   BUT... I bought the thermoswitch I was talking about in this thread, and it seems that even if the diameter is correct, the original switch is different... sorry I didn't go further,as my radiator was in place and full, so water was pouring everywhere and I was not able to take pictures of the switch before refitting it [:(] !
