Coolant: Service and Repair

DESCRIPTION
A 50/50 mixture of Premium Cooling System Fluid E2FZ-19549-AA or B, in Oregon F5FZ-19549-CC, in Canada, Motorcraft CXC-8-B recycled coolant, or equivalent meeting Ford specification ESE-M97B44-A and water should be added to the degas bottle to the specified levels.

PROCEDURES
1. With cold engine, remove pressure relief cap.
2. With 50/50 mixture of coolant and water, fill coolant and replace pressure relief cap. Observe the level of fluid in the degas bottle. Adjust 50/50 mixture of coolant and water to the FULL COLD mark on the degas bottle.
3. Start the engine and run until the water thermostat (8575) opens.
4. Shut off the engine and allow it to cool down. This permits engine coolant to be drawn into the radiator (8005).
5. Observe the engine coolant level in the degas bottle. The minimum level should be as specified in Step 2 If not, adjust engine coolant level by adding a 50/50 mixture of coolant and water.
6. Check engine coolant level in radiator when engine has cooled. Radiator should be full. Add a 50/50 mixture of coolant and water if necessary. Repeat Steps 3,4 and 5.
7. Check for leakage at:
a. All hoses and hose connections.
b. Radiator seams, radiator core and radiator draincock (8115).
c. All cylinder block core plugs and drain plugs.
d. Edges of all cooling system gaskets.
e. Transmission oil cooler fittings (if equipped).
f. Vehicle heating system components.
g. Water pump (8501).
8. Examine oil level dipstick (6750) for evidence of engine coolant in engine oil.
9. Check radiator for evidence of transmission fluid in engine coolant (leakage). Install cooling system analyzer to assist in testing the cooling system. Follow the manufacturer's recommended connections and testing procedures.

NOTE: If no engine coolant is observed in the degas bottle or when an engine coolant level change does not occur, check the system as follows:

10. With the engine cold, remove the pressure relief cap, and inspect the filler neck sealing gasket for foreign material between the gasket and diaphragm. Refer to Radiator Cap Cleaning and Inspection. Rinse pressure relief cap in clean water. The pressure relief cap used on this system is unique; replace only with the proper pressure relief cap.
11. Remove the radiator overflow hose at the radiator connection. Remove degas bottle from front fender apron (16055) and flush with clean water.
12. Inspect the radiator overflow hose for obstructions, cracks or cuts. Replace if necessary.
13. Install degas bottle and connect radiator overflow hose at the radiator connection.
14. Replenish the engine coolant in the radiator and add a 50/50 mixture of coolant and water to degas bottle as required.
15. Install the pressure relief cap.
