Coolant: Description and Operation
COOLANT
The coolant recovery system is standard. The coolant in the radiator expands with heat, and the overflow is collected in the reservoir. When the system
cools down, the coolant is drawn back into the radiator.
The cooling system has been filled at the factory with a quality cool and that is a 50/50 mixture of water and ethylene glycol antifreeze.
This 50/50 mixture coolant solution provides freezing protection to -36°C (-33°F).
^
Maintain cooling system freeze protection at -36°C (-33°F) to ensure protection against corrosion and loss of coolant from boiling.
This should be done even if freezing temperatures are not expected.
^
Add ethylene glycol base coolant when coolant has to be added because of coolant loss or to provide added protection against freezing at
temperature lower than -36°C (-33°F).
NOTE:
^
Alcohol or methanol base coolant or plain water alone should not be used in cooling system at any time as damage to cooling system could
occur.
