Product Details

The Four Seasons 83208 accumulator is built for HVAC systems that use an accumulator-style layout on the low-pressure side of the A/C circuit. It helps manage refrigerant flow and moisture separation in the system while matching the listed fitment for 1999-2007 Chevrolet Silverado and Sierra trucks, 2000-2006 Tahoe, Suburban, Yukon, and Escalade applications, plus 2002 Hummer H1 and 2003-2007 Hummer H2 coverage. This part number 83208 is also cross-referenced to Continental 49123 for the same application.

Compatible With: 1999-2005 Chevrolet Silverado 1500, 2001-2005 Chevrolet Silverado 2500 HD, 2000-2005 GMC Yukon XL 1500, and other listed GM truck and SUV applications with the specified P-nut fitting and switch-port configuration. For 2006 Cadillac Escalade, Escalade ESV, and Escalade EXT, the notes specify P-nut fitting clocked at 12:00 and no rear A/C. For 2006 Chevrolet Silverado, Sierra, Avalanche, Tahoe, Suburban, Yukon, and related models, verify the clocking and rear A/C notes before ordering.

What It Helps Address

• Loss of A/C cooling performance caused by a saturated or restricted accumulator
• Moisture buildup in the refrigerant circuit
• Improper refrigerant storage on the low-pressure side of the system
• Leak concerns at aging accumulator seals and fittings
• HVAC service replacement needs on GM and Hummer platforms

Installation Notes and Tips

Confirm the vehicle’s A/C layout, fitting style, and clocking before installation. This accumulator uses P-nut fittings and a switch port, and the listed applications include models with and without rear A/C depending on year and trim. Replace the sealing components during service, inspect the surrounding lines for wear or contamination, and evacuate and recharge the system according to factory specifications after installation.

Quality Assurance
