Tools and Materials Needed
- New power steering hose
- Socket set

Instructions:
Step 1: Prepare the vehicle.
- Park your GMC Sierra 3500 Duramax on a level surface and engage the parking brake.
- Turn off the engine and allow it to cool down completely.
Step 2: Locate the old power steering hose.
- The power steering hose is typically located on the front passenger side of the engine bay. It is a thick, black hose that runs from the power steering reservoir to the steering gear.
Step 3: Remove the old power steering hose
- Follow these steps to remove the power steering hose:
- Loosen the hose clamps at both ends of the old power steering hose using a wrench.
- Slide the hose clamps off the hose.
- Pull the old hose off the fittings at both ends.
- Allow any residual power steering fluid to drain into a catch pan.
Step 4: Install the new power steering hose
- Follow these steps to install the new power steering hose:
- Slide the new hose clamps onto the new hose.
- Attach one end of the new power steering hose to the fitting on the power steering reservoir and tighten the hose clamp.
- Attach the other end of the new hose to the fitting on the steering gear and tighten the hose clamp.
Step 5: Refill the power steering fluid reservoir
- With the new hose installed, slowly add power steering fluid to the reservoir until it reaches the "Full" mark.
- Start the engine and let it run for a few minutes to circulate the new fluid.
- Check the power steering fluid level again and add more if necessary.
Step 6: Test the power steering
- Turn the steering wheel all the way to the left and right a few times to check for any leaks or binding in the steering.
- If there are no leaks or binding, then the power steering hose has been successfully replaced.
Tips:
- When removing or installing the hose, be careful not to damage the fittings.
- You may need to use penetrating oil to loosen the hose clamps if they are rusted or stuck.
- Make sure that the new power steering hose is the correct size and length for your specific vehicle.
