Repair

NOTE: If servicing the rear window glass, this procedure is considered a major service repair. For Ford warranty coverage, the vehicle must be returned to the Multimatic vehicle assembly and repair facility.

NOTE: If any of the following conditions exist, the fixed glass must be discarded. A new fixed glass is required.

The fixed glass is the windshield glass and equipped with adhesive mouldings.

NOTE: Some interior trim, exterior trim and/or components may require removal based on the tools and removal method used.

NOTE: When replacing the windshield the front fenders must be removed.

NOTE: In some instances repair methods may be combined to achieve the best results.

Choose the best repair method for the type of glass being replaced.
1. Cold knife method - uses the cold knife to cut the urethane from the outside of a vehicle provided the blade can reach the bead. Use the General Equipment: Cold Knife
2. Power tool method - uses various power tools from inside the vehicle using a cutting or paddle type blade. Use the General Equipment: Power Fixed Glass Removal Tool
3. Piano wire method - uses the piano wire to cut the urethane from inside and outside of a vehicle using an assistant. Use the General Equipment: Glass Cut-Out Wire
When using the cold knife method, apply tape to protect the perimeter of the window opening from paint damage. Multiple layers of tape may be required.

NOTE: New or reused fixed glass must be installed within 2 hours of cutting the urethane adhesive. Exposed cut surfaces of urethane become oxidized and inactive beyond 2 hours, reducing the effectiveness of the repair bond.

NOTE: Use extreme care not to scratch the paint or primer or damage the fixed glass flange during glass removal.

NOTE: Take precautions to prevent damage to other components when cutting urethane.

NOTE: If any of the following conditions exist, the fixed glass must be discarded. A new fixed glass is required.
- The fixed glass is the windshield glass and equipped with adhesive mouldings.
NOTE: Fixed glass may have locating pins that vary in location. It may be necessary to cut these pins with a utility knife.

Remove the fixed glass. Use the General Equipment: Power Fixed Glass Removal Tool. Use the General Equipment: Cold Knife. Use the General Equipment: Knife

NOTE: New or reused fixed glass must be installed within 2 hours of cutting the urethane adhesive. Exposed cut surfaces of urethane become oxidized and inactive beyond 2 hours, reducing the effectiveness of the repair bond.

NOTE: Touching the adhesive surface impairs the rebonding.

NOTE: Make sure the mating surfaces are clean and free of foreign material.

Prep the fixed glass flange area to install the new or reused fixed glass.
1. Trim or shave down the original urethane adhesive on pinch weld flange and on glass (if reused) using a utility knife, leaving a 1 mm to 2 mm (0.04 in to 0.08 in) base on the parts, only when final installation is within 2 hours.
2. Remove any foreign material or dirt from the fixed glass flange using a soft brush or vacuum. Use the General Equipment: Vacuum Cleaner
NOTE: Minimize applying primer over areas with remaining urethane adhesive and observe a minimum flash time of 10 minutes.

Apply primer as necessary.
1. If the clear coat layer was damaged on the fixed glass flange apply primer to those areas only.

NOTE: Make sure the urethane bead is uniform to prevent air and water leaks.

NOTE: The fixed glass must be installed within 10 minutes of applying the urethane adhesive.

NOTE: Use a power caulk gun that applies the urethane adhesive with less effort and a continuous bead.

Apply a urethane adhesive bead.
1. Start and end at the original overlap points to prevent air and water leaks.
2. NOTE: Take care in applying urethane on vehicles without peripheral moldings as urethane expulsion could become an appearance issue.
  
  Apply a urethane adhesive bead 14 mm (0.551 in) high and 8 mm (0.314 in) wide on top of the existing trimmed urethane adhesive bead on the fixed glass flange. Use the General Equipment: Power Caulk Gun

WARNING: Do not drive vehicle until the urethane adhesive seal has cured. Follow urethane adhesive manufacturer's curing directions. Inadequate or incorrect curing of the urethane adhesive seal will adversely affect glass retention. Failure to follow these instructions may result in serious injury to vehicle occupant(s).

Install the fixed glass to the vehicle.
1. Install the fixed glass, pressing firmly by hand to ensure a good bond.
2. Secure the fixed glass in the correct position with tape until the urethane adhesive has cured.
If necessary, remove excess uncured urethane adhesive from the interior and exterior surface of the fixed glass.
