well, there was no thermostat. turned out that your supposed to bleed the system....

the water appears to be boiling severely, the mechanic sais the water getting pushed out can be cold because the air is pushing it out. he sais its not normal for it to boil like it is, air spurts out of the bleeder which sits on the thermostat housing with lots of pressure when you open it, he sais seems like a head gasket but we gotta pull it apart and take a look.
