Here's a general procedure. Specific locations of components might vary slightly depending on the engine (3.8L V6, 4.6L V8, etc.). Consult your owner's manual for the most accurate information specific to your Mustang's engine.
1. Prepare for Draining:
* Gather Supplies: You'll need a drain pan (large enough to hold several quarts of coolant), a wrench (possibly a socket wrench) to remove the petcock or drain plug, and potentially some rags or towels to clean up spills. Consider wearing gloves to protect your hands from the coolant.
2. Locate the Drain Petcock or Plug:
* Radiator Drain Petcock: Most likely, your radiator will have a petcock (a small valve) located at the bottom of the radiator, usually on the driver's side.
* Radiator Drain Plug: Less common, some radiators might have a drain plug instead of a petcock. This is usually a bolt or screw.
3. Open the Drain:
* Petcock: Carefully turn the petcock counterclockwise to open it. The coolant will begin to flow out.
* Drain Plug: Carefully loosen and remove the drain plug using the appropriate wrench. Be prepared for a sudden flow of coolant.
4. Drain the Coolant:
* Place your drain pan under the drain petcock/plug to catch the coolant. Allow the coolant to drain completely. This might take some time.
5. Close the Drain:
* Petcock: Once the coolant has stopped flowing, carefully close the petcock by turning it clockwise.
* Drain Plug: Carefully reinstall the drain plug and tighten it securely.
6. Optional: Drain the Engine Block: The engine block also contains coolant. You might want to drain this as well for a more thorough flush. This is often done via a drain plug near the bottom of the engine. Refer to your owner's manual for the location of this drain plug, as its location varies by engine.
7. Dispose of Coolant Properly: Coolant is toxic and should be disposed of properly. Check with your local waste disposal authority for guidelines on how to do this. Many auto parts stores also accept used coolant for recycling.
Important Considerations:
* Pressure: The radiator might still be under some pressure even after the engine has cooled down. Opening the petcock or plug too quickly can result in a sudden burst of hot coolant. Proceed carefully.
* Coolant Type: Note the type of coolant you drained (usually indicated on the container you refill with). This will be important for refilling with the correct coolant.
* Safety: Always wear appropriate safety gear, including gloves and eye protection. Coolant is corrosive and can cause skin irritation. Work in a well-ventilated area.
