Radiator Cap Coolant Leak
Ive replaced the radiator cap 4 separate times with 4 different caps and have replaced the radiator its self. Coolant keeps leaking out of the radiator when the truck gets up to temp. It seems like it is leaking out of the cap and not pushing up into the coolant reservoir BUT when it cools down it seems to pull from the reservoir still. Is this a case where the OEM radiator cap is the only thing that should be used and the only thing that works? v
