System Overview

WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty, 2013 Ford F-450 Super Duty, 2013 Ford F-350 Super Duty, and 2013 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Always fill the cooling system with the manufacturer's specified coolant. Chemically flush the cooling system if a non-specified coolant has been used. Refer to COOLING SYSTEM FLUSHING - WITHOUT OIL CONTAMINATION . Failure to follow these instructions may damage the engine or cooling system.

Engine coolant provides boil protection, corrosion protection, freeze protection and cooling efficiency to the engine and cooling components. In order to obtain these protections, maintain the engine coolant at the correct concentration and fluid level in the degas bottle.

When adding engine coolant, use a 48/52 to 50/50 (freeze protection -34°C to -37°C [-30°F to -34°F]) mixture of engine coolant and distilled water.

To maintain the integrity of the coolant and the cooling system:

NOTE: With the engine cold, fill vehicles to within the cold fill range shown on the degas bottle. This fill level allows for coolant expansion. Overfilling the degas bottle may result in damage to the pressure cap, which can cause the engine to overheat.

Add Motorcraft® Orange Antifreeze/Coolant. Do not mix coolant types. Mixing coolants may degrade the coolant's corrosion protection.
Do not add alcohol, methanol, brine or any engine coolants mixed with alcohol or methanol antifreeze. These can cause engine damage from overheating or freezing.
Do not mix with recycled coolant. Use of such coolants may harm the engine and cooling system components. Do not mix coolant types.
