2.6.3 Engine coolant recommendation
The engine coolant must meet the requirements of specification ASTM D4985.
Do not use a common coolant / 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.
The engine service manual gives further information on coolant application.
