Hi all,
My defender was prone to overheating and pressurising the cooling system so after following a few threads on the forum I bled and refilled the system, to no avail. I then changed the head gasket, correct holes etc, and now the system is even more pressurised, and the coolant boiling only minutes after ignition. The engine heats up very quickly and Im wondering if theres a crack somwhere in the head, even though it looked perfect out of the car, and was checked carefully for any warping. Any advice appreciated.
