The coolant bleeder valve should be on the front passenger side of the engine. It will be on one of the metal hoses. The bleeder valve on the 3400 V6 engine is located on a black stem where the water pump connects to the engine block.
It should be a bleeder screw connected to the cooling system, it might be two.If you find it,you should open one at a time.Pour coolant into the system slowly,until coolant start coming out of the bleeder screw and then close it . DO it to the second screw too.Now if you do not have the bleeder screws.Pour coolant into your system slowly and squeeze the top hose until no bubbles come out and the coolant level should go down at this time and then pour alittle more in there
Lower corner rad, driver side. Looks like a plastic key.
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.
The bleeder screw for the coolant system is on top of the motor, tword right side of the intake manifold. It should look like a nut with a flat head screw in it on a piece that goes into the motor.
sensor is located on coolant housing at engine front
Use the bleeder valve to bleed the system.
The coolant drain on a 2003 Pontiac Grand Am is located on the bottom of the radiator on the right side. It allows coolant to be quickly removed during maintenance and flushes.
On the coolant overflow bottle that in on the passenger side of the engine.
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.
If there are no bleeder valves, simply remove the radiator cap, fill the radiator to the top, start the engine. With the engine running keep the coolant level full and watch for air bubbles. After the engine has reached full operating temp and you no longer see any air bubbles escaping shut it off and replace the cap. If there are bleeder valves use them to remove trapped air after the engine is running. Be careful as not to get burned by hot coolant.
looks like there is a coolant bleed valve on top of the water pump casting on top of a 2 inch high PC of metal tubing one small needle valve with a 6mm hex nut
