Where is the idler pulley on a Pontiac Grand Prix?
The larger 3.5″ smooth supercharger idler pulley is located just above the crank shaft pulley (lowest & largest) and slightly closer to the front of the car. To remove the 3.5″ SC idler pulley, place the 15mm socket and long handled wrench on the pulley’s bolt.
How do you remove an idler pulley from a car?
Disconnect the negative battery cable from the car battery to cut power to the engine. Set the cable aside where it cannot make contact with anything metal. Step 2: Remove the drive belt. To remove the drive belt, first release the tension to the belt.
How do you remove a tensioner pulley on a Pontiac Grand Prix?
The pulley’s bolt is reverse threaded so to the left is tighten and to the right is loosen. After loosening the tensioner pulley’s bolt, it will come off with a large metal washer attached. The 3″ smooth tensioner pulley itself can be removed by gently rocking it while pulling it away from the engine.
Why is my idler pulley on my GTP not working?
A few days ago the serpentine or “accessory” belt in my 2001 Pontiac Grand Prix GTP tore itself apart after some spirited driving. While replacing the Serpentine Belt and the Supercharger Belt, I noticed that a tensioner pulley and an idler pulley didn’t spin easily due to their bearings being worn out.
When do you need to replace the idler pulley?
If it doesn’t, you probably need to replace the pulley. If you look at the belt when the car is running at idle, it moves quite smoothly along the system. When there is significant deterioration of pulley hardware, the belt moves from side to side. You will notice that it shakes or wobbles as it moves.
How can I tell if my idler pulley is frozen?
To confirm if your idler pulley is frozen, you have to slip the belt off the pulley. Before you start, make sure the engine is off and the keys are not in the ignition, just to make sure no one attempts to turn on the engine.
Why does my idler pulley make a rumbling noise?
This noise could also be as a result of idler pulley bearings gone bad. Bearings allow the pulley to rotate smoothly on its base. If this is the case, other noises like rumbling and cluttering may also be heard.
Where does the energy from an idler pulley come from?
Energy produced by the engine comes as a result of linear motion (up and down movements of pistons) but it has to be converted into rotary motion. It is drive belts like the one on an idler pulley which transmit rotary motion from the engine crankshaft into power which can be utilized by these components.
