my 94 gt was overheating, it had not bein drove in nearly 3 years and im in the process of getting it right, anyway the water pump is ok, done a compression test which wasn bad, 150 c1 and the rest in around 158 - 160.so i stripped the head of to get it compression tested(gasket ok), today he tells me test was ok but the head is cracked round the exhaust manifold area, i will get a new head but this still doesn solve my overheating nightmare. thanks shane.
