After a few weeks of use, I think my overheating is fixed. While driving with or without the AC on it's back to staying at or below 210.

Thanks to everyone for your input on this!

If I stop for 5 minutes and turn it back on, the temp on the gauge will have gone from 205 to maybe 212 or so. Seems like the coolant temp is rising from being in contact with the hot engine/head? I have never noticed this in the past. Once I run it for a few seconds, the temp goes back down.

Has anyone seen this? Is it an indication of anything?

This is normal. When you cut the car off, it still heats up but the fan isnt running and the water pump isnt circulating (heatsoak), once you start it back up the fan runs and the coolant cools back down.

for 2 years in 1980's the 4.0 had no radiator cap. does your '87 have this closed system like my '88? (no radiator cap?) My old Pioneer 4.0 liter had problem, turned out to be coolant reservoir and or/ blowout valve, the whole time. mechanic after trying almost everyyhing else, said" oh those go bad all the time" Bet i was frosted enought to cool down a D-9 Caterpillar!
