(Do this with engine cold and use a six point long socket to remove the old sending unit) I put permatex hi temp sealer (it is white and has Teflon in it). On the threads of the new sending unit. I unscrewed the old sending unit, but before I removed it I had the new one close by. You will lose a little anti freeze but install the new one quickly and you won't lose much anti Freeze. DON'T OVERTIGHTEN it has pipe threads on it and it needs to be snug, and with the permatex it won't leak.
