first head gasket job... still hot..
If it heated up idling, likely not a plugged up radiator. Actually sounds more like a defective thermostat. Try it without the thermostat. Put the top radiator hose directly on the manifold outlet, replace the thermostat with a splice bushing from Advance Radiator Hose repair kit (about $5). Leave the expansion tank cap slightly loose so pressure will not build. Rev the engine to about 1500 to 2000 rpm, that should push the coolant through the heater core and get the air out.
Disco's without thermostats typically run about 175, but warm up slower than normal. If it does not overheat without the thermostat, you can start putting it back together with a thermostat.

Hey guys, thanks for your help. I got a laser temp gauge yesterday and re-bled the coolant system. I didn't take my time when I first bled it and definitely had some air in the system. It started up and stayed cool for 15 minutes so I thought it safe to drive several miles pull over snd check temps again. It stayed cool.. what a relief. Is the Ultragauge an in-cab type temp gauge I can watch all the time? I still would like to have piece of mind every time I am in it.

You can get the wired UltraGauge as saturnine stated or the UltraGauge Blue that’s connects via Bluetooth to your smartphone or tablet.

x2. True story. Gotta get that front end lifted. Its surprising how much a difference it makes. Lift that front end and lift the bottle.

Just Curious. Seems to me that with LR cooling issues being so prevalent here,water pumps, head gaskets, thermostats and what-not, that a coolant system vacuum bleeder would be as common to the tool kits as is a 36mm wrench.
I've never seen anybody mention using one. It's nearly always the park up hill or lift the coolant tank method.
