Thermostatic Expansion Valve Manifold and Tube Assembly













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.

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.

All vehicles

1. Recover the refrigerant.

3.5L vehicles

2. Remove the lower cowl panel grille.

Non-hybrid vehicles

3. Detach the wire harness pin-type retainer at the front of the RH shock tower and detach the 2 wire harness clips from the Thermostatic Expansion Valve (TXV) manifold and tube assembly.
