Are you sure that you reconnected the hoses properly? Are the hoses properly routed? Are there any kinks in the hoses? Did you use the proper fluid? I would send the pump back to Chockostang before I bought another pump.

Yes, Iām sure. It was returned with the hoses installed. Type F motorcraft fluid is what I used. No kinks at all.
Worked fine for about a month, maybe 4 times out. Sped the engine up to 5k rpm, like normal and thatās when I noticed it didnāt like that. Started to feel tight around corners.
Dans explanation was confusing but it was something like dirt could have gotten into to it and needed to be inspected. Not sure how that is even possible with everything being new or rebuilt to be new.
Odd that the old dirty fluid that was in there for 35 years is what I was using for the last 5 years and that stuff worked perfect. Maybe because it was being replaced with new stuff constantly. Idk. Thanks for your thoughts.

Is the belt slipping? Sounds like it
You mean I shouldnāt have greased the belt?
Everything is like I left it 3 weeks ago. I decided to pull it out tonight, just to listen to it purr. If I canāt get together with my Napa guy soon, I might be forced to open it up myself. I mean-if one man can do it, I will too.

If you havenāt already done it, Iād suggest you jack up the front end to get the wheels off the ground then start engine and go lock to lock with steering several times with no load on front end. If you had junk in control valve or air lock, this might help. Loose belt shows with no load too. Iāve struggled at times getting mine tight enough. Just seems odd a fresh pump would fail as they ere pretty simple and reliable.
Thank you the suggestion. Sometimes it takes me longer to realize your questions are meant to help. Appreciate it!
That was the first thing I checked when it started acting up, followed by checking fluid level.
Although, I did that when I filled and bled it the first time. Figured Iād go try your suggestion, this morning. Went lock to lock 15 times.
Still nothingā¦belt, pulley and pump shaft are spinning and fluid is cold.
Does cold fluid indicate the pump isnāt working? Is there a way to know if it is not the control valve?
At this point Iād be looking in my factory shop manual to see their test suggestions. A quick thing you could do would be check dipstick with engine off then again at idle as prescribed. You should see a difference if it circulating- donāt know if you could peek in dipstick tube with a light for movement/froth. Iāve overfilled before and it comes out tube at a pretty high rate making a mess in a hurry. Temp, I donāt know it will heat from circulation plus from manifold heat. Hope you sort it out.
Thank you, it is good to know that Iāve already read the power steering section many times before and since this happened. I just didnāt notice any trouble guide.
My Napa friend was in for a little bit yesterday, but I missed him. At this point, Iām really just hoping he gets better and can enjoy some free time. He has helped me since the beginning with certain parts on this cougar, as he has redone a couple of them. I just donāt want to jump on him when and if he returns.
I do have a couple other resources near me, who have extensive Mustang experience. One said go to Napa and the older more experienced one said to send it back.
It is probably more likely I did something wrong to cause this. Iām not going to send it back to make it his problem.
I appreciate your time with this.
New pump is on order for $300 3yr/36000 mile warranty. I went to Motion Auto. They are local 75yrs in business. Tonya I have know for many years works there and she has a 289 in her truck. She also had a brown 71 cougar in high school.
I will then have time to take my pump apart and hopefully fix it.
Not sure why I forgot to mention, I always check WCCC, first. Iāve never personally been there, but, Don Rush, to me, is #1. If they donāt have what I need, Iāll look elsewhere.

New pump came in and first thing I tried was turning the pump shaft. Smooth as butter-made in china.
When I sent out my original pump, it felt the same way-smooth as butter.
Fist thing I did when I got my pump back from Chocko was turn the shaft and of course it felt bumpy-exactly like a bad bearing. Iām not a pump expert although Iām getting ready to be!
Forgot to mention I found a 77ā cougar 351 at the junk yard. Took out the power steering pump and bought it for $20. Turning the pulley, it is smooth as butter, also. One step closer to a working car.
The original pumps feel exactly like you describe when you turn the shaft. Itās not a bad bearing, itās the internal pump. If they feel smooth as butter, they arenāt developing much pump pressure. The guys at Chockostang are pump experts, and my advice would be to stick with them. They will get it right.

Oh no, Iāll be the one this time, to get it right
Mr-580, I see the test procedures up front, now-thanks. I donāt have a 2000 psi gauge to check the pump. To start the test, it says to warm up the fluid by starting the car. My fluid didnāt warm up so itās ok I bypassed that.
I put the new pump on and everything works as it should, with no leaks. We will see how long it will work like this. I am still curious what went wrong with my original pump, so thatās next.
