I have a Siena S 2000 and water problems

The water throws me through the reserve bidon to the few blocks but does not lift temperature I have a few days ago and I do not understand much of the subject because I came from old cars. Please if someone can help me would be very useful.

Hi Beto, for what you say you must have the Board blown. Maybe they overheated it, it would have to appear in the recovery vessel traces of oil and in the emulsion engine (oil with water). Greetings

It may be the Curatata Board that would be more serious.
Or the other would be only air in the cooling circuit.
Luck.

Thanks for the answers. Yesterday I cheered and disarmed the thermostat and I was empty. I changed it and improved a lot. He threw some water but it was air in the circuit. Sorry in the heating in progress inside the cabin. Check water and oil and do not seem dirty so I discard the Board for now. What is not like to purge the water because I only found a piricon in the radiator but the heating is higher. I would appreciate help

By putting the refrigerant fluid the alefaccion must be open, so that it does not remain with air.
