My thermostat is a 195° item, but it is supposedly a fail-safe type (all they had the day I was replacing mine). My guess is that I need to replace it and flush the system to see if something might have broken loose and is plugging a heater somewhere. I had to replace that little vacuum-operated valve that goes to the front heater core last year. Maybe a piece of that broke off and gor in someplace tight.
I wonder why these play-with-the-water projects always happen on 31° days instead of in July or August.

tk,
would suspect the vac. valve is in the hot in line to prevent hot coolant in the heater core while in A/C mode
and A/C systems only break down in the dead heat of summer when all the a/c shops are plugged and the van is supposed to go on vacation tomorrow?

I do remember before having a problem that the line opposite line with water vac into heater core stayed hot. The line coming out of the core inot heater vacuum was cold. I would have thought as you do the valve would come first to stop hot water but apparently not. I bought the van new nothing ever changed on it except by me. thanks
