Hi Guys,

Complete newbie here. I just purchased a 1977 Yanmar YM2000 and for the life of me can't find where the coolant drains from the radiator. I need to flush the cooling system....Hopefully someone can help!

Thanks much,

John

Thanks for the reply. I'm still not able to locate even after looking at the diagram. Is it possible the drain hole could be plugged?

Here's a picture for reference. Shouldn't it be in the area of the white circles?

On the other side of the radiator.

It probably does'n't have one. you drain the block or lower rad hose, at least on my YM2000B.

Yes that is what i was thinking. There's no drain plug. Only way to do it is remove lower radiator hose. Thanks.
