Power steering pump
« on: July 10, 2017, 03:59:41 PM »
If you didn't already know, I smoked my power steering pump at F&F due to a smashed steering stabilizer. I could not find any parts stores that can even get one. Dealer wanted $250 plus $50 core which makes me think it's a re-man. Was able to get a new pump with a lifetime warranty from Rock Auto for $125 overnighted. I'm going to flush out as much fluid as possible before installing new pump. Also want to add a cooler and inline filter. For the cooler, I'm thinking a 12" heat sink style. Thoughts? Also what filter should I get? Looks like a few different designs.

It's a sealed system. Putting a filter on it will help how?

One of our big worries was if this pump started to disintegrate and send chunks into the box. Only the filters I'm finding say to use on the low pressure side, so that won't help much.

It wont help the box at all , but it wont get back to the pump which is more delicate . PSC recommends a cooler and filter , not required , just recommended . I would think you wont flush out all the stuff like brand new parts so putting the filter in front of the new pump wont hurt.   FjR68

New pump is in. For once seemed like it was well thought out. Very easy to change. Was happy to see the  reservoir has a screen that caught quite a bit of metal flake. Cleaned that out and flushed the lines. Added a magnetic filter. Cooler will be delivered on Friday. Currently filled with ATF +4.

BUT... the new pump isn't exactly quite. Sounds like a Ford pump from the '80s. Not sure if it's because cheap aftermarket or something else is wrong. I do plan on switching to Lucas fluid after installing the cooler. Not sure if that will help.

Probably air in the system, cycle it lock to lock a few times, it should quiet down.

It's tiny air bubbles in the fluid for sure.
It takes awhile to work them out.
                                                  Your pump whipped the fluid into a froth.
I very slowly and carefully poured small amounts or degassed fluid a little at a time.
Started it, just to suck it in., stopped let it, sit a long time, added more, let it sit even more.
Try de-gassing the fluid by letting it sit still open for a long time.
Noooo little bubbles.

Sounds good. I'll give that a try

Drained out most of the fluid. Added Lucas fluid as instructed above. Jacked up front end, did lock to lock with engine off 40 times. Added more degassed fluid. Started engine. Did more lock to lock...
