JC03SS Posted July 19, 2014 Report Share Posted July 19, 2014 I used a small pump and took mine out and put Amsoil in myself years ago. Quote Link to comment Share on other sites More sharing options...
Blown 346 Posted July 20, 2014 Report Share Posted July 20, 2014 I just normally pop the lower hose off, let it drain, pull the reservoir out, clean it out with brake cleaner,replace the reservoir, turn the wheels left and right to get it all out. put hose back, refill, turn wheel while running left to right to remove air, until its full.

D1SCSS Posted July 20, 2014 Report Share Posted July 20, 2014 The engine should be off with the front wheels off the ground when you turn the steering wheel lock to lock..... Quote Link to comment Share on other sites More sharing options...
Blown 346 Posted July 20, 2014 Report Share Posted July 20, 2014 Having the truck off the ground doesnt have to be done. the best way to force air out of the system is to force the fluid thru with the tiers on the ground and power steering fluid reservoir full. I have done many many times and never had a issue.If I did have a issue doing it this way, I would post. Quote Link to comment Share on other sites More sharing options...

D1SCSS Posted July 20, 2014 Report Share Posted July 20, 2014 GM says to NEVER have the engine running when you are bleeding the PS...Toyota has the same point of view also....You can do it any way you want, its just not the preferred method for GM.....

canadianVRss Posted July 20, 2014 Report Share Posted July 20, 2014 If the wheels are not off the ground you will airate the oil. The pump with push the air and the oil at the same time at high pressure when you turn the steering wheel, mixing the two. It will seem full, but because hydraulic oil holds air so well it will retain the air bubbles for several hours. After a good 6 or so hours it will separate again, and air will be in the system. Hydraulics 101, don't load the system when purging air. GM says to lift the wheels for a reason.... Quote Link to comment Share on other sites More sharing options...

canadianVRss Posted July 21, 2014 Report Share Posted July 21, 2014 Never had a issue with this in the last 13 years. Not trying to clash with you bud, but that's just how I was taught and practiced with most hydraulic systems. Quote Link to comment Share on other sites More sharing options...
T-Bag Posted July 22, 2014 Report Share Posted July 22, 2014 (edited) I just siphoned out what was in reservoir and replaced with RP synthetic. Repeated this process 4 more times. Siphoned every week after some light driving until it was all out. Edited July 22, 2014 by NoMoreBadAssSilvy (see edit history) Quote Link to comment Share on other sites More sharing options...

D1SCSS Posted July 31, 2014 Report Share Posted July 31, 2014 This is copied staight from my GM service information....The correct way to bleed the PS system!!!! Fill pump reservoir with fluid to minimum system level, FULL COLD level, or middle of hash mark on cap stick fluid level indicator. If equipped with hydro-boost, fully charge the hydro-boost accumulator using the following procedure: Start the engine. Firmly apply the brake pedal 10–15 times. Turn the engine OFF. Raise the vehicle until the front wheels are off the ground. Refer to Lifting and Jacking the Vehicle. Key on engine OFF, turn the steering wheel from stop to stop 12 times. Vehicles equipped with hydro-boost systems or longer length power steering hoses may require turns up to 15 to 20 stop to stops. Verify power steering fluid level per operating specification. Refer to Checking and Adding Power Steering Fluid. Start the engine. Rotate steering wheel from left to right. Check for sign of cavitation or fluid aeration (pump noise/whining). Verify the fluid level. Repeat the bleed procedure, if necessary. Quote Link to comment Share on other sites More sharing options...
