Detailed Description

Four Seasons 83047 is an aluminum A/C accumulator for the Cadillac Seville, covering 1998-2004 Cadillac Seville accumulator replacement needs. In an automotive air conditioning system, the accumulator helps manage refrigerant flow and moisture control on the low-pressure side, making it an important service part when restoring cooling performance. This unit uses P-nut fittings, has no service port, and does not include a switch port, which helps match the original system layout on the listed vehicle application. This part cross-references Monroe Shocks & Struts 210279 for the same application.

What It Is Used For

• Replacing a leaking or corroded A/C accumulator
• Restoring proper refrigerant system operation on a 1998-2004 Cadillac Seville
• Addressing moisture contamination in the HVAC refrigerant circuit
• Correcting fitment issues caused by damaged P-nut fittings
• Servicing an accumulator that no longer matches OE-style dimensions

Installation Notes and Tips

Verify the vehicle’s existing accumulator uses P-nut inlet and outlet fittings, no service port, and no switch port before installation. Replace the specified O-rings with the correct [24404] slimline washer style during service, and inspect the surrounding A/C lines and seals for wear or contamination. Proper evacuation and recharge procedures are required after HVAC component replacement.
