Toyota Aqua engine/radiator coolant level dropped

[samk03]

Dear Guys, My Toyota Aqua's engine/radiator coolant level has dropped. It is currently between MIN and FULL mark. Should I drain and fill or refill. Also guide me which coolant to go for.
I heard draining and filling is a tough procedure. One needs to evacuate the air by turning on the heater, then again turning off the car, letting it cool down then again filling and repeating the procedure several times. Please guide me

First thing first
Check where the water went?there must be a leak somewhere and as u said water has ended then just fill after getting the level dropping problem fixed

It has not dropped below MINIMUM mark. It is between MIN and FULL mark. Just half between both the marks. I refilled in radiator cap. It just consumed 50ml. I would like to know should I refill the coolant bottle till FULL mark?

As per my knowledge its normal for the coolant to be between min and max. Just keep an eye on it. Because after the car is used the coolant will warm up and expand and you will see the level to be at max mark, if extra coolant is filled, it will spill out of the overflow pipe. Also check the level when car is cooled down. If the level is not dropping below minimum its normal and no need to worry.

True. Once i filled up the coolant to max level. And after few days found it back between min and max and residue of coolant at the end of overflow pipe. After that i left it as it is. And it has been at the same level since.
