I live in "realville" "If the Emperior has no clothes.......!"
"designed and built almost 45years ago and expecting it to perform like a new vehicle?"
If it were built in 1920's., it should still perform well.! People drove those old rigs 3000 mi. across the USA on dirt/mud/rain/up-n-down hilly wagon trails, in the heat..!
The only real improvement over the 60's vehicles & now, would be electronics & "the jury is still out" on that...
I feel the same as you.... I'd want to (at least) know what's causing that. More likely I'd keep poking/testing 'til I found the culprit.
Ya., 180 up to 200 & back down....prob. not a big deal, but I'd be ****** if it started going over 200.
It's poss. the rad. internals are caked enough to "insulate" & not allow good heat transfer.... but still pass water. (the fan blowing on it & helping is a clue)
It's poss. to get a "bad" t-stat these days as well.
I had a '70 Land Cruiser (with that 'lil grill)...it had a chevy 350 stuffed in it & it ran 180 day/night/winter/summer/up-n-down hills/slo-n-go...etc.
I hate to tell ya to spend more $$ but maybe, as you said, a new rad. is in order.
(BTW., is that an AUTO or STICK.?)
You've been helpful on this board & as you know, W/O "laying an eyeball" :-B on these things.....it's really a guessing game.
