Capacity?

Anyone know how much power steering fluid a P-30 chassis (GM) holds?

With or without Hydroboost?

I'd take a wild guess and say about two quarts, more if you're flushing the old fluid.

I was thinking more or less the same. I bought 2 qts of the Prestone PS fluid and used a turkey baster and pulled all the fluid out of the reservoir then filled with appropriate amount. Repeated several times after driving several miles each instance of pulling & filling the reservoir until I used both quarts purchased. Fluid looks great in reservoir now.
