What is the name of an additive that could be put in a power steering pump on a Honda that would stop a squealing noise when making turns?

I Would Suggest A Product Made By LUCAS Power Steering TREATMENT. Worked Great For Me. Hey Another Thing Your Belt May Not Be Tight, Have Your Power Steering Belt Checked. If making turns causes your P.S.P to squeal, it may be low on fluid. Try adding p.s.p fluid.
