6. Remove the screw from the A/C line clamp (A) next to the steering rack.




7. Disconnect the rear A/C suction line (A) and receiver line (B) at the rear evaporator connections.
8. Free the rear A/C lines from the bracket above the steering gearbox.
9. Remove the rear A/C lines (receiver line, then suction line) from the top of the engine compartment. If necessary, bend the rear A/C lines as needed for removal.

NOTE: Be careful not to bend or snag the brake lines, wire harness, or other components when removing the rear A/C lines.

Installation

NOTE:
- Use care not to bend the replacement A/C lines during installation.
- Be careful not to bend or snag the brake lines, wire harness, or other components when installing the replacement A/C lines,

1. Route the lower replacement rear A/C lines (suction line, then receiver line) from the top of the engine compartment down to the rear evaporator connections. Do not connect the lines yet.




2. Route the upper replacement A/C lines along the engine compartment bulkhead, and loosely connect the upper lines (A) to the lower lines (B). Do not tighten the connections yet.




3. Install the A/C line clamp (A) on the lower replacement A/C line. Slide the bracket onto its A/C line bracket (B), but do not install the screw yet.
