Shut the truck off and let engine cool. • • Drain the water out of the cooling system again by opening the radiator drain petcock and removing the engine block plugs. • • Remove a heater core hose to drain the heater core. • • If water drained from the cooling system has no debris and is clear go to the next step of adding coolant. If the water is still contaminated then reinstall heater hose, engine block drain plugs, and tighten the radiator petcock drain. Repeat the last procedure one more time allowing the cooling system to cool before opening the system to drain the water. Why is it necessary to remove the engine block drain plugs during the flush and fill process? If the block drain plugs are not removed, 20% - 30% of the contaminated coolant or flush water remains in the engine block. In a 12 gallon system that equals up to 3 to 4 gallons of contaminated coolant or flush water left in the cooling system. This will contaminate any new HD Antifreeze/ Coolant added the cooling system. Now it’s time to add the coolant. Make sure all engine block plugs and hoses are reinstalled, and the radiator drain plug is tightened. Check the OEM manual for recommended procedures for filling the cooling system. HD trucks may have different procedures depending on year, make and model. Pour in your preferred technology of Prestone Command® HD Antifreeze/Coolant. If using a concentrated antifreeze/coolant pour in half the recommended volume for the cooling system capacity. Top off the rest of the cooling system with distilled or deionized water. DO NOT USE well water or tap water unless you have tested the water with Prestone® Water Analysis Test Strips. Using hard or contaminated water is the quickest way to destabilize your system. If using a 50/50 pre-mixed coolant, pour in the recommend amount of coolant. Install the pressure cap and run the truck to operating temperature and monitor the temperature gauge for any overheating. Let the system cool and check the cooling system level. Using the Prestone® Refractometer, check the coolant freeze point, it should be -340 Fahrenheit. If the cooling system is low and the freeze point has not reached -340 Fahrenheit add enough concentrate to the system to bring the temperature to -340 Fahrenheit. If the system is still low at this time top off the rest of the cooling system with 50/50 pre-mixed to maintain the proper temperature range. If the cooling system is low and the temperature range has a lower freeze point than -340 Fahrenheit add water to the system until it tests at -340 Fahrenheit. Remember to run the engine to operating temperature after adding coolant or water. This mixes the newly added fluid in order to properly determine the correct temperature test reading. Please remember to properly dispose any used coolant and flush water according to Federal, State, and Local laws. Prestone ® offers three different heavy duty antifreeze/coolant technologies for your HD truck.
