Pwd preston kanang green... Naay ready mixed na nga 50/50 ratio or pwd concentrate imo paliton and then imo i mix to 50/50 distilled water...
Pero ako I've been using DISTILLED water since cheaper and i normally get my radiator flushed every 6 to 9 months para ma check nku if naay rust build up... Note that dili Tap water, or mineral water gamiton ha..
