What It Helps Fix

• Fluid leakage at the pump or reservoir area
• Inconsistent steering assist during turns
• Wear-related pump performance loss on older GM steering systems

Installation Notes and Tips

Before installation, verify outlet thread size, inlet connection style, and mounting-hole alignment against the original unit. Inspect the steering hoses, belt condition, and pulley fitment during service, and transfer or replace related components as needed for a complete repair. Because the reservoir is included, confirm the existing reservoir configuration matches the replacement assembly before installation.
