I need a diagram for the thermostat on
the 2000 pontiac grand am 3400
The thermostat is located in the thermostat housing which is located on the intake manifold under the throttle body. If you have small hands, you can remove the air intake tube from the throttle body and the exhaust crossover heat shield. Once there out of the way, you can remove one of the bolt and losses the other to slide the thermostat housing off to replace the thermostat.
If you can not get to the bolts, then your going to have to remove the throttle body and don't forget the order the new throttle body gasket also. Not that the coolant temperature sensor is on the intake manifold in front of the thermostat housing, so take caution not to damage it when removing the housing.
Thank you for using fixya and keep us posted.
