Hey gang; I've read all the posts related to PS issues, and I've narrowed it down to my pump needing replacing. 4.6 V8 AWD
Never replaced a pump before.
I've got one on order from Rock Auto. What tools are needed besides basic hand tools to do this job? Also, am I correct that I only need to move the steering side to side several times to bleed the system once the job is done?
You might need the power steering pulley removal tool part #27031 for rent at AutoZone for $30. Have both front wheels.off the ground slowly go lock to lock to bleed the air out. You are on the right track. I believe the bolts are 13 or 15mm and the pressure line should be a 16mm wrench if I remember correctly. That's the 3.6 engine though but should be similar although not 100% never actually had the new 4.6 in front of me it's always the 3.6 I'm working on.
Watch out for the Autozone puller. I just replaced a 4.6 ps pump and that tool tore the pulley apart. Had to get a new one.
Remove the PS reservoir and put it aside.
Use a ratchet pry bar to release tension on the belt, and remove it
Carefully remove the pulley so that you can get at the bolts that hold the pump to the block. GM has a special tool to get his pulley off
The high pressure line to the steering rack at the bottom of the pump uses a one time only snap connection. Your new pump should come with a new one to replace your old one. Careful when you take the pump out. Disconnecting the high pressure line is tricky. You may need a new line to insure a tight fit.
The bracket attached to the pump comes off last and gets reused on the new pump.
Important: DO NOT try to remove the power steering pump nut from the power steering pressure hose. The power steering pump nut is a quick-connect fitting and once the power steering pressure hose is installed, the quick-connect fitting cannot be removed. If a new power steering pressure hose is required for further repairs, then a new power steering pump nut will be required.
