Refer to Master Parts List for service part numbers and applications.
Service refill recommendations are 50/50 mixture of water and permanent coolant/antifreeze such as Ford Premium Cooling System Fluid E2FZ-19549-AA or B or equivalent meeting specification ESE-M97B44-A plus 1.41 (1.5 qts) of Heavy Duty Cooling System Additive FW-15 or equivalent meeting Ford specification ESN-M99B169-A.
Minimum acceptable coolant/water concentration is 45 percent antifreeze to 55 percent water. Maximum acceptable is 60 percent coolant to 40 percent water. Use only a hand-held refractometer such as Rotunda Battery/Antifreeze Tester 021-00046 or equivalent to check concentration.
In an emergency, ordinary tap water with a low alkali content may be used provided the system is drained and flushed and filled with the specified coolant/water mixture as soon as possible. Use only if that temperature is above 0°C (32°F).
NOTE: 7.3L diesel engines require a supplemental coolant additive to provide corrosion protection consistent with diesel engine characteristics. Without the supplemental additive Motorcraft FW-15 or equivalent, cylinder wall erosion may occur.
The recommended quantity of coolant additive when refilling the entire cooling system is 1.4 litres (1-1/2 quarts). Refreshing the coolant mixture with an additional 237 ml (8 oz.) of Motorcraft FW-15, or equivalent, each 15,000 miles (24,000 km) or 12 months is recommended.
