Thread: power steering pump problem

Tweet

I replaced my power steering pump in my 1965 Biscayne with a fast steer box from a 1982 z-28(purchased from NAPA).

I also installed a new 1965 ps pump which makes a noise like there is air in the system.
I Turned the wheel from side to side about 30-40 times like I always do & the noise is still there.

I drove the car for the first time & the noise is still there & the wheel turns jerky.

What do you think.....bad pump or wrong pump pressure or ?

Sounds like there is still air in system

There very well could still be air in the system, though I'd bet the system pressure is your main problem.

is the belt in good shape and is it tight....ted

I think you've still got air in the system. GM has a special tool, which is really just a rubber plug to fit the PS reservoir cap nozzle, a hose barb, and a small reservoir to catch fluid. Here's a video of it in use. Bleeding your power steering - the GM way - AL, United States, AutoPro Workshop Video - Where Professionals Gather for Better Business I've heard of guys using an old cap, drilling it to fit a plastic hose barb, and then using a standard vacuum reservoir to catch fluid to keep it from sucking into the engine.

You can use an A/C vac pump too

Thanks for the info & video.......Don
