12. Disconnect the 3 electrical connectors (1) from the folding top control module.



13. Remove the bolts (1) from the hydraulic pump bracket.
14. Lift the pump up and out of the storage compartment and set the pump on the protective covering.

Important: If you are replacing hose sets for more than one cylinder, complete the procedure for one cylinder before you begin with another.

15. Remove the hydraulic cylinder from the mounting location. Do NOT remove the hoses from the cylinder at this time. Refer to the following procedures:

•	Folding Top Header Latch Hydraulic Cylinder Replacement

•	Folding Top Storage Compartment Closeout Panel Hydraulic Cylinder Replacement - Front

•	Folding Top Cylinder Replacement

•	Folding Top Storage Compartment Panel Hydraulic Cylinder Replacement - Rear

•	Folding Top Compartment Lid Hydraulic Cylinder Replacement - Rear




16. Remove the reservoir filler plug (1).



17. Remove the bolts (1) from the pump manifold plate.



18. Disengage the 4 large cylinder hoses (41,42,43,44) by pulling straight up on the hoses.



19. Carefully lift up on the manifold plate (1).
20. Locate the pair of cylinder hoses that need replacement. Refer to Folding Top Hydraulic Cylinder Hose Identification .

Important: Remove the 2 hose connections one at a time. Repeat the following procedure for the second hose.

21. For each set of hoses being replaced, remove one hose by pulling straight up from the pump. Use a clean shop towel to control any hydraulic fluid leakage.
22. Push the hose back through the manifold plate.



23. Remove the hose retaining ring (1).



24. Remove the hose (1) from the manifold plate (2).



25. Push the manifold end of the new hose (1) through the manifold plate (2).



26. Using the BO-47666 , install a new hose-retaining ring onto the hoses.
27. Push the assembly cone (2) over the end of the hose (1) until the cone is fully seated.



28. Install the retaining ring (2) onto the assembly cone (1).



29. Using the BO-47666  (2), push the retaining ring (1) into place.



30. Remove the assembly cone (1).
31. Repeat the replacement procedure for the second hose.



32. Install a new O-ring (1) on each cylinder hose that you removed from the pump manifold.



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



35. Install the manifold plate bolts (1). Do NOT tighten.

Notice: Refer to Fastener Notice in the Preface section.




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

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

Important: Improper hose routing can lead to hose failure as a result of rubbing or pinching.

37. Route the new hose set to the cylinder in the same way as the set being replaced.

Important: Remove only one fastener at a time so that the amount of slack between fasteners can be exactly duplicated between the hose sets.

38. Depending on the hose set, you may have to remove and replace the following components:

•	The tie wraps

•	The P-clips

•	The wire loom

•	The conduit





Important: Remove the 2 hose connections one at a time. You will repeat this entire procedure for the second hose later. Refer to Folding Top Hydraulic Cylinder Hose Identification .

39. Use a small flat-bladed tool to release the retainer clip (1) from one of the cylinder hoses.



40. Remove the retainer clip (1).




Important: After you have removed the cylinder hose, do NOT move the cylinder rod. This will cause fluid to squirt out of the ports.

41. Remove the cylinder hose (1). Use a clean shop towel to control any hydraulic fluid leakage.



42. Remove the cylinder hose O-ring (1) from the cylinder.



43. Install a new O-ring (1) onto the cylinder hose (2).
44. Install the hose into the cylinder port (3). Press straight down on the hose until the hose is fully seated in the cylinder.



45. Install a new cylinder hose retainer clip (1). Inspect the retainer clip to ensure that the clip is fully seated around the hose (2).
46. Repeat the replacement procedure for the second hose.
47. Install the appropriate hydraulic cylinder to the mounting location. Refer to the following procedures:

•	Folding Top Header Latch Hydraulic Cylinder Replacement

•	Folding Top Storage Compartment Closeout Panel Hydraulic Cylinder Replacement - Front

•	Folding Top Cylinder Replacement

•	Folding Top Storage Compartment Panel Hydraulic Cylinder Replacement - Rear

•	Folding Top Compartment Lid Hydraulic Cylinder Replacement - Rear




48. Install the reservoir filler plug (1).



49. Position the hydraulic pump to the correct mounting location.
50. Apply LOCTITE™ Blue, GM P/N 12345382 (Canadian P/N 10953489) or equivalent to the bracket bolts (1).

Tighten
Tighten the bolts to 18 N·m (13 lb ft).




51. Connect the 3 electrical connectors (1) to the folding top control module.



52. Install the 2 electrical connectors (1) to the hydraulic pump bracket (2).



53. Install the 3 electrical connectors (1) to the hydraulic pump bracket (2).
54. Install the side compartment trim. Refer to Rear Compartment Side Trim Replacement - Left Side or to Rear Compartment Side Trim Replacement - Right Side in Body Rear End.
55. Remove the protective covering.



56. Turn the pump bypass valve (1) clockwise until the valve stops.



57. Raise the rear compartment partition (1).
58. Connect the battery. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.
59. Remove the rear compartment lid support.
60. Close the rear compartment.
61. Bleed the hydraulic system. Refer to Folding Top Hydraulic System Bleeding Procedure .
62. Inspect the hydraulic system for fluid leaks.
63. Inspect the hydraulic system fluid level and add fluid as needed. Refer to Folding Top Fluid Addition
64. Inspect the folding top for proper operation. Refer to Power Folding Top Description and Operation .
