Ah Ya, lot's of fun. I have it to this point, so close and yet so far away.

I have the top left bolt loosened, but the lower right one.... I cannot get a socket to it, it's too shallow to allow for clearance, even with a swivel.

I can get a 1\2" box wrench on it, but the distributor doesn't allow for any travel of the wrench.

SO, I'm thinking this needs a special Z type box wrench to get to that bottom right bolt? What's the trick to this one guys?

This is the tool I beleive is needed to get to this bolt, only in the 1\2", might have to run into town today...

Got it. Med 1\2" offset, 16 bit, 1\16th of a turn at a time !!! Back together, no leaks, drips, or errors.
All temerature fluxuation stabilized, the thermostat was sticking at various positions, which explains the
temp gauge all over the place under different situations.

The heater core is next. The air warmth did increase with this thermo change, but the heater core is still not getting sufficiant flow...
