When heater is on, some coolant leaks from an area by the firewall and dripping on the transmission and hoses/wires near by. I checked a video that said you can drop the transmission to replace a small hose and which hard to get to from top and bottom. I do not know if he was being facetious or just want to be a "youtuber" did not know how to do it. I could not visualized the hose that is leaking but leaks when heater is on and suspected one of the heater hoses. I do not know the exact location nor how they run to be able to tackle the issue. Any ideas would be appreciated 2012 c250 1.8 turbo
