Power Steering Leak (57 thunderbird)
Howdy Fellas
Having an issue with ATF pushing out around the cap on my reservoir under acceleration. The can was resealed a few years ago and hasn't had any issues until lately. At idle it's fine, but once engine speed increases it starts seeping out. The control valve was replaced a couple of years ago due to a bad leak with a rebuilt unit from concourse parts. Never had an issue with over pressurization. Fluid level is correct and not overfilled. It doesn't appear to leak when the wheel is turned, just with engine sped up. Link to video below. Thoughts? https://youtu.be/DC0oJIFc9jI

Re: Power Steering Leak (57 thunderbird)
1) Does the filler cap have a gasket? I can't remember ...
2) Plugged filter 3) Pump pressure relief valve defective 4) Restriction in pressure side of system

Re: Power Steering Leak (57 thunderbird)
I bought a 64 Tbird once and there was no filter in reservoir and it leaked like that. After I found a filter it quit. As to why yours would just start leaking is a mystery to me, in the video it looks like the belt to it is a little loose, may have just been the view.

I have a filter in there. Was replaced when can was resealed. I tend to leave belts a little on the looser side to keep from loading up bearings on accessories. Nothing squeals so should be ok.

It's a pretty snug fit putting it on. Last edited by dmsfrr; 04-18-2021 at 05:12 PM. |

Re: Power Steering Leak (57 thunderbird)
You need to have a pressure gauge to isolate the problem. The procedure is fully described in the SHOP MANUAL. Better to analyze it rather than throw parts at it ($$$).

Re: Power Steering Leak (57 thunderbird)
I did notice pump didn't sound stressed. Completely forgot there were pressure tests. Maybe a test to diagnose a stick valve as suggested but I have no idea where a person would have it done or buy the tools.

Re: Power Steering Leak (57 thunderbird)
Also, here is a tutorial that will help explain the procedure(s).

Re: Power Steering Leak (57 thunderbird)
You're more than welcome.
That is only a basic tutorial and can get more involved on later model cars. But for an EATON PUMP/BENDIX STEERING it is very basic. Another consideration would be a cooler depending on how hot the fluid gets.

Re: Power Steering Leak (57 thunderbird)
dmsffr — you had the fix. My cap wasn't as tight as it should've been. I gently bent the tabs up on the cap and it fits a lot snugger now. No more leaks!
Thanks to all who chimed in. Appreciate all the helpful folks on this site. |

Re: Power Steering Leak (57 thunderbird)
Mine had been on for a coupe of years now with no issues, but it is always to have access to good videos, just in case.
