It is probable that all viscous type fans are not made the same, technology has moved on since P6 and SD1 days, I did not know that a fan had a heater in it.thats not quite true, viscous fans are supposed to lock up tighter as the airflow going over them increases. in fact land rover discovery 3 has a heating element in it to make it lock up when the ecu decides its appropriate
I am happy that the engine stayed cool and behaved perfectly with the Evans coolant at zero pressure, that is taking a lot of stress off of elderly components.
