Product Details

CARDONE Power Steering Pump 20-1003 is a remanufactured hydraulic pump for Cadillac CTS models from 2008 through 2014. The aluminum housing, O-ring hose port, threaded outlet, and press-on pulley attachment are matched to the original application. This unit is supplied with a hydraulic pump, instruction sheet, and sealing kit, and it uses a remote reservoir setup with no reservoir included. For the Cadillac CTS, reservoir not included, an in-line filter, OE fluid, and a full system flush are required for warranty service.

This part cross-references Cadillac 25914590 for the same application.

Common Steering Problems It Can Address

• Hard steering at low engine speed
• Whining or noisy pump operation
• Loss of hydraulic assist after pump wear or contamination
• Fluid leaks from worn seals or O-rings
• Inconsistent steering effort caused by internal valve or flow issues

Installation Notes and Tips

Before installation, inspect the pulley fit on the replacement shaft, since a damaged or mushroomed pulley bore can prevent proper seating. Flush the steering system, bleed air from the circuit, and verify that the steering gear and related components are not binding. If assist returns only at higher engine rpm, contamination in the flow control valve circuit is a common cause and the system should be cleaned and filtered before re-test.

Quality Assurance

Each unit is hydraulically efficiency-tested and computer-checked to confirm pressure, flow, valve function, steering effort, and noise. CARDONE remanufacturing also reduces raw material and energy use compared with producing a new part, while preserving OE fit and function for Cadillac CTS service.
