Product Description
The CARDONE 21-5242 Remanufactured Power Steering Pump is engineered to meet or exceed original equipment performance. Each pump undergoes rigorous examination to identify potential OE weaknesses, and where applicable, upgraded components are implemented to improve durability and service life.
All major internal components—including campacs and spool valves—are triple-tested to ensure consistent hydraulic output. The pump is assembled with 100% new O-rings and high-grade HNBR seals that resist heat-related breakdown far better than conventional materials. Precision-surfaced shafts minimize early seal wear, while all units come equipped with fully tested and calibrated pressure relief valves.
Every pump is computer-tested for hydraulic efficiency, including pressure, bypass function, fluid flow, valve operation, steering effort, and noise performance. CARDONE’s eco-friendly remanufacturing methods reduce energy and raw material usage by up to 80%, providing a high-quality, sustainable replacement solution.

Installation & Warranty Notes
-
Flush the power steering system completely before installing the new pump to remove contaminants.
-
Always use OE-recommended power steering fluid to prevent noise, wear, or premature pump failure.
-
Install an in-line steering fluid filter for maximum system protection and warranty compliance.
-
Verify hose condition and check for system leaks before installation.
-
Ensure belt alignment and tension are properly adjusted once installed.
