DRIVE AXLE WHEEL BEARING OIL LEVEL

Drive axle wheel bearings are lubricated by the
differential oil. Maintain differential oil at correct
level to ensure adequate lubrication of drive axle
wheel bearings at all times.

FRONT AND TAG AXLE WHEEL HUBS

The unitized hub bearings used on the NDS
range of axles, are non-serviceable items.
Bearings are pre-adjusted, lubricated and have
seals fitted as part of the manufacturing process.
The bearings are greased for life and there is no
need or facility for re-lubrication.

COOLANT FLUID LEVEL

Check the coolant level when the engine is cold
(room or ambient temperature).

Fill the tank as required with the same 50/50
water-antifreeze mixture already in the cooling
system. Do not mix two different types of
coolant. Refer to the Maintenance Manual for
proper coolant type specifications or see the
label affixed near the coolant surge tank on the
vehicle.
On Volvo D13 engine, use only Extended Life
Coolant (ELC). Do not add supplemental
coolant additives (SCA) to extended life
coolant. Do not use a coolant filter containing
Supplemental Coolant Additives (SCA).
When the coolant level reaches the coolant
surge tank level sensor, the STOP telltale light
illuminates, a beeping tone rings and "
COOLANT LEVEL CRITICALLY LOW
appears in the DID. Stop the vehicle in a safe
location and add coolant to the cooling system
surge tank as soon as possible.
