Not sure what he means by a 'gutted' thermostat, but if the thermostat now allows a significant amount of flow increase, water temp could be very deceiving. It is kind of anti-intuitive, but more flow can make for less heat pick-up in the head, combine that with the inherent greater efficiency of a radiator to shed heat (much more surface area compared to inside the engine) - you could have a overheating engine and cool water temps.

Trust the BMW engineers. Look elsewhere for a solution.


I think the thermostat is designed to open at a certain temp and allow water from radiator to flow to the engine. I believe that if you open the thermostat all it does is just allow water to flow even during start up and maybe in countries like mine where temp doesn't go below 25 celcious we wont need it.
