I guess Mack Boring lacks the conservation gene as well.... :)

Yanmar accepts the following antifreeze applications in their
products<br>present and past models:<br>1. Ethylene glycol-Changed
annually regardless of hours of operation

Here are the answers to questions I posed to Mack Boring about coolant
options for our Yanmar's....

Yanmar accepts the following antifreeze applications in their
products<br>present and past models:<br>1. Ethylene glycol-Changed
annually regardless of hours of operation.<br>2. Extended Life Antifreeze
or Coolant (Meets or exceeds ASTM D3306 &<br>D4985)<br>   Changed every
two years or 250 hours whichever comes first.<br> -Yanmar Ultralife YG30
<br> -Dex-Cool Long Lfe Coolant<br> -Havoline Extended Life
Antifreeze<br>Benefits of extended life coolants:<br>1. reduces hard scale
build up<br>2. better heat transfer<br>3. no phosphate or silicate
formation<br>4. long term corrosion protection for aluminum, bronze and
cast iron<br>5. improved water pump life <br><br><br>Thomas J.

Kathleen Minichini<br>Subject: Yanmar Coolant<br><br><br>I have heard that
Yanmar is now recommending DEX-COOL type coolant in<br>their marine
diesels. My 2000 Catalina 320 has the 3GM30FC that came<br>with Ethylene
Glycol (green) coolant. If we are supposed to change the<br>coolant every
season or two anyway, what is the benefit of the extended<br>life (orange)
coolant? Does the flush interval increase with DEX-COOL?<br><br>What about
using the red coolant (OAT inhibitors also, but with the<br>ethylene
glycol base)? How about the YELLOW (hybrid) coolant? <br><br>Are any
internal Yanmar parts (gaskets, etc) incompatable with any of<br>these
"new" coolants? Did Yanmar redesign anything in the new 3YM30<br>engine to
make it more compatable with DEX-COOL?<br><br><br><br>Bottom line is that
this has
been a topic of interest to the C320 owners<br>and we'd like to know what
to do and why.<br><br>Many thanks....<br><br><br><br>Karl
