Power steering system? Squeals and I have a rainbow slick sometimes.

Question type: Maintenance & Repair

So I'm usually on here asking about the Ford Escort
I had found on road dead but now I have a Chevy
Trailblazer 04 all wheel drive and when I turn all the
way to the left or the right with the power steering
wheel it's squeals like crazy and sometimes there's
a slick underneath the car, I keep a look on the
power steering fluid but should I consider
replacing the pump or the belts or should I try that
blue devil power steering fix stuff I've been hearing

I would look more at belt tension, if it is too loose due to a failing tensioner that could be the squealing. If that checks good then try starting the engine and have someone crank the wheel so where it starts squealing and look at the power steering pulley, if it looks like it is trying to stop it is possible that the pressure bypass valve is sticking, some of the stuff might work but if the valve bore is damaged then it wont. Is the fluid clear or does it look and smell burnt? If it looks and smells burnt try flushing the system to get as much of the fluid changed out, this will also clean the power steering gear box of burnt fluid, then see if it still squeals, if it does change out the pump.
