How to Bleed Your Power Steering System

Welcome to Duramax Service Center! In today’s video, we’ll show you how to properly bleed the power steering fluid on your Duramax truck. Regular maintenance of your power steering system ensures smooth operation and extends the life of your components.

Introduction:
In this tutorial, we will guide you through the process of bleeding the power steering fluid on your Duramax. This procedure is crucial to eliminate air pockets and maintain the efficiency of your power steering system.

Step-by-Step Bleeding Process:

Step 1: Fill the Pump Reservoir with fluid to the minimum system level, full cold level, or middle of the hash mark on the cap stick fluid level indicator.

Step 2: Charge the hydro-boost accumulator. Start the engine, firmly apply the brake pedal 10-15 times, turn the engine off. DO NOT apply the brake pedal with the engine off as it may discharge the hydro-boost accumulator.

Step 3: Raise the vehicle so the front wheels are off the ground.

Step 4: With the Key on and the engine on, turn the steering wheel stop to stop 15-20 times.

Step 5: Verify the power steering fluid level.
Remove the reservoir cap, inspect the fluid level.
You want the level to be under the full cold line as overfilling is just as bad as underfilling.

Step 6: Start the engine. rotate the steering wheel from left to right. Check for signs of cavitation or fluid aeration (pump noise/whining)

Step 7: Verify the fluid level and repeat the bleed procedure if necessary.
