When I let engine warm up, the radiator fan doesn't come on and the engine overheats. I have check the fan motor and it is good. Also, I replaced the thermostat. What else makes the fan come on automatically? If it's a fuse or relay, where is that located and do you have a part number.
Thanks much,
Fred

Dont even know the failure yet

how did you test the fan

the coolant sensor has some control over the fan

check the diagram it has a relay.
