-- Replace the O-rings -C-. For the correct version. Refer to Parts Information.

NOTE:

Follow the instructions for installing the O-rings. Refer to REFRIGERANT CIRCUIT SEALS .

Following attachment, check routing of refrigerant lines on condenser. They must be inserted in holders provided and not make contact with other components.

The refrigerant line -C- (from the condenser to the quick-release coupling on the refrigerant line with the inner heat exchanger) is secured by a clip -B- to the fender brace -A- from MY 2008. The fender brace -A- has a hole -D- (diameter 6.5 mm). If the fender brace -A- does not have hole -D- (or a refrigerant line -C- without a clip -B-), then secure the refrigerant line -C- to the fender brace -A- with a cable tie. Wrap the refrigerant line -C- on the contact surface with a piece of foam (to protect against damage).

-- Make sure the O-ring fits correctly inside the grooves -arrows- on each mount.

-- Check the fitting pin -A- (not installed on all connections) and refrigerant line connections -B, E and F- for damage and proper seating.

-- Tighten the bolts -D-.

• Tightening specification: 9 Nm

-- Install the cover on the lock carrier. Refer to FRONT BUMPER .

-- Evacuate and charge the refrigerant circuit. Refer to REFRIGERANT CIRCUIT (Refrigerant R134a Servicing, Refrigerant Circuit, Working with A/C Service Station) or REFRIGERANT CIRCUIT .

-- Install the remaining removed components.

-- Turn on the ignition.

-- Check the DTC memory for the Climatronic Control Module -- display and control head and erase any displayed malfunctions, if necessary using the Vehicle Diagnostic Tester in the "Guided Fault Finding" function.

-- Operate the A/C system after filling the refrigerant circuit. Refer to A/C SYSTEM, STARTING OPERATION AFTER FILLING REFRIGERANT CIRCUIT .
