@Chance575 is saying that, "the diesel circulates coolant for like three minutes after you turn the truck off. It makes a electric whine that is easily heard in a garage."So the sound after you shut down the eco diesel I thought was the def system purging to prevent freezing ?
Is he wrong or his is right? If he is right, then what makes the coolant circulate? Is there a built-in electric pump?
