How do you fix an overheating problem on a 2004 GMC Sierra?
Years 1999-2007

Answer

If your GMC Sierra 1500 car overheats, the most common reasons are a coolant leak, such a leak could be found in either the water pump, the radiator, the hose, a radiator fan that no longer works normally and therefore should be replaced or a faulty thermostat. It is therefore necessary to operate in stages, check each element at a time and observe its functioning. Alternatively, a tester could immediately give you where the problem lies.
