Draining and Filling

1. Bring engine to normal operating temperature and turn engine off. With cooling system under pressure, inspect cooling system hoses and clamped hose connections for leaks, excessive deterioration or contact wear. Inspect radiator installation retention. Note any discrepancies and proceed.
2. Drain engine coolant as follows:
- Switch the engine off and wait until cool. If radiator is still hot, carefully wrap a thick cloth around the radiator cap and rotate slowly to the first stop. Step back until the pressure is released.
- Then press down on the radiator cap and rotate until free. Remove the radiator cap.
- Open radiator draincock to drain the coolant system.
- Disconnect radiator overflow hose from radiator filler neck connection. Remove radiator coolant recovery reservoir and empty the fluid. Flush radiator coolant recovery reservoir with clean water. Drain and reinstall radiator coolant recovery reservoir and radiator overflow hose and clamp to radiator filler neck.
- Correct, service or replace any components found to be malfunctioning in Step 1.

WARNING:
- NEVER REMOVE RADIATOR CAP OR COOLING SYSTEM CAP UNDER ANY CONDITIONS WHILE ENGINE IS OPERATING. FAILURE TO FOLLOW THESE INSTRUCTIONS COULD RESULT IN PERSONAL INJURY AND/OR DAMAGE TO THE COOLING SYSTEM OR ENGINE.
- TO AVOID BURNS FROM SCALDING COOLANT OR STEAM, USE EXTREME CARE WHEN REMOVING THE RADIATOR CAP.

3. Refill engine cooling system as follows:
- Close radiator draincock and install cylinder block drain plugs.
- When refilling the engine cooling system, use equal parts of water and Ford Premium Engine Coolant E2FZ-19549-AA, (in Oregon FSFZ-19549-CC, in Canada, Motorcraft CXC-8-B), recycled coolant or equivalent meeting Ford specification ESE-M97B44-A. Freeze protection may also be checked by using either a Rotunda Battery and Antifreeze Tester 014-R1060 or equivalent or a hydrometer. A 50/50 mix of coolant concentrate and water will provide approximately -37°C (-35°F) protection and provide the necessary anti-corrosion protection.
- Fill radiator until engine coolant level in the radiator reaches the radiator filler neck seat.
Refill the radiator to approximately 0 to 5 cm (0 to 2 inches) below the filler neck seat.

4. Operate engine until water thermostat opens and the radiator upper 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.

5. Stop the engine and add a 50/50 mixture of Ford Premium Engine Coolant E2FZ- 19549-AA, (in Oregon F5FZ-19549-CC, in Canada, Motorcraft CXC-8-B) or equivalent meeting Ford specification ESE-M97B44-A and water up to the filler neck seat.
6. Install radiator cap.





7. Add a 50/50 mixture of Ford Premium Engine Coolant E2FZ-19549-AA, (in Oregon F5FZ-19549-CC, in Canada, Motorcraft CXC-8-B) or equivalent meeting Ford specification ESE-M97B44-A and water to the FULL HOT mark on the radiator coolant recovery reservoir to provide adequate cooling system fill. Install radiator cap (if equipped).





8. Bleed cooling system as follows:
- Select maximum heater temperature and blower motor speed settings. Position control to discharge air at A/C vents in instrument panel.
- Start engine and allow to idle. While engine is idling, feel for hot air at A/C vents.

CAUTION: If air discharge remains cool and engine coolant temperature gauge does not move, engine coolant level is low in engine and must be filled. Stop engine, allow to cool and fill cooling system.

Start engine and allow to idle until normal operating temperature is reached. Hot air should discharge from A/C vents. The engine coolant temperature gauge should maintain a stabilized reading in the middle of the NORMAL range and the upper radiator hose should feel hot to the touch.
- Shut engine off and allow to cool.
- Check engine for coolant leaks.
- Check engine coolant level in degas bottle and fill as necessary.
