yes I googled and uses the search function: So far I know Mack Boring recommends for Yanmar
Texaco Long Life Coolant
, Havoline Extended Life, Dex-Cool Long or Prestone Extended Life Coolant
So far so good, the problem here in Grenada
is I just get Starbrite Star*Cool or Shell Zone or Shell Rotella ELC. All of them claim to be safe for Aluminium and since I do not know what was used before I need to flush anyway.
Any recommendation with this limited choice? Many Thanks.
