Engine temperature gauge; overheating


To reduce weight and maximize efficiency, almost all car manufacturers today have resorted to using aluminum, rubber and plastic to build their engines and transmissions.

While they have tremendously improved miles-per-gallon efficiency to levels unheard of before, they have also indirectly caused these very same well-oiled machines to fail much more rapidly when they overheat.

You see, the very same "features" of these new engines of low tolerances and high flexibility using aluminum and plastic, make up the very same recipe for their expeditious failure during an overheating, a condition which causes the plastic to melt and the aluminum to expand and warp so quickly that a major engine and or transmission failure in many cases almost unavoidable.
This most certainly highlights to great extent the importance of your cars cooling system, get an appointment to get your cooling system checked today.

No Start

So say you were driving and your car just died. Or maybe it was parked, and you went to start it up but you can't. What would you do?

The first and most important thing is for you to note how it died. Just quit, died slowly, any smoke, noise, lights... If this isn't the first time it happened, does it only happen when turning? When it rains? or on a hill? And so on.

The second most important thing is to not mess with the car. Many customers allow the tow truck driver to "try a few things" to get the car going in order to line it up for the tow, and when the car arrives at the shop, the condition has disappeared. Thereby we will not be able to know what caused the failure. Remember, in most cases, we can only diagnose a problem that is happening, so a car that does not start is a good thing if you want us to find the problem quickly.

And the last thing is that you know that we have skilled techs and state-of-the-art diagnostic equipment to properly diagnose your specific vehicle.

Tachometer battery light on


Your car's battery is at the heart of your electrical system, it not only supplies the necessary power to start your engine, but it holds the reserve power to power up all the electrical and electronic systems that your car might come equipped with. A problem with your car's battery may spell trouble for the entire vehicle if not treated right away, and can, in some instances, cause undesirable effects to electrical components such as the alternator and various electronic control modules found on today's high-tech vehicles.
