So in the process of putting everything back together I destroyed my pressure side power steering hose. I go pissed off and didn't look at the car for a couple of days! Anyway, i got the new ps hose on. I started hosing out my coolant overflow, turned it upside down to shake it out and two big globs of redish brown goo, with the consistency of axle grease came flopping out! So, I think that at one time, the previous owner had mixed coolant types possibly. So I am going to flush the cooling system out good, then use some prestone cooling system cleaner for a couple of days, then flush her again.
