Type 44 - Checking and correcting coolant antifreeze concentration and level

The system must be protected against frost down to about -25°C, or -35°C in arctic climates.

If protection is too low, the amount shown in the table should be drained off and replaced with coolant additive G11 or an additive to TL VW 774 A.

Protection to °C		Amount in litres
Actual Value	Required Value	Expansion Tank
		without	with
0	-25	3.0	3.5
	-35	3.5	4.0
-5	-25	2.5	3.0
	-35	3.5	3.5
-10	-25	2.0	2.0
	-35	3.0	3.0
-15	-25	1.5	1.5
	-35	2.5	2.0
-20	-25	1.0	1.0
	-35	2.5	1.5
-25	-35	2.0	1.0
-30	-35	1.0	0.5

Antifreeze rounded off to the nearest half litre. After road test, check concentration of coolant. Coolant level must be between minimum and maximum marks on expansion tank with the engine cold. At the delivery inspection, the level must be at the maximum mark.

If coolant level is too low but frost protection is adequate, add required amount of mixture.

Protection to °C	Additive	Water
-25°C	approx 40%	approx 60%
-35°C	approx 50%	approx 50%

Note:
G11 and additives marked "to TL VW 774 A" prevent frost and corrosion damage, scaling, and also raise the boiling point of the coolant. For this reason the system must be filled all the year round with frost and corrosion prtection additive.
Particularly in countries with tropical climates the fact that the coolant raises the boiling point improves engine operating safety at high loads.
