Refrigerant Receiver, Removing And Installing: Installing
Install in reverse order of removal and note the following:
- There is refrigerant oil in the removed heat exchanger and refrigerant receiver that must be redelivered to the refrigerant circuit, if one of the components is replaced. Refer to Refrigerant Circuit Components, Replacing (R134a) or COMPONENTS, REPLACING (R1234yf) .
-- Replace the O-rings -F, G-. Refer to REFRIGERANT CIRCUIT SEALS and the Parts Information for the correct version.
-- If equipped, check the alignment pin on the heater core -E- and on the refrigerant line -H- for damage and correct seating.
-- Install the refrigerant receiver -D-.
-- Insert the refrigerant line -C- and pay attention to the correct routing.
-- Install the bolts -A and B-.
-- Check the routing of the refrigerant lines after attaching. They must be inserted into the provided brackets and must not come in contact with other components.
-- Reinstall the rest of the removed components in the reverse order and reattach the loosened components.
-- Evacuate and fill the refrigerant circuit. Refer to Refrigerant Circuit (R134a) (Refrigerant R134a Servicing, Refrigerant Circuit, Working with A/C Service Station) or Working with A/C Service Station (R1234ya) (1 of 2) or Working with A/C Service Station (R1234yf) (2 of 2) .
-- Switch the ignition on.
-- Initiate the basic setting of the A/C system through the Thermal Management Control Module -J1024- and activate the power-controlled valves using one of the routines stored there. "Charge/flush the refrigerant circuit stop routine" using the Vehicle Diagnostic Tester in the "Guided Fault Finding" function.
-- Check the DTC memory of the Front A/C Display Control Head -E87- (and of the Thermal Management Control Module -J1024-) and erase any displayed malfunctions using the Vehicle Diagnostic Tester in the "Guided Fault Finding" function.
-- Start the A/C system after charging the refrigerant circuit. Refer to A/C SYSTEM, STARTING AFTER CHARGING REFRIGERANT CIRCUIT .
