a friend of mine has an 06 with a g56. he's leaking coolant from the rear passenger side of the engine out of a rubber connection connecting 2 hard 5/8 hose's. its a orange silicon sleeve type thing. i had the same issue on my auto but it came and went and ive now sold that truck. i think i tightend up the hose clamps if i recall correctlly. i know some other people have had the same issue on here i remember reading about a while ago. any thoughts or fixs besides tourqing the clamps
