1. Remove the serpentine belt: First, loosen the belt tensioner and remove the existing serpentine belt.
2. Install the idler pulley: Mount an idler pulley in place of the AC compressor. The idler pulley should align with the other pulleys in the serpentine belt path.
3. Re-route the serpentine belt: Start by placing the belt on the crankshaft pulley. Then, wrap the belt around the idler pulley and other pulleys in the original serpentine belt path, ensuring proper tension.
4. Adjust tensioner: Adjust the belt tensioner to achieve the proper tension specified in the vehicle's manual.
Please note that this method may not work for all vehicles and can affect the efficiency and performance of the engine's cooling system. Bypassing the AC compressor also means that you won't be able to use your vehicle's air conditioner.
It is generally recommended to use a pulley bolted engine or a specific bypass pulley kit designed for your vehicle model to ensure proper functionality and reliability when bypassing the AC compressor with a serpentine belt.
