[C320-list] Tips for Changing Engine Antifreeze?

[Warren Updike]

Each Spring, I drain out about 1/2 gal. and replace with new. My Perkins engine holds 4L (135oz) plus maybe a quart for the water heater. My coolant stays clean and I don't have to fuss with flushing and etc.  This may not satisfy the purest among us; but, works for me.

I'm not sure if you are looking for general approach or specifically for technique on a Yanmar.

Hello,

   I'm looking for tips on how to change the Engine Antifreeze on the
Yanmar 3GM30F.

Last time I did it, it seemed like alot more work than it should have been.

Thanks!
