There could be a variety of reasons for overheating including low coolant (accompanied by a coolant leak), a cooling fan not working, a malfunctioning thermostat, or in an extreme case, a worn-out head gasket. Similar to calling your doctor with symptoms, it is next to impossible to give an accurate diagnosis of your car overheating problem without inspecting the vehicle and doing some diagnostic testing. We recommend making an appointment to have one of our cooling system specialists have a look at your car so we can pinpoint the problem for you.
