How are you manually opening the thermostat? When filling the system with coolant did you get all the air out? Colin
all the air is out definaty. half of the radiator stays coold on thermostat side, i opend the thermostat manualy and i have no problems.
Have you tried a different thermostat or putting the one in water and heat it up until it opens and see what temperature it is opening at. I suspect you have a bad thermostat. Colin
i replaced 3 thermostat, the lest one is from the dealer.
And what about the water pump? can you tell if the coolant is flowing through the radiator with the thermostat held open?
yes, i puld the thermostat and plugh the lower hose with my hand start the engine and create pressure
Is there any coolant in the oil? Were you able to determine what caused the gasket failure in the first place? Colin
When you say it is overheating, do you mean it is boiling over or the temperature gauge climbs into the red? If the later have you checked the actual temperature of the coolant? Sorry to be going back to the beginning but I feel I missed something. These engines do have a tendency to crack the block. Colin
