Alan Calder, here is a good guide. The service manual says “DRIVE BELT REPLACEMENT Removal Procedure
- Raise and support the vehicle. Refer to LIFTING AND JACKING THE VEHICLE in General Information.
- Remove the front fender liner. Refer to FRONT FENDER LINER REPLACEMENT .
- Rotate the drive belt tensioner counterclockwise to release the spring tension.
- Remove the drive belt.
