Radiator Filling Procedure - Komatsu 830E Shop Manual

COOLANT LEVEL CHECK
Inspect the coolant sight gauge. If coolant cannot be
seen in the sight gauge, it is necessary to add cool-
ant to the system before truck operation. Refer to the
procedure below for the proper filling procedure.

RADIATOR FILLING PROCEDURE

Cooling System is pressurized due to thermal
expansion of coolant. DO NOT remove radiator
cap while engine and coolant are hot. Severe
burns may result.
1. With engine and coolant at ambient tempera-
ture, remove radiator cap.
Note: If coolant is added using the Wiggins quick fill
system, the radiator cap MUST be removed prior to
adding coolant.
2. Fill radiator with proper coolant mixture (as
specified by the engine manufacturer) until
coolant is visible in the sight gauge.
3. Install radiator cap.
4. Run engine for 5 minutes, check coolant level.
5. If coolant is not visible in the sight gauge, repeat
steps 1 through 4. Any excess coolant will be
discharged through the vent hose after the
engine reaches normal operating temperature.
NOTE: Engine coolant must always be visible in
the sight gauge before truck operation.

Lubrication and Service
Reserve Engine Oil System (Optional)
The reserve oil tank for the engine is designed to add
more oil capacity to the engine to reduce the frequent
servicing of the engine oil. The engine oil level must
still be checked every shift using the dipstick. If
engine oil level is not correct, check for proper opera-
tion of reserve oil system. Never add oil to engine
unless it has been drained.
If the engine oil has been drained from the oil pan,
the new oil must be added to the engine oil pan
before starting. DO NOT use the oil in the reserve
tank to fill an empty engine with oil. After an oil
change, both engine and reserve tank must be full of
oil before starting the engine.
Reserve Oil Tank Filling Procedure (Remote fill)
1. Connect the pressure supply hose from the new
oil supply to the quick coupler on the truck.
Open valve on supply hose to apply pressure.
2. Pull out on switch (2) to turn the system ON.
3. Push start switch (3). The "Valve Open" light (5)
should illuminate and the filling process will
begin.
4. When tank is full, the "Valve Open" light will turn
OFF and the FULL light (4) will illuminate.
5. Close the oil supply valve in the fill hose.
6. Press and hold start switch (3) for several sec-
onds.
7. Disconnect the new oil supply hose.
Push switch (2) in to turn system power OFF
