- Disconnect the battery. Refer to
Battery Negative Cable Disconnection and Connection.
- Lower the rear compartment partition (1).
- Place a protective cover over the rear compartment interior and the adjacent body panels.
- Remove the side compartment trim cover. Refer to
Rear Compartment Side Trim Replacement - Left Side or to
Rear Compartment Side Trim Replacement - Right Side.
- Locate the hydraulic pump beneath the carpet in the storage compartment on the driver side of the rear compartment.
- Turn the hydraulic pump bypass valve (1) counterclockwise until the valve stops.
- Support the rear compartment lid.
- Remove the 3 electrical connectors (1) from the hydraulic pump bracket (2).
- Remove the 2 electrical connectors (1) from the hydraulic pump bracket (2).
- Disconnect the 3 electrical connectors (1) from the folding top control module.
- Remove the bolts (1) from the hydraulic pump bracket.
- 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.
- Remove the hydraulic cylinder from the mounting location. Do NOT remove the hoses from the cylinder at this time. Refer to the following procedures:
- Remove the reservoir filler plug (1).
- Remove the bolts (1) from the pump manifold plate.
- Disengage the 4 large cylinder hoses (41,42,43,44) by pulling straight up on the hoses.
- Carefully lift up on the manifold plate (1).
- 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.
- 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.
- Push the hose back through the manifold plate.
- Remove the hose retaining ring (1).
- Remove the hose (1) from the manifold plate (2).
- Push the manifold end of the new hose (1) through the manifold plate (2).
- Using the
BO-47666 , install a new hose-retaining ring onto the hoses.
- Push the assembly cone (2) over the end of the hose (1) until the cone is fully seated.
- Install the retaining ring (2) onto the assembly cone (1).
- Using the
BO-47666 (2), push the retaining ring (1) into place.
- Remove the assembly cone (1).
- Repeat the replacement procedure for the second hose.
- Install a new O-ring (1) on each cylinder hose that you removed from the pump manifold.
- 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.
- Align the cylinder hoses into each port and push down until the hoses are seated properly in the hydraulic pump manifold.
- Install the manifold plate bolts (1). Do NOT tighten.
Notice: Refer to Fastener Notice in the Preface section.
- 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.
- 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.
- Depending on the hose set, you may have to remove and replace the following components:
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 .
- Use a small flat-bladed tool to release the retainer clip (1) from one of the cylinder hoses.
- 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.
- Remove the cylinder hose (1). Use a clean shop towel to control any hydraulic fluid leakage.
- Remove the cylinder hose O-ring (1) from the cylinder.
- Install a new O-ring (1) onto the cylinder hose (2).
- Install the hose into the cylinder port (3). Press straight down on the hose until the hose is fully seated in the cylinder.
- Install a new cylinder hose retainer clip (1). Inspect the retainer clip to ensure that the clip is fully seated around the hose (2).
- Repeat the replacement procedure for the second hose.
- Install the appropriate hydraulic cylinder to the mounting location. Refer to the following procedures:
- Install the reservoir filler plug (1).
- Position the hydraulic pump to the correct mounting location.
- 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).
- Connect the 3 electrical connectors (1) to the folding top control module.
- Install the 2 electrical connectors (1) to the hydraulic pump bracket (2).
- Install the 3 electrical connectors (1) to the hydraulic pump bracket (2).
- Install the side compartment trim. Refer to
Rear Compartment Side Trim Replacement - Left Side or to
Rear Compartment Side Trim Replacement - Right Side.
- Remove the protective covering.
- Turn the pump bypass valve (1) clockwise until the valve stops.
- Raise the rear compartment partition (1).
- Connect the battery. Refer to
Battery Negative Cable Disconnection and Connection.
- Remove the rear compartment lid support.
- Close the rear compartment.
- Bleed the hydraulic system. Refer to
Folding Top Hydraulic System Bleeding Procedure .
- Inspect the hydraulic system for fluid leaks.
- Inspect the hydraulic system fluid level and add fluid as needed. Refer to
Folding Top Fluid Addition
- Inspect the folding top for proper operation. Refer to
Power Folding Top Description and Operation .
