Did the carrot test on mine with engine warmed up :doh.
Might try it again with cool engine sometime after I've cleaned all the splattered carrot out of the engine bay.
Mrs had a laugh at my "orange" complexion
Heater gets warm OK but temp gauge never rises more than about a sixth of scale.
mine never rose above the 1/4 mark even in traffic
depends how warm the engine was if it was just a little warm or running temp it should have stoped i think the fan only come in when the heat is too high and it cuts the fan in
