I have discovered a coolant leak where the water outlet (19315-PR4-A01) bolts to the head on my 01 CRV. I am trying to find out if it gets a gasket or if I need to use gasket maker before take it off so I can have what I need on hand. Honda's parts diagrams do not show a gasket so I'm assuming it is to be a sealant of some sort. I've tried to attach a picture but for some reason I can't. Can someone please give me a confirmation as to what to use? Thanks.
