Its not cold here yet its still 8 or 9 C above freezing so when it does come it gets real cold immediately like someone switched on winter. I have tried 3 different types of stats but with no success it gives the impression that there is no circulation but never overheats. I'm going to try blanking off the radiator and see what that does but I shouldn't need to at this temp. What is the difference between a 2wd stat and a 4wd stat I cant get my head round it. Another thing is why is the stat in the bottom rad hose not the top hose like any other car. To my mind the cold water returning to the block would close the stat.
