Installation Notes and Tips
Reservoir is not included. For warranty-related installation requirements, use OE fluid, flush the system, and install an in-line filter. If the original pulley is being transferred, verify shaft and pulley fit before installation. After installation, bleed the system fully to remove trapped air; foam or bubbles in the reservoir indicate the system still contains air. If steering assist is uneven after replacement, inspect the steering gear and related components for binding or contamination.
Quality Assurance
Every Cardone 21-5426 pump undergoes hydraulic efficiency testing and final computer testing to verify pressure, flow, bypass function, valve operation, steering effort, and noise. The remanufacturing process also reduces raw material and energy use compared with producing a new part.
