Detailed Description

This Four Seasons accumulator is designed for HVAC systems that require a direct-fit replacement with the correct inlet, outlet, and switch-port configuration. The 33198 accumulator uses a female O-ring inlet, male insert O-ring outlet, and aluminum housing to match common OE-style layouts on GM platforms. It is a practical choice for restoring A/C performance on vehicles such as the Chevrolet S10, Chevrolet S10 Blazer, GMC Jimmy, and Pontiac Firebird, where accurate fitment and refrigerant management matter.

Four Seasons 33198 also cross-references UAC RD8813C for the same application.

What It Helps Address

Loss of A/C cooling performance from a worn accumulator
Moisture buildup in the refrigerant circuit
Incorrect fitment after A/C system service
Leaking O-ring connections at the accumulator ports
Switch-port replacement needs on supported HVAC layouts

Installation Notes and Tips

Verify inlet and outlet orientation, switch-port location, and body dimensions before installation. Replace the specified green O-rings during service and confirm the system uses the correct accumulator style for the vehicle. This unit is listed without a service port and without mounting hardware. The printed foot note indicates the swivel-top/universal accumulator option is also available as Part No. 33705 and does not require a tube kit.
