You may need to replace your coolant temp sensor located on the engine, depending on the model, it may be located in the thermostatic housing or nearby, on some models it may be threaded into one of the cylinder heads or a water inlet line, on some models this can control your electric cooling fan and if not functional, cause an overheating problem.

Make sure and purge the air from the cooling system.
