Power Steering Pump with Reservoir (Single Return Port) FIT 1999-2014 Chevy Silverado Tahoe Suburban GMC Sierra Yukon, 12V DC Accessory Drive Replaces 20-8740 15909824 (Non-Hydroboost) - 1 Pack

Vehicle Compatibility Matrix (1500 Series & SUV): FIT 1999-2014 Chevy Silverado / GMC Sierra 1500 FIT 2000-2014 Chevy Tahoe / Suburban / GMC Yukon 1500 FIT 2002-2014 Cadillac Escalade / 2003-2009 Hummer H2 (Note: Fits models with SINGLE return port on reservoir only) Physical Technical Parameters: - Component State: 100% Brand New (Non-Remanufactured) - Reservoir Type: Integrated Plastic with Cap - Port Configuration: Single Return Port / Threaded Pressure Outlet - Hardware: High-Pressure Aluminum Body & Steel Rotors - OE Reference: 20-8740, 15909824, 26041538, 208740 Mechanical Stability & Testing: Every Power Steering Pump undergoes 100% factory flow stability testing. The hardware is treated for environmental exposure to ensure long-term salt spray endurance and maintain proper fluid system geometry without excessive mechanical play in the internal bypass valve assembly. Professional Installation Standards: To maintain proper steering geometry, never reuse old O-rings on the pressure line. Manual pressing of the pulley using a professional installer tool is mandatory; do not use a hydraulic press. Professional technician installation is required to verify hydraulic continuity and secure electrical grounding.

• Precise Fitment Protocol: FIT 1999-2014 Chevy Silverado / GMC Sierra 1500, FIT 2000-2014 Tahoe Suburban Yukon, FIT 2002-2014 Cadillac Escalade, FIT 2003-2009 Hummer H2. Position: Engine Accessory Drive. Non-Compatibility Notice: Engineered for models with Vacuum Brake Boosters; does NOT fit models with Hydro-boost systems (Verify your original unit has only one return port).
• Integrated Reservoir Hardware: Features a 100% brand new (non-remanufactured) pump assembly with an integrated plastic reservoir, a high-pressure hose barb inlet, and a precision-threaded pressure outlet. The pump body is constructed from high-pressure aluminum casting to ensure dimensional stability and exact physical interface with factory mounting brackets.
• Internal Hydraulic Engineering: Constructed with internal steel rotors and high-pressure seals engineered to provide a constant hydraulic flow rate. Every unit undergoes 100% factory pressure and flow stability testing to verify physical output integrity and maintain factory-spec hydraulic assistance across all specified engine RPM ranges.
• Symptom-to-Spec Restoration: Engineered to address excessive mechanical resistance and resolve internal hydraulic instability. This unit restores factory handling characteristics of the steering system, maintaining proper fluid geometry and preventing physical displacement during high-torque turning maneuvers or low-speed operation.
• Technical Installation Limits: Professional installation is required. The pulley is NOT included; a specialized power steering pulley installer tool must be used to prevent physical damage to the internal pump shaft. The system must be flushed with factory-approved fluid before integration to maintain seal integrity. Includes 100% inspection for rotational torque.
