There isn't going to be one. Loosen the lower radiator hose to drain the radiator. Don't feel bad, there are plenty of people out here upset about it.


Actually that is not entirely correct. If you look from above the radiator, look hard enough to the bottom right side of it, and you should see a white "key-like" head peeping out from the rightmost lower corner. It is not easy to access it, but it is there.

I was looking for this drain plug and found this answer. On mine, it's not white and you can't see it. But you can feel it. It came out very easily once I figured out where it was, and it went in very easily. A little hard to get to; I scratched my arms up a little. Just feel around until you feel a small, flat tab-like thing. Turn it counter clockwise, and the drain plug pops out in your hand.

on the lower drivers side of the radiator on the inside is a pet cock that you unscrew to drain the radiator You have to remove the black plastic air scooper on the bottom front of the car to gain access to the drain plug I have seen two types of drain plugs : one you turn by hand or with a set of pliers The other requires a 1/4" socket driver or rachet Turn ccw ~ 1/2 turn to open
