i buy 3.__ litre gallon as it was written on the gallon that it was pre mixed i search on internet that pre mixed not require water mean you don need to add water water is already mixed in that and price is around 3500 to 4000.
yesterday i buy 1 litre bottle around 1100 and on back it was written that 50/50 mix of water and coolant. Then i discuss the same person in toyota he said your car is old 2004 be care full add 1 litre of coolant with RO water is enough. More coolant might cause any damage internally.
well first time i buy 3.__ litre gallon and i take out water completely and add the galoon in the radiator after some time i saw there is a minor 1 drop leakage from flenge which is connected to the block.
Then after changing the thermostat and flenge now i am taking information what to do but no proper guide.
Technically 50% coolant and 50 % water but my car is old and the person is said just add 1 litre its enough
according to him "dekhna color ajae pani mien chiknai ajani chayie bus kafi hai hum log be porani car mien yeh he kartay hai ziada coolent sya internal leakage na hojae"
And coolent is also very expensive i have already wasted 3500 now i am taking care of that before doing any thing will study and take suggestion.
