Starter Replacement LT1

Removal Procedure

Important: This vehicle was designed for starter 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.

  1. Disconnect the negative battery cable. Refer to

    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.

    in General Information.
  2. Raise the vehicle. Suitably support the vehicle. Refer to Section 0A.

  1. Connect the the starter motor leads.
  2. Tighten

        • Tighten the starter solenoid BAT terminal nut to 10 N·m (89 lb in.). Refer to

    Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
