7.9.7 ENGINE COOLING SYSTEM
The engine cooling system is designed to maintain
the engine operating temperature within the
specified operating range.
NOTE
Antifreeze is essential in any climate. It
broadens the operating temperature range
by lowering the coolant freezing point and
by raising its boiling point. Antifreeze also
contains rust inhibitors and other additives
to prolong engine life.
IMPORTANT
If antifreeze strength is not adequate, do not
drain cooling system to protect against
freezing. System may not drain completely,
and damage from freezing could still result.
To service the cooling system, perform the
following:
DANGER
Stop engine and remove key from ignition
before leaving Operator’s seat for any reason.
A child or even a pet could engage an idling
machine.
a. Stop engine and remove key.
b. Move the left cab-forward platform to the open
position for access to the coolant tank and
radiator. Ensure the platform latch is engaged in
open position.
c. Raise engine compartment hood to highest
position.
7.9.7.1 Coolant Level and Concentration
a. Check daily the coolant level in the coolant
recovery tank (A). Tank should be at least half
full.

Ethylene Glycol with SCA equal parts with high
quality, soft, de-ionized or distilled water as
recommended by the supplier to protect the
engine to temperatures of -30
°F (-34°C).
