'96 Explorer, V-6, auto. trans.
I noticed a slight leak where the upper transmission cooler line comes thru
the plastic radiator. It appears around a large washer and large nut that
seem to hold the unit into the radiator. Before I dump a can of stop leak
into my new antifreeze, can this be remedied by loosening the large nut and
washer, cleaning the area and applying some silicone sealant before
retightening the fasteners ? TIA
