General Description
Coolant Description
AENAR90A1601002
The coolant recovery system is a standard system,
which allows part of coolant to flow from the radiator into
the coolant reservoir when it is expanded by heat. When
the cooling system cools down, the coolant in the
coolant reservoir is drawn back into the radiator.
The cooling system has been filled with a quality coolant
that is a 70/30 mixture of water and ethylene glycol
antifreeze.
This 70/30 mixture coolant solution provides freezing
protection to a temperature as low as –15 °C (5 °F).
• Freeze protection down to –15 °C (5 °F) is also
important to ensure protection against corrosion and
loss of coolant from boiling. This level of protection
should be maintained 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 temperatures lower than
–15 °C (5 °F).
NOTE
• Ethanol 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.
• Coolant must be mixed with demineralized
water or distilled water.
