[C320-list] 3YM-30 Transmission Oil

[John Van Vessem]

Al,
   
  I understand your concern, but I have not found it to be a real issue.  When I switched to the orange coolant 3 years ago it was by the recommendation of my mechanic, who specializes in Yanmar

the new orange or red coolant is supposed to allow you to mix it with other coolants witch wasn't possible with the green stuff it also contains a lubricant to protect the water pump--but -- there has been many reports that the lubricant has gelled up and caused many coolant system failures ---check with your local mechanic first
