Shop with Blessed Performance for the Motorcraft Diesel Cooling System Additive for your 1994-2010 Ford 7.3L/6.0L/6.4L Powerstroke diesel. 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 Powerstroke Diesel engine. Many other coolants do not have the necessary nitrite and silicate levels. Motorcraft Supplemental Coolant Additive recharges depleted silicates and nitrites in the cooling system.
