got the new pump tested today. If anything, it's a little worse than the old one

At 205*, I watched two little bubbles sit on the coolant in the radiator, even after I revved it up. I presume I should see more flow than that? I think this is the crux of my issues.

I got a (slightly) smaller diameter pulley from the junkyard, so I'll put that on later.

The radiator however, IS dropping temperature pretty well. I can hardly touch the top hose while the bottom hose is nice and cool.
