You know your body temperature is supposed to be 98.6 degrees F, 37 degrees C. Your vehicle has a normal temperature, too, and if you pay attention to it, that can save you some big headaches down the road. Many vehicles have a temperature gauge on the dash that takes the temperature of the engine's coolant. Some have a thermometer symbol, some read C-H (cold to hot). Many will have a red zone that shows when water temperature is getting into the danger zone. Others are digital and have a red warning light that signals overheating. And some vehicles have a light that goes on when the engine temperature is out of the normal range. If your vehicle has a gauge, pay attention to it. If you need help locating it, ask one of our Lighthouse Automotive experts to give you a quick explanation. Chances are when the vehicle has been running for 15 minutes or more, the temperature gauge will settle into its own "normal" zone, often just below the midway point.&n ... 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

You may have heard at one time or another about something called a timing belt or timing chain in your engine. And you may know that if they fail… well, let's just say that there can be some major engine damage. So obviously, we want our timing belts and chains to be in tip-top shape. One part that helps keep them running the way they should is the timing cover. As you can probably guess, it's something that covers the belt or chain. The timing cover protects both belts and chains from dirt and road debris. Timing belts also need to be lubricated so their covers allow them to be lubricated as well. They have a gasket that insures a good seal for the engine. If that gasket breaks or develops a leak, then engine oil can escape, and loss of lubrication is never good for an engine component. Other symptoms of a failed timing cover are leaking coolant, a metallic sound coming from the front of your engine or your Check Engine light coming on ... read more

It's bad enough in cold weather when ice and snow block your visibility. Add to that fog on the inside of your windows and you could be driving blind. So here are a few tips on how to keep your windows from fogging up when there's a chill in the air. You probably know fog is really condensation, when moist, warm air meets a cold surface and turns to liquid. If your windshield fogs up, you probably turn on your windshield defroster. Most defrosters blow heated air on the windshield glass to warm it up so it won't condense the moisture. Many also turn on the air conditioning to reduce the moisture. That same strategy can work on the rest of the windows. First, turn up your heater's temperature setting. The hotter the air, the more moisture it will hold. Also, turn off the "recirculating" setting since you want all outside air to come in. Then switch on the air conditioning. It will remove the moisture from the outside air that i ... 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

Who thinks about their fuel gauge? You probably don't… until it doesn't work any more. Then you have to guess how much fuel is in your tank, and that's no way to live life on the road. Fuel gauges, like every other part in your vehicle, can fail. And when yours stops working, you will probably want to head over to your service facility soon, because no one relishes running out of fuel. The fuel gauge system is much more than just the gauge you can see on your instrument panel. Most systems have a float inside the fuel tank that goes up and down depending on the fuel level. It's called the fuel sending unit, and it sends an electrical signal to the gauge (on the dash) telling it to display how much fuel is left in the tank. So, what could go wrong? Well, a few things. For one thing, corrosion from bad fuel can cause it to stick and it won't move up and down any more. So you could fill up your tank and the gauge would still rea ... read more

Rust. It's worse if you drive in places that use salt on the roads in winter, or if you spend time driving near a body of salt water. But any vehicle has to deal with rust after years on the road. And it's not just that rust can eat away your vehicle's body and fenders. It can be a real problem around your suspension, drivetrain or any place where there's metal. Rust takes its time. You don't see it until it's already done its dirty work. It can wreak havoc with your electrical system. Sure, vehicle manufacturers do their best to keep it to a minimum, but especially with road treatments like brine around, their task is a difficult one. The one spot everyone notices is in the paint. You see a little bubbling under the once-smooth surface. By the time it bubbles, it's well involved in rotting away that spot of your vehicle. You wouldn't believe how just a little thing can start the process on its way. A stone chips the pai ... read more

We've all been there. You park your vehicle on a steeper than usual hill and worry about it rolling down while you're running your errands. So you decide you'll use the parking brake. When you get back, you release the parking brake, hit the ignition, put it in gear and—uh, oh—you can feel the parking brake is still on. It's stuck. What do you do now? 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, 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 ... read more

Distracted driving is bad, you know that. Daydreaming, talking on the cell phone, putting your makeup on in the rear view mirror. All bad. But there's something else that causes more than twice as many accidents, according to a recent study. And that's people who don't use their turn signals. Maybe you're one of them. One survey said nearly a quarter of drivers were just too lazy to use their turn signals. Others said they didn't use them because they weren't really necessary. Traffic laws may dictate otherwise, but statistics show police don't write that many tickets for turn signal violations. You may have encountered the driver who cuts into your lane without signaling a change. Often, that person does it deliberately to catch you off guard so you won't invade his or her space. And when it comes to young drivers using turn signals, one insurance company survey showed more than two-thirds of those they talked to admitt ... read more

If you've ever felt your vehicle hesitate, go, then hesitate again, you might think there's something wrong with the transmission. After all, it's not moving smoothly down the road. But there are plenty of malfunctions that can cause those symptoms, one of them being something you may have never heard of: the EGR valve. EGR stands for Exhaust Gas Recirculation. It's a system that channels small amounts of exhaust back into the engine to cool down the cylinders and reduce polluting gases. Those include nitrogen oxides that can cause smog. The EGR valve regulates how much of the vehicle's exhaust gas is recirculated. After years and long distances traveled, that valve can get clogged or fail. Sometimes the EGR valve can stick open. When the EGR valve isn't working properly, your vehicle can start releasing those nitrogen oxides and pollute the air. The symptoms of a malfunctioning EGR valve include: Engine losing power Engine idling roughly Pinging and knoc ... read more
