I would not suggest disabling your ABS at any time, as it compromises vehicle performance and safety. As for you traction control, you should be able to turn it off manually using the dash mounted button. Your owner's manual will...

The movement in the rack shaft is normal as far as I have seen in the video. With everything hooked up, use jack stands on both sides of the car to and support it below the lower control arms. Once...

A small coolant leak will in time become a bigger issue. It is not good for the engine to be overheated because it can damage the engine internally. Water is okay to use for a temporary fix. Any condition with...

I would recommend checking the Kelly Blue Book Value for your car which is relevant to your particular zip code. This should give you an indication of generally what the car is worth. You will of course want to discount...

I am from the deep south and do not see any snow, but have been in areas of heavy snow in my career. My first thought would be that the vehicle rear springs were subjected to being compressed for a...

Hello, thanks for writing in. If the flexplate was changed within the last year, then I would usually start by isolating that area of the noise. This noise can occur if the bolts are coming loose. If they are fine...

There are a number of "switch connections" that all have to be successfully closed/connected in order for the fuel pump relay to be energized. These include: whatever security mechanism may allow/disallow a "Start" sequence, the ignition switch itself, a Neutral...

Hi there. Given the description of not being able to start your vehicle, when it is cold and jump starting the vehicle without any problem. This leads me to believe the battery does not have enough cold cranking amp capacity....

You may have a failing voltage regulator that could be allowing the alternator to supply too much or too little amperage to the battery resulting in the battery never maintaining a consistent charge as it is designed to. The voltage...

Hello. If the noise is coming from under the valve cover I am certain there is an internal engine problem in the cylinder head. The easiest way to test engine internals is by performing a compression test. However, a compression...

Check the voltage at the battery terminals for 12 volts at rest. While cranking the voltage shouldn't drop very much, about 10 volts. Jump the vehicle and observe the voltage while it's running. If the voltage isn't above 13.5 volts,...
