Kill my power steering pump?

Was doing an oil change, checked the power steering reservoir and it was low. Didn't even have any fluid on the bottom of the stick after sitting. Never had any whining or anything from lock to lock prior to this. Steering felt fine and made no noise. The cap said Dextron ATF, I had a couple bottles of red Toyota ATF so I topped it off. It was a bit over the HOT mark after being driven, but not much. The pump is now whining constantly and varies with engine RPM. I thought maybe I overfilled it, so I sucked some out, but still whining. Did I kill the pump somehow? No leaks, just the pump whining.

Forgot to mention, the steering still feels fine. The whine just varies with the engine rpm's not from turning the wheel, even lock to lock.
 
Even if the type of fluid you added was Toyota type IV instead of Dexron I wouldn't think it would cause a problem. Maybe you spilled a little on the belt and it's slipping??
 
For what its worth Toyota type IV is not compatable with Dexron ATF according to my mechanic buddy at the dealership. I asked if I could use the Type IV in my A340 and said it would attack and kill the bands/clutches.
 
That's the only thing I could think of, that the Toyota Red fluid was not compatible with what was in there. I really only topped off a tiny bit in the reservoir. Well, I guess I'll try flushing it today was some good ol' dexron III ATF and hopefully didn't give it an early death.
 
Well, I tried flushing out the system with new Dexron III fluid, pumped a bottle through till the fluid was nice and clean, and went through almost another bottle filling it up. The whining from the pump is just as bad as before. I guess the damage has already been done. ? :ybrick:
 
how many miles on your rig, my pump went out after 230k. it was a $40 part from a wrecking yard on a 100k 4runner. had it swapped out in like 20min. just replace it, i think you ran it dry and it heated up too much, and when you put in the wrong fluid that just nailed the coffin shut...
 
Def. didn't run it dry, as it was working fine before topping it off, quiet as a mouse. Oh well. Don't have the time to track a decent one down at a wrecking yard so was going to order one off of rockauto.com. There are a bunch of options. Anyone familiar with what should be the best? The truck has 150k miles on her.

ATSCO Part # 5478 $93.79

ACDELCO Part # 36215469 $92.79

A-1 CARDONE Part # 215229 $83.79

BECK/ARNLEY Part # 1085283 $206.79 <-- obviously not going with this one. Unless there is gold inside it.

Don't really want the hassle of rebuilding my current pump, time is something I don't have much of these days.

Any recommendations on the three brands listed above?
 
AC Delco would be my choice out of those 3. I too need a new pump. I think. Mine isn't making noise, but it's still "notchy" at slow speeds.
 
Ended up ordering the CARDONE one, better warranty and produced locally in Philly. I'll let everyone know how it goes. Also, got one of their inline filters for it.

I rebuilt my pump for about $16.00, works fine now. Got my rebuild kit from pskits.com.

I bought one of those rebuild kits from pskits.com. I haven't used it yet, it's for my sisters truck, and her pump is still surviving.

How difficult was the whole process? Take it all apart and put it all back together? Just wondering if there are any tips you could give after doing it once yourself.
 
a wright up on replacing the pump!? really ok it might just be me but this is about as strait forward as changing the oil... unhook the lines (you can not mix the lines up going back on, they are different), then two or three bolts and its off, the reverse to put it back on... its not a hard swap at all, again i had mine done in like 20min(drive in drive out).

It is a very straight forward process, just make sure you pay close attention to the special markings (similar to timing marks on pulleys) as you take it apart so you put it back just like it was. This pump has steel vanes that have a round edge on one end and flat edge on the other, the flat edge goes into the rotor. I have a spare pump that I am going to rebuild, how about I start a pump rebuild thread and that way you can see the marks and how simple it really is.

Yeah, if you're tearing one apart, take pictures. Worth a thousand words, or so they say. Could save a lot of people a lot of money if they see how easy it is to rebuild them for $16.
