FOLDING TOP PUMP WITH MOTOR REPLACEMENT

REMOVAL PROCEDURE
1. Place the folding top in the up position.

CAUTION:
- Refer to Eye Protection Caution in Service Precautions.
- Refer to Folding Top Hydraulic Pressure Caution in Service Precautions.
- Refer to Servicing Electrical Components Caution in Service Precautions.

2. Open the rear compartment.
3. Disconnect the battery.
4. Place a protective covering over the rear compartment interior and the adjacent body panels.
5. Remove the right side compartment trim.
6. Support the rear compartment lid.
7. Disconnect the sunroof solenoid harness.




8. Turn the hydraulic pump bypass valve (1) counterclockwise until the valve stops.
9. Remove the push-in-pins that attach the control module to the pump bracket.
10. Remove the electrical connectors from the pump bracket and control module Sunroof Module Assembly Replacement (CF5) Sunroof Module Assembly Replacement (C3Y).
11. Remove the nuts (2) that attach the pump to the floor pan.




12. Remove the screws (1) from the pump (2) and manifold (3).

IMPORTANT: Rotate the pump motor outward to remove the bolts from the hydraulic line manifold.




13. Disengage the cylinder hoses (1) by pulling straight rearward on the manifold block and hoses (2). Use a clean shop towel to control any hydraulic fluid leakage.
14. Lift the pump upward to disconnect the electrical connector from the hydraulic pump motor.
15. Lift the pump up and out of the storage compartment and set the pump on the a protective cover. Use a clean covered surface to control any hydraulic fluid leakage.
16. Remove the reservoir filler plug (1).Empty the hydraulic fluid in to a suitable container, when replacing the pump motor.




17. Remove the screws (1) from the pump bracket (2).




18. Remove the O-ring (1) from each hose.

INSTALLATION PROCEDURE




1. Install the screws (1) to the hydraulic pump bracket (2) and the screws to the motor.

NOTE: Refer to Fastener Notice in Service Precautions.

Tighten the screws to 10 N.m (89 lb in)




2. Install a new O-ring (1) on each cylinder hose.
3. Install the pump to the storage compartment and set the pump on the a protective covering. Use a clean shop towel to control any hydraulic fluid leakage.




4. Align the manifold plate bolt holes to the holes on the new pump. This will ensure that the cylinder hoses are placed in the correct port.
5. Align the cylinder hoses into each port and push down until the hoses are seated properly in the hydraulic pump manifold.




6. Push down on the manifold plate (1) and verify that all of the cylinder hoses are seated properly.

NOTE: Refer to Fastener Notice in Service Precautions.

Tighten the bolts to 10 N.m (89 lb in)

Apply Loctite(R) Blue, GM P/N 12345382 (Canadian P/N 10953489) or equivalent to the bolts.

7. Connect the electrical connectors to the hydraulic pump.
8. Install the nuts that attach the pump to the floor pan.

Tighten the bolts to 18 N.m (13 lb ft).
9. Connect the sunroof solenoid harness.
10. Connect the electrical connectors to the control module.
11. Install the push-in-pins that attach the control module to the pump bracket.
12. Add fluid as needed.
13. Install the reservoir filler plug (1).
14. Install the side compartment trim.
15. Remove the protective covering.




16. Turn the pump bypass valve (1) clockwise until the valve stops.
17. Connect the battery.
18. Remove the rear compartment lid support.
19. Bleed the hydraulic system. Refer to Folding Top Hydraulic System Bleeding Procedure.
20. Inspect the hydraulic system for fluid leaks.
21. Inspect the hydraulic system fluid level and add fluid as needed.
22. Close the rear compartment.
23. Inspect the folding top for proper operation.
