I checked the AC compressor and can't see any fluid, nor is there any coming off the splash shield. The majority of the puddle is almost right under the CV joint boot. It doesn't appear to be leaking. It must have all came out at one time. The only thing I remember spilling down there was a little bit of coolant from pulling off the TB coolant lines. But that should have evaporated by now and the consistency of the fluid is thicker than water, but not as thick as motor oil, more like watered down olive oil...if that makes sense.
