Back Window Glass: Service and Repair

Special Tool(s)

REMOVAL







1. Disconnect the heated back window electrical connector.
2. Remove the rear window wiper pivot arm (wagon only).
3. Remove the rear hi-mount lamp (wagon only).
4. Remove the interior trim necessary to access the inside edge of the back window glass.







5. Use Interior Auto Glass Cut-Out Knife Kit 164-R2450 or equivalent to cut the urethane sealant; remove the back window glass.

WARNING: TO PREVENT GLASS SPLINTERS FROM ENTERING EYES OR CUTTING HANDS, WEAR SAFETY GLASSES AND HEAVY GLOVES WHEN CUTTING GLASS FROM THE VEHICLE.

NOTE: Lubricate the urethane sealant where it meets the glass with EC7784 lubricant or equivalent (10:1 ratio of water to soap) to aid the Interior Auto Glass Cut-Out Knife Kit 164-R2450 when cutting the urethane sealant.







6. Trim the remaining urethane on the pinch weld to the specified thickness.
- Apply Urethane Metal Primer (part of E0AZ-19562-A), or equivalent meeting Ford specification WSB-M2G234-C using the supplied wool applicator to any exposed metal on the pinch weld.
- Add Urethane Sealant (part of E0AZ-19562-A) or equivalent meeting Ford specification WSB-M2G316-B to bring the remaining urethane sealant to the specified thickness.
- If reusing the back window glass, clean off all of the old urethane sealant with an alcohol-free glass cleaner.

INSTALLATION







1. Dry set the back window glass.
- Position the back window glass in the pinch weld.
- Align the back window glass from the bottom center point of the glass out to the two spacers at the bottom of the pinch weld.
- Align the gap of the back window glass at the top and sides of the back window glass edge to pinch weld edge.
- Mark the back window glass and the body when aligned.
- Remove the back window glass from the pinch weld and clean the back window glass inside the perimeter with an alcohol-free cleaner and wipe the edge of the glass with a clean cloth.

NOTE: Keep glass and body surfaces free of dirt, water, and oil. Do not touch coated surfaces with your hands.







2. Install the (A) back window glass moulding on the (B) back window glass perimeter.







3. Apply Urethane Glass Prep (part of E0AZ-19562-A) or equivalent meeting Ford specification WSB-M5B280-C, then repeat the application.
- Apply Urethane Glass Prep on the back window glass directly inside the back window glass moulding on the blackout ceramic coating.
- Immediately wipe off the Urethane Glass Prep.
- Repeat the Urethane Glass Prep application.

NOTE: Immediately wipe off the urethane glass prep after application because it flash dries.







4. Apply Urethane Glass Primer (part of E0AZ-19562-A) or equivalent meeting Ford specification WSB-M2G314-B.
- Apply Urethane Glass Primer around the entire outer edge of the inside of the back window glass, directly inside the back window glass moulding.
- Allow 10 minutes drying time.

WARNING: IF PRIMER GETS ON YOUR HANDS, REMOVE IT IMMEDIATELY.

CAUTION: Do not apply the urethane glass primer inside of the blackout ceramic coating. The primer will permanently discolor the back window glass.







5. Install Norton Foam Sealants 565 Black Foam Tape or equivalent meeting Ford specification ESB-M3G77-A to the pinch weld.
- Start at the bottom of the pinch weld and install the tape all the way around inside the pinch weld perimeter.







6. Cut the nozzle of the urethane sealant canister to specification.







7. Apply a bead of Urethane Sealant (part of E0AZ-19562-A) or equivalent meeting Ford specification WSB-M2G316-B.
- Ensure that the bead of urethane sealant is smooth and even. If necessary, reshape the bead with a suitable tool, taking care not to trap air in the bead.

CAUTION
- Use only Urethane Sealant (part of E0AZ-19562-A), or equivalent meeting Ford specification WSB-M2G316-B to service water and air leaks of the urethane sealant.
- After replacing the urethane installed glass, the vehicle should not be driven until the urethane has cured. The curing times at temperatures above 13°C (55°F) and relative humidity above 50% curing time is 12-24 hours (decreasing at higher temperatures and lower humidities). Refer to the detailed instructions provided by the manufacturer in the kit. Inadequate curing of the urethane may adversely affect the strength of the urethane sealant bond.







8. Using the alignment marks, install the back window glass.

CAUTION: Open the windows to prevent the back window glass from being pushed out by air pressure if a door is closed.

NOTE: Ensure that the Urethane Metal Primer is clean and dry.

9. After the urethane sealant has cured, check for water leaks and add urethane sealant where needed.

CAUTION
- Use only Urethane Sealant (part of E0AZ-19562-A), or equivalent meeting Ford specification WSB-M2G316-B to service water and air leaks of the urethane sealant.
- After replacing the urethane installed glass, the vehicle should not be driven until the urethane has cured. The curing times at temperatures above 13°C (55°F) and relative humidity above 50% curing time is 12-24 hours (decreasing at higher temperatures and lower humidities).
