Removal Procedure

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

Important: This engine was designed for starter motor mounting without shims. However, if single or double shims have been added to correct a noise or engagement condition, reinstall the shims in their original location to ensure proper pinion-to-flywheel engagement.
