[C320-list] Which coolant for Yanmar 3YM30 in Australia?

[sail-ability sail-ability]

Any of the Prestone new antifreezes are compatible with the engine 
metals. I use the premix as it's easier to use. These products are 
lifetime limited so every other year, I drain the engine coolant from 
the spigots designed for this and refill the engine. This is not a 
complete coolant change as there is still 4L or so in the hot water 
heater. Draining the hot water heater is a bit of a mess and not 
required. Adding fresh coolant to the engine every other year or so, 
works to keep good coolant in the system.
