If you smell gasoline in your vehicle, pay attention to your nose. That's because it has an important message for you. Newer vehicles should never have a gasoline smell inside. One of the most dangerous conditions can come when your fuel line system has a leak or multiple leaks. Vehicles with fuel injectors are under pressure, meaning a crack or small hole in a fuel line can allow vaporized fuel to escape, sometimes around hot engine parts. Gasoline vapor and hot metal? You see the problem. One of the most common causes of a gasoline smell inside a vehicle is a fuel tank leak. The gas tank can rot or be punctured by road debris. A Craig's Car Care Inc technician can evaluate the condition of your fuel tank and suggest either repair or replacement. Fuel injectors can develop small leaks around their seals or O-rings. Those can deteriorate over time as the material they are made of gets old and less flexible. A technician can replace those parts. Modern vehicles contain something called ... read more

Sometimes the movie is better than the book, sometimes it's the other way around.  But when it comes to your vehicle, the best book of all is the owner's manual. The plot is simple: Owner wants long life and dependable performance from the vehicle, manual has the way to achieve that long life and dependable performance. And yet, it's amazing that some people will own a vehicle for years and never even crack this book.  They'll only read it when they absolutely have to, for things like finding out how to change the clock.  Ok, so you're probably not going to rush right over to your glove box and start reading the owner's manual cover to cover.  We know that.  But just think of what you can get out of it. Consider this.  Those who wrote or helped write this book include the engineers who designed it and the people who tested and refined it.  They know more about your vehicle than anyone, period.  They know how long a part is likely to last and what ... read more

No one likes to be greeted in the morning by having someone screech at you.  The same goes for a loud, high-pitched noise your vehicle greets you with every time you start the engine.  If you're wondering if that's normal, no, it isn't.  And it is worth getting checked out.  The good news is that it might be nothing serious.  Then again, it may be. The first things to suspect any time you hear a high-pitched sound coming from the engine are belts.  They have tension on them and they're trying to turn lots of different pulleys, pumps and other equipment the engine needs to work properly.  The noise could come from the belts starting to wear out and dry out. If one of those belts breaks at an inopportune time, not only can it strand you somewhere, the damage to the engine could be very expensive to fix. Other things that will cause a high-pitched sound are the pulleys and tensioners.  The tensioners keep the right amount of pressure on the belts an ... read more

If you have a front-wheel-drive vehicle, it has components called CV joints which enable you to turn your wheels smoothly. The CV stands for “constant velocity.” In essence, it’s a set of gears that connect a shaft that allows power from the transmission to be sent to the wheels.  When you turn the wheels, no matter what angle, the input velocity rotation will be equal to the output. Thus, the name, CV (constant velocity) joint. Other vehicles with 4-wheel drive and all-wheel drive also use CV joints.   If one of your CV joints isn’t working right, you may find your vehicle difficult to handle.  If one breaks, your vehicle may stop moving.  So, it’s important that CV joints be in top working condition.  The joints need a lot of lubrication, so they are surrounded by grease.  There’s a rubber enclosure around them called the boot which holds the grease in and protects CV joints from the elements.

Tires are so reliable these days that few drivers pay much attention to them.  But tires wear out.  They have a tough job since they are the only point of contact between your vehicle and the road.  They have to get your vehicle going from a stop, keep it going, make sure it is headed in the direction you want it to go, and –importantly – slow and stop it.   The only time many drivers think about their tires is when there's a problem, such as a flat.  Or, they may lose control when they find their vehicle isn't stopping or steering like it used to.  One major safety organization estimates that 1 out of every 11 crashes is related to a tire issue.   Many of those problems are caused by tire tread wearing out.  The rubber is worn off by friction after hours and hours on roads.  The sidewalls can also be damaged by your tires hitting curbs, potholes, or other debris. Plus, rubber ages as time passes.  We recommend you let us in ... read more

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

Even in the months where temperatures are cooler, heat is still an enemy of your vehicle.  When your engine runs, it creates heat, so there are numerous heat shields that protect other parts from those higher temperatures. Heat shields are installed around several areas of the exhaust system.  Others prevent heat from reaching parts of the vehicle.  Still others prevent heat from reaching the ground (or maybe grass underneath) and starting a fire.  If you remember your space travel history, you'll know how important a heat shield can be. John Glenn was the first American to orbit the earth, but during that maiden orbital flight, a sensor on board was indicating the heat shield on his capsule, Friendship 7, was loose.  If it had come off, his spacecraft could have burned up upon re-entry.  Fortunately, the heat shield stayed on, and Glenn made history. Unfortunately, the heat shields on your vehicle don't have warning systems like the space vehicles did.&nb ... read more

If you’ve noticed your vehicle is hard to start, stalling, or has lost power, the culprit may be a part with an odd name: the MAF sensor.  You may have never even heard of a MAF sensor, but it’s important that it be working correctly, or you may be experiencing some fairly significant engine issues. All vehicles bring in air and direct it through an air filter before it goes into your engine, where it mixes with fuel to provide power to get you going. There’s a tube-like device with a sensor inside it that measures how much of that mass of air is passing through. That’s why it’s called a mass air flow sensor, or MAF sensor.  If the MAF sensor isn’t working right, the engine’s computer can’t figure out the right amount of fuel to mix with it, and your engine may hesitate or stall.  Sometimes this will cause your Check Engine Light to come on, and any time it does that, make sure you have your vehicle checked by a professiona ... read more

It’s likely happened to you once or twice.  You head to your vehicle, open the door, turn the key and… lo and behold, your battery is dead. Now you’re stranded, may have to get a jump or a tow, and you’ll definitely be late for wherever you were headed. While your vehicle may sometimes give you warning signs, other times it doesn’t.   As many as one out of every four vehicles will have to have its battery replaced in the next 12 months.  If you don’t want to be surprised the next time your battery fails, consider having it tested. There are different types of battery testing.  One measures voltage. Another checks for something called conductance.  By sending a certain type of electric current into the battery, it can measure how healthy your vehicle’s battery is.  There’s also a load test.  It checks how your battery is working while drawing power from it.  Newer test equipment found in professiona ... read more

A set of new tires isn't probably high on anyone's list of exciting purchases.  But since your life is literally riding on them, it's probably a good idea to know when it's time for you to buy new ones. If you've been feeling your vehicle slipping more in wet weather or it takes a longer distance to stop, those are a couple of signs you may need new rubber all around. Here's how to make your decision. First thing to do is look at your tires.  The surface of the tire that contacts the road is the tread. When that tire was new, the tread was deep (the grooves in the rubber that provide traction). If they're starting to look somewhat smooth, you have a seriously worn tire that definitely needs replacing.  Bring your vehicle in for us to look at your tires and we can check your tread with a tread gauge. Also look at the sides of your tires.  If they have cuts or cracks in them, or if you see signs of bulges or scrapes made by hitting curbs or potholes, those could be si ... read more
