i brought a new thermo & fitted it a few days before, although i did have a core plug leak by the water pump, but i replaced this also. i made sure there wasnt an air lock in the system when i topped it back up with water.there does not seem to be any water in the oil when i checked , but i am going to change the water pump, timing belt,and while im at it the head gasket just in case.
