Protect Your Power Stroke® Diesel Engine with the right Motorcraft Coolant

Using the proper engine coolant is important to the operation of your Power Stroke Diesel engine. Ford recommends owners use specifically formulated coolants in their engines. Keep your Power Stroke Diesel running great by following recommended scheduled maintenance and using quality original equipment parts* offered at your local Ford dealer.

Why is using the proper Motorcraft coolant so important? Ensures proper coolant flow inside your cooling system Protects internal components from corrosion

Using the wrong type of coolant and colors or even mixing different coolants together can lead to major issues:

Sludge forming in the cooling passages Internal component corrosion and failure Overheating of engine and components Cylinder wall cavitation Loss of engine performance

Different engines require different chemical concentrations in their coolant. Proper levels of nitrite and silicate are what give Motorcraft coolant its ability to protect your Power Stroke Diesel engine. Many other coolants do not have the necessary nitrite and silicate levels. Silicates and nitrites protect against:

Corrosion and clogging of aluminum (oil coolers & EGR coolers)

Cavitation on cylinder walls

Motorcraft Supplemental Coolant Additives recharge depleted silicates and nitrites in the cooling system and should only be used when necessary.

* See reverse side for coolant product and maintenance schedule information.

The engine coolant system nitrite level should be checked at the mileage or equivalent hour intervals specified by the maintenance schedule.

Add Diesel Supplemental Coolant Additive as necessary

When should I flush my Power Stroke Diesel engine’s cooling system?A coolant flush should be performed when contaminants are found inside the engine’s cooling system. Consult the Ford Workshop Manual to determine if a coolant flush is appropriate (see your local Ford dealer for more details). If a flush is recommended, use Motorcraft VC-9 Diesel Cooling System Iron Cleaner. Motorcraft VC-9 is designed to remove rust and other cooling system contaminants that restrict flow inside the cooling system. It is important to remember that a flush is not appropriate for every situation and should only be used when specified by the Ford Workshop Manual.
