How to replace a Serpentine Belt Tensioner Pulley?
1.Materials Needed & Secure Vehicle
- Replacement idler pulley
- Socket set and ratchet
- Torque wrench
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.
2.Remove the Drive Belt
To remove the drive belt, first, release the tension to the belt. If your idler pulley attaches to the alternator, you will have to remove the bolt attaching the pulley to the alternator and push the entire alternator down to relieve the tension on the belt. If your pulley attaches to the engine block, then loosen the bolt attaching it to the engine block and push the pulley back to release the drive belt.
3.Remove the Old Pulley
With the Belt Pulley set out of the way, remove the retaining bolt and pull the pulley out. Keep the pulley and any gaskets or hardware that come off with the pulley. You will need to install the new pulley with this hardware in the exact same order.
4.Install the New Pulley
Compare the new pulley with the old to confirm it is a proper replacement. Assemble and install the new pulley with the appropriate hardware. Use the existing hardware from the old pulley if the new pulley doesn’t come with bolts and gaskets. Make sure you are assembling and installing the new pulley and hardware in the same order as the old pulley and hardware. Once the pulley and hardware are in place, hand tightens the retaining bolt.
5.Torque the Pulley & Replace the Drive Belt
Using a torque wrench (and a socket to keep the pulley from spinning if needed), torque the pulley bolt to 40 ft/lb. Set the wrench to 40 ft/lb and apply pressure to the bolt with the wrench until it clicks and you know you’ve hit the required torque. Replace any covers or plastic shields you may have removed to access the belt. Reinstall the negative battery cable.
