To find it, you'll need to:
1. Consult your vehicle's repair manual: This is the most reliable source. The manual will have diagrams showing the location of all coolant plugs and drain points.
2. Search online: Use a search engine with specifics: " [Year] [Make] [Model] 6-cylinder engine coolant drain plug location". Many forums and websites have pictures and descriptions.
3. Visually inspect the engine: Look for a large bolt or plug, often at the lowest point of the engine block, near the oil pan. It might be on the side or bottom. Be careful – the engine will be hot if recently run.
Important Safety Note: Working on a car's cooling system involves hot liquids and potential pressure. Allow the engine to cool completely before attempting any work. Wear appropriate safety gear, including gloves.
