I replaced the thermostat. The water tank I replaced eight moths ago. After running the car for and hour or so the water tank fills up and over flows. There is no water in the oil and no oil in the water tank. The engine runs great. I pulled the water tank cap off it parts were loose I blew on it with no back pressure. Replace the tank and cap with a new unit under AutoZone warranty. The cap says 15 psi I blew on the new cap still had very little back pressure. Sill have same problem. Is the new thermostat bad? Could there be a bad head gasket even with the engine running good?
have the same problem?
