General maintenance information Whenever coolant has been added, the coolant level in the coolant reservoir should be checked the next few times you drive the vehicle. If necessary, add enough 50/50 concentration of engine coolant and distilled water to bring the liquid level to the proper level. If you have to add more than 1.0 liter (1.0 quart) of engine coolant per month, have your dealer check the engine cooling system. Your cooling system may have a leak. Operating an engine with a low level of coolant can result in engine overheating and possible engine damage. Replacing coolant A coolant mixture of 50% coolant concentrate and 50% water is recommended to maintain best overall performance. To avoid damaging the engine and radiator, the coolant concentrate should not exceed 60%. When refilling the coolant system either as part of the regular maintenance (refer to the scheduled maintenance guide), or due to service performed, adhere to the following instructions: 1. Drain and flush the cooling system to remove dirt deposits, oil, rust particles. Note: When filling the system with Motorcraft Premium Engine Coolant (green-colored) or equivalent meeting Ford specification ESE-M97B44-A, a supplemental coolant additive is required. Refer to Adding Coolant section to determine the coolant type in your vehicle. Add 1.89L (4 pints) of Motorcraft Heavy Duty Cooling System Additive FW-16 or equivalent meeting Ford specification ESN-M99B169-A, directly to the cooling system. An additional 237-295 ml (8-10 oz.) of supplemental coolant additive FW-16 should be added at 24,000 km (15,000 mile) intervals to maintain proper concentration. Do not use this additive with yellow-colored coolant meeting Ford specification WSS-M97B51-A1. 2. Fill the coolant reservoir with the specified coolant/water mixture until the level stabilizes at the top hose fitting. Replace and tighten cap. Fill the coolant bottle to the cold fill mark. 3. Reinstall the coolant bottle cap. 4. Start and idle engine until the radiator upper hose is warm (approximately 10-15 minutes). If the hose does not get warm then repeat at a higher engine speed. 5. Immediately shut off engine. Allow engine to cool before removing coolant bottle cap. Cautiously remove coolant bottle cap and add coolant to Cold Fill mark. 40

Replacing coolant
A coolant mixture of 50% coolant concentrate and 50% water is
recommended to maintain best overall performance. To avoid damaging
the engine and radiator, the coolant concentrate should not exceed 60%.
When refilling the coolant system either as part of the regular
maintenance (refer to the scheduled maintenance guide), or due to
service performed, adhere to the following instructions:
1. Drain and flush the cooling system to remove dirt deposits, oil, rust
particles.
Note:
When filling the system with Motorcraft Premium Engine Coolant
(green-colored) or equivalent meeting Ford specification
ESE-M97B44–A, a supplemental coolant additive is required. Refer to
Adding Coolant
section to determine the coolant type in your vehicle.
Add 1.89L (4 pints) of Motorcraft Heavy Duty Cooling System Additive
FW-16 or equivalent meeting Ford specification ESN-M99B169–A,
directly to the cooling system. An additional 237–295 ml (8–10 oz.) of
supplemental coolant additive FW-16 should be added at 24,000 km
(15,000 mile) intervals to maintain proper concentration.
Do not use
this additive with yellow-colored coolant meeting Ford
specification WSS-M97B51–A1.
2. Fill the coolant reservoir with the specified coolant/water mixture until
the level stabilizes at the top hose fitting. Replace and tighten cap. Fill
the coolant bottle to the cold fill mark.
3. Reinstall the coolant bottle cap.
4. Start and idle engine until the radiator upper hose is warm
(approximately 10–15 minutes). If the hose does not get warm then
repeat at a higher engine speed.
5. Immediately shut off engine. Allow engine to cool before removing
