Did you know that having a burned out headlight can result in your rearview mirror reflecting some flashing lights? In other words, you might get pulled over by the police for only having one working headlight, because in most places it's against the law.  Not only is it illegal to drive with one headlight burned out, but it's also dangerous. You can't see down the road nearly as well at night with only one headlight, and other drivers can't see you as easily either. The good news is many newer vehicles warn you when one of your headlamps burns out. When that happens, have it taken care of as soon as you can.  While there was a time when all headlamps were pretty much the same, the same isn't true these days. There are halogen, Xenon, LED and other technologies used in modern vehicles.  Plus there are sealed beams (like those on older vehicles) and capsules. If you have a burned out headlamp, ask your service advisor for recommendations.  Usually when one side goes ... read more

Ever wonder what one of the best things is to ever happen to your vehicle's engine?  It's the little thing that usually looks like a can, the oil filter. Just like your kitchen sink strainer filters out errant particles of food from clogging your drain, the oil filter cleans out small particles that could cause your engine harm. Your engine operates in a dirty, hot environment and gathers a lot of tiny contaminants like dirt, dust, little metal shards and unlucky bugs that get sucked in.  Get those things circulating in your engine and those little particles can cause friction, which starts wearing out those finely machined metal parts.  You know how important it is to change your oil regularly.  It's vital that you change your oil filter at the same time to keep the oil as close to brand new as possible. Most oil filters look like a metal can with some holes in the bottom.  Inside there are carefully chosen materials that can screen out the contaminants while ... read more

You are heading down a flat, newly paved street when all of a sudden you feel it.  Your vehicle jumps a little bit when you're accelerating and changing gears.  You know it's not the surface of the road because it's smooth as silk.  So what did you just feel? That kind of jumping—or grinding or slipping—during gear changes could be a sign of trouble in your automatic transmission.  And it's important to get it checked out fairly soon because some transmission problems that aren't fixed early can lead to more involved and expensive repairs. By far most vehicles on the road in North America have automatic transmissions, and they are workhorses.  Unlike early cars with balky, hard-to-shift manual transmissions, the latest automatics allow you to drive without having to even think about gear changes.  But you should know about a few signs of trouble to look for if they ever start showing up. When you first get going and shift your vehicle from Par ... read more

At one time or another, most drivers honk their horn at someone who might be texting at a stoplight or not paying attention when they're driving.  But what happens when you tap on your horn and all of a sudden it won't quit? Everyone's looking at you like you're an angry jerk and all you want to do is turn it off! It helps to know the basics of what's happening when you honk your horn.  There's a switch in the steering wheel, of course, and when you press on it, it sends power to a relay which then energizes the horn.  Bingo.  Sound.  When the horn sticks on, one of these parts or the wiring has developed a problem.  With the ear-splitting noise inside your cabin, it may be hard to keep your cool, but do your best to stay calm.  Try pushing the horn several times; it may un-stick the switch if you're lucky.  If not, there are a couple of things you can try. First, if you can, pull your vehicle off the road and into a spot where you're not disrupt ... read more

If there’s one thing you should pay attention to with your vehicle, it’s the temperature gauge. It’s the one that may say C---H (that means “cold---hot”).  Or maybe yours has a picture of a thermometer on it and a blue and red zone.  If you see the needle heading farther to the “H” or red area, that means your vehicle’s engine is running hotter than it normally does. One of the most common causes of an engine running hot is a leak in your cooling system.  Maybe you’ve seen puddles of coolant under your vehicle, or you’ve smelled the coolant, either inside or outside your vehicle (it has a sort of “sweet” or fruity smell). That’s your engine giving you a warning signal that it’s time to head over to your repair facility to find out what’s going on. Your vehicle’s coolant can leak for several reasons.  You may have hoses that are deteriorating (heat and age take their toll) ... read more

Welcome to the world of infrequently-used parking brakes.  Yes, they do stick for several reasons. It's common for components to corrode and get locked up.  Sometimes if you have applied it extra hard, it can jam.  Could be a rusty cable, or it could be a spring that doesn't return the brake to its disengaged position.  Some pieces just break when they're stressed for the first time in a while. A caliper or the pivot arm it's on can also stick. There are a few things you can try to unstick it.  Carefully rock your vehicle by putting it first in drive and then reverse.  You have to be careful doing that, though, because sometimes you can damage the transmission.  You can try working the parking brake control a few times to see if that will loosen the corrosion.  If you can't unstick it, you can try driving slowly a short distance to a repair facility near you.  Sometimes it won't cause damage to the brakes, but it depends on how tightly the p ... read more

If someone told you that your vehicle could have the same power but with a smaller engine, wouldn't that sound like great idea? Just think, a smaller engine would save you money at the gas station and you'd still get the same horsepower. The technology to do just that has been around for a long time. It's called a turbocharger. Race cars and other performance vehicles have been using turbochargers for years. It gives them a power boost without the need of a bigger engine, saving them fuel and pit stops. Automakers have offered turbo gasoline and diesel engines for years, but there were problems with durability. Plus drivers had to make some driving adjustments with the way turbos delivered power. Newer turbos, though, have been vastly improved, and manufacturers are including them in more models. For example, Jeep offers its 2019 Cherokee with a choice of two engines that each make about 270 horsepower. One is a 4-cylinder turbocharged engine and the other is a 6-cylinder conventional ... read more

As the temperatures plunge, certain types of engine oil may not flow as easily as they did when it was warmer.  Makes sense, doesn't it? Just like molasses gets thicker as the temperature goes down, engine oil does the same thing. So, maybe you're wondering if you have to change your oil as the seasons change so it's just the right thickness to lubricate your engine parts.  How well engine oil flows is called its viscosity. There are different types of oil—some that have just one viscosity and others called "multigrade" oils.  Here's the difference. A single viscosity oil will flow better when it's hot but not as well when it's cold.  A multigrade oil is engineered so that its flow properties at cold temperatures are different than they are at warm temperatures.  In other words, a multigrade oil can start out in colder temperatures acting like a thinner oil and then behave like a thicker oil when it's warm.  That's a pretty cool trick and it's why mu ... read more

A lot of us LUCAS drivers like our vehicles to reflect our personalities. We're picky about color and body style. We'll customize anything from floor mats to window tints to license plates. One popular way for TX motorists to customize a vehicle is to get new wheels.

Wheels come in thousands of designs. Custom wheels can add personality, style, or sass to a vehicle. Many of these customizations involve getting a bigger wheel.

Fifteen- or 16-inch wheels used to be the factory standard, but today, because many LUCAS drivers like the look of larger wheels, many vehicles are available with 17- or 18-inch wheels. Optional 20-inch or larger wheel packages are also available in LUCAS.

If you want to upsize the wheels on your current vehicle, however, you should know it's not a do-it-yourself project. There are factors to consider to ensure your wheel change doesn't jeopardize your vehicle's safety.

First, you need to understand rolling diameter. The rolling di

Your vehicle is a complicated machine, and yes, it would be nice if you could take care of all of its problems yourself.  There was a time when vehicles were simpler and it wasn't too hard for a weekend mechanic to replace brakes, adjust a carburetor or perform a tune-up.  But vehicles are far more complicated these days, with traction and stability control, anti-lock brakes, air bags and fuel injection just a small sample of the new technologies.  Like a lot of things these days, technology changes in leaps and bounds.  Anyone who repairs vehicles has to stay up on the latest computers, sensors, suspensions, steering, electronics, hydraulics and more.  Many power steering, braking and heating and air conditioning systems that used to be mechanical are now being replaced by electronic systems.  Computers are an integral part of  much of the latest automotive technology, something you didn't see a lot of until as recently as the 1990s. Today's most hig ... read more
