That's also the route I am taking. I'll worry about the AC when all else is working well, as it's not much of a priority.
The final answer is froget the stupid AC and fix the ENGINES cooling system first.
I was just re-reading this thread.... how did the thermostat work out for you?

My guess is that your guage or sending unit are not accurate. If you have replaced the radiator, thermostat, and radiator cap, then your cooling system is working properly.
It takes a LOT to blow a HG on an EA81 usually. I have flogged the one in my wagon mercilessly and it comes back for more. Usually runs around the 3/4 mark when I'm off-roading. And my Brat is about the same.... I suspected the HG's and replaced them myself - since then I have had it hotter than I ever thought possible (blew a heater hose and lost ALL my coolant), and it still runs fine. It was so hot that it would not go over 30 MPH because the pinging was so bad, and the engine was smokeing from cooking the oil and dirt off the block....

Having just gone through an engine on my '84 Brat which was loosing coolent on an increasing basis, I can tell you. The coolent loss will continue to increase. Eventually, the car won't get you home. When you check the oil, it will look like a chocolate milkshake due to the water in the oil. And...this is the really bad part...the engine will have a rod knock. So if you want to avoid a major engine rebuild, address the head gasket problem before the effectiveness of the oil is compromised.

Yours is a GL-10, so you have a digidash.. its not actually getting hot, its a ground thing. Mine does the same thing.. the more electrical accessories that are on, the higher my temp gauge goes.. I added more grounds under the hood and that helped, but I finally said screw it and put an A-pillar gauge pod in with a spot for an aftermarket temp gauge.
I just installed an oil cooler a couple of days ago, and the digital temp gauge is back to it's old antics. Some time ago, the gauge would jump around by going up and then a few seconds later it would fall back down again. So what gives? I am a little concerned about this issue occurring now. Could it be that the oil cooler, which uses 3/8 oil line, is affecting oil pressure and that in turn is causing the engine to heat up sporadically?
My next step was going to be a temp sensor replacement and a thermostat replacement. I guess I should think about getting a real temp gauge too so that I can see what's really going on.

grounds usually come like this from the factory:
battery to chassis OR engine
engine to chassis
transmission to chassis
radiator to frame (more common on older cars)
inspect all these and add more in a similar fashion! that will tame your digidash abnormalities.

I still haven't added the extra grounds, but will do that soon, before the big road trip to NC.
