After draining, flush system (including heater core) thoroughly and reconnect hose. Slowly add sufficient treatment premixed at 30% - 50% with distilled water to fill the cooling system. Refer to the vehicle owners manual for required dosage and dilution rate. To avoid possible incompatibility problems, do not mix with other coolant formulations.
