Power Steering Pump with Reservoir 20-8740 - Direct Fit Replacement

Our review of the Power Steering Pump with Reservoir 20-8740 finds it best suited for owners who need a direct-fit replacement for late model GM full-size trucks and SUVs. The single biggest reason to buy is its targeted compatibility and OE reference coverage, which makes it a straightforward swap for vehicles that list those part numbers; the reviewer found the pump straightforward to install and useful for restoring steering function quickly. This review focuses on real-world fit, noise and durability based on user feedback and the product's stated fitment.

Key Features

• OE Reference Coverage: Replaces multiple OE reference part numbers so buyers can match their required number before ordering for a correct fit.
• Wide Vehicle Fitment: Fits many 1999-2014 Sierra, Silverado, Escalade, Tahoe, Yukon and related models, reducing the need to search multiple aftermarket options.
• Integrated Reservoir: Includes the reservoir for a complete pump assembly, which simplifies installation and fluid management on replacement.
• Noise Reduction Aim: The pump is designed to ensure smooth operation and help quiet whining in many installations, according to the product description.
• High Quality Materials: Built from materials intended to meet the demands of full-size truck and SUV steering systems for standard replacement use.

Who It's For

This pump is for DIY mechanics and repair shops servicing 2007-2014 Escalade, Tahoe, Yukon and compatible Sierra and Silverado models that list the listed OE reference numbers. It is also for owners who prefer to verify an OE number and install a complete pump and reservoir assembly to restore steering assist quickly.

It is not the best option for drivers who need a lifetime performance upgrade or a completely silent, premium aftermarket unit; some customers reported mixed performance and intermittent noise or squeal which suggests those seeking maximum long-term durability or guaranteed quiet operation should consider higher-end or OEM parts and warranty-backed options.
