Thanks for using Just Answer. I will be glad to assist you.
The radiator drain plug is located at the base of the radiator in the plastic bottle. Please refer to the diagram below:
By plastic bottle I mean the plastic sides to the radiator. They are called bottles.
The drain plug is on the base of the plastic bottle on the left side.
I have included a picture of your radiator below. The parts on the left and right sides of the radiator are the bottles. They are not on the bottom of the radiator but on each side of the radiator. The part that connects the bottles is called the radiator core.
Please let me know if you have any further questions about this.
