I have a 1995 Pontiac Grand Am 2.3L Quad 4. The upper radiator hose burst yesterday and so I replaced the hose. Then I started it up after putting some water in in it and ran it until it heated up. The engine started to run hot. So, I took out the thermostat, checked it in some boiling water, and it worked fine.
Do you have any idea what might be happening here? My dad suggested that it could be the head gasket, but the car is running normally (no knocks) and would that cause the upper radiator hose to burst anyway? Thanks for any help.
have the same problem?
