My antifreeze is leaking when car is not running too, I was trying to look it up with a flashlight, but all I saw was slowly leaking antifreeze from upper part of the engine, car is a Kia sephia 98, I would think it is a water pump, but I dont understand why it is leaking when car is not running. Thank you
Your just going to have to get a better look at it and positively confirm the origin of the leak. Nobody here is going to be able to tell you where it's leaking from without seeing it. Us a mirror if you need to.
