Banfrost 2000 used as an engine coolant.

[Balega]

I am looking at using Banfrost 2000 as a non toxic engine coolant. It was recommended to me by the yard, however the yanmar 4jh3e requires a specific non corrosive coolant. Has anyone ever used this product in a Yanmar with good results?. Any feedback appreciated.

Is there something that leads you to believe that BanFrost is less toxic to the environment? PG and EG both have very low marine toxicity, thus the recommended coolant is as "green" as any other choice. Human toxicity may be different, but fish are not humans and their biology is very different.

If you have pets on board this argument fails. In such case good at least to avoid EG which is very toxic to all mammals (and likely birds and reptiles too).

Thin water It's not the environment that concerns me, I would still dispose of properly no matter what I use. My concern is with possible leakage into the hot water heater. I have only had our boat for just over a year, and up till now have been topping up with the green auto coolant. Recently I noticed green slime oozing out of the hose next to the thermostat. I then read a post on the leopard forum about using the correct coolants for the Yanmar engines to prevent any kind of corrosion especially to the aluminum bits. My last boat had a Perkins, and using the green stuff was no issue. The Banfrost is relatively inexpensive too. Thanks for the blog article, this helped me understand the differences between PG and EG I also want to make sure I use a coolant with all of the inhibitors to protect my engines. Phill
