Detailed Description

The 3411966 expansion valve is a service replacement for vehicles that use a refrigerant metering device at the evaporator inlet. It meters refrigerant flow so the evaporator can absorb heat effectively, which is essential for stable cabin cooling performance. This part cross-references UAC EX10501C for the same application.
