The only major problem I've had with my 2000 XJ 4.0 is overheating. It seems to occur once a year and for different reasons, according to the mechanics.
In the last few years, I've replaced the water pump, t-stat (twice), hoses, radiator, head gasket, and of course coolant.
The other day, I drove for about 20 mins on a 92 degree day, then parked and let it run for 5-10 mins with the A/C running. The check gauges light came on and I saw the water temp was high so I immediately shut off the engine. I opened the hood, checked under the car, and no coolant had overflowed. The coolant was at a normal level in the reservoir. There was some liquid on the ground, but I believe it was condensation from running the A/C while sitting.
After letting the engine cool off for 15 mins, I tried starting it again (I was curbside at the Departures area at the airport and was getting hassled about sitting there). The started cranked, but the engine wouldn't turn over because it was still too hot.
I waited longer, started it up, and away I went with the temp gauge dropping to normal levels for the hour drive home. I haven't had a problem since, though I haven't let it sit and idle for too long.
My question is, what could have gone wrong and why would coolant not be dumped if it overheated?
Thanks!
