Thank you brother, according to the service manual of santro in pakistan there is 6 litres of coolant required or circulating in the whole cooling system as mentioned by you also. now most of the people says that we should maximum put 2 tin of 500 ml green coolant to the radiator which is 500ml+500ml=1 litre, mean 16.5 % composition with 83.5% water, but the problem is that the manual of santro says that we should compose the percentage of water and green coolant as 40% : 60% for tropical areas like pakistan. means 4 glass of green coolant to the 6 glass of distilled water, now according to my calculations, we should pour 2.4 litres of coolant to the radiator. means 5 tin of 500 ml green coolant. 2 can of 1 litre green coolant and 1 tin of 500 ml green coolant.
now my brothers and sisters i like your expert opinion about my calculations, because i may be totally wrong, so please correct me and guide me if you think some mistake. or the scenario is different from this
thank you.
