Cooling System Leak Testing

Warning

Under pressure, the temperature of the solution in the radiator can be considerably higher, without boiling. Removing the radiator cap while the engine is hot (pressure is high), will cause the solution to boil instantaneously, with explosive force. The solution will spew out over the engine, fenders, and the person removing the cap. Serious bodily injury may result. Flammable antifreeze, such as alcohol, is not recommended for use at any time. Flammable antifreeze could cause a serious fire.

Note: The charge air cooling system is leak tested visually with the charge air cooler pump ON.

1. Connect the 7000081 - Tech 2 Kit to the vehicle.
2. Command the charge air cooling pump ON using the 7000081 - Tech 2 Kit.
3. Run the pump for at least 2 minutes. Observe the charge air cooling system hoses and components for any sign of coolant leakage.
4. Repair any leaks as required. Refer to the appropriate repair procedure.
