Description

Keep moisture and contaminants out of your A/C system with the Four Seasons A/C Accumulator 33133, a direct-fit replacement for the 1989-1990 Chevrolet C1500, C2500, C35, C3500, K1500, K2500 and K3500 and the 1989-1990 GMC C1500, C2500, C3500, K1500, K2500 and K3500 (see the Buyer's Guide tab for the full engine-level list). Backed by more than 50 years of mobile A/C experience, it's built to help your refrigerant system run clean and dry.

Filters and dries: The accumulator/filter drier acts as a filter, removing moisture and contaminants that can't be flushed from the system — which is why replacing it during service is essential.
Desiccant absorption: Moisture is absorbed through a desiccant bag; a leaking or "open" system can saturate that bag within hours, so a fresh unit is important.
Durable build: Quality welds are used for a leak-free design, with high-quality desiccant for appropriate absorption.
Install-ready: Necessary gaskets, O-rings and seal are included for easy installation.

Four Seasons notes that replacing the accumulator/filter drier is required to validate compressor warranty and must be done anytime the system is serviced.

Frequently Asked Questions

What does this accumulator do?

It acts as a filter that removes moisture and contaminants from the A/C system using a desiccant bag, helping protect the refrigerant circuit and other components.

Does it come with installation hardware?

Yes. Four Seasons includes the necessary gaskets, O-rings and seal for easy installation.

Which vehicles does the 33133 fit?

It's a direct-fit replacement for 1989-1990 Chevrolet and GMC C1500, C2500, C3500 (plus Chevrolet C35) and K1500, K2500, K3500. See the Buyer's Guide tab for the full list.

Why should I replace the accumulator when servicing the A/C?

Its desiccant can saturate within hours if the system is opened or leaking, and Four Seasons states replacement is required to validate compressor warranty whenever the system is serviced.

Can contaminants just be flushed out instead?

No. Four Seasons notes these contaminants cannot be removed by flushing, so replacing the accumulator/filter drier is essential.
