Product Description
The CARDONE 20-7920 remanufactured power steering pump restores smooth, consistent steering assist on select Chevrolet & GMC C/K/R/V series trucks/SUVs and P-chassis applications. Each unit is engineered to meet or exceed OE performance and durability, using premium HNBR seals and 100% new O-rings to resist high heat and fluid breakdown. Critical internals (cam packs, spool valves, shafts) are triple-tested, and every assembly is computer-tested for pressure, bypass, flow, steering effort, and noise—ensuring reliable, long-lasting performance. CARDONE’s process also cuts raw material and energy use by up to 80% vs. new production.

Install an in-line return-side filter to capture debris and protect the new pump.
-
Verify pulley press depth and belt alignment prior to startup.
-
Inspect hoses/fittings/seals and bleed the system thoroughly to prevent aeration.
