Is it ok to put water in coolant? I live in a tropical country in Burma and i wonder if its ok to put water in a coolant? Also my coolant water fluid does drain every week. Is my coolant functioning well? How often to fill out water in coolant? Thanks
Firstly, if your coolant is draining every week, then you have a major leak somewhere, and I'd recommend you get that fixed first - otherwise you may find that you run out during a journey and overheat your engine, which could result in total engine failure.
Secondly, I would not recommend putting ordinary water directly in the coolant system for any length of time - it is better to use the recommended mixture of coolant and water - the coolant has a variety of additives etc in it that help to prevent the system from corroding.
