Is the evaporator core separately serviceable, and How to service it on Mercury Grand Marquis?

A replacement of the combination between evaporator core and housing assembly forms the necessary procedure. The suction accumulator requires replacement only in cases where contamination appears from failed A/C compressors or when the suction accumulator shows signs of damage. A leak test should occur before removing the evaporator core from the vehicle when such a leak is suspected. Service of the evaporator core begins with removing the housing before moving components from the old housing to a new housing for installation.

How to service and repair the evaporator core on Mercury Cougar?

The first task for servicing or repairing the evaporator core requires removal of the heater/evaporator core housing before disassembling the blower motor/evaporator housing and heater/evaporator housing through bolt removal and separation of rubber seal and nut securing the cover. First remove the evaporator by disconnecting the housing components after unclipping the vacuum hose. New O-rings treated with refrigerant oil must be used during installation and gaskets should follow the original positioning of the old evaporator. The installer should execute removal procedures in reverse order to set up the new evaporator core by handling it with PAG Compressor Oil YN-12-C or an equivalent product which satisfies Ford specification WSH-M1C231-B. Evacuate the A/C system and perform its recharging before verifying normal air conditioning system functionality.
