Cooling liquid

The system of regeneration of cooling liquid is standard. Cooling liquid in a radiator extends in process of heating, and surplus gathers in the tank. When the system is cooled, cooling liquid flows back in a radiator. The system of cooling liquid was filled at the plant with the qualitative cooling liquid representing mix 50/50 of water and antifreeze ethylene glycol.

This mix 50/50 of the cooling solution gives protection against freezing to -36 °C (-33 °F).

Support protection against freezing of the cooling system at -36 °C (-33 °F) to provide protection against corrosion and loss of cooling liquid because of boiling. It should be done even then when low temperature and is not expected. Add cooling liquid on a basis glycol ethylene when cooling liquid needs to be added because of loss of cooling liquid or to provide additional protection against frost penetration at a temperature below -36 °C (-33 °F).

Scheme of selection of composition of antifreeze

Freezing temperature		°C	- 36
Freezing temperature		°F	- 33
Concentration of antifreeze / anticorrosive cooling liquid		%	50
Mix ratio to the cooling water	G16 engine	Itr.	2.8/2.8
		US pt	5.8/5.8
		Imp. Pt.	4.9/4.9
	J20 engine	Itr.	3.3/3.3
		US pt	6.9/6.9
		Imp. Pt.	5.7/5.7

The cooling ability

		Engine, radiator and heater	Tank	Total
G16 engine	ltr. (US/lmp.pt.)	4.6 (9.7/8.1)	0.9 (1.9/1.6)	5.5 (11.6/9.7)
J20 engine	ltr. (US/lmp.pt.)	5.6 (11.8/9.1)	0.9 (1.9/1.6)	6.5 (13.7/11.4)

Cooling liquids on the basis of alcohol or methanol or only idle time water never have to be used in the cooling system as it can lead to damage of the cooling system.

Cooling liquid has to be mixed with the distilled water or demineralized water.
