Your vehicle may be like that famous battery bunny, the one that just keeps going and going.  But while it may seem sometimes like you never need to take your vehicle in to be worked on, there are some things you should keep your eyes, ears and nose out for. They are warning you about something that needs attention at your vehicle service facility. If a warning light is on, don't ignore it; do something about it.  There are warning lights for battery, oil, engine heat, tire pressure… you name it.  And the manufacturer put them there for a reason.  They're telling you something isn't normal. So when one goes on, have it checked out soon, especially the blinking Check Engine light.  The earlier you have any warning light issue diagnosed, the more likely you are to avoid a more serious problem. If your vehicle is vibrating or shaking, it's not only annoying, it could signal trouble.  You can bet your vehicle didn't do that when it came out of the fact ... read more

If you notice that your headlights are flickering at night, that's something to pay attention to. While there could be many different things that could cause that problem, one possibility is your vehicle's alternator. The alternator takes mechanical energy from the engine and turns it into electricity, in essence a generator.  The current it makes charges the battery and supplies power to the vehicle's electrical systems.  An alternator is made up of several different parts: a pulley, magnets, coil wires, brushes and a voltage regulator.  While your vehicle is running, these parts get a good workout and, after time, they begin to wear out. Other symptoms of a failing alternator include your vehicle's lights dimming, the power windows going up and down more slowly than they used to, your power seats not moving quite as fast as before.  Another sign of a worn out alternator is engine stalling.  Vehicles with fuel injection require a certain amount of power, and w ... read more

There are some dashboard lights you should pay more attention to than others.  One is the air bag light.  If it's on and your vehicle is in an accident, your air bags probably won't do their job. Automakers began installing air bags in the late 1990's since they were mandatory in the United States, and manufacturers have included them in Canadian vehicles as well.  Safety experts say using a seat belt in combination with an air bag gives passengers the best chance of surviving a crash and minimizing serious injury. The air bag warning light takes a few different forms.  Some look like a picture of a belted passenger with an inflated air bag from a side view.  Or there may be a warning light that says something like "Air Bag," "SRS" (for supplemental restraint system), "Airbag Deactivated" or "Air Bag Off." Different things cause the air bag light to come on.  Your vehicle may have been in an accident during which, while the air bags didn't inflate, crash s ... read more

Let's face it.  New vehicles are expensive, so finding a good used one can save drivers a lot of money.  It's tempting to look through ads, find a private seller who has what you're looking for and pay a price you think is a great deal.  But when you go over to look at a used car, do you really know what to look for to uncover potential problems with it? The answer is probably no.  Used cars can look great on the outside, maybe even have lustrous paint and a super clean interior. But is it possible that vehicle's been in an accident? Does it have electrical problems you can't detect easily? Is any fluid leaking that you don't know about? Think about it.  You are about to spend thousands of dollars for a complex machine and you're considering judging its condition without much expertise.  That's why it makes sense to have a qualified technician inspect any used vehicle you're considering buying. Many vehicle repair facilities will do it for around ... read more

If you've been paying attention, you've noticed that vehicle engines are getting more and more powerful in LUCAS. At the same time, they are getting better and better fuel economy. I've gotta tell 'ya, most of that's because of technological advances in transmissions. To get a better understanding of why that is, let's talk bicycles.You've probably seen plenty of cyclists on LUCAS roads. Perhaps you ride yourself. Then you know that a cyclist's cadence is the number of times per minute he or she pedals. The ideal pedal speed is the zone where they can most efficiently generate power over a sustained period of time. The experienced TX cyclist uses her gears to keep her pedal speed in the ideal zone whether she's climbing a hill, cruising on a flat stretch or killing a downhill.Think of it this way: if you have a 1-speed bike, you really have to pump hard to get up to speed. Your top speed is limited by how fast as you can pedal. And if you're climbing a steep TX hill ... read more

You've likely heard how important oil is to your vehicle's engine. Did you know that there's one part that's responsible for holding that oil so you can use it every day? It's called the oil pan, and it sits at the bottom of the engine. The oil pan is a vital, though simple, part of your engine's lubrication system. Oil circulates through parts of your engine to keep them lubricated. It reduces friction so everything works smoothly. Without oil, friction would quickly destroy your engine. The oil pan keeps that oil contained in the lubrication system, so it's important that the oil doesn't leak out. Since it's a metal part attached to another metal part, there is a gasket between the oil pan and the part of the engine it attaches to. Various things can put stress on the oil pan and gasket, including weather extremes, the speed you're traveling and the condition of the oil. You may drive over a couple of bad roads and kick up debris onto your oil pan. All this wear and tear, heat and ti ... read more

So you thought you only had two brake lights.  Look again and you'll see one in the center at a higher level than the two on either side of the vehicle.  They're sometimes in the inside of the vehicle behind the back window, or they could be in the deck lid, on the roof or on the spare wheel carrier, But why is that third brake on your vehicle? Experts say it helps prevent rear end collisions. Tests done by installing the third brake light in taxis and fleet vehicles showed fewer rear end crashes in the ones that had the extra light. The third brake light was mandated in new passenger cars in 1986 in the US and Canada.  The requirement was added to new light trucks and vans in 1994. Sometimes it's difficult to know if your third brake light is even working.  Many vehicles have bulb warning systems that alert you to non-functional bulbs, but not all do. Your vehicle service facility will often check to see if all your turn signals, taillights and headlights are worki ... read more

The pungent smell of rotten eggs can send people running for the hills.  So when that odor is inside your vehicle, yikes!  Yolks!  The good news is that a trained service technician can search the source of that smell and stanch the stench… that comes from another words that begins with S.  Sulfur. Fuel contains small amounts of hydrogen sulfide, but they're enough to stink up a vehicle when it's not properly burned.  You may know that the smell of rotten eggs can often be a sign of a catalytic converter that isn't working the way it should.  That could be due to age, damage or an abundance of oil that's clogging it up.  If a sensor in charge of managing the fuel has failed, the engine can run with too rich of a fuel mixture.  That can overload the catalytic converter and allow some of the byproducts to escape without interruption from the chemical reaction that is supposed to prevent them from going out the tailpipe. There's another possi ... read more

Today's vehicles have some pretty amazing technology in them, including a computerized braking system we all pretty much take for granted these days.  Antilock brake systems (ABS) have been around for years but they help drivers stop in much shorter distances reliably than ever before.  When you see your ABS warning light come on, it's important to find out what's causing the problem. It's a safety issue. Often the problem when the ABS light comes on is a faulty wheel speed sensor.  (In some cases the traction control light will also come on, perhaps because of a non-working wheel speed sensor.) Your vehicle uses the speed sensors to measure the rotational speed at each wheel. That sensor sends the speed data to a computer that can then adjust braking power and prevent your wheels from locking up.  If any of the wheel speed sensors isn't working right, the ABS warning light will go on and the vehicle's computer will turn off the antilock brake system.  You'll s ... read more

Have you ever seen a ballet performance? Have you wondered how all of those dancers manage to travel all over the stage jumping and twirling and never crash into each other? That's the job of a choreographer.Our auto engines are also highly choreographed. Pistons travel up and down inside cylinders. Valves at the tops of the cylinders open to let air and fuel in or exhaust out. These valves have to open and close at precisely the right time or the engine will run poorly if at all. The movement of the valves and pistons must be in harmony with each other. This choreography is the job of the timing belt or timing chain.Timing belts, or chains, rotate the shafts that control the opening and closing of the valves. Timing chains are metal and durable enough that they may never need to be replaced.Most vehicles, however, use a timing belt. Timing belts are tough and flexible, and considering the work they do, they last a long time for LUCAS auto owners . But they do wear out. If they br ... read more
