Well, we found that the T-coolant line had been worked on in the past as it had hardware store hose clamps on it. The UV dye highlighted the area so we took off the throttle body from the intake manifold and got access to it. The T-fitting that was on there just literally disintegrated just touching and in fact while getting a new one from the hardware store shattered even more in my pocket.

So there is that.

Right now I am trying to ascertain if that was it. As mentioned, a bunch of coolant/water did get on top of the valley pan cover and even after a couple days now is still producing steam when the engine is stopped after driving that it didn't do before.

Or the water is pooled on the skid plate or something.

It only produces steam when the car isn't moving and not for long but still unsettling as it does make its way into the cabin as the cabin air intake is on that side of the vehicle.

Oh, and I did just pop the hood and cannot see any further leaks or issue. Even the belt squeal has gone away. So I am hoping that whatever water/coolant will also evaporate away after time.

Just a word of warning, we had a coolant leak that took me a while to find, one of the brand new hoses I installed was bad, and it was dripping right on the belt. I actually never got a low coolant warning it was so slow, it was the belt squeal that was the trigger something was wrong. I replaced the belt, still squealed. Finally saw the coolant sitting on it one morning. Fixed leak, cleaned belt, still would squeal on cold mornings.

Just saying be prepared for maybe needing a new belt once leaks are addressed. Belts tolerate oil much better than coolant.
