How do you bleed the cooling system on a 2001 Lincoln?

Answer 1

Here is the procedure from the factory service manual:

1. Remove the engine fill cap.

On 3.0L engines

2. Open the engine air bleed.

On all engines

3. Open the heater air bleed.

4. Add coolant to the degas bottle allowing the system to equalize until no more coolant can be added.

On 3.0L engines

5. Close the engine air bleed when coolantbegins to escape.

On all engines

6. Replace the degas bottle cap.

On 3.9L engines

CAUTION: Care must be taken to ensure the accessory drive belt does not become

contaminated with engine coolant.

7. Add as much coolant as possible to the engine fill. The heater air bleed will remain open.

8. Replace the engine fill cap.

On all engines

9. NOTE: The heater air bleed remains open.

Start the engine and turn the heater to MAX position.

10. Close the heater air bleed when a steady stream of coolant comes from it, during engine idle.

11. Allow the engine to idle for five minutes, add coolant to the degas bottle as needed to maintain the

cold fill MAX mark.

12. Reopen the heater air bleed to release any entrapped air and close again.

On 3.9L engines

13. Maintain engine speed of 2,000 rpm for 3-5 minutes or until hot air comes from the heater.

14. Return to idle and verify hot air is still coming from the heater.

On 3.0L engines

15. Maintain engine speed of 1,500 rpm for 3-5 minutes or until hot air comes from the heater.

16. Return to idle and verify hot air is still coming from the heater.

On all engines

17. Set the heater temperature setting to 24°C (75°F ) and allow the vehicle to idle for two minutes.

18. Shut the engine off and allow to cool.

19. After the engine has cooled, add coolant to the degas bottle to bring the level to the cold fill MAX

mark.
