It is a Sanden‑style QP7 series unit that pumps R‑134a refrigerant through the HVAC system to provide cab cooling. The compressor features a direct‑mount design and a 119 mm Poly‑V eight‑groove clutch that engages when the A/C is turned on. You typically replace it when the old compressor seizes, leaks, or fails to build pressure, causing the air conditioning to stop blowing cold air.
