drain in the radiator located?

Hello,

The radiator drain plug is located on the bottom right inner side of the radiator (if you are facing the car), toward the engine.
It is on the same side as the upper radiator hose. Just look all the way to the bottom below the upper radiator hose, you will see the plug sticking out.

Remember to only work on the cooling system when the engine is cold.

Please let me know of any questions.

Thank you.
