Help keep moisture and debris out of your air conditioning with the DENSO A/C Receiver Drier, part number 478-2040, a direct-fit replacement for the 2001-2010 Volkswagen Beetle and 2002-2005 Volkswagen Jetta, all engines. The listed applications use one drier.
The receiver-drier is often overlooked in regular vehicle service, but it plays an important role in A/C operation. It manages the flow of liquid and vapor refrigerant through the system and is designed for smooth, surge-free operation. Its desiccant package isolates harmful moisture from the system. That moisture can corrode internal components from the inside out and lead to costly leaks.
When major A/C service is performed, leading service authorities often recommend replacing the receiver-drier. This unit is part of DENSO's First Time Fit® line, which is built to demanding factory standards. Signs that it may need replacing include weak cooling or moisture found in the system during service. Diagnose the A/C system before replacing parts. Country of origin: China.
