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.

    Inside hood is clean. The coolant hoses though look and feel like they are near the end of their life. I’ve not located where the leak is occurring, no signs of fluid on the engine block. The puddle I saw was next to the inside of the front right tire, under the coolant tank. I checked and it’s leak free.

    I added some stop leak to see if that solves it for now. Car only has to last another six months before we replace it and my teenager gets to deal with it.

        Best way to learn how to work on a car, is to have a car that needs to be worked on.
