2005 Chevrolet Tahoe Question: Engine overheating
This sounds like a radiator fan problem, I would start there. - Bret Bodas
A coolant leak may develop from the water pump. The engine may overheat as a result of the coolant loss. A leaking water pump should be replaced.
Heater stopped working in the car and "engine coolant hot" light came on.
