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.

    Not a car expert, just a guy that learns how to do something when it needs to be done…

    I don’t know how relevant the “why” is… you’ve got a leak, and the easiest first step is to inspect to see if you can figure out where the leak is originating from. If you can figure it out, then fix that. If not, the next easiest might be to just replace the coolant lines. If it’s still leaking after that, it could be either the radiator or a gasket.

    Good luck!

      I haven’t been able to make it leak yet. It was suggested above to try the heater, which I have the ac on. That might be why I haven’t seen it leak, my partner always is cold.
