Gracias desde Chile, me sirvió mucho, estaba buscando la tapa del radiador 😮, pero parece que solo se hace el relleno y cambio desde el depósito. GRACIAS
So that you don't trap any air in the system start the car and let it warm up with the cap OFF of the coolant reservoir. When the engine gets warm keep squeezing the radiator hoses to burp air out of the system. Always check the level every day for a few days to see if the level goes down from coolant replacing any air pockets.
