Evaporator, Removing And Installing: Installing
WARNING: This page is about a different car, the 2024 Audi SQ7, 2024 Audi Q7, 2023 Audi SQ7, and 2023 Audi Q7. However, it is still accessible from the selected car via links, so may be relevant.
Install in the reverse order of removal while noting the following:
- If the evaporator is replaced, the amount of refrigerant oil found in the removed evaporator must be added to the new evaporator. Refer to Refrigerant Circuit Components, Replacing or COMPONENTS, REPLACING .
TIP
- Foam seals which have not yet adapted to the sealing surfaces of the air intake housing are present on new evaporator. Therefore these seals must be pushed in with more force.
- If the Rear Fresh Air Blower -V80- and the evaporator are replaced at the same time, first install the Rear Fresh Air Blower -V80- on the air intake housing, then insert the evaporator.
-- Check on the evaporator -B- and attached foam seals -A, C, E, F, G, H and J- for damage and correct seating.
-- Check foam seals -D- attached to the refrigerant lines for damage and proper adhesion.
-- Check the contact surface all around the bevel on the air intake housing lower section for damage.
-- Check both connections at the refrigerant lines to the evaporator for contamination and damage.
