Front Quarter Window Glass: 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).

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: Touching the adhesive surface impairs rebonding.

NOTE: Make sure the mating surfaces are clean and free of foreign material.
- Using a utility knife, trim the urethane adhesive leaving a 1-2 mm (0.04-0.08 in) base of original equipment urethane adhesive on the pinch weld.
- Using a soft brush or vacuum, remove any foreign material or dirt from the pinch weld.
