Right antifreeze for M-37?

[Halfdunn]

Ok, searched this forum for antifreeze recommendations and cannot find an answer. Any help?

Charles Talbert filled mine with a green coolant. Modern engines have a lot of aluminum, and need "special" concoctions, but ours are just iron, so likely do not need a special coolant. Just my opinion, but I would think one that says "suitable for all engines" would be fine. Just my thoughts on the. Hal

Agreed. I run Prestone in mine.

last evening an add for Peak "antifreeze" popped up on my computer, about how to select an appropriate coolant for one's vehicle. Check the Peak brand out. NV
