2012 jeep GC 3.6 engine coolant leak

2012 JGC limited 3.6 engine.

Car over heated the other day pretty good just about got it home had to stop 2 times to add water.
Every time I added water it would come out the back top side of the engine.
When I re-started yes it would come out if you look under the jeep near the fire wall the water would leak down onto the tranny and onto the ground. Im suspecting the oil cooler housing and it also has coolant running through it.
Watched many utube videos past 2 days and it seems to be the problem.

Thing Is i cant see anything as the upper and lower intake manifold is covering it up.
There is no water in the oil as I checked that or the oil cap for brown crap.

Engine runs good now that it is cool but water just pours out the top back and down.

Has anyone had this problem and could not see what it might be.
Seems the O-rings collapse and leak either oil/antifreeze or both I just see water.

Would you chance getting an after market part or an OEM as OEM is $300.00 for part alone no labor. About 2 hours to replace this is an after market.
Dealer fix is about $1200.00
