Some Hondas, the Goldwing and CBR1100XX for example, are picky about antifreeze type...the waterpump seals will fail if the incorrect one is used. I don't know if Kawasaki has this issue. Make sure the antifreeze is aluminum safe (should say on the container) and consult your owners manual for type. Call the dealer if you don't have a manual and you MAY get an intelligent response. I have read/heard bad things about Dexcool...but thought that was a Texaco brand?
