I have a scout II box and a crown vic pump, everything works great but the pump is whiney as hell, also the fluid is kind of milky, even after sitting overnight.. any ideas? is this normal?

New pump or P-N-P brand? My P-N-P one did the same thing and then shortly died afterwards...I think I happened to be at the Con when it did...long, noisy drive home!:mad:

PNP pump :(

Hey now! no negitive thinking! think positive :flipoff2:


anyway, anyone know of any additives to rid the whineyness?

Theirs also a cooler on the low presure return if that makes a difference

do we need to increase the size of the resivor?

because when it runs it seems low... so we fill it up...

when we turn off the engine the fluid squirts out the lil hole at the filler cap... im thinking larger res?

Milky...Normally I would think leak somewhere letting air in, but you say overnight and that should allow time for the bubbles to clear. When you are on the trail does the fluid appearance change...frothy? If not, PNP pump. I do recommend the cooler. I have an EB with Sag pump and it was noisey in the rocks. I added the cooler and it cut the noise by 3/4. Then I went to a IFS Toy box and that virtually eliminated the noise. Adding ram soon. No...not much new here...but it might help.

:rasta:

fluid also gets fairly hot... :confused:

I think pretty much all Ford pumps whine. I run an 89 mustang pump and it whines terrible also.

Yep, FORD pumps whine like crazy after a few years, My ranger did it with both of the new pumps i put on... Don't remember the brands, but one was a FORD dealer part and it whined too...

we're gunna attempt to re-bleed the system...

It sounds like you might have a restriction in you return line if your fluid is low while running and overflows when shut off. That or your reservoir is not the highest point in the system.:smokin: :beer:

Thats why i was thinking a larger res might help, so when its off the fluid will rise into the overflow res, and when its awn it will be ok...

If all of your hoses are in good shape, your fluid level shouldn't drop more than a 1/2" of so on the stick between running and engine off. It sounds like you have a pressure hose that may be ballooning causing the massive fluid drop.

brand new professional super high pressure line

foamy oil...............level drop............noisy pump...........you have air in your system.

another problem.... you said its a ford pump and a scout box..
the scout box was desighned for about 2000-2500 psi, the ford pump off a crown vic (year unknown) may be desighned for a rack.. if so.. it only puts out about 800 psi. so in otherwords, the pump thinks its hooked to a rack that is being heald at full lock all the time! you know what its like you see grandma yanking the wheel all the way over and its squeeling like crazy..

solution.. get a pump that built for the corect presure range!

Trust me that Scout box is not designed for 2500PSI, I had my stock ranger pump (R&P) on their and it kept blowing caps on the steering box which is why I went with the non-r&p crown vic pump.

Another little tid bit.. it worked fine before we threw in the cooler. I was thinking air too but I turned the wheels back and forth 40 times and then let the motor run for a while and made no noise, but as soon as you turn at all it always sounds like its at full lock.

sagnaw stering boxes used depending on aplication up to 2500 psi, most were only 2000, i curently have a valve in my pump that regulates mine to 2500, no prob.

ford used quite a bit lower presures on boxes than gm did, and the racks were calibrated for 800 psi or so... so if you were poping caps of at 800 psi, then swaped to a pump off a car that had a box (1200 psi)and its fine, then that leads me to belive that there was initialy a problem.. or the pump is bad and is hardly producing any presure what so ever. that would explane alot about it cavitating so bad.

any way you look at it tho ford pumps suck, they allways have.. if space is your big goncern, grab a pump off a tj and fab a bracket, or if you want the small pump and a remote res, grab it off a late model chev van.. it wil have the corect presure and more volume.

this is because of how a sagnaw box is set tup..
it has a valve in side it that affects boost/feal. if you arnt running enough presure, it basicly deadheads trying to use as much presure as possable , and bypasing verry little.. so now the pump is pushing as hard as it can starts to cavitate and whine..

the botom line.. the pump presure has to match the requirements of the box..

The pump first pump was off a 98 ranger /w 50k on it.. there was nothing wrong with the pump, didnt whine or anything but the caps kept popping, I was told by people on this board that the R&P pumps usually run a lot more pressure, which is why I got on from a car w/ out R&P, the crown vic was recommended. And it worked like a charm until we added the cooler, I mean it worked perfect, no whine, nothing.. thats why im pretty sure the problem is not the pump/ box combo.

Ok where exactly is the cooler located? Above or below the resorvoir? Is it located on the pressure or return line? It sounds stupid but that could be your problem.:beer:

So since my pump res is below my hydrobooster, then fluid should squirt out of the pump everytime I shut the motor off?

The cooler sites right next to the box... today I turned it on, topped it off, drove around and it was fine, quiet, steered real nice.. turn if off and fluid spills out... since other then the change in level it seems to be fine, im just going to extend the little filler thing about 5 inches or so.
