Coolant leak on an 08 2.9

[Jason2134]

My buddy has a 2008 Chevrolet Colorado with a 2.9 l 4 cylinder he is currently having coolant coming from under the airbox on the top of the intake manifold on the passenger side at the back trying to figure out where this leak could be coming from it definitely looks to be coming from under the back side of the air intake box close to the firewall any help would be greatly appreciated before I take it apart

There's a heater pipe there.  Comes off the driver's side of the engine, goes back and wraps around.  Its discontinued from GM.
