Hey guys, like the title says. I just finished up changing my power steering pump becuase it was leaking all over my alternator (changed that too).

So i am not sure if my old pump was bad or it was just o-rings but i changed out the pump and put new o-rings. I couldnt get the bolt off the ps pump for the high pressure line so i had to replace that was well.

I put it all back together and filled the resivour to the full cold mark, then started the car with the cap off and wheels off the ground.
I turned the wheel back and forth a good amount of times. it never bubbled up but it did eat a little fluid so i just added as neccessary.
I then turned the wheel more, it didnt take anymore fluid. by that time the car was at operating temp so i filled the resivour to full hot and figured it was all okay.

I lowered the car down off the jacks and started it. now it is rough to turn the wheel... is there a step i missed. or should i have turned the wheel more. it all seemed fine when the wheels were off the ground. but now it is rough and you can hear the whining alot when the wheels are being turned, but thats the only time you hear it.

Please help, i just finished up this "project" and now my car is still not right. kinda upsetting.
Thanks guys

to me it sounds like a bad pump. can you hear gurgling noices? and is it quite? the way i bleed them out is i start the car turn the wheel all the way to the left shut the car of and wait til the bubbles are gone then start it up and turn it to the right and do it back and forth until its blead. but the way you did it should have worked it just would have taken a little longer to get all the bubbles out.

Either a bad pump or it still has air, maybe still requires more fluid. Try doing what you've already done again, take it for a drive with some fluid in hand to top up & see how you go.

Air bubble.........

You're due for a flush anyway...probably.....do this:


Power Steering Fluid Flush:

You and 2 friends.

Jack up the front of the car and put it on jack stands so you can turn the wheels left and right.

Engine and fluids….COLD.

Put a piece of cardboard over the top of the alternator in a way that it will keep PS fluid from dripping directly onto it, but will not interfere with the pulley or serpentine belt.

Remove the hose that attaches to the bottom of the reservoir. Immediately cap that port with a vacuum port type rubber cap so the fluid doesn't pour out. You can buy assorted cap kits at the auto parts store. Or you can use a 2 foot piece of 3/8" heater hose to quickly slip on the port and just point the other end up higher than the reservoir cap so none comes out. Tape it or clamp it in place.

The hose you just removed from the reservoir.......Point it down under the car into a drain pan. This is the hose either coming from the factory cooler (if you have one).....or its coming from the rack (if you do not have the factory cooler). Either way, doesn't matter.

Have a friend hold that hose into the pan and keep his thumb over the end and wait there. The entire flush is a matter of 2 minutes.

Have another friend with 4 new OPEN bottles of PS fluid ready to start dumping it into the reservoir.

You get in the car and start the engine.

Your friend removes his finger from the hose end and lets the fluid shoot into the pan. As you turn the wheels FULL right and left "continuously" have your friend pour new fluid into the reservoir as the level drops. It could drop fast so be ready to pour. Fluid will come shooting out of the hose into the pan.

As soon as the friend holding the hose sees clean new fluid coming out into the pan.............stop the engine.
(if the friend that is pouring fluid in ever sees the reservoir about to run dry because he cannot pour it in fast enough, simply have him tell you to shut the engine off. Top it off and start the engine again. Don't let it run dry.)

Put the hose back onto the reservoir, clamp it. Top it off with PS fluid.

Your done.

CHECK to see if during this project you spilled any power steering fluid onto or into the alternator. If you did, simply drench it with WD-40 or SeaFoam spray to clean it. Then rinse it real good with hose water. Go for a 10 minute drive, take a bottle of fluid with you in case you hear any noise you can pull over immediately and top it off. Then come back and check the level one more time. Its fine to take the cap off when its hot. Top off the fluid if needed.

Not sure what this has to do with the internal engine...

I've always bled mine with the engine off as to not overly pressurize the system which can cause aeration.

Thanks for all the advice guys.
Yes the noise is very loud, but only makes noise while turning the wheel.
I took it to the auto store and they sai it's probably a bad pump and he ordered me a new one to replace it under warranty. I'll try flushing the system first before installing a new one

Hey guys thanks for all the help.
Turned out to be a bad pump. I installed the new pump the same way and it works perfectly fine. All is good for now. I go to school in a month and i hope One year from now I'll be a h/c/i w/9inch and wavetrack car.

glad you got it fixed. in my experience, the ps pumps from the parts stores are terrible quality. I went through 3 before I got one that worked in my old truck.

Couldn't agree more Rezin

Having exact same problem as described in 1st post. PS fluid leaking onto alternator. Replaced alernator, dismantled PS pump, replaced all seals within. Smooth steering after startup but now its smoking an awful lot. Not running hot, no significant fluid loss. Other than your usual oil spill burn off, could you suggest why its smoking so much? Anything else i need to check?

So I replaced the ps pump on a 08 grand prix nd instead of fixing that loud noise ..well no more noise just that now its really hard to turn..could it be the white O rings dont go there? In the pressure hose..Idk what's goin on???
