W30olds Posted April 17, 2018 Report Share Posted April 17, 2018 Hey guys. So I need to replace my leaky PS pump on my 95 GP. Have a question. How's the easiest way to get the lower hose nut off that thing? The one that's behind the plastic resovior below the rubber hose. The hard piped one. Stubby wrench perhaps?? The rest seem pretty straight forward. So if there's any tricks you can pass along on changing it out please let me know! Thanks Sent from my SM-G900V using Tapatalk Quote Link to comment Share on other sites More sharing options...
mfewtrail Posted April 17, 2018 Report Share Posted April 17, 2018 I'm assuming you have a 3100? If so, a standard length wrench should work as there should be plenty of room to work with. Flare nut wrenches are what you're supposed to use on line fittings like that by the way. W30olds 1 Quote Link to comment Share on other sites More sharing options...

I do have a set of line wrenches that I'll use on the metal line. Going to replace it hopefully Saturday weather permitting.

W30olds Posted April 20, 2018 Author Report Share Posted April 20, 2018 I ordered up a pump w/resovior from GM. Got a buddy who work at a GM dealer so I got the pump at his employee price. Pretty freaking sweet! So whenever it comes in I'll be swapping it out. Be nice to get the old leaky one out of there. It's starting to leak on the serpentine belt and throw fluid all over the passenger side engine bay. Nice.

Imp558 Posted April 20, 2018 Report Share Posted April 20, 2018 It's likely just a leaky reservoir, a couple clips and the pump and reservoir are two pieces. Keep either the pump or reservoir in a big Ziploc bag for when you need it. Saving a few bucks. W30olds 1 Quote Link to comment Share on other sites More sharing options...

Imp558 Posted April 21, 2018 Report Share Posted April 21, 2018 The reservoir was the leak on the Monte Carlo. Now hopefully the pump is bad because it lost power steering. It should be in today. W30olds 1 Quote Link to comment Share on other sites More sharing options...

It should be in today.I'm sure mines leaking from the reservoir also. It's the original PS pump, so I've gotten 23 years out of it. Can't complain. However it was only a few more bucks to get it with a reservoir already on it so I said what the hell. Hope you get yours fixed!

55trucker Posted April 22, 2018 Report Share Posted April 22, 2018 There is an O-ring around the reservoir nipple that fits into the pump housing, it won't last forever, 50cents for an O-ring is a lot less to spend than one would on a complete pump assembly..

Just talked to Autozone and have a seal kit ordered. $12 buck for it. Thanks for letting me know this. The pump works fine but is leaking. I'll take it apart and replace the seals. Way cheaper than a new pump! Will be calling GM and cancelling my SO pump. Now to figure out the weird starting when hot thing......

55trucker Posted April 22, 2018 Report Share Posted April 22, 2018 If you decide to go this far, to get the shaft seal out you'll need to protect the exposed portion of the shaft to prevent damage to it while forcing out the seal. In the past I've used a short length of shimstock...0.20 thou., surround the shaft & press it down into & past the seal lip then with a center punch make a small hole in the body of the seal & use small tapered round prybar to work out the seal.

I'm assuming I'm gonna have to take the pump out of the car? If so while it's out I'm going to see where the things leaking. I'm pretty sure it's leaking from a seal in the plastic reservoir. Mainly because the fluid appears to be coming from around where the lines come into the housing.

Imp558 Posted April 22, 2018 Report Share Posted April 22, 2018 Replaced this one today, it was the most broken PS pump I've ever seen. The shaft was broken and the pulley with half of a shaft fell out in my hand. It was easier to remove from the car in two pieces so that was cool. Had to rock the engine to get the replacement back in. Galaxie500XL and W30olds 2 Quote Link to comment Share on other sites More sharing options...
W30olds Posted April 23, 2018 Author Report Share Posted April 23, 2018 I took the PS pump assembly off a little while ago. Took off the reservoir and where it went on to the pump there's was no o-ring. So I'm pretty sure that's why it was leaking. That's the only place I saw. Installed new o-ring and reinstalled the reservoir. Put back onto the car and so far no leaks! While in there put a new serpentine belt on too. Thanks guys for giving me the info on the o-ring. Saved me a good amount of cash. You guys rock! Sent from my SM-G900V using Tapatalk Quote Link to comment Share on other sites More sharing options...
55trucker Posted April 23, 2018 Report Share Posted April 23, 2018 begs the question..... what happen to the original O-ring? Quote Link to comment Share on other sites More sharing options...

Galaxie500XL Posted April 24, 2018 Report Share Posted April 24, 2018 Never seen one that bad...though I did actually have that pulley on the power steering pump on the Cutlass actually fracture..that center portion of the pulley is actually plastic on the LQ1, and I’d assume most everything else GM made around that time. Made a horrible noise. Quote Link to comment Share on other sites More sharing options...
