Overheating.. and THANK YOU VERY MUCH!

Okay, not trying to hijack the thread, but might be relevant to your situation as well. Mine is doing the same thing. Runs steady as a rock for about 30 minutes & then the temp shoots up. Found out the electric fans were shutting off. If I turn the Disco off wait about a minute, they run fine again. No idea why, but they are doing it. Leave teh AC off & even at 101d and it runs fine. Relay maybe??

If you are going slow and electric fans off, then that could be part of the problem. If going highway speed then it is more than that. The fan relay is switched on by the fan switch for HVAC on the dash applying a ground. Try wiggling switch. May have to remove some dash plastic and electronic spray clean the switch. On a D1 at your miles may want to consider boil and rod out of radiator, about $70 near me at indy shops. And I'll go ahead and put in a plug for the 180F thermostat, a great $10 upgrade IMHO.

I might as well update where I'm at with it, so others can benefit, if possible.
After replacing the thermostat for a 180d unit, cleaning-out the crud between the radiator and the condenser, flushing the cooling system with a detergent flush and replacing with antifreeze / water-wetter / water (per recommendations), it was still getting way too hot, most particularly after a freeway blast and then stop-n-go on the surface streets.
I finally decided I was going to pull the radiator and have it gone-through at my local radiator shop. I figured I'd replace the fan-clutch while I was at it. A scheduling issue meant I couldn't get to it when I wanted to, but since replacing the fan-clutch is only a 20 minute job, I decided to get it done one afternoon.
fixed the problem. NO more overheating whatsoever.
so that was probably it all along, even though it seemed to pass the "should spin / shouldn't spin tests.
I'll still need to pull the radiator some day soon (if I keep this POS) because I've got a little weep on the right-side tank, at the trans-fitting.

Maybe because it only overheats when the A/C is running, and so one needs to runt he A/C to determine if the steps one has taken have improved the situation.
