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

Huh, didn't know that. Most of my wrenching has been done on older GM trucks and they used a vacuum actuated valve that cut the heater core out entirely by closing the loop under the hood, so coolant still flows by a shortened path. I'm just glad ops problem was found there. Thanks for the info!
