130-0263-450-6568 A C Expansion Valve — Cat 3046 3054

This is an A/C Expansion Valve, a vital component within the vehicle's air conditioning system responsible for regulating the flow of refrigerant into the evaporator. It is engineered to meet strict OEM performance criteria, ensuring precise temperature control and efficient cooling, unlike a clogged or malfunctioning valve that leads to inconsistent cabin temperatures. Operators might experience poor or no cooling, intermittent AC performance, or excessive frost buildup on AC lines when this valve is faulty.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first sign of a failing expansion valve is often inconsistent or reduced cooling performance from the air conditioning system. If left unaddressed, the system may cease to cool altogether, potentially leading to compressor damage due to improper refrigerant flow or pressure. Continued operation with a faulty valve can compromise the entire AC system's integrity.

Installation Tip

Ensure the AC system is properly evacuated of refrigerant before removing the old valve to prevent environmental release and safety hazards. Always install new O-rings and ensure they are properly lubricated before seating the valve.

Service Note

The receiver-drier or accumulator should always be replaced when servicing the expansion valve to ensure system purity.
