Doesn't hurt to go with a flush. Do the flush just on the heater core though so you can pour special heater core cleaning liquid into it. Let it sit as directed, then flush out using compressed air the opposite direction. So through the way the coolant would come back to the engine. This will for sure remove about almost everyone out there. Hope that helps!
