This Universal Air Ancillary Kit is organized for vehicles that use a fixed orifice tube layout, making it a practical choice when servicing the front A/C circuit on older Chevrolet and GMC trucks. The kit references the listed component numbers EX 5151C, RD 6071C, and RS 2551 for the specified applications, and AK2446 should be matched to the exact year, make, model, and A/C configuration before installation.

Common A/C Problems It Can Address

• Restoring cooling performance after aging A/C ancillary components wear out
• Replacing service parts on fixed-orifice GM A/C systems
• Addressing leaks or degraded operation in older front A/C repair jobs
• Supporting repairs on Chevrolet and GMC trucks with no rear A/C
• Helping complete a system refresh on classic Blazer and Suburban platforms

Installation Notes and Tips

Verify the vehicle uses a fixed orifice tube and does not have rear A/C before ordering or installing AK2446. Confirm the exact application against the fitment list for Chevrolet and GMC models, since coverage varies by year and platform. For best results, inspect the surrounding A/C components and replace any worn or contaminated parts during service.

Quality Assurance

Universal Air AK2446 is cataloged as an Ancillary Kit for defined GM applications, with fitment tied to specific model years and A/C configurations. Part number AK2446 should be used as the primary reference when matching the kit to the vehicle.
