depending on conditions.  Some of the gasoline would mix with oil and the pistons wouldn't get the same lubrication as they would with undiluted oil. So yes, you ca ... read more

In the hot weather, seeing steam coming from the engine compartment is something we all dread.  No one wants that to happen to them. But if you know the signs of overheating and how to deal with it, you may be able to reduce the risk of damage to your vehicle, maybe even prevent getting stranded on the road. Besides the steam coming out of the engine compartment, here are a few signs of overheating.  Your vehicle has a heat gauge that may have a needle that can go into a red zone or up to the "H" (for High) position.  You may smell odors, perhaps a burning (could be hot oil) or a sweet smell (engine coolant leaking).  When you encounter any of those signs, you know you have to do something to keep the engine as cool as possible to avoid potentially catastrophic damage.  Turn off the air conditioning and turn up the heat.  While that last part may sound odd, it helps draw heat out of the engine.  If you can do it safely, pull off the road to a spot awa ... read more

Your parents probably taught you to have common sense. When it comes to your vehicle, common scents can also come in handy. Different smells may tell you about some conditions in your vehicle that need attention. For example, you know what rotten eggs smell like.  If you smell them around your vehicle, it means sulfur can't be far away. Here's a surprising fact: Gasoline has a little sulfur in it.  There's a device in your exhaust system that's supposed to convert it to something that doesn't pollute the atmosphere. That device is a catalytic converter.  If you are smelling rotten eggs, maybe your catalytic converter is wearing out.  But it could also be a problem with your fuel injectors.  Either way, something's rotten that should be repaired. Ever smell something sweet around your vehicle, maybe a little like pancake syrup? If you sniff out a little sweetness just when your engine is warming up or after you shut off your engine, you might be smelling some co ... read more
