DIFFERENTIAL

Multigrade gear oil meeting MIL- PRF- 2105E:
85W-140 is recommended for use in the Meritor
drive axle. This lubricant performs well over a
broad temperature range, providing good gear
and bearing protection in a variety of climates. If
temperature drops below 10°F (-12°C), 80W-90
should be used, and below -15°F (-26°C), 75W-
90 should be used. In extreme conditions or for
better performance, full synthetic gear oil should
be used.
For vehicles equipped with the ZF A- 132 drive
axle, use ZF Ecofluid 80W-90 (ZF lubricant class
12M) or refer to ZF List of lubricants TE-ML 12 for
other approved lubricants.

POWER STEERING RESERVOIR

Use Automatic Transmission Fluid (ATF) Dexron-
III (F, G or H) or Dexron-IV for this system.

PRE-HEATING SYSTEM

Depending on options chosen, a coolant heater
may be installed on the coolant circuit. The
heater can be used as a pre- heater or as an
auxiliary heat source.
The heater is controlled
programmable timer. Refer to
page 16 in Other Features, Section 5 for
information on how to use the timer.
