Question about 1999 Pontiac Grand Am GT
Posted on Nov 11, 2008
If u dont have a leak, then the coolant aint the problem, my guess is its the thermostat, this is how it works, you turn the car on, the thermostat is closed, re-circulating the coolant in the engine block until the engine hits "normal" operating tempurate. When it reaches normal operating tempurate the thermostat opens allowing the hot coolant to cool down some what through the radiator, and continues to circulate, my guess is the thermostat is stuck closed, not allowing the hot coolant to escape thus keep on heating up til u smell it. The problem is i dont have a pontiac to tell you where the thermostat is located specifically, u can buy yourself a haynes manual for $20 or so to help u in future cases which is how i learnt most the stuff i know. All i know is if u follow the upper radiator hose away from the radiaotr to the engine block you should come across a bleed screw, its beyond that and the thermostat housing is attached to the engine block, in my impala you have to take apart the air duct and cleaner housing to even get close to it. It may be easier in the pontiac i dont know, u can buy a thermostat from an auto parts store, some some with a seal built in some dont, if they dont youll need a new seal too, shouldnt cost u more than about $15-20 to D.I.Y. Wish i could help you further. Good Luck
