Recently I have replaced radiator, thermostat, hoses, water pump, timing belt, valve cover gaskets etc. When the engine runs first 30 minutes the temperature is OK. After that it starts over heated and the coolant starts boilng in the plastic resorvoir tank and comes out of the bleeder vent pipe.
I checked the coolant circulation, it's OK, the water pump, fan, temperature gauge all are working. No white smoke from the exhaust, so perhaps not head gasket.
I am afraid of taking the car on the road. Please help. Thanks.
have the same problem?
