[C320-list] What antifreeze/coolant?

[Rod Boer]

Hi Bruce,

When I spoke with the service department at our marina regarding changing from the green antifreeze to an alternate they emphasized that I should get every bit of the green antifreeze out as mixing some of the alternate antifreezes with remnants of the green produced a mixture that looked like mud. I also flushed maybe as many times as you did although I didn't change any of the components of the cooling system.

I found the Yanmar YG30 locally, I am now on my 7th flush on the engine. I'll be changing all the hoses and the thermostat. There is nothing wrong but I want to prevent future problems plus I'm a little nuts when it comes to my boat. I must admit this is a royal PIA!
