Power Steering Issue
Hi all. Been a while since ive visited here. I'll get to it.
2000 Grand Am 4cyl engine. Replaced power steering pump 2x. Original one started leaking.
First replacement, the reservoir leaked, got another.
Current one has no leaks.
Problem is that daughter tells me that as the car warms up, the steering will suddenly get real tight. I have bled it more than once. Fluid will go up and down as I turn the wheels. Not sure if there is some sort of bleed screw or something.

Wanted to add, the p.s on this car is not belt driven, it's driven by the cams.

Any ideas? Thanks in advance

So it sounds like you have a 2.4 engine. Can you do a pressure test? Since the problem happens only when warm could be the pump or the steering rack.

Would the tools needed be able to be rented? Any idea how much pressure, hiw long to hold etc?
Yes it has the 2.4.

you should be able to rent the gauge. I cannt find a number, try a Hanes or Chilton manual, some libraries carry them. There is no hold number, you test with a running engine.

Well just got the pump off. Its lts not a hard job just havent had time. The pin that goes into the cam drive has sheared off. Why does this happen?


Im on my way to get another.

i would assume to prevent damage to the cams if the pump seizes

Good point. I guess it seized up. Got a new one put in. It was under warranty so didn't cost me a thing. Problem is that this is the 3rd one I get from Oreillys. I read NOT to go with a re-manufactured one, but like always... cost is an issue.
So far so good. We'll see how this one works.
