View Full Version : MD2030 draining refrigerant square bolt and drain cock

"Dear All,

in my boat I have a MD2030 and I am working out the yearly maintenance by myself.

I would like to drain the refrigerant liquid. The MD2030 manual shows a drain cock which is near the oil filter.
My engine does not have any drain cock, but it has a square bolt which is not very confortable work with.

I would like to know if it's possible to substitute the square bolt with the drain cock and eventually the part number of this drain cock.

Thanks a lot,
