How do you add antifreeze? I have a 2004 Kia Optima and it has been leaking the past couple of times I’ve driven it. Does anyone have any idea what may be happening?
Put it up on a rack and look for the leak. Any other answer is purely speculation. Just before you put it up, loosen the radiator cap if it is not to hot, to allow it to leak better.
