ok, the overflow tank on my cobra is a plastic pop bottle. The fluid is filling it up and than i loose fluid i think b/c there is no top on the overflow..its just open where the hose goes it. I found a little oil above the water pump....wiped it off and it hasnt come back yet as of today. Last night after the car cooled down i sqeezed the radiator hose and it was soft and empty. What is going on....i am 90% sure no blown head gasket or anything....is it just because its overflowing a lot..should it be doing that..or is it my water pump taking a sh1t?????
