Coolant & Additive

Find the Coolant & Additives you need when servicing the cooling system in your 4BT 3.9L Diesel. In addition to full synthetic antifreezes, you can also get additional additives that provide you with a coolant service life of 150,000 to 750,000 miles. These additives will minimize surface tension for more efficient cooling, prevent corrosion, offer faster warm-ups, and reduce engine temperatures.
