Tab. 35 Water quality parameters for cooling water
Contact the local water utilities for information about the water quality. If the water does not meet
the parameters above, it must be treated.
Coolant quality:
The coolant (cooling fluid) is treated by adding anti-freeze with corrosion protection additives on the
basis of ethylene glycol to the water.
The engine coolant must meet the requirements of specification ASTM D4985.
Do not use a common coolant and/or antifreeze that meets only the requirements of
ASTM D3306. Such coolants are intended only for light use in vehicles and could shorten the
useful life of the engine.
