A make-up dosage of 1 pint for every 20 gallons of system capacity should be added every 10,000 to 12,000 miles for line haul trucks, or every 250 operating hours for low mileage trucks, stationary, off-road or marine units. NOTE: Engine cooling system should be drained, flushed and chemically cleaned before starting initial treatment.
