Well, have I got a story for you.
Out and about yesterday doing some good old fashioned bush bashing and the radiator boiled.

The track wasn't that tough, I didn't need to use 4wd but we were pushing down scrub to get through.

There were no indications of any problems. It was about 6 pm, the outside air temp was 15°c. I had to stop the car to shift some branches. The moment I turned it off I could hear the radiator boiling. As I have only recently purchased the jeep I was unfamiliar with the overheating issues. Besides, we weren't working hard.

Anyway I jumped back in to start the car, which it did, and then died. After that it just wouldn't start. So then I started to think there was something else wrong. The first thing I checked was if the was any spark at the plugs. Nothing. Then I checked the coil. Nothing. Then I went to the uhf radio and called for help. Oh well.
After I had calmed down while waiting for the support team to arrive, I realized that the electric fan wasn't running.

Also the temperature guage was sitting just under 100°c.

So, where does one start?

And just to make the mystery even more mysterious, I had the other vehicle go back up hill, find a spot to turn around and reverse back down the hill so we could tow the jeep back up so the support team wouldn't have as far to go. So after hooking up the tow straps I jumped into the jeep and thought I would try and start the motor, and you probably guessed it, it started!

So a quick fix was to cut the wires to the electric fan and connect it directly to the battery so it was running constantly on the way back home. Which wouldn't have been a problem in the day. By now it was 9 pm and 8°c.

Even with the internal heater turned on full the air was cold. And still the temperature guage hovered around just under the 100 mark until we got closer to home and it got a bit cooler, it stayed just above 85°c.

So what's the source of the problem?
