Video: Adjusting Power Steering Pump Flow Rates With Turn One

Whether you are changing your hose connection or needing to adjust your pump’s flow rate, installing a new flow restrictor is easier than you think. Turn One Steering’s quick install video shows how to easily swap out this component.

Power Steering stopped being an option and was largely standard equipment as the muscle car era got underway in the mid-1960s. General Motors’ Saginaw power steering pumps helped usher in a simple design that became the standard for many manufacturers for decades.

Turn One Steering’s fittings and restrictors for GM-type power steering pumps.

The internal rotary-vane type pump has remained almost unchanged since its introduction. The components have remained the same for most power steering pumps. A reservoir holding power steering fluid is connected to the power steering pump. A flow restrictor fitting is installed in the pump where the pressure hose attaches to the pump. There is a return line connection at the reservoir where the power steering fluid is routed back to the pump to complete the circulation of the system.

Because these pumps have been used in many different applications, various flow restrictors are available to match various GM, and non-GM gearbox types. Turn One Steering offers several different choices of fittings and flow restrictors for GM-style power steering pumps. Turn One flow restrictors come standard with 1.3, 2.0, 2.5, and 3.0 GPM flow rate options for a wide variety of steering gear applications. Additional flow rates are available upon request.

Choosing the correct restrictor flow rate is critical to having a steering system with a normal feel. Too much flow results in overly-sensitive steering feel. Too little flow results in stiff and unresponsive steering. A properly matched flow rate between the power steering pump and steering gear improves driver feel, road feedback, and steering sensitivity for the best driving experience.
