Standing in front of the car, facing it... the plug is located on the bottom right side of the radiator.... You can get to it just behind the bumper. On the stock "grill" of the lower half of the bumper, there is a dimple. This is there for access to the plug. You should invest in a Haynes maunal, before doing this on your own... You need to "burp" the system before running the car again. I can explain this, but I don't even know if you still needed help...Good Luck
