Checking actual coolant temp with a cooking thermometer and comparing it to your gauge reading would be a good start. Your engine could be needing back flushing if it is really running hot. The fan clutch could have issues also.

- '85 CJ-7, 258/4.2L 6cyl. Bought new in 1985. Full cage, Warn 8274 winch, Ford 9" rear, front/rear Detroit Lockers w/4:88 R&P. T-5 tranny and 4:1 t'case. 33X12.50-15 BFG/AT, MSD ign, on board air---
You should be use'n a 195* t'stat.
This may sound weird and bear with me............
Run a dedicated ground(GND)wire from your dash panel to the NEG(-)post of your battery.
See if the temp drops at all.
High electrical resistance(bad GND)will cause a false high temp reading. Jeep CJ's have a well known history, with this issue.
Also-Are you using a fan shroud? You really should.
You see where I live. Have the OEM cooling system and never a over-heat issue.
