I have the 170-horsepower, 3.4-liter V-6 engine offered as an option on my 2000 Pontiac Grand Am SE, which all sounds great until it overheats and I have to replace the thermostat. Luckily for me, it was a nice day and I had nowhere special to be.
How I Got My Cool Back
To lift and support the Grand Am, I used the notches in the body molding 18 inches behind the front wheels. In order to get to the thermostat housing, I had to remove the air cleaner and the exhaust crossover pipe and I had to disconnect the surge tank line fitting from the coolant outlet. Upon reassembly, I tightened the housing bolts and the crossover pipe bolts to 18 foot-pounds, and the surge tank line fitting to 15 foot-pounds. I refilled the system with half-and-half Dex-Cool coolant and tap water.
