Evaporator
- Remove A/C unit. Refer to => [ Heating and A/C Unit ] Heating and A/C Unit.
- Disassembling A/C unit. Refer to => [ Heating and A/C Unit, Climatronic ] Heating and A/C Unit, Climatronic, Vehicles with Climatic, refer to => [ Heating and A/C Unit, Climatic ] Heating and A/C Unit, Climatic.
- Disassemble evaporator housing. Refer to => [ Evaporator Housing ] Evaporator Housing.
- Remove evaporator - A - from lower section of evaporator housing.
• Before inserting the evaporator, check condensation water drain and clean drain if necessary.
• Before inserting evaporator, clean evaporator housing and the evaporator if necessary.
- When inserting evaporator - A - into lower section of evaporator housing and when assembling both housing halves, make sure the seal - F - is not damaged.
- Check seal - F - (it must be glued all around) before inserting evaporator.
- Place bracket - C - and seal / insulation - B - onto connecting pipe of evaporator - D - and - E -.
- Insert evaporator - A - into lower section of evaporator housing as shown in the illustration.
• After assembling both housing halves, check seal / insulation -B- for correct seating at pass-through for both refrigerant lines -D- and -E-.
• Check seating of bracket - C - on both refrigerant lines - D - and - E - for correct seating.
• If heat protection insulation - B - is missing or not installed correctly, it can cause reduced performance of the A/C system (change of adjusted control characteristics of expansion valve due to radiant heat).
