Since Summer is approaching now. and AC will be in use after few weeks, tell me how to drain and refill radiator in a right way??
the white plastic tap at bottom of radiator is risky to open, coz I have heard that once its broken, its not available in market and radiator will have to be tapped with epoxy resin.
About 2 years ago I opened that tap, the cheaper rubber seal inside got broken, then I threaded the tap with "nalki ka dhaga" and leakage stopped....it was bit mess at that time..
now what should be the right way for draining radiator water?? and which coolant should be used? any good brand?
