2012 Ford Focus, 155K miles, it is leaking a decent amount of coolant when my partner drives it to work but doesn’t even leak a drop if I drive it to work. The mileage is the same but I don’t sit in traffic. Could the extra heat from sitting in traffic be opening up a pinhole sized leak in the coolant line?

Edit: Thanks to a tip from the comments when the heat is turned on it leaks. I should be able to bypass that line pretty easy.

Thanks Kolgeirr@sh.itjust.works

    This seems like the best option. That or stop and go traffic is causing the coolant to over flow and leak out. Possible cooling fan issues if the problem is only in stop and go traffic whereas on the highway at constant speed it’s fine.
