CHECK COOLANT LEVEL, ADD COOLANT
WARNING
Do not open the radiator cap (1) unless necessary. When checking the
coolant level, check the reservoir tank (2) when the engine is cold.
Immediately after the engine is stopped, the coolant is still very hot and
the radiator is under high internal pressure. If cap (1) is removed in this
condition, there is a hazard of burns. Always wait for the temperature to
go down, turn cap (1) slowly to release the pressure, then remove the
cap with care.
1. Open the engine side cover on the left side of machine and
check that the coolant level (4) in reservoir tank (2) is between
FULL and LOW marks. If it is insufficient, add coolant
according to the following procedure. After starting the engine,
if radiator coolant level caution lamp flashes, add coolant
according to the following procedure.
REMARK
The coolant may overflow from the reservoir tank drain hose.
This is no problem. It occurs because too much coolant has been
added.
2. If the reservoir tank is empty, leakage of coolant is suspected.
After checking, repair any abnormality immediately. If no
abnormality is found, check the level of the coolant in the
radiator. If it is low, add coolant of the same density according
to the coolant density table in "CLEAN INSIDE OF COOLING
SYSTEM (PAGE 4-22)".
3. Remove cap (1) and add coolant through water filler port.
Check that the coolant is above the top of strainer (3). At the
same time, remove the cap (5) and refill reservoir tank (2) with
coolant until it reaches to FULL level.
4. Refill with coolant while engine is stopped. When the coolant
flows out from the water filler port, stop refilling it once and run
the engine at Low idle (MIN) for approximately 5 minutes.
Check the coolant level again. If it is insufficient, be sure to fill
the tank with coolant.
If the water level low error is not eliminated even after refilling
of coolant, ask your Komatsu distributor for repairs.
5. After adding water, tighten caps (1) and (5) securely.
