Installation Notes

Verify the vehicle year, make, model, and configuration notes before ordering. This RD5100C application list includes vehicles with rear A/C, without tube, with tube fittings, and tank-only notes, so matching the original layout is important for proper service. Confirm the existing accumulator style and line connection design on Chevrolet P20, GMC G3500, and other listed applications before installation.

Universal Air RD5100C is cataloged as an accumulator-line HVAC replacement for the listed GM applications. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
