Preparatory work

Draining the air conditioning (A/C) system and removing components

WARNING: Follow the safety instructions for work on air conditioning systems. See: Refrigerant, safety regulations.

Read the instructions for slow and fast leaks acc. to: AC-system, refilling.

CAUTION: Always use new O-rings lubricated with compressor oil.

NOTE: Plug the pipes and connections when working on the climate control system.

Drain the refrigerant from the air conditioning (A/C) system. See: Refrigerant, draining.

Remove:
- right-hand front headlamp.
- the bumper shell.

Remove:
- the front edge of the right-hand fender liner

Installation

NOTE: For tightening torques, see: Tightening torque. Mechanical Specifications

Installing receiver

Fill the recommended volume of compressor oil. See: AC-system, refilling.

NOTE: Install the receiver within 5-10 minutes of the plugs having been removed. This prevents the absorbent material absorbing moisture from the air.

Install:

Finishing

Checking the function and leak tracing

Vacuum pump the air conditioning (A/C) system. See: Vacuum pumping. Fill the air conditioning (A/C) system with refrigerant. See: Refrigerant, filling. Leak trace the air conditioning (A/C) system. See: Leak detection, tracer agent or: Leak tracing, electronic leak detector.

Installing components and checking performance

Install:
- the bumper cover.
- right-hand front headlamp.

Carry out a performance test on the climate control unit. See: Climate control system, check.
