OPERATION
Checks Before Starting
Always check the items in this section before starting the engine each day.
Check Coolant Level, Add Coolant
Do not open the radiator cap unless necessary. Wait for the engine to cool down before checking the coolant in the sub-tank.
Immediately after the engine is stopped, the coolant is at a high temperature and the radiator is under high internal pressure.
If the cap is removed to check the coolant level in this condition, there is a hazard of burns. Wait for the temperature to go
down, then turn the cap slowly to release the pressure before removing it.
1. Open the engine rear cover and cooling cover. For details, see "COOLING COVER (PAGE 3-29)".
2. Check that the coolant level is between the FULL and LOW range on sub-tank (1). If the coolant level is low,
add coolant through the water filler port of sub-tank (1) to the FULL line.
