This tip is for all of you that have the 2.4 motor. If you get a performance crank pulley, it is best to have a shop do it. For those of you that wish to do it yourself. Start by getting the torque specks for it from GM, I will not give them to you.

1. Remove and jack up the front left side of the car.

2. Remove the inter black plastic wheel well covering or get it loose so it hanks from the top.

3. Remove the old serpentine belt.

4. Remove the old crank pulley.

5. Put in the new performance crank pulley and make sure you torque it to the right specks, if you don't then the engine will vibrate.

6. Now put the new belt that comes with the new pulley on and then put everything back the way you took it off.
