Either their 'Factory Line' (same as Yamalube) which is the recommended organic acid technology (OAT) coolant. Their Expert 'coolant' is a hybrid coolant and not suitable and will react if mixed with the original OAT coolant.

All you have to ensure when choosing a coolant is that is marked: 'Organic or OAT and borate and silicate free'. DO NOT use IAT (inorganic acid technology) or HOAT (hybrid organic acid technology) coolants and never mix OAT with either of the others.
