Which coolant is best for cultus?

[Djaymx]

Cultus has copper radiator, either get suzuki premixed coolant 500/L (4litres) or just add 1 bottle of caltex orange coolant into 3L of distilled water (or AC drain water if its cleaned or filtered again that would be much better).. later being the cheapest option.

Use only Toyota coolant as it is premixed. No need to add water

Actually coolant in which u add water is not preferable, I have experienced it. In my office, my colleague used to dilute with water but water in office was of boring which is common in Karachi. This hard water disturb quality of Coolant and also damaged engine
