Refrigerant-Ayuda Liquid Loss

Hello; I have a 2006 Chevrolet Meriva has already begun to spill the refrigerant liquid by the container it brings to add water or liquid (this happened twice, now it is without walking by caution). I do not remember seeing high temperature indication on the board and the spill does it when the engine stops working. According to opinions found, they tell me that it could be the "thermostat." If someone makes me the favor of indicating where the thermostat goes and if I exchange it. Or specialized hand is needed. Could the problem be another? Thank you

Good night, the thermostat is usually in the motor block at the end of the superior cuff of the radiator, first Manguito is heated, you have to continue obscuring, keep warming the engine and check the electro -ventilator.

Change the container lid, that problem is common.

The container lid, I agree with the previous colleague, is the most common fault and the easiest to eliminate

Do you have a round boat with yellow lid or the other rectangular container?
