Install in the reverse order of removal while noting 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 or COMPONENTS, REPLACING .

-- Replace the O-rings -E-. Refer to REFRIGERANT CIRCUIT SEALS .

-- If equipped, check the alignment pin -D- for damage and correct seating.

-- Install the refrigerant receiver -B- on the heat exchanger -C-.

-- Install the bolt -A-.

-- Replace the O-rings -3-. Refer to REFRIGERANT CIRCUIT SEALS .

-- If equipped, check the alignment pins -4- on the refrigerant lines for damage and correct seating.

-- Check the routing after securing refrigerant lines. They must be inserted in their brackets and must not come into 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 (Refrigerant R134a Servicing, Refrigerant Circuit, Working with A/C Service Station) or Working with A/C Service Station (1 Of 2) / Working with A/C Service Station (2 Of 2) .

-- Switch the ignition on.

-- Initiate the basic setting of the A/C system using the Thermal Management Control Module -J1024- and activate the electric valves using the routine Stop routine refrigerant circuit filling/flushing  in the Vehicle Diagnostic Tester.

-- Operate the A/C system after charging the refrigerant circuit. Refer to A/C SYSTEM, STARTING AFTER CHARGING REFRIGERANT CIRCUIT, VEHICLES WITH HIGH-VOLTAGE SYSTEM .
