Just wanted to clarify something, correct me if I am wrong. Since the 335D water pump is belt driven, enabling this function wouldn't activate the water pump. At most, it would just run the blower motor to generate heat based on the coolant thats currently just sitting in the heater core. Since no fluid would be moving through the system, the amount of heat generated would be very limited (i.e. some benefit, but no where near as much as if more coolant had been pumped through). Is that correct?
