    Hi pmarshall,

    It's located at the bottom of one of the radiator's side tanks (not sure which one). Turn it to allow the coolant to drain. Turn it counterclockwise all the way - don't stop half-way and allow the pin on the drain plug to come into alignment with the slot in the bore, as the plug might come out and you'd wind up with a mess. to clean up!

    Be sure to wait until the engine/cooling system is completely cool before draining the coolant.
