Most people don't use any sealant, but I like to use a thin layer of silicone gasket compond on it, sometiems they are hard to sela, especially if the casting is bolwed a little from having been frozen. A homemade gasket for cap is ok, if you buy one get a non pressuerized one or at most a 3 pound one.

:shock: Just noticed it yesterday. But on the radiator cap the distance between the seal on the cap and the seal at the end is longer than a standard cap. So the cap sealed but the seal in the radiator never touched the bottom seal area. No wonder every time I got on the side of a hill antifreeze ran out the overflow tube. Got a new one from my IH dealer today for $12.50
