Bosch Power Steering Pump P/N:KS01000701

Keep hydraulic steering assist firm and responsive with the Bosch Power Steering Pump KS01000701. It drops in as a direct-fit replacement for the 2011-2012 Mercedes-Benz C300, 2011 Mercedes-Benz C350, 2010-2011 Mercedes-Benz E350, and 2010-2011 Mercedes-Benz E550 — see the Buyer's Guide tab for the engine-level applications. This hydraulic pump draws fluid from the reservoir and delivers pressurized flow to the steering gear so the system can provide the assist that lightens steering effort.

• OE-engineered performance: manufactured to original equipment specifications for consistent steering assist across 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 tested to meet or exceed OE quality standards for leak-free, reliable operation.
• Efficient hydraulics: an optimized design helps reduce parasitic losses while maintaining the required assist output.

Robust internal components are built to support long-term reliability, and Bosch backs the pump with a 1-year, unlimited-mileage warranty for non-commercial passenger cars and light trucks. If a worn or leaking pump is the cause of heavy steering, whine, or lost assist, this replaces it.
