Lost Power Steering & Coolant

[btvm92]

Everything was fine, came to a stop at a turn, went to turn and immediately lost power steering, noticed battery light on as well. Pulled over and popped hood and coolant was spewing from AC compressor area? (This is a 2.7t APB). All radiator hoses were connected and my serpentine belt appeared to be fine.

Water pump seize/failure? I replaced water pump with ECS ultimate timing kit about 5k miles ago.

Battery light, power steering both have serpentine belt in common. I mean...can't you go out and just look at it to see where the coolant came from and whether the belt is still on?

My serpentine belt was still on and seemed fine, all of my radiator hoses were also still connected. What I find odd is that the coolant was spewing from what appeared to be exactly where the AC compressor is.

I tried to get a video but couldn't, but this is the location where the coolant was leaking out from.. You can see the serpentine belt appears fine.

Started it up and it runs fine, power steering is back. I poured water into the coolant reservoir and recorded where it was leaking from.

Kind of sounds like the water pump went. If it seized (briefly?) then possible you'd lose power steering and alt light would come on. Sounds like a strange situation.. They have a 'weep hole' that will let coolant drain out under certain kinds of failure.
If there ANY noise at all when running now? Can you tell if the water pump is moving any coolant? Does coolant just drain out without the engine running?
Go over all the coolant hoses and clamps that you can get to, but that particular leak does seem to come down front of the block from the pump...so, what truly happened could be moot point, since sort of looks like you have to dig into the water pump area anyway.
Only some disassembly will tell..

I checked all hoses and lines and they all look good. I can't tell yet if the water pump is moving water correctly, as soon as i pour water in it drains out of the same area immediately, whether the car is running or not. I do not hear any weird sounds like a failed water pump bearing, it is possible just the seal failed? & the leaking coolant caused the belt to slip which caused the loss of power steering and battery light?

Here is a video of my car running right now, it sounds fine, but there is no water in it.

Your problem is not as bad as you think. You have a coolant leak and the water got on the serpentine belt and caused it to slip which led to lose of power steering and alternator light. Pressurize the system and you will find your problem. I suspect a cracked coolant hose (close to the AC compressor)

Got the front end off and found a hole in one of the oil cooler hoses, the upper one. I believe it is the return hose... This one?

Well..there you go. That would definitely do it. Seeing the clip of the engine running pretty much ruled out the water pump, but I've seen them leak from the little weep-hole pretty bad...but not without the engine running.
