VW GOG 1.8 thermostat problems

Good afternoon gentlemen.
I consult them again because I have problems with the thermostat of my vw goal; I want to change the thermos ... myself but the mechanic tells me that you have to purged the system so that there is no air in the engine that means this. They advise me to change myself or leave it to the mechanic.
Very grateful for your answers ....... Thank you.

Hello, when you change the thermostat you will empty the radiator changes the thermostat and fill the radiator waiting for it to go down a little and load it a little start it and when it is going to go down the level and load it not to the top but to the max level that indicates you and ready.
Have luck. Greetings.

You can change it yourself but you have to keep in mind that you have to purge the system (take out the air inside the engine circulation system) If you have doubts, consult the manual or take it to a mec. of trust.

Knights thank you very much for your contributions and I will continue your recommendations .... Thank you.

To purge the Gold, just fill it with water and you have walk the vehicle, make a little water as it goes down, but do not put the water depocyte lid expects the electrventillaist to start three times three times turn off the car and wait a few minutes or let it rest until the morning the level and fill if necessary, it is nothing from the other world is very easy
