Coolant Level Check

DESCRIPTION
Check engine coolant level in the radiator coolant recovery reservoir (8A080) at least once a month.
- With a cold engine, the engine coolant level must be maintained at or above the MIN mark.
- At normal engine operating temperature, the engine coolant level should be at the MAX mark.
If engine coolant level in the radiator coolant recovery reservoir is less than the above indicated levels, a 50/50 mixture of Ford Premium Cooling System Fluid E2FZ-19549-AA or-B (In Canada Motorcraft CXC-8-B) or equivalent meeting Ford specification ESE-M97B44-A and water should be added to the radiator coolant recovery reservoir to the specified levels.

NO COOLANT IN RESERVOIR
In the event no coolant is observed in the radiator coolant recovery reservoir or when an engine coolant level change does not occur, check the system as follows:

NOTE: The pressure relief cap used on this system is unique; replace only with proper pressure relief cap.

1. With engine cold, remove pressure relief cap and inspect filler neck sealing gasket for foreign material between the gasket and cap diaphragm. Rinse pressure relief cap in clean water.
2. Remove radiator coolant recovery reservoir and flush with clean water.
3. Inspect radiator overflow hose (8075) for obstruction, cracks or cuts. Replace if necessary.
4. Install radiator overflow hose and radiator coolant recovery reservoir.
5. Replenish coolant in cooling system as required.
6. Install pressure relief cap.

LOW COOLANT IN RESERVOIR
A low engine coolant level in the radiator (8005) can cause poor heater and defroster performance. If this condition exists, perform the following:
1. With cold engine, remove pressure relief cap.
2. With 50/50 mixture of Ford Premium Cooling System Fluid E2FZ-19549-AA or-B (in Canada, Motorcraft CXC-8-B) or equivalent meeting Ford specification ESE-M97B44-A and water, fill radiator coolant recovery reservoir to indicated level and replace pressure relief cap.
3. Start the engine and run until the water thermostat (8575) opens. Observe the engine coolant level in the radiator coolant recovery reservoir. The minimum level should be at MAX mark. If not, add specified engine coolant.
4. Check for leakage at:
- All hoses and hose connections.
- Radiator seams, radiator core and radiator draincock (8115).
- All cylinder block core plugs and drain plugs.
- Edges of all cooling system gaskets.
- Transmission oil cooler fittings.
- Vehicle heating system components.
- Water pump (8501).
- Examine oil level dipstick (6750) for evidence of engine coolant in engine oil.
5. On automatic transaxle equipped vehicles, check radiator for evidence of transmission fluid in coolant (leakage at transmission oil cooler).
6. Install a suitable cooling system analyzer to assist in testing the engine cooling system. Follow the tool manufacturer's recommended connections and testing procedures.
