57.6.6 Engine Cooling System
The engine cooling system is designed to
maintain the engine operating temperature
within the specified operating range.
NOTE
Anti-freeze is essential in any climate. It
broadens the operating temperature range
by lowering the coolant freezing point and
by raising its boiling point. Anti-freeze
also contains rust inhibitors and other
additives to prolong engine life.
IMPORTANT
If anti-freeze 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 maintenance 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 lowest
position.
57.6.6.1 Coolant Level and Concentration
a. Check daily the coolant level in the coolant
recovery tank (A). Tank should be at least half
full.

Use Ethylene Glycol with SCA and equal parts
of high quality, soft, de-ionized, or distilled water

engine to temperatures of -30
°F (-34°C).

Do not add coolant to radiator except
