Changed radiator now it is running hot


Purge air out of the cooling system. Youtube has good how-to videos on the subject.


need more info.....i dle temp down the road > also as said above..full/air out of system??drill some holes into the thermostate as shown,,, fans running ok? why was the rad.replaced ?? was everything else checked/ok?? thermostate radiator hose colasping?


agree with purging out air... find the bleeder valve and open it while filling coolant/distilled water. slightly opened bleeder valve should be spurting coolant before closing.
