Fluid Reservoir
Fluid Reservoir
Does not apply to condensers, which have an attached reservoir.
• Fluid reservoir - C - and condenser - B - are available in different versions (one or two mounting bolts - D - and - E - for fluid reservoir). Refer to Electronic Parts Catalog (ETKA).
• If the reservoir is secured by two bolts, the bolt - E - can be replaced on a front end module - A - that does not have an opening - F - (when the opening will be introduced is still open) either with the condenser removed or make a 14 mm hole in the front end module. 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). Adjustment of oil quantity depends on nature of complaint.
• If for example the fluid reservoir was damaged due to a vehicle accident (no refrigerant leaked out, no moisture and no dirt penetrated into refrigerant circuit), let refrigerant oil flow out of the removed fluid reservoir and add the drained quantity of refrigerant oil plus 10 cm3 of fresh refrigerant oil to the refrigerant circuit (e.g. condenser), this services the refrigerant circuit without extensive repair work.
• 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. If the condenser has an integrated reservoir, replace the dryer cartridge. Refer to => [ Dryer Cartridge, Denso Condenser ] Dryer Cartridge, Denso Condenser or => [ Dryer Cartridge, Modine Condenser ] Dryer Cartridge, Modine Condenser.
Removing
- Discharge the refrigerant circuit.
- Remove front bumper.
- Remove bolts - D - and - E - (bolt - E - not always present), tightening specification: 10 Nm.
- Remove bolts - B - (tightening specification: 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. As a running change in MY 2006, the mounting was changed from a metal bracket attached by screws to a plastic bracket held in place by expansion clips.
• Fluid reservoir - C - and condenser - B - is available in different versions. At beginning of production, fluid reservoirs were installed on which only one O-ring seal - A - and - B - each were present on fluid reservoir connections. Refer to Electronic Parts Catalog (ETKA).
• In MY 2005 as a running change, reservoirs, that had two seals on the connections, were installed. Each a seal - B - and an O-ring - C -. Refer to Electronic Parts Catalog (ETKA).
Installation is carried out in the reverse order while noting the following:
Before installing fluid reservoir, refer to=> Refrigerant R134a Servicing Removal and Installation.
- Clean the contact surface on the condenser - C -
- Replace O-ring seals - A - and - B -. Refer to=> [ Refrigerant Circuit O-rings ] Refrigerant Circuit O-Rings and Electronic Parts Catalog (ETKA).
- Replace seals - B - and O-ring seals - C -. Refer to Electronic Parts Catalog (ETKA).
- Place fluid reservoir - A - on condenser and tighten bolts.
• Coat the O-ring seals lightly with refrigerant oil prior to installation. Refer to=> [ Refrigerant Circuit O-rings ] Refrigerant Circuit O-Rings.
• Check O-ring seals for correct allocation and proper seating in grooves of respective mount.
• Hold the reservoir closed as long as possible. Remove the cap just before installing. 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 re-charge refrigerant circuit.
- Operate the A/C system after filling the refrigerant circuit. Refer to=> [ A/C System, Operating After Filling Refrigerant Circuit ] Procedures.
• Note the information regarding operating the A/C system after filling.
