Rear Cooling Expansion Valve ?❄️

Why This Valve Is Essential

This valve plays a critical role in your vehicle's rear air conditioning system. It regulates the flow of refrigerant into the evaporator, ensuring optimal cooling performance for passengers in the back. A properly functioning unit maintains cabin comfort, especially in hot climates or long trips.

How It Works

The valve senses the temperature and pressure of the refrigerant, opening or closing to control the refrigerant amount entering the evaporator. This process allows the system to absorb more heat, providing consistent cool air. The precise control helps prevent the evaporator from freezing and ensures efficient cooling.

Risks of a Broken Valve

• Reduced or no rear cooling
• Poor passenger comfort
• Evaporator freeze-up or overheating
• Increased system wear
