REPAIR PROCEDURE 1. From above the engine, set a long-handled, boxed- end wrench on the drive belt auto-tensioner. Slowly turn the wrench counterclockwise, then remove the drive belt. NOTE: On vehicles without A/C, the drive belt will be reused. 2. Insert a pulley holder (see REQUIRED SPECIAL TOOLS) into one of the holes in the water pump pulley at the 12 o’clock position. The tool holds the pulley so you can loosen or tighten the pulley bolts. 3. Remove the water pump pulley (three bolts). 4. Remove the pivot bolt from the drive belt auto- tensioner. NOTE: In rare cases, the pivot bolt may be broken. If this has happened, remove the auto-tensioner, then remove the shank of the pivot bolt with Vise Grips or by drilling it out. Do not try to repair the engine block using a TIME-SERT. If you can’t remove the shank of the pivot bolt, you would need DPSM approval to install an engine short block assembly.
