How to Bleed Your Power Steering System

In this video, Nick from Duramax Service Center demonstrates the procedure for bleeding a power steering system. The truck being worked on required a new power steering pump due to the wear and tear caused by its large 40-inch tires. Nick explains the step-by-step process to ensure the power steering system operates efficiently.

First, the new power steering pump is installed, and the reservoir is filled to the cold mark. GM recommends starting the truck and pressing the brake pedal 10 to 15 times. After this, the truck is turned off and raised so that the front wheels are off the ground. With the engine off, the steering wheel is turned from lock to lock 10 to 15 times to expel air from the system. As air is removed, the fluid level drops. The truck is then restarted for about 5 seconds, turned off again, and the fluid level is rechecked, topping it up to the cold mark if necessary with TranSynd 668.

This process helps remove most of the air from the reservoir and significantly improves the steering performance. Nick emphasizes the use of a Dmax steering pump for its durability, especially beneficial for trucks with high mileage and large tires.
