Cooling System Pressure Test
2009 Ford RV Cutaway 6.8 SSECTION Cooling System Pressure Test
WARNING:
Always allow the engine to cool before opening the cooling system. Do not unscrew the coolant pressure relief cap when the engine is operating or the cooling system is hot. The cooling system is under pressure; steam and hot liquid can come out forcefully when the cap is loosened slightly. Failure to follow these instructions may result in serious personal injury.
- Turn the engine OFF.
- Check the engine coolant level. Adjust the coolant level as necessary.
- Attach the Radiator/Heater Core Pressure Tester from the Pressure Test Kit to the degas bottle nipple and overflow hose. Install a pressure test pump to the quick-connect fitting of the test adapter.
NOTE:
Do not pressurize the cooling system beyond the maximum pressure listed in the specifications table or cooling system components can be damaged.
