when it is cold take the cap off the radiator and start the car and let the air out
The above answer is incorrect. The cooling system on the Grand Am requires you to bleed the system. There is a bleeder screw on the top of the motor, just follow the black tubing and you'll see it.
how do i bleed my accord v6 2000 coolant system, its has air and the rev's gone up & down......
The Villager engine does not have a coolant bleed valve.
Replace the caliper and bleed the whole system
You need to first drain the coolant, to lessen the mess of spilt coolant. Next you have to unbolt the coolant neck at the block to access the thermostat. After replacing, you have to refill/bleed the coolant system.
This should happen automatically. Are you losing coolant, is the cooling system leaking somewhere? Have you just changed the coolant? Unless there is a leak, the system should purge by itself.

There is a schrader valve on the fuel rail that will allow you to blled the system. This is not normally necessary as the air will be pushed out by the fuel pressure.
On the right of the radiator or tlright in front of the intake filter tube there is black container with a cap, you add it there. Remember you must bleed the system

The thermostat should have a air bleed valve built in and the air bleed valve should be facing straight up.
You are most likely low on coolant. Bleed the cooling system after you add coolant to get any air out......
In answer to your question the coolant temperature sensor on a 2000 Pontiac grand am with a 3.4L engine, is located on the rear of the engine above the flywheel. It is located just behind the what I believe is the alternator.
