My worse fear, the PS PUMP

[trainguy1989]

Well, when I was doing my motor swap I put in a remanufactured ps pump because I knew how hard it was to change it with the motor in the car. I took out the screw from the old pump that held the piece that the hose connects too and put a new o-ring(supplied with the remanufactured ps pump) on and installed it in the new pump. Now I have my engine installed and running, but discovered to my worse fear that the ps pump was leaking. It is leaking from the top of the pump where the big hose from the reservoir connects where that new o-ring was installed. The pump itself is fine. I did further investigation and saw it does not leak that bad with the car running, but once you shut off the car you can see fluid rise out of that fitting. I cannot get to the screw that hold on that fitting with the pump in the car. I really do not want to try and pull that pump and I work the rest of the week and then move to Kansas City for a new job, so I don't have a lot of time. Is there an easy fix for this? Can I RTV the crap out of it? It is leaving nice red puddles wherever I park. I used type f atf.

You could probably rtv it but it would have to be completely clean, no atf on the surfaces for it to work. Use copper rtv also.

use dexron3 or mercon type f was for the old 60s n early 70 c4 c6 n cruisamatics

I believe the spec for the SHO is actual power steering fluid.

 

[trainguy1989]

It says in my Ford Taurus Owners Guide on page 326: Use only power steering fluid that meets Ford's specification ESW-M2C33-F, such as Motorcraft Type F automatic transmission fluid or Ford Premium Power Steering Fluid(E6AZ-19582-AA).

But I don't think if I just change the fluid its going to solve the leak problem.

Type F is correct. Replace O-ring, and try again. That part is pretty easy in the car.

 

[trainguy1989]

Do you have any tips on ow to get to that bolt? From the top the rear head is in the way. From the side there is not enough clearance to get a wrench or ratchet on it.

Type F is correct. Replace O-ring, and try again. That part is pretty easy in the car.

IIRC you gotta go from under the car. Use some extensions and u joints and go up between the firewall and the engine.

From what you're saying the hose threads into a fitting that threads into the pump? I changed my hose over the summer, I forgot it was like that. If you jack the motor up you can gain access, just unbolt the rear mount and don't forget to unbolt the torque limiter.


I didn't know they specified type f. I'm wondering if I should change my fluid?

 

[kevinspann]

It seemed as though my pump was leaking from the same area. It looked like there was one bolt ont he top, that could be accessed from the top. Take out the battery and the torque limiter and you should be able to see it.

I was also curious if I had a bad pump. Does the SHO PS Pump have a back flow valve that prevents fluid from flowing backwards when the car is off? I was noticing that the pump only leaks around that o-ring if the car is off. And every time I drive it I have to bleed the PS system because air works its way back in I assume at the spot where it leaks when the car is off. I have no leaks what so ever if the car is running.

 

[tompumped]

There is a check valve in the pressure port on the rack, i'm not sure about the pump. I'm actually running without mine because it was damaged when I installed the hose with the valve improperly seated.

Help sells new teflon washers part number 82540. Although i'm not sure that's what you need.

I found this neat little ratchet device at Sears which mad it super easy to get to that bolt on top of the pump. The old o-ring was chewed up and went around town to find a replacement. I couldn't find the right size oring that would fit but found a AC oring that did. No more leaks!

Thanks guys!!!
