1. Gather your materials.
- You will need:
- A new bottle of coolant
- A funnel
- A bucket or pan to catch the old coolant
- A pair of gloves
- Safety glasses
- A screwdriver or wrench to remove the drain plug (optional)
2. Prepare your car.
- Park your car on a level surface.
- Turn off the engine and allow it to cool down completely.
- Open the hood of your car.
3. Locate the radiator drain plug.
- The drain plug is usually located at the bottom of the radiator. It is a small, plastic or metal plug with a head that you can turn with a screwdriver or wrench.
- On some Fiesta models, the radiator drain plug is located on the bottom of the engine block. If you cannot find the drain plug on the radiator, consult your owner's manual.
4. Place a bucket or pan under the drain plug.
- This will catch the old coolant when you drain it.
5. Open the drain plug and drain the old coolant.
- Use a screwdriver or wrench to turn the drain plug counterclockwise until it comes out.
- The old coolant will begin to drain from the radiator. Allow it to drain completely.
-Close the drain plug.
6. Refill the radiator with new coolant.
-Use a funnel to add new coolant to the radiator.
- Fill the radiator to the "full" mark on the coolant reservoir.
7. Start the engine and let it run for a few minutes.
- This will circulate the new coolant throughout the system and help to remove any remaining air pockets.
8. Check the coolant level and top it off if necessary.
-After the engine has run for a few minutes, check the coolant level in the reservoir.
- If it is low, add more coolant until it reaches the "full" mark.
9. Close the hood of your car and you're done!
-Your radiator has now been flushed.
