Thermostatic Expansion Valve Manifold and Tube Assembly

THERMOSTATIC EXPANSION VALVE MANIFOLD AND TUBE ASSEMBLY







Removal and Installation

CAUTION: Refrigerant compressor oil (mineral oil) should be used to lubricate R-134a refrigerant system O-ring seals only and should not be added to the R-134a refrigerant system as an A/C compressor lubricant. PAG refrigerant compressor oil only should be used as an A/C compressor lubricant.

NOTE:
- Installation of a new receiver/drier is not required when repairing the air conditioning system except when there is physical evidence of contamination from a failed A/C compressor or damage to the receiver/drier.
- Lubricate the coolant hoses with plain water only if needed.
