Dear all - i am asking a question for which i had laughed my self but now seriously thinking as what have made these local mechanics think in this way.
i wanted to change the water from radiator and insisted my mechanic to replace with coolant. he advised me not to do so as cultus vehicle engine is made of delicate material (silver) and the coolant will deteriorate it. what he sounded was that coolant acts as acid in the engine.
now could you guys confirm and whats the logic behind his statement?
