Receiver Dryer: Service and Repair

Fluid Reservoir

• Fluid reservoir - C - and condenser - B - are available in different versions (one or two mounting bolts - D - and - E - for fluid reservoir)





• The reservoir is attached with two screws. Screw - E - on a front end module - A - without an opening - F - (the introduction of the opening is still open), or make a hole if the condenser is being replaced (diameter approximately 14 mm). Be careful not to damage the radiator and/or the condenser when drilling.

• The removed reservoir contains refrigerant oil that must be returned to the refrigerant circuit (with the new reservoir). Refer to => Refrigerant R134a Servicing. Adjustment of oil quantity depends on nature of complaint.

• If the reservoir is damaged, for example, due to a crash (not refrigerant has leaked out and no dirt or moisture has gotten into the refrigerant circuit), then drain the refrigerant out of the removed reservoir and fill the circuit plus 10 cm3 so that the refrigerant circuit can be serviced.

• If an undefined amount of refrigerant oil escaped or dirt and moisture entered the system, refrigerant circuit must be cleaned.

• The reservoir may be attached to or integrated in the condenser, depending on the version of the condenser. Replace the dryer cartridge on a condenser that has an integrated reservoir, refer to => [ Dryer Cartridge ] .

Removing

- Remove front bumper.

- Remove bolts - D - and - E - (bolt - E - not always present), tightening torque 10 Nm.





- Remove bolts - B - (tightening torque 10 Nm).





- Slide bracket - C - out of mount of condenser - E - downward - arrows -.

- Remove the reservoir - D - from the condenser - E - - arrow -.

- Seal open connections (against dirt and moisture penetration).

Installing

• There are different versions of the condenser and bracket - C - depending on the production time period. The bracket was changed from a metal one to the plastic one in MY 2006. It is held on by clips.

• Fluid reservoir - C - and condenser - B - is available in different versions. Reservoirs with only one O-ring were being installed at the start of production - A - and - B -





• In MY 2005 as a running change, reservoirs, that had two seals on the connections, were installed. One seal - B - and one O-ring - C -.





Installation is carried out in the reverse order, when doing this note the following:

Before installing fluid reservoir, refer to => Refrigerant
R134a Servicing.

- Clean the contact surface on the condenser - C -.





- Replace O-ring seals.

- Replace seals - B - and O-ring seals - C -.





- Place fluid reservoir - A - on condenser and tighten bolts.

• Coat the O-ring with refrigerant oil before installing.

• Check O-ring seals for correct allocation and proper seating in grooves of respective mount.





• Keep the reservoir sealed as long as possible and remove the caps just before installing it. The reservoir has a dryer cartridge, which will absorb moisture if the reservoir is opened for a short time. This will make it then unusable.

- Evacuate and charge refrigerant circuit.

- Operate the A/C system after filling the refrigerant circuit.

• Note the information regarding operating the A/C system after filling.
