Why is my jeep overheating? I replaced the radiator, thermostat, and temperture sensor. No indication of a blown head gasket. Fan clutch isn't bad. I can't figure it out.
have you had the coolant temperature sensor replaced?
yes, I put 3 gallons of pre diluted antifreeze into the radiator after flushing everything out with water.
There is a separate sensor usually on top of the intake manifold that shows the temperature, if that's bad then you will get faulty reads
