Conventional coolant is recommended as it commonly available and has a
greater thermal heat transfer capability. Its limitation is its lower boiling
point.
Waterless cool-
ant
Waterless coolant is recommended if the design of the aircraft can not
maintain the coolant temperature limit.
Mixing ratio
Boiling point Conventional coolant:
Conventional coolant with a rate of 50 % water cannot boil at a tempera-
ture below 120 °C (248 °F) at a pressure of 1.2 bar (18 psi). The max.

Permanent monitoring of coolant temperature and cylinder head tempera-
ture is necesssary.
