Bosch Power Steering Pump P/N:KS01000594

Keep hydraulic steering assist flowing with the Bosch Power Steering Pump KS01000594. It drops in as a direct-fit replacement for the 2003-2005 Mercedes-Benz E320, 2000-2006 Mercedes-Benz S430, 2000-2006 Mercedes-Benz S500, and 2001-2006 Mercedes-Benz S55 AMG — see the Buyer's Guide tab for engine specifics. This hydraulic pump draws power steering fluid and delivers pressurized flow to the steering gear so the system can provide assist as you turn.

• Manufactured to OE specifications: designed to deliver stable hydraulic pressure and consistent steering assist across varying driving conditions.
• Direct-fit design: supplied with a pre-assembled pulley, mounting bracket, and reservoir for a faster, more straightforward installation.
• 100% functionally tested: each unit is fully tested to meet or exceed OE quality standards for leak-free, reliable operation.
• Robust internal components: high-quality materials and an optimized hydraulic design help support long-term steering performance and reduce parasitic losses.

If a worn or leaking power steering pump is behind hard steering, whining under load, or low assist, this pump replaces the original unit. Bosch backs every Hydraulic Power Steering Pump with a 1-year, unlimited-mileage warranty for non-commercial passenger cars and light trucks.
