When I was fiddling around with it yesterday, I swapped the new 195* T-stat back in and burped the system. When I refill, I usually have everything but the top radiator hose buttoned up, and I pour coolant in the radiator steadily until it stops going down. Then I do the same with the water neck of the T-stat housing and I squeeze the bottom radiator hose to burp a lot of the air out of the block. Refill the radiator again, secure the top radiator hose to the T-stat housing, then fill the radiator some more and burp more air by squeezing the top radiator hose. Been doin' it this way for years and it seems to get the majority of the air out in the first go. I also make sure to use T-stats with the little bleeder valve on 'em and make sure it's positioned toward the top when I install it in the housing so the air can burp out.
I didn't see any bubbles appearing in the coolant, just a lot of crumbly sediment still lingering around in there that the flush didn't take care of (or that's still working itself loose from the radiator). I had it running with the cap off for awhile - maybe 5 minutes - although I didn't let it get it up to full operating temp ... roughly only 1/2 to temp. Still no oil or anything weird in the coolant, or any milkshake on the dipstick or oil cap, just that damned grainy rust sediment that's still plugging things up. I hope to heck I don't have a plugged passage somewhere in the head(s) or block...
It's getting a 3-core radiator thrown in, regardless of whether the current one is the primary cause or not. Out here in AZ, Foxes NEED a 3-core copper/brass radiator at a minimum. The one that's in there is better suited for use with a four-banger.
