I just replaced my thermostat in my 97 olds cutlass supreme,. what a nightmare.

I've double checked my work and cant find anything wrong I did. But your probably right about it. Where is the throttle body gasket? The two steel bands that go to the throttle and wraparound the (wheels) one is green and one is black. Is the black one with a shorter band, supposed to move with the green? It moves only if I push it by hand.

I got the idling fixed but it still is overheating after replacing thermostat, and 2 fan relays, and temp sensor. But fans don't seem to want to come on. I saw them work once. Any hints?
