Dealing with a few coolant leaks in my sons 2010 RS. Just finished replacing radiator and water outlet gaskets. After the install of those, I re-pressure tested and I could see coolant leaking down the rear of the engine, between bellhousing and rear of block.
Thinking possibly the thermostat housing? Are there other coolant passages up on the back of the engine that would leak? Attaching a pic (have to forgive the picture quality, trying to get two hands back there to put light on it and get phone in there for a pic was…. Not easy)
My only other thought would be head gasket based on leak location.
I used a die test to be able to highlight the coolant with UV light.
Thanks for any insight anyone could provide
