The power steering, @TLAR went over what to replace on a website he recommends - very impressed. I’ll opt for a $100 more costly option, that basically, unbolts the PS unit and everything out to the tie rods at the wheels: $256. If I had two cars I could drive, would go the Tom suggested and maybe learn a bit more about PS. But This way, I know when I put it up on the lift, I can get it all put back in easy, fast, and every will function as all the pieces are assembled.
When I get another driver, will pull head, have surfaced and probably redo the valves since its off. But that requires the car t be down a couple days. If I can find a rebuilt head with the valves redone, will do that since it’ll need doing anyway (180k+).
As far as overheating, I can drive it 70 - 100 miles before I need to add coolant. Thing has cross-flow radiator, hate those things, as you lose coolant the ability cool goes down and accelerates. But hood line does allow downflow to fit properly is my guess.
But hey - free cars are always the most expensive!
Lots other rattles and noises to chase down - which is saying something since my hearing ain’t so good.
