Installation Procedure

WARNING: This page is about a different car, the 2002 GMC Savana Special, 2002 GMC Savana Camper Special, 2002 GMC Savana, and 2002 Chevrolet Chevy Express. However, it is still accessible from the selected car via links, so may be relevant.
  1. Install the bulb to the socket.
  2. Gently push in on the bulb and turn the bulb 1/4 turn clockwise.
  3. Install the lens to the lamp assembly.
    CAUTION: 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 to avoid damage to parts and systems.
  4. Install the screws in order to retain the lens to the lamp assembly.

    Tighten 

    Tighten the screws to 1.5 N.m (13 in lbs).
