Keep moisture and debris out of your A/C system with the Four Seasons A/C Accumulator with Hose Assembly / A/C Refrigerant Suction Hose (MPN 83046). It drops in as a direct-fit replacement for the listed applications: the 2002 Chevrolet Trailblazer, 2002 Chevrolet Trailblazer EXT, 2002 GMC Envoy, and 2002 GMC Envoy XL — see the "Vehicles it fits" section for engine details.
- Accumulator / filter drier: Acts as a filter, removing moisture and contaminants from the air conditioning system — contaminants that flushing alone cannot remove, which is why replacing the accumulator / filter drier is essential during service.
- Desiccant absorption: Moisture is absorbed through a desiccant bag. A leaking or "open" system can saturate the bag within a few hours, making the unit ineffective.
- Leak-free build: Quality welds for a durable design, plus high-quality desiccant for appropriate absorption.
- Installation hardware: Necessary gaskets, o-rings and seal are included for easy installation.
Replacing the accumulator / filter drier is required to validate compressor warranty and should be done anytime the system is serviced. Backed by over 50 years of Four Seasons mobile A/C experience.

Frequently Asked Questions
What does this accumulator do?
It acts as a filter drier, removing moisture and contaminants from the A/C system that flushing cannot remove, while its desiccant bag absorbs moisture that circulates with the refrigerant.
Which vehicles does MPN 83046 fit?
It's a direct-fit replacement for the 2002 Chevrolet Trailblazer, 2002 Chevrolet Trailblazer EXT, 2002 GMC Envoy, and 2002 GMC Envoy XL. Check the "Vehicles it fits" section to confirm your vehicle.
Are gaskets and seals included?
Yes. The necessary gaskets, o-rings and seal are included for easy installation.
Do I need to replace the accumulator when servicing the A/C?
Yes. Replacement is required to validate compressor warranty and should be done anytime the system is serviced, since a saturated desiccant bag makes the unit ineffective.
Why can't I just flush the system instead?
Some contaminants cannot be removed by flushing, so replacing the accumulator / filter drier is essential to remove trapped moisture and debris.
