ENGINE COOLANT
The coolant solution must be a mixture of 70 > 50% fresh
water and 30 < 50% anti-freeze. This requirement also
applies to warm and tropical climates as the solution
additionally helps to prevent overheating and corrosion
forming within the engine cooling circuit. The anti-freeze
in the fresh water system enables the boiling point of
IMPORTANT!
Always use a Mono Ethylene Glycol Based
Extended Life Anti-freeze must be a mixture of
30 < 50% anti-freeze and 70 > 50% fresh water.

WARNING!
New engines are supplied with the engine
coolant drained off.

water to rise to 124°C with a 13 psi pressure cap fitted.
The water temperature alarm switch will however be
activated at 95°C to 100°C. If no anti-freeze or a very
weak solution is used, then the water temperature switch
may not be activated before coolant is lost. Warranty is
invalid if the correct percentage/ratio is not used.
IMPORTANT!
Do not exceed an Antifreeze mix greater than
50%, as the engine cooling efficiency will be
detrimentally affected.
To initially correctly fill the engine closed circuit coolant
system:
a) Check that the coolant drain tap or plug is turned off.
Please refer to image 33.
b) Fill engine with a correctly mixed engine coolant
through the top of the heat exchanger. Please refer to
