How to Select Coolant

This section covers selection of
the required coolant for MBE 900
engines.
Definitions
To help ensure complete
understanding of the information, the
definitions of the following terms are
provided:
Antifreeze — Ethylene glycol
or propylene glycol containing a
corrosion inhibitor package and which
meets an appropriate heavy-duty
specification (i.e., TMC RP-329
"Type A" for ethylene glycol or
TMC RP-330 "Type A" for propylene
glycol).
Coolant — The fluid mixture
circulating in the engine cooling
system, typically a mixture of 50%
water and 50% antifreeze.
Drop–Out — Precipitated sludge or
deposit formation on cooling system
components.
Fully Formulated Antifreeze —
Contains all the necessary inhibitors
to protect a diesel engine, and does
not, therefore, require a pre-charge of
SCA before its first use.
All information subject to change without notice. (Rev. 04/08)

Initial–Fill Coolant — The coolant
that is used in a new or rebuilt engine,
or any time the cooling system is
emptied and then refilled with coolant.
OAT — Organic Acid Technology.
An inhibitor system based on
organic acid inhibitors, instead of
traditional North American inhibitor
formulations.
SCA — Supplemental Coolant
Additive. SCAs are used in a
preventive maintenance program to
prevent corrosion, cavitation, and the
formation of deposits.

Approved Coolants

The approved and preferred
coolants for MBE 900 engines
are listed in Table 12.
Once installed, these coolants
should be maintained according
to the procedures discussed under
Maintenance in this section.
