I have a 1988 wrangler and when i drive some where and shut
my jeep off the tempeture is very hot but when i'm driving it does not over heat it's at a normal temp i changed the thermastat and the fan cluth and radeator not because of the problem that i'm having now but the radiator was blocked so
i changed it and the fan clutch was shot.
I don't now if the over heating problem after i shut the jeep off is a problem are not.  

Pull your dip stick to see if you have water in the oil.  You may have a blown headgasket.  This happened to my wife's Cherokee and we had to have the head machined because it got too hot and warped.  I hope it's something cheaper like the water pump.  Warm the engine up then squeeze to hose to see if there is preasure.  Could also be loose water pump drive belt.

If I were you I'd buy one of the Repair Manuals on the market such as the one offered by Haynes.  You can get them at most auto parts stores.

Maybe your jeep has a big ego and just thinks it's hot???

nah i agree with the last guy check your oil also you have sufficient oil pressure right? Your motor does't chat like a school girl does it just a thought?

I've seen issues in certain engines where the coolant temperature appears pretty stable when driving but shoots up right after engine shut-off.  This has been narrowed down to being either (a) as heat is transferred to the coolant when driving, the thermal energy is contuinually carried away and dissipated, but when the engine is shut down (the engine is still hot, obviously) but the stationary coolant has to deal with that heat.  Result? - the coolant in the engine heats up to a higher temp that the circulating coolant would.  Same amount of heat to be transferred to the coolant, just not being carried away.  Of course this is short-term, and the engine would eventually cool to ambient temp, or (b) the response time of the sensor is such that it moderates the coolant temp reading.  Smallish temp spikes are "evened out" and are shown as a pretty stable temperature.  Perhaps a combination of both, but this is not uncommon or unheard of.

Would not a blown head gasket become evident while driving, moreso than after shutdown?  The author noted an actual temperature increase, no "boilover" or cooling system "urping", which are more symptomatic of blown head gasket.
