Replacing the Power Steering Pump
I did a search and didn't find too much info on how to replace it. I consider myself to be a decent "Handy Homeower type of Mechanic".
...so, how easy/difficult is it to replace the power steering pump? I have a 91 Z28 with the 5.7TPI. I have Haynes Manual but It has been misplaced, so that does me no good.
Any help/pointers/advice would be greatly appreciated.
Thanks in Advance.

Re: Replacing the Power Steering Pump
Its not hard at all. I took mine off to paint it. You just a pulley puller and a few wrenches.

Re: Replacing the Power Steering Pump
You can 'rent' the pulley remover from AZ or one of the others for 'free'. Don't try to use a regular claw type puller on it. You could probably even take the old one in and swap them at the counter.
I'd go ahead and install an in-line power steering filter on the system to clean any crap from the old pump out. For a few dollars you can get one that slides inside the return line. Cheap insurance.

Re: Replacing the Power Steering Pump
Follow up question...approx how many quarts of PS Fluid will I need to refill everything?
If I read it correctly, I don't need to take the pulley off to remove pump from the engine...is that correct? Because a friend of mine offered to remove/swap the pulley, I just need to bring it to him. I plan on removing the pump this weekend.

Harbor Feight-$12.99
Works like a charm, directions included. Ive used mine probably 30 times over the years so it is durable

Re: Replacing the Power Steering Pump
That's the right filter.
You won't have to remove the pulley to remove the pump, but you will have to remove the pulley to install the new pump onto the pump mount (and the new pump won't have a pulley). You'll see. It's very simple. Just be careful not to put pressure on the new pump reservoir when tightening the belt.
One quart will likely be more than enough.

...and if you want to go the trick route
I run about 3 qt fluid into a hydroboost, and cooler, and then a remote reservoir with dual return lines and a massive internal filter. I can pull the cap and still put my finger into the fluid even after an haur of nornal cruising down a freeway- its stays that cool.

Re: Replacing the Power Steering Pump
I know this post is a bit old but it keeps with the theme of a follow up question.
In regards to the inline p/s fluid filter, MUST it go on the pump inlet hose, or can it go on the outlet hose as long as it's flowing in the proper direction, away from pump?
Directions are pretty clear about it going to the pump but there's no way I'm getting it to work with the stock set up with that tight azz loopdy loop. Only the return offers enough straightaway hose possibility to allow the space needed to make it work.
Any ideas???

Re: Replacing the Power Steering Pump
I replaced the pump on my 1991 z28. Here's what I did
Disconnect battery
Disconnect (2) terminals behind alternator
Alternator is mounted to bracket with 3 bolts (1) being a long torx - remove those and unit should be free
Next I disconnected the pressure and return
Line at the pump.
Then remove the two upper torx screws 1 lower and (2) 1/2" nuts
The bracket with the pump still attached should slide off the 2 studs mounted to the block and head.
You will need a puller to remove the pulley to get the remaining 3 torx that mount the pump to the bracket.
Re-re pump
Press in pulley and then begin to remount bracket.
Inspect hoses and replace if required

Re: Replacing the Power Steering Pump
Thank you restopro! Couldn't get the bracket off so I checked my trusty site. I missed one of the upper torx. Great write up.

Re: Replacing the Power Steering Pump
I followed the directions in the video JRobling posted. Pretty easy. That way I didn't have to remove the alternator or the bracket they are attached to.
