Autopart International 2403-313388 A/C Expansion Valve

The Autopart International 2403-313388 A/C Expansion Valve is a direct replacement component designed to regulate refrigerant flow in automotive air conditioning systems. This expansion valve meters the precise amount of refrigerant entering the evaporator, ensuring optimal cooling performance and system efficiency.

Key Features:

• Precision-engineered valve mechanism for accurate refrigerant metering
• Maintains proper pressure differential between high and low side of A/C system
• Constructed with durable materials to withstand temperature extremes and refrigerant exposure
• Direct-fit design for simplified installation
• Helps maintain consistent cabin temperature control

The expansion valve plays a critical role in A/C system operation by converting high-pressure liquid refrigerant into a low-pressure mist before it enters the evaporator core. This component is essential for proper cooling system function and should be replaced when symptoms such as insufficient cooling, frosted evaporator, or inconsistent A/C performance occur.
