Expansion Valve, Removing And Installing, GTE: Installing
Install in the reverse order of removal while noting the following:
-- Before installing, coat the new seals -1- with refrigerant oil on a sponge.
-- Push the new seal -1- on the connecting tubes -2-.
-- Inspect the refrigerant line for debris and damage.
-- Press the refrigerant pipe -2- into the expansion valve by hand.
-- Install the bolt -1- by hand and then tighten to the specified tightening specification.
The expansion valve is available in different versions (same housing but different control characteristic). Allocation. Refer to the Parts Information.
Pay attention that the seal on the evaporator connecting tube is seated correctly.
If the heat shield insulation -2- is missing or not installed correctly, it can cause reduced output of the A/C system (change of the set control characteristic due to radiant heat).
There is a risk of damaging the A/C compressor if the refrigerant circuit is empty.
- Never start the engine with the refrigerant circuit empty.
-- Charge the refrigerant circuit. Refer to REFRIGERANT CIRCUIT, CHARGING .
-- Perform the leak test on the closed line connections of the refrigerant circuit. Refer to LEAKS, FINDING .
