Road Trip? Check! (Trip Inspection)

After months of postponing travel far away from home, a lot of us can't wait to hit the road and scream "Road Trip!" again.  But how long has it been since the vehicle you're planning on taking has had a thorough inspection? And is it roadworthy for several days on the highway? Time to schedule a professional trip inspection in our service center.  When it comes to long trips, before you go, make sure you can stop.  We can perform a break inspection.  Our technician will visually inspect your brakes for wear and how much life is left in the brake pads and rotors.  They'll also check your brake lines and fluids for fitness and fill. If it's going to be a long trip, it's important that your engine stays lubricated.  The technician will see when the last time you had an oil change, check the levels and inspect the system for leaks.  If you are close to needing an oil change, it's best to have it done before the trip because no one wants to interrupt a va ... read more

What is a TPS? (Throttle Position Sensor)

You know you have an accelerator pedal; step on it and your vehicle is supposed to go.  But did you know there is a part in your vehicle that keeps track of where the throttle is? It's called the Throttle Position Sensor, or TPS. The TPS is a sensor that helps your vehicle figure out the right mix of air and fuel is reaching your engine.  It does that by keeping track of the throttle and sending that information to your vehicle's computer.  Other factors play a role in how well your engine is performing, including air temperature, how fast the engine is turning over and air flow.  When the TPS isn't working right, you may find your vehicle won't accelerate or doesn't have the power you're expecting when you press on the accelerator.  In some cases, it may accelerate on its own.  Sometimes your vehicle won't go over a certain speed.  Your Check Engine light may go on. Any of these symptoms should be checked out soon.  If your TPS stops working rig ... read more

3 Winter Windshield Tips (Care of Windshield)

Cold weather can present some real challenges when it comes to your vehicle's windshield.  Think of it.  Your windshield is your window to the world when you're driving, and clear visibility is extraordinarily important for safe travels. So here are 3 tips to ensure that your windshield can do its job during the cold weather. Don't ever pour hot water on a frozen windshield.  Let's say you head outside and see your vehicle covered with ice. You think, hey, maybe I can heat up a pot of water on the stove and melt that off fast.  Don't do it!  You run the risk of shattering the glass the second that hot water hits the frigid glass.  Ditto for using a propane torch.  Glass does not do well with sudden temperature changes.  Instead, turn on your engine and start the defroster, which heats the windshield up gradually.  Use a plastic scraper designed for windshields (don't EVER use metal to scrape) and be patient.  Don't hammer on the ice to ... read more

Let's Clear Some Things Up (Headlight Restoration)

You know how exposing your skin to sunlight can cause sunburn and other unhealthy things.  Sunlight can also create major problems for your headlights.  After they've been exposed to ultraviolet light, acrylic headlights can yellow and fog due to oxidation.  And when that happens, less light can pass through the plastic, reducing the effectiveness—and safety—of your headlights.  It's not just the UV light that causes headlights to turn cloudy.  Road grime and debris gets kicked up and can scratch the plastic, diffusing the light that should pass through them when they're clear.  Plus, when your vehicle was new from the factory, the headlights had watertight seals all around to prevent moisture from getting into them and fogging them up with water vapor.  Just like clouds can hide the sun, tiny water molecules can diffuse the light from your headlight bulbs.  Sure, you could buy replacement parts and start fresh.  But the good new ... read more

How Far We've Come (Newer Vehicle Technology)

Automotive design has come a long way since the days of the Model T, especially when it comes to safety technology.  You can thank computers for a lot of the latest innovations.  Here are a few that have been making their mark in recent years. Adaptive cruise control.  This is cruise control with a brain.  Not only will adaptive cruise control keep your vehicle going at a steady speed, it will also slow it down and even stop it if the vehicle ahead of you slows down and stops.  Automatic emergency braking.  We've all been distracted while driving, and you've probably been in a situation where the driver ahead of you has suddenly stopped.  Or maybe your attention wandered for a minute and you looked up to see your vehicle closing in fast on the car ahead of you.  (After all, there are a lot more distractions in your vehicle these days.)  New systems that use cameras, lasers and other types of sensors will warn you to start braking.  If y ... read more

No Fountain of Youth (Aging Tires)

Can you think of anyone who enjoys aging?  Wrinkles where you don't want them, gray hair, eyes that won't focus any more, no stamina.  Believe it or not, your tires age, too, and they don't get better the older they get.  And here's the important thing to know, even if they can still pass a tread depth test, they may simply be too old to be safe  Here's the best way to understand this.  Have you ever found an old deck of playing cards with a rubber band wrapped around them?  Try stretching the rubber band.  SNAP! It's all cracked and brittle.  And you haven't stressed that rubber one bit since the time you put them in that drawer. Now you know what's happening to your tires.  Rubber ages.  Just like us, the day we come into the world, we start to go downhill (no pun intended).  Oh, engineers are able to make a tire last longer than ever before.  But that gas that keeps us alive—oxygen—seems to love to chemically mi ... read more

A Clean Start (Battery Cleaning)

Your vehicle is loaded with electrical devices. Computerized components are everywhere, so good electrical connections are important.  Those begin with your vehicle's battery, so it's important that its connections are in top shape. Ever had a flashlight that didn't work, took out the old batteries to replace them and noticed the old batteries were all corroded? The same thing can happen to your vehicle's battery.  The battery type used in most vehicles is a lead-acid, which can be very corrosive.  Corrosion can build up around your battery's terminals that can prevent the electrical connection from being as solid as it needs to be.  You may have even seen discoloration around your battery's terminals if you look under the hood, a sign of corrosion. Or you might notice visible signs of fraying or loose battery cables. All of your vehicle's components are affected by vibrations from the engine and road surface imperfections, and the battery cables take a lot of jostl ... read more

Sounds Exhausting! (Exhaust Service)

Most of us know a bad muffler when we hear it.  That loud, rumbling sound is unmistakable. Did you also know you can get a ticket for driving around with a loud exhaust system? If your exhaust system has a leak in it, it may be allowing poisonous gases inside your vehicle and could make you seriously ill (or even kill you!) if you breathe too much in. Unfortunately, your exhaust system faces a lot of destructive forces out on the road.  Rust is the worst, and not just in colder climates where they use salt and brine as de-icers.  Exhaust systems can rust from the inside out when moisture condenses inside the pipes.  Vibrations and jolts from rough roads (and the occasional run in with a rock or a curb) can wreak havoc with exhaust systems.  Even a bad oxygen sensor can send too much fuel into the catalytic converter, and the resulting heat can wind up destroying this very expensive component. Your exhaust system is made up of several parts, and all need to be i ... read more

Steering You Right (Tie Rod End Replacement)

For drivers, S stands for safety.  And there are three other words that start with S that are all equally important: starting, stopping and steering. For your vehicle to be at its safest, all three functions must be in top shape.  Steering is one of those things we take for granted.  After all, you turn the wheel and your vehicle changes direction. But sometimes you might notice your steering is a little off.  Maybe you've noticed you turn your wheel slightly and your vehicle doesn't turn. You may feel a little vibration in the wheel that increases when you go faster.  You may hear a little squeak from the wheels when you steer and you may notice your tires aren't wearing evenly. These are signs that your tie rod ends may be failing. Tie rod ends help connect your vehicle's steering mechanism to the wheels.  They can wear out after you've hit one too many potholes or just from constant use.  They can cause sloppy steering and loose handling, and they ... read more

Alleviate the Creaks and Squeaks (Chassis Lubrication)

If your vehicle creaks and squeaks when you drive down the road, it may mean that some of the metal parts are rubbing against each other and need to be lubricated.  Those could be parts of the suspension, steering system and the drivetrain.  Years ago, most vehicles had to have their chassis (what you think of as the frame) regularly lubricated.  Newer vehicles are made with what some call "lifetime lubrication," but there are still parts of the chassis that need to be maintained with lubricants.  Your service advisor can help you know when that needs to be done. In your owner's manual, the vehicle's manufacturer lists components that need regular maintenance. Things like u-joints, steering joints, sway bars, bushings and joints in the suspension. Some of them may have that "lifetime lubrication," while others may not. When you bring your vehicle in for service, a technician will look for any parts that have grease fittings.  They will inspect these components ... read more
