I have a 2002 Pontiac Grand AM for about 4 days now the car has been running hot. When it gets too hot the car dies and I have to jump the battery. Could this be more then a simple thermostat problem?
Could be, or there is a blockage somewhere, low on coolant, fans not turning on etc. Did you purchase from a dealer and get a 30 day warranty with the car?
If it has a V6 (most of them do) and there is air in the cooling system, they over heat. The air has to be bled out. http://www.gaownersclub.com/forum/faq.php? faq=maint_repair#faq_cooling_serv
head gasket or intake manifold gasket
