ACDelco 36P1557 Power Steering Pump

Description:

Features and Benefits:

• All components are closely inspected and validated to meet the strictest quality standards to improve part durability
• Assembled units are 100% functionally tested for leak-free performance, prior to packaging, to help guarantee unit performance that meets vehicle specifications
• Cam packs closely are inspected for any wear or imperfections and replaced with new when needed
• High-temperature seals are utilized for durability and reliability
• Housing is cleaned and inspected at multiple stages in the manufacturing process to minimize corrosion and rust prior to component assembly
• Input shaft seal surfaces are micro-finished for precise fit and leak-free performance
• Multiple cleaning and washing stations, with regular contamination audits, for every component inside the pump minimize internal contamination and increase part service life
• Sealing surfaces are polished, restored, and checked for microfinish. This helps ensure maximum sealing to minimize leaks.
• Seals and O-rings are replaced with new parts for extended life and reliability

Features and Benefits:

• – After any service of the power steering system, always bleed the air from the system and verify proper system operation. An accurate fluid level cannot be obtained unless air is bled from the steering system. The air in the fluid may cause pump cavitation noise as well as pump damage over a period of time.
• – Always check the specific manufacturer's service information for the correct power steering fluid to use.
• – Always follow the manufacturer's specific instructions on flushing, but remember the following: always flush out the power steering fluid in the lines before removing the old pump and be ready with two or more quarts of power steering fluid for the flushing process.
• – Check power steering fluid levels periodically and add fluid when necessary.
• – Flushing the system will help eliminate any residual contaminants from causing future pump failure. Dirty or contaminated fluid may cause low or no pressure from the power steering pump, causing the relief valve to stop functioning.
• – Have your vehicle inspected if it exhibits any of the following symptoms: unusual noise when turning the steering wheel, a shimmy or shake in the steering wheel, heavy or unresponsive steering at low speeds or during parking lot maneuvers, and/or the steering wheel does not properly return to center.
• – If you live in areas that experience harsh, winter weather, have the entire steering system inspected before winter arrives to help ensure safer driving.
• – It is a good idea to replace O-rings when doing any steering system service. Reusing old O-rings can cause leaks.
• – Keep in mind that fluid color is not an indication of fluid condition.
• – The most significant root causes of power steering failures that could lead to pump replacement are system contamination, improper pulley installation, and using the wrong fluid. Following the recommended service procedures during power steering pump replacement address these root causes and help ensure the longevity of the new power steering pump while reducing the chances of premature pump failure.
