RADIATOR FILLING PROCEDURE
The cooling system is pressurized due to thermal
expansion of coolant. DO NOT remove the radia-
tor cap while the engine and coolant are hot.
Severe burns may result.
1. With the engine and coolant at ambient temper-
ature, remove the 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 the radiator with the proper coolant mixture
(as specified by the engine manufacturer) until
coolant is visible in the sight gauge.
3. Install the radiator cap.
4. Operate the engine for five minutes. Check the
coolant level.
5. If coolant is not visible in the sight gauge,
repeat Steps 1 through 4. Any excess coolant
will be discharged through vent hose after the
engine reaches normal operating temperature.
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 the reserve oil system. Never add oil to the
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 the 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, Figure 2-1) to turn the sys-
tem 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 FULL light (4) will illuminate.
5. Close the oil supply valve in the fill hose.
6. Press and hold start switch (3) for a couple of
seconds.
7. Disconnect the new oil supply hose.
8. Push switch (2) in to turn system power OFF.
