Hello - the fact that your car maintains a steady temperature near design temp (center of the gauge), suggests the thermostat is working properly. Overheating while idling or at low speeds is usually a problem with a clogged radiator, faulty...

Hello. This is a speed limiter built into the programming of the computer. You may be able to find an aftermarket computer programmer to add performance to the vehicle and change the speed limit of the vehicle. Alternatively, you may...

Hi Ewelina. Thanks for contacting us tonight. It is quite possible that the noise you're hearing is the radiator fan that is stuck open. This can occur when an electrical relay is damaged, but it can also be caused by...
