8.11 Maintenance of Coolant System
z
Severe burn may be caused if the cover of the oil tank and the radiator are opened after welding,
so pour water or oil on the cover of the oil tank immediately after finishing welding. The
temperature and pressure of hydraulic oil, fuel and water in the engine, the oil and water in the
radiator may be still very high after just finishing the work. Wait for the temperature falling down
and follow the procedures to do the operations above.
z
To avoid hot water ejecting from the radiator, stop
the engine, let the hot water cool, and open the cover
slowly to release the pressure. Never touch the
radiator. Check the air temperature in front of the
radiator to gauge the temperature.
