Hello Guys/Gals of the org today I bring you a Tech Guide for the 3rd gens with a 2.4l engine(may apply to other years and engines not sure only did this on a 2000 cavalier with a 2.4l twin cam). This post is solely intended as a reference for the power steering pump replacement process. Proceed at your own risk I will not nor will the org be responsible for any loss or damages occurred as a result of your attempt at this. If you are not comfortable with this pay a pro. Also the steps may be needed to be adapted to your application as I have a WAI installed on my engine(concepts the same tho)
Ok so with that said lets begin. First off what you will need to do this repair.
1.Replacement Power steering pump
2.Standard pliers
3.13mm box wrench
4.5/8s box wrench
5. flat head screw driver(in my case)
6.container to catch fluid
7.set of hands(lol obviously)
The culprit a spun PS pump.
The Overall Before Start(yes its dirty but thats not the issue at hand)
The Tear Down.......
Remove the ox2 sensor just unclasps.
Using Flat head loosen clamp holding intake tube to throttle body and (if stock intake you will also need to remove the 4 phillips head screws for the upper right side)
Loosen this bolt (don't remove yet) to remove intake.
Using pliers squeeze the clamp and slide down tube place catch container under pump and slide hose off(caution fluid will instantly flow out when removed)
Using the 5/8s box wrench loosen and remove hard line from under pump rest.
Using a 13mm box wrench remove these two bolts that hold the pump in place. Then remove pump you will see the following
The pump removered from the engine block.
The new replacement pump
Now installing the new pump you need to align these two noted parts together very simple they are hexed.
Bolt the pump in place using the previously removed 13mm bolts leaving the top slightly loose for the intake to bolt back to.
Reinstall the hard line to the bottom of the pump and bolt down using 5/8 wrench.
Reinstall the hose as show by my fingers
Repostion clamp on hose to secure the line to the resovr.
Place the intake tube back in place and
Tighten clamp
Bolt 13mm
Push and clip
Fill resovr with GM approved POWER STEERING FLUID(i used advanced auto parts brand) following dip stick mounted under cap to the recommended specs.
Start engine let cycle turn wheel left- right top off fluid as needed. Mine took apx 16oz of fluid.
Place cap on resvr notice the new pump.
All Done You have just successfully replaced the power steering pump. enjoy the comfort of ps again lol.
This project will take from 15-30 minutes and cost depending parts chosen and what not cost me 78.00 for the replacement pump/resrvr from advanced auto, 2.94 for a qt of ps fluid.Hope this will help out those who need to do this in the future.

P.S. Lets make it a sticky.
i call sticky !! can i get a second motion ?
I will second the sticky motion.
Great information and full of pics. Thanks.
let me add, it helps in the bleeding process to have the front wheels off the ground, Disable fuel and crank the car instead of starting it that way the fluid wont aerate..

also to add found this pic the neon green indicated the four phillips head screws and the single flat head clamp needed to remove the stock intake to do this repair.

Might want to fix it before you "make it a sticky"
That part is an AIT sensor (Air Intake Temperature), NOT an o2 sensor.
Decent write up other than that.
