new power steering pump whine I just replaced the power steering pump on my 98 camaro ss today. I figured the whine would go away, but no what gives? And yes i just bought a tranny to replace the so called power steering pump cooler. The pump was quiet for a little while. Could the fluid be burnt? I have no idea where to go from here. Should i drain or circulate some new fluid through? Lots of question help me out guys.

reservoir? I never realized that you can bleed a pwersteering system. Is there any way to push out the old fluid with an air hose? Or would i risk blowing seals?

If i open the top of the reservoir and have someone turn the wheel back and forth, should i be able to see fluid movement inside? The pump that i took off had no movement and neither does the new pump. The new pump makes the exact same whine the pump that i took off made. Now i'm thinking obstruction. The car has 114,000 do the racks usually need to be rebuilt, it has 0 leaks.

You can use a vacuum pump or hand pump (like a Mityvac) to bleed the system, but most people just cycle the steering wheel back and forth. PSC Motorsports has a good write-up on bleeding a PS system on their site; but, if you're not seeing any fluid movement at all, I'd say there was another problem going on.

I did mine by having someone help. I drained the reservoir, unhooked the return line, and then hooked up a scrap line to the reservoir return and bent it so the end was higher than the reservoir cap. This left me with the return line free and the reservoir holding fluid. I then put that end in to a spare milk jug and raised the front wheels on jack stands.
My helper then turned on the engine, and turned the steering wheel back and forth. While all this went on, I keep the reservoir full and we stopped when the fluid ran clear. Put it all back together and repeated the procedure until the system was blead out.
This method is difficult but fast. The helper also needs to be quick and shut off the engine if you can't keep up with refilling the fluid in the tank. Running the pump dry is bad...

Its probably more the P/S fluid coming up to temp. You might try flushing it completely.

99Z71extcab,
Hey man....easiest and fastest way to do a full fluid change is with two people, or three is even better. Takes 5 minutes.
3 people:
-Put the front end in the air on jack stands so the tires can be turned left and right with the engine idling.
Take the hose off the bottom of the reservoir port (fluid return line from the rack) and have a friend simply hold it down into an oil catch pan.
-Have the second friend be ready with 4 open bottles of fluid to pour into the power steering reservoir, then you start the engine. ((from memory, I think it took 3 1/2 bottles total))
-As the level of fluid drops have that second friend start pouring in the new fluid.....while you turn the steering wheel from side to side, full left and right.
-The fluid will imediately start to shoot into the pan. As soon as that friend see's clear, new fluid, turn the engine OFF. Hook that hose back up, top off the fluid.
DONE. 5 minute job.
If you only have one friend to help like I did:
-Put the hose pointing down into the oil catch pan with a heavy vice grip hanging off the end just so it will stay spraying down into the pan when you start the engine.
-Then have the friend pour the fluid in, while he watches for clear, new fluid to spray out. Shut the engine off and button it all up.
DONE.
Obviously, get that aftermarket cooler on first. Or after I guess, doesn't matter you won't lose much fluid if you do it after. You can buy a 4 line cooler for less than that one in the link, little better cooling and fits great. Here's mine.

If you are in traffic a lot, I'd recommend getting a rail-mount coller (not what you have picked out) as its designed to work without air moving over it. (The first post in the link above has a rail cooler.)

^^^agree with that.
And "99Z71extcab"...remember, there's tens of thousands of F-Bodies running around that never got the factory PS fluid coolers installed.....so no coolers at all. And they are fine. Its good to put an aftermarket cooler on simply because heat KILLS everything. Its just something to make the pump last longer. My original factory 1998 pump is still perfect.
You can also, not a big deal, pick up a power steering fluid filter to clamp in-line to one of the rubber hoses. They're very cheap. I don't have one but I might pick one up.
Rockauto.com has them for $15.00 You can probably get them anywhere though.

So will the cooler that i allready picked up work? Great info by the way.Turned out out to be a very help full post. I think that the removal of the so called stock cooler is going to help alot. Anthing above what GM did is better than nothing. Seems to me that this is a heat related issue due to the factory installed cooler. Call me crazy but the fluid seems burnt!
