Is there a drain valve on the radiator? I took a quick look underneath and didn't see one.

 

they had to vacuum mine out of the radiator from the top im pretty sure

 

YOU WILL HAVE TO REMOVE THE PLASTIC GUARD UNDER THE FRONT BUMPER; THE VALVE IS ON THE LOWER LEFT OF THE RADIATOR; IT IS ABOUT A QUARTER SIZE PLASTIC RELEASE VALVE; IT DOESNT COME COMPLETELY OUT JUST ABOUT HAVE WAY WILL DO.
