REFRIGERANT LINES, DISCONNECTING AND CONNECTING AT CONDENSER, Vehicles with 2.0L, 3.0L and 3.2L: Installing
Installation is done is reverse order, observe the following:
-- Clean the refrigerant line connections on the condenser and on the refrigerant lines and check for damage.
-- Replace the O-rings -C-. Allocate correct version.
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).
-- Coat the O-ring seals lightly with refrigerant oil before installing. Refer to REFRIGERANT CIRCUIT SEALS .
-- 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 the refrigerant circuit and fill it. Refer to USING SERVICE STATION . For additional information, refer to OVERVIEW - REFRIGERANT CIRCUIT, NOT OPENING THE REFRIGERANT CIRCUIT, VEHICLES WITHOUT HIGH VOLTAGE SYSTEM and OVERVIEW - REFRIGERANT CIRCUIT, OPENING THE REFRIGERANT CIRCUIT, VEHICLES WITHOUT HIGH VOLTAGE SYSTEM (Refrigerant R134a, Servicing; Refrigerant Circuit, Using Service Station).
-- 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 .
Observe the information regarding operating the A/C system after filling. Refer to A/C SYSTEM, OPERATING AFTER CHARGING , (Refrigerant R134a, Servicing; A/C System, General Information). After charging the A/C system before activating the A/C system.
