Pump Housing: High-strength aluminum alloy housing designed for optimal durability, weight reduction, and effective heat dissipation.

Integrated Fluid Reservoir: Heavy-duty, attached plastic reservoir with an airtight cap, ensuring an immediate and stable supply of hydraulic fluid.

Rotor and Vane Assembly: Precision-engineered internal rotor and vane mechanism that generates stable hydraulic pressure for consistent steering assistance.

Pressed-On Drive Shaft: Smooth-end drive shaft assembly designed for press-fit pulley installation, transferring engine power efficiently for continuous fluid circulation.

Hydraulic Inlet and Outlet Ports: OE-style threaded high-pressure outlet and barbed low-pressure return inlet ensure leak-free integration with vehicle steering lines.

Advanced Shaft Seal System: Premium-grade, heat-resistant sealing components to effectively prevent hydraulic fluid leakage under high operating pressures.

Low-Friction Bearing Assembly: Heavy-duty internal bearings designed to support smooth shaft rotation, minimize noise, and reduce internal wear.

Disconnect the vehicle battery before starting the installation.

Always verify compatibility using the VIN number and OEM part number before installation.

Important: Since this pump comes without a pulley, use a professional power steering pulley installer/remover tool to press-fit the original pulley onto the smooth shaft; never hammer it on, as internal damage will occur.

Thoroughly flush the entire steering system with fresh fluid to remove metal debris and contaminants before installing the new pump.

Inspect all hydraulic hoses, high-pressure lines, and fittings, and replace any hardened or leaking return lines.

Use only the specific GM-approved power steering fluid required by the vehicle manufacturer; mixing incompatible fluids may destroy the internal seals.

Ensure the attached fluid reservoir is properly seated and all hydraulic connections are tightened to OE torque specifications.

Crucial: Bleed the steering system thoroughly (with front wheels off the ground, turning lock-to-lock without starting the engine first) to completely remove trapped air and prevent pump whining noise.

Start the engine, check for fluid leaks, and listen for abnormal noises or aeration signs in the reservoir.

Verify proper steering assistance during the initial road test, and recheck the hydraulic fluid level after the vehicle reaches operating temperature
