* Consult your owner's manual: This is the most reliable source. The manual will have diagrams showing the location of the drain plug.
* Look carefully at the bottom of the radiator: The plug is usually a small bolt or cap, often slightly recessed. It might be made of plastic or metal.
* Feel around the bottom of the radiator (carefully!): The drain plug will usually feel different to the touch than the surrounding metal.
Important Safety Note: Before attempting to drain your radiator, ensure the engine is completely cool to avoid burns. Also, have a drain pan ready to catch the coolant. Coolant is toxic, so handle it responsibly and dispose of it properly according to local regulations.
