3.1.2 PRE-OPERATION INSPECTION
Inspections described in this section should be conducted just once before the first engine start-up of the
day.
[1] INSPECTION/REFILLING OF ENGINE COOLANT
• Do not open the radiator cap in a normal case. Inspect the coolant in the sub-tank when the
engine is cool.
• Coolant temperature is high immediately after stopping the engine and pressure is
accumulated in the radiator. Opening the cap in this state may cause burns. Turn the cap
slowly to release pressure after the temperature lowers and carefully remove it.
1. Open the sand cover and check that the cooling water is
within the sub-tank (1) (right figure) FULL - LOW range. If
there is not enough, supply water to the FULL level from
the water supply port of the sub-tank (1).
2. Fully tighten the cap after replenishing the water.
3. If the sub-tank is empty, check that the coolant is not
leaking and inspect the coolant level in the radiator. If
coolant runs short, supply coolant to the radiator and then
to the sub-tank.
