Either you have a cracked head/engine block OR your head gasket is bad. This motor was notorious for bad head gaskets... Do a pressure test of the cooling system to check for symptoms. two possible reasons ,your timing is out of sync,or your cylinder head gasket is leaking,one other possible cause is a leaky hose . Or your radiator is clogged internally or externally and needs cleaning/flushing. You may also have air trapped in the system if you did not bleed it properly. Another possibility is that the cooling fan is not functioning properly. And one last possibility is the thermostat was installed upside down.

Answerwhere is the thermostat on a 2000 Pontiac grand am Instructions on how to change a thermo..Hello, this page has instructions on how to install a new thermostat on a 99+ Grand Am. Also, not listed on the page as an instruction but something I did when changing the thermostat was to take off the throttle body which made getting to the inlet manifold bolts much easier. The bottom bolt was particulary hard to get too, the top bolt was not too bad. Good Luck. http://www.grandamgt.com/thermostat-pfyc.HTML
