Whining or noisy power steering pump operation
Loss of steering assist at idle or low engine speed
Hard steering caused by pump wear or internal leakage
Fluid bypass or pressure control issues
Seal leakage from aged or damaged pump components

Installation Notes and Tips

Fits 1996-2004 Acura RL, N/A; reservoir not included; in-line filter available; use Honda/Acura power steering fluid only.
Fits 1997-1998 Acura TL, N/A; reservoir not included; in-line filter available; use Honda/Acura power steering fluid only.
Flush and bleed the system before installation, and re-bleed if foam or air bubbles are present in the reservoir.
Inspect the pulley condition before reuse; a cracked pulley or enlarged bore requires replacement.
If steering assist is inconsistent after installation, check for contamination in the flow control valve and pressure circuit.
For warranty purposes, install a filter and use the specified OE fluid.

Quality Assurance

Cardone remanufacturing reduces raw material and energy use compared with producing a new part, while still testing each unit for hydraulic efficiency and proper function. The pump is built from tested components and calibrated to support reliable operation in Acura RL and Acura TL steering systems.
