Coolant leak from back of engine
We have a 2013 GL550 with 103k miles and has started leaking a significant amount of coolant from the rear of the engine. It is dripping beyond the covers underneath towards the drivers side. I have tried to see where it is coming from but I am having trouble. I took it to a local shop that used a camera and the lift and thinks the leak is coming from somewhere near the intercooler but without removing the intake they are not sure. I tried searching the forums and I do not find any threads related to this type of leak. I know I am not giving much info but does anyone have any idea which pipe this could be or if something in the area is a common area for this leak? thank you.

I replaced a connection last year after finding a leak in this location, it was a quick and cheap fix
