Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Receiver Drier (Integrated With The Condenser)
The receiver drier is integrated with the condenser. It is located on the high-pressure side, between the condenser and the expansion valve, on the refrigerant circuit.
The receiver drier consist of a replaceable filter cartridge. It has the task of taking up and binding moisture (water) found in the system as well as filtering foreign substances.
The refrigerant in a liquid state passes at high pressure from the condenser into the receiver drier. The refrigerant then flows on to the expansion valve.
If the cooling system has been opened (unplugged) for 10 minutes or leaked for a period, so that moisture has been able to enter the system, the receiver drier must be replaced. When replacing the receiver drier, the new receiver drier contains leakage indication color that spreads through the system as soon as the system is started.
The receiver drier can only absorb a limited amount of moisture. If the system contains more moisture than the receiver drier can handle it may lead to icing which blocks the expansion valve.
