Refrigerant Lines, Disconnecting And Connecting From Condenser

NOTE:

Different versions of the condenser are available depending on the vehicle version.

5 cylinder vehicles have a condenser -A- that has an additional double pipe -C- bolted on to the condenser -A-. The double pipe -C- is supplied with the condenser. If it necessary to loosen the double pipe -C- from the condenser -A- use the same tightening specification for the screws on the connections as for the screws on the refrigerant lines -D- and -E-.

Installation is the reverse of removal, noting the following:

NOTE:

Coat the O-ring seals lightly with refrigerant oil prior to installation. Refer to REFRIGERANT CIRCUIT O-RINGS .

Ensure O-ring seals -E- (different versions) are seated correctly in groove -arrow- on respective refrigerant line.

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

-- Replace O-rings -E-. Version.

-- Check fitting pin -G- (not installed at all connections) and connection -F- for damage and proper seating.

-- Tighten bolts -C-.

Tightening specification: Bolts on refrigerant line connection on condenser - 12 Nm.

-- Discharge and fill the refrigerant circuit. Refer to Description and Operation (A/C Service Station).

-- Install remaining components.

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

NOTE:

Note the information regarding operating the A/C system after filling. Refer to Description and Operation (A/C Service Station).
