Salam...have been using water as a coolant in my cultus carb for almost a year....changed the radiator because it had started to leak..changed it with a chinese one.. .was recommended to fill it up with water...was told that leakages occur due to coolants...now my question is should i change it back to coolant or is it too late. I'm facing no issues at the moment but i worry about the rust build up and the water body etc expenses.
