Power Steering Pump 20902363
The 20902363 Power Steering Pump, also known as 20902363 20976855 Power Steering Pump, 20976855 for CHEVROLET CAPTIVA SPORT, 20976855 for CHEVROLET EQUINOX and 20976855 for CHEVROLET TRAVERSE, is an OE-specification hydraulic vane pump designed for General Motors (GM) hydraulic power steering systems. Driven by the engine through a serpentine belt, the pump continuously delivers pressurized hydraulic fluid to the steering gear, providing smooth steering assistance, precise steering response, and reduced steering effort under all driving conditions.
Manufactured to GM OE specifications, the pump features a precision-machined vane rotor, integrated pressure-relief and flow-control valve, durable aluminum housing, and premium sealing components. It delivers stable hydraulic pressure, low operating noise, and excellent durability, making it an ideal direct replacement for the original equipment unit. OEM 20902363 supersedes 25803117 and 25964298.

Note: OEM 20902363 was originally fitted to 2008–2009 Chevrolet Equinox and 2008–2009 Pontiac Torrent, and is widely cross-referenced by aftermarket manufacturers for additional GM Lambda-platform vehicles. Always verify compatibility using the VIN number and OEM part number before installation.
Installation and Usage Notes
Disconnect the vehicle battery before installation.
Inspect the steering rack, hydraulic hoses, reservoir, and fittings for contamination or wear.
Flush the hydraulic steering system if the previous pump has failed internally.
Fill the system only with the power steering fluid specified by the vehicle manufacturer.
Tighten all hydraulic connections according to OE torque specifications.
Bleed the steering system thoroughly after installation to remove trapped air.
Check for hydraulic leaks and abnormal operating noise.
Verify proper steering assistance during the initial road test.
Recheck the hydraulic fluid level after the first test drive.
