Have been driving for 28 years, some of you might not have not been born and I have always been using normal tap water for radiator. Oxidation will still occur even if you're using distilled water. Tap water on the other hand might have some minerals in it but it's there in small quantity so it will not harm your radiator as long as coolant is present.
Hi Golf, lau jiao leh....!
I think we just do it as per normal, follow what you said aso can loh. FOC mah.... that is impt...
Is it advisable to flush the reservoir and radiator in a fixed time interval (time range)? e.g. 2mths , 6mth once?
And, when we chg the coolant, the reservoir will be 'emptied' first and at the same time, the Radiator should be 'flush' before refill new coolant into coolant reservoir?
Thanks.
