Flushing - Radiator Installed

1. Disconnect the battery ground cable.
2. Drain the cooling system.

NOTE: Do not use a galvanized container if the coolant is going to be reused.

3. Remove the water thermostat and reinstall the thermostat housing.
4. Disconnect the radiator coolant recovery reservoir hose from the radiator coolant recovery reservoir and plug the end of the radiator coolant recovery reservoir hose.
5. Disconnect the heater water hoses.





6. Connect the two heater water hose ends, bypassing the heater core.
7. Remove the lower radiator hose from the radiator.
8. Connect a high-pressure water hose to the lower radiator hose. Back-flush the radiator and engine until clear water runs out of the radiator lower hose connection.
9. Install the water thermostat with a new housing O-ring gasket.
10. Reconnect all cooling system connections.

CAUTION: Make sure that hose clamps are beyond the bead and centered on the sealing surface. Do not reuse hose clamps; use a new clamp to insure proper sealing.

11. Connect the battery ground cable.

With the entire cooling system drained, the following procedure should be used to be sure of a complete fill.

12. Close the radiator draincock. With the engine off, add a 50/50 mix of Ford Premium Cooling System Fluid E2FZ-19549-A or -B. or equivalent meeting Ford specification ESE-M97B44-A and water.

CAUTION: Less than 35 percent, approximately 2 liters (2.1 quarts), or coolant concentrate at -16° C (4° F) may cause engine corrosion and overheating.

13. Install the radiator filler cap on the water hose connection only to the first stop (non-pressurizing). Start the engine and run at fast idle until the upper radiator hose feels warm, indicating the water thermostat has opened.
14. Remove the radiator filler cap and top off the coolant level with the specified coolant/water 50/50 mixture. The total cooling system capacity is 7.5L (7.9 qts).
15. Securely install the radiator filler cap on the water hose connection with the engine running.





16. Fill the radiator coolant recovery reservoir with the specified coolant/water 50/50 mixture until the coolant level reaches the F mark on the coolant level dipstick.
17. Check the cooling system components for leaks.
