Draining and Filling

1. With the engine OFF and sufficiently cool, remove pressure relief cap, open radiator draincock and remove the cylinder block drain plugs and allow coolant to drain.
2. lose radiator draincock. Hand-tighten.
3. Check all hose clamps for proper tightness and location. Make sure radiator draincock is closed and cylinder drain plugs are installed.
4. Remove heater water hose from heater outlet tube at rear of RH cylinder head.
5. Fill degas bottle with a 50/50 mixture of Ford Premium Cooling System Fluid E2FZ-19549-AA (green), Ford Extended Life Engine Coolant F6AZ-19544-AA (orange), or equivalent and water until the mixture flows out of the heater outlet tube.

NOTE: Its important to maintain engine coolant concentration between 40 percent, -24° C (-11° F) and 60 percent, -52° C (-62° F) depending on climate conditions. Below 40 percent, there is a loss of freeze protection. Above 60 percent, the engine may overheat on a warm day. Outside this range, protection against rust and corrosion may be greatly reduced.

6. Install heater water hose to heater outlet tube. Install hose clamp securely.
7. Fill degas bottle to below the filler neck seat with a 50/50 mixture of specified coolant and water.
8. Place heater temperature selector in MAXIMUM heat position.
9. Install the pressure relief cap and run engine until water thermostat opens (coolant flowing through upper radiator hose becomes hot).

WARNING: TO AVOID THE POSSIBILITY OF PERSONAL INJURY OR DAMAGE TO THE VEHICLE, DO NOT OPERATE ENGINE WITH HOOD OPEN UNTIL FAN BLADE HAS BEEN FIRST EXAMINED FOR POSSIBLE CRACKS AND SEPARATION.

10. Stop engine and allow to cool. Carefully remove pressure relief cap.
11. Add a 50/50 mixture of Ford Premium Cooling System Fluid E2FZ-19549-AA (green), Ford Extended Life Engine Coolant F6AZ-19544-AA (orange), or equivalent and water to the COLD FULL LEVEL mark on the degas bottle through the filler opening at the top of the degas bottle.
12. Install pressure relief cap. Check for leaks.
