Flushing

Important: Do not use a chemical flush.


Store used coolant in the proper manner, such as in a used engine coolant holding tank. Do not pour used coolant down a drain. Ethylene glycol antifreeze is a very toxic chemical. Do not dispose of coolant into the sewer system or ground water. This is illegal and ecologically unsound.


Various methods and equipment can be used to flush the charge air cooling system. If special equipment is used, such as a back flusher, follow the manufacturer's instruction.



When the charge air cooling system becomes contaminated, the system should be flushed thoroughly to remove the contaminants before any components are damaged.

1. Drain the charge air cooling system. Refer to Charge Air Cooling System Draining and Filling (Static Fill) (Charge Air Cooling System Draining and Filling (Static Fill)) .
2. Follow the FILL procedure using only clean, drinkable water. Refer to Charge Air Cooling System Draining and Filling (Static Fill) (Charge Air Cooling System Draining and Filling (Static Fill)) .
3. Cycle the charge air coolant pump ON with the TECH 2 for approximately 5 minutes.
4. Cycle the charge air coolant pump OFF.
5. Drain the charge air cooling system. Refer to Charge Air Cooling System Draining and Filling (Static Fill) (Charge Air Cooling System Draining and Filling (Static Fill)) .
6. Repeat the procedure if necessary, until the fluid is nearly colorless.
7. Fill the charge air cooling system. Refer to Charge Air Cooling System Draining and Filling (Static Fill) (Charge Air Cooling System Draining and Filling (Static Fill)) .
