7. Fill engine coolant into expansion tank assembly up to standard scale to discharge air from 
cooling pipe. 

8. Start the engine until the thermostat opens. When two water inlet/outlet pipes of the radiator are 
hot, it means that the thermostat has been opened. 

9. Shut down the engine. Confirm that the engine coolant drainage valve is not leaking. (Repeat 
the above steps until the discharged coolant is free of bubble.) 

10. Fill the engine coolant so that the engine Coolant Recovery Reservoir coolant level reaches the 
highest scale (F location).
