Mine never showed as leaking onto the ground I believe i've found it and will try to put high pressure hose clamps on it. On the passenger side, i've read threads on here that say the reservoir can start leaking at the seams

The most common cause of a coolant leak on the passenger side of a 6.7 cummins engine is a damaged or corroded heater core located behind the dashboard, resulting in a puddle of coolant in the footwell
Other potential sources of coolant leaks include the radiator pan gasket, drain plug, and radiator cap.
Yup new thermostat, drained orange coolant replaced with orange coolant I'm conflicted on head gaskets 1 Because i don't want to have to replace them 2 Was told the pressure test caused no leaks, leaks only when the truck is running
However i can see what i can only call a splotch of discolouration on the passenger side of the engine block but i cant determine if its. This is a 2018 international lt I've got a cummins x15 just this week, and never before, i have a coolant leak that i cannot find I smell coolant both under the hood on the passenger side and in the cab
There is no coolant smell to the exhaust or residue there
I've lost over over 2 gallons in about 10 days and can't find. That’s odd because all the coolant lines that come to mind are on the passenger side It could be migrating from the other side to that low point It’s a small leak so i would pressurize the coolant system and give it a good look around with a borescope camera before tearing anything apart.
I also herd that there is a piece of pipe with hose clamps that could be loose and leaking on the passenger side of the motor
