Removal

 WARNING: Wear eye and ear protection when servicing a vehicle. Failure to follow this instruction may result in serious personal injury.

 WARNING: Wear protective gloves when handling components or parts that have pointed or sharp edges. Failure to follow this instruction may result in serious personal injury.

NOTE: The rear roof applique will be damaged during the removal process. Install a new rear roof applique.

  1. Remove the glass roof panel. For additional information, refer to Section 501-11 .
  1. Using a suitable prying tool, pry up on the corners of the moulding to gain access to the adhesive.
  1. NOTE: Lubricate the urethane adhesive with water to aid the Deluxe Windshield Removal Tool when cutting the urethane adhesive.

    Using the Deluxe Windshield Removal Tool, begin cutting from either end towards the middle of the car. For additional information on the urethane adhesive path, refer to the illustration.
  1. Rotate the moulding up and forward while moving toward the interior of the car. Bend the moulding as necessary to gain access to the adhesive.
  1. Remove the moulding and discard.

Installation

 WARNING: Repair any corrosion found on the pinch weld. The pinch weld is a structural component of the vehicle. Corrosion left unrepaired may reduce the structural integrity of the vehicle. Failure to follow this instruction may result in serious injury to vehicle occupant(s).

NOTICE: The entire installation procedure requires the aid of an assistant. Failure to follow this direction may result in damage to the components.

NOTICE: The urethane adhesive has a 10-minute skin time. The entire installation process MUST be completed in no more than 10 minutes (L-shaped bead, applique bead, halo bead and all components installed). Failure to complete the installation process in the allotted time may result in a water leak, which may cause damage to the interior components.

  1. NOTE: Avoid scratching the pinch weld. Repair all minor scratches or exposed metal on the pinch weld following manufacturer's instructions. Use the same brand pinch weld primer, glass primer and urethane adhesive.

    NOTE: To make sure the new urethane adhesive bonds correctly to the original equipment urethane adhesive, the roof glass panel and appliques must be installed within 2 hours of trimming the original urethane adhesive bead.

    Using an appropriate tool, trim the urethane adhesive leaving a 1 mm to 2 mm (0.04 in to 0.08 in) base of original equipment urethane on the pinch weld and on the mating surface of the front roof glass applique.
  1. Using a clean shop towel, brush or oil-free compressed air, clean the pinch weld area around the existing urethane. Remove any foreign material or water that may have entered during removal.
  1. NOTE: The urethane adhesive bead needs to be 5 mm (0.3 in) wide and 7 mm (0.28 in) tall.

    Cut the urethane adhesive applicator tip to specification.
  1. NOTE: Use either a high-ratio, electric or battery-operated caulk gun that will apply the urethane with less effort and a continuous bead. Make sure there are no gaps in the bead.

    Apply L-shaped beads of urethane to both corners of the roof glass moulding mating surface.
  1. Apply the urethane adhesive to the roof glass applique. Follow the pattern as shown.
  1. Apply the urethane adhesive to the roof glass panel. Follow the pattern as shown.
  1. NOTE: The roof glass applique has a locator pin to make sure of proper fore and aft alignment. The applique must be centered side to side.

    Install the glass roof applique.
  1. NOTE: Before positioning the roof glass panel, open vehicle windows to prevent the air pressure of closing doors from affecting the adhesive bond.

    Carefully install the roof glass panel.
