I have a 95 Honda Accord LX that has a 2.2 L non vtec. After the car is cranked up for about 15 to 20 minutes it starts overheating. It is blowing steam out of the radiator overflow hose. I have done a compression test to check the head gasket all cyinders hold good compression. I have also checked the fans to make sure they are working properly and the thermostat. What could cause it to build up pressure like that?

 

An clogged radiator can do it. Even though you checked it sure sounds alot like a headgasket though...........
