- 2007 Silverado 2500 HD classic power steering air bleed hydro boost. Front wheels off the ground, fluid level on full cold and cap secured. Place rags around the power steering reservoir and underneath truck to catch possible spillage. Ignition on, engine not running, turn steering wheel all the way left and all the way right that counts as one. Do this five times and on the fifth steering stop push on brake pedal three times. This counts as one cycle. It can take up to 50-90 cycles to clear the air out of system. Check fluid level frequently and fill if needed and secure reservoir cap. Side note with the wheels lifted at the front you can get a false fluid level indication with the incline. Check fluid level when u have finished and the front wheels are back on the ground before turning vehicle on for results.
Thanks for the video!
I have a 2003, otherwise the same truck, and having huge issues with this. Had to replace the metal hose to the left of the system (inlet/pressure hose?) and calipers at the same time- struggling to get full power back to my brakes and I bet my power steering is not as good as it could be either, so not back on the road yet.
I haven't tried this exact cycle but will!
So is anything different when its a new system install. Im installing a new steering box, power steering pump and hydro boost in my 65 cutlass
I rebuilt one Hydro boost. It blew out in one week then I replaced it with a Duralast from AutoZone and it blew out immediately what would be causing my seal to blow out in my Hydro boost
The pressure line running from the power steering to the hydro boost needs to be bled at the fitting. So the fitting that screws into the hydro boost at the top near your brake fluid reservoir. Ill look to see if I find the write up or video.

@@2007Silvy I'm assuming I keep blowing the O-ring because both times I did not prime the system with the engine off I jacked it up and turn the wheels with the engine on first
@@2007Silvy watched a lot of videos. I have not seen nobody bleed it through cracking the line. They just turned the wheel back-and-forth and pump the brakes with the engine off.
Yeah never mind the cracking line. Do the process with the engine off 😅
Did a flush, have a grinding sound at certain steering spots, is there air in my system?
Grinding or whining sound? A whining sound would indicate that you do have air in the system.
@@2007Silvy figured it out. Steering shaft rubbing on headers, have to readjust
@@Neutsie I love it when the problem is figured 👍🏽
Would air in system effect stopping power with brakes ??
Yes. I think you would feel the brake pedal vibrate or pulsate too
Also I did this procedure with the Power steering cap on. Do it with the cap off. Aslong as the wheels are completely off the ground you should have no spillage
@2007Silvy thank you sir for the advice I appreciate the video🇺🇲💯
You do this with the cap on?
Im only curious as to where the air escapes
I have tried it with the cap off and the fluid level will rise past the reservoir and spill over. Needs to be done with the cap on!
You can hear the air hissing out of the cap and also you will see small bubbles in the fluid level. Which will continue to show for numerous cycles.
@2007Silvy cool, thanks for the reply. Appreciate it! I had a hose come off somehow, and I put it back on, but now the power steering is whining. I'm hoping this is all I have to do, at least til winter is over.
@@2007Silvy I did same base on other videos saying the cap should be off, what a mess. With the cap on it will still bleed air and a little fluid, but not like when the cap is off, it flows like a volcano.
