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
So you are breaking the heater in your car and removing the defroster a safety feature? Just replace the heater core…
This is to get it to stop leaking coolant until I can change the heater core.
