replacement thermostat golf 3 1.8 gasoline 75km what and how ??

Hello.
I have a question how to replace the thermostat in golf 3 1.8 gasoline? What do I need? I know the channel well and that you need to unscrew the pump, but whether unscrewing the support pump will not run off the liquid ???? Thanks in advance for reply.

Hello. Go down the lower hose towards the engine. You unscrew what the hose is inserted into and the thermostat falls out. It is so on the peasant's mind.

More precisely, it is located in the water pump, in the pump nozzle to which the lower hose is attached to the radiator. Pull out the liquid before extracting the thermostat.

Put the pump on the wires, let it hang. Basic tools 13, 16 sockets, 10, 13 socket, maybe something there, I do not remember.

Dziekowa, I already did a little bit of fun because I thought that some old one kept because I did not want to go down but it was enough to move and let go of that paw every other one is 16 and the rest has gone without a problem a new liquid and a new fluid to support because the other one poured over the wire: by the way, it's a bit weird that the support cord comes in just a little and there is some strange security because there is probably pressure and that it will not go away?
