Burst Disk?

[gbean120]

Does the TJ have a burst disk for the A/C? I was out yesterday on a trail from Lake Arrowhead, to Big Bear in my stock LJ. After spending about 2 hours trying to clear some rock formation called the waterfall (for obvious reasons). I broke in my new rock sliders, diff guard, stearing box skid plates, and figured that was money well spent. We moved on an up the rest of the trail turned on the A/C and heard what was the equivalent of a tire bead popping.

Oh crap, I say as I realize that I am aired down to 17 psi., but there are no rocks. I turn off the LJ and look underneath. There is about a half gallon of water that is just behind the jeep. I think to myself that the factory would not put water in the radiator, so where did the water come from? Yes I know about condensation when you turn on the A/C, I am a refrigeration engineer. On my units we have a refrrigerant burst disk if the pressure gets to high. I was in a hot area, probably about 7-8000 feet, the jeep had been working really hard to get me over the waterfall, and when I looked at the engine compartment I could see a yellowish liquid that was forming a drop.

The jeep ran fine after that, and when I got home, I hit the A/C just to see if it still works and it did. I swear It took a few seconds to long to cool down, but my wife did not think so.

So my two questions. Where did the water come from, where did that fluid come from?

Any Takers? Or maybe a suggestion on what all the fluid and noise is?
