I had a problem with the engine light coming on and the temperature gauge moving to hot. After making sure that we had antifreeze and water in the areas that require it I had to end up replacing the radiator and the thermostat (replaced twice because the first on I bought was defected) replacing the thermostat and the radiator. The vehicle is still running hot.

Are you sure the engine is overheating and this isn't a false reading from the temp sending unit?

Hello,

This could be from a blown head gasket causing exhaust gases to enter the cooling system. Here is a test to see if this is the problem.
