Evaporator Core













Removal and Installation

NOTICE: Motorcraft(R) Electric A/C Compressor Oil only must be used as a refrigerant system lubricant for hybrid vehicles. Addition of any oil other than Motorcraft(R) Electric A/C Compressor Oil to the hybrid vehicle refrigerant system will damage the electric Air Conditioning (A/C) compressor and contaminate the refrigerant system. Refer to the Refrigerant Oil Adding procedure in Climate Control System - General Information and Diagnostics Refrigerant Oil Adding.

NOTICE: Use only the Air Conditioning (A/C) refrigerant compressor oil specified for this vehicle configuration. Use of any A/C refrigerant compressor oil other than what is specified will contaminate and damage the A/C system.

NOTE: If an evaporator core leak is suspected, the evaporator core must be leak tested before it is removed from the vehicle.
