help 98 jeep wrangler over heating

98 jeep wrangler ck engine on and off engine over heating?

98 jeep wrangler sport with v6 automatic - Ok drove 2+ hours to cities with 1 - 20 min stop no issues on return trip home ( about 3 hours later with minimal driving in between ) after 45 minutes at 65-75 mph engine light sounds and jeep is over heating - by the time I called service guys maybe 3-4 mins temp jumped back to almost normal about 210 - 215 and light goes off. Ten minutes later same nonsense light on temp up then after backing off on speed slightly drops back down to normal and lights off - continued drive home no issues. Now this jeep has just been serviced for all obvious maintenance needs and as it over heated about 3 weeks ago the thermostat has been replaced. So whats this clutch fan thing do and fan cowling is? Yes I am not a mechanic and I'm a woman but I am tool adept if I can replace the tranny on a washing machine I can figure this out if I understand what is causing the problem. My service shop is guessing clutch fan - but then he guessed thermostat last time - I don't have time to keep guessing while jeep is in and out of shop. saw another posting with 3 suggestions 1. clutch fan 2. catalytic converter 3. radiator cap this I know is good at least thats what shop said.. Also what is the normal temp for these jeeps in 12 yrs of ownership I feel it has always run at about 210. This is a great vehicle and all my children have used it during college so I have just gotten it back and want it running sound. Any advice will be appreciated.

normal is 210-215.
How high did yours read?
Any leaks under the jeep, water pump okay?
Any leaks on the radiator?
Fluid level correct? Any air in the system?

test fan clutch, try to move it front to back. should not be able to move, if it does then consider replacing it. Fan should spin by hand but stop quickly.

will have them look at water pump but I believe they said it was fine when they did the maintenance repairs 2 weeks ago - these guys are pretty good mechanics and have serviced this jeep from day 1 - so they do know jeeps - they just seem baffled by this odd on and off over heating. But will definitely pass this on
