1996 Silverado, 5.7 liter, I think heavy-duty radiator. This truck has a small (3/4") rubber cap clamped over a nipple on the radiator a couple of inches below the radiator cap. It split yesterday and soaked me. I've looked on all sorts of parts diagrams, and its now shown. Anyone have a clue of what its called or a part number? Thanks!

Thanks. Since the nearest shop is 25 miles away I came up with a temporary fix this morning . . . a short piece of 3/4" PEX plumbing pipe and a plug. I noticed the factory clamps were Cinch clamps like used on PEX, had a clamp tool and nothing to lose.

It's not the overflow, but is directly below the overflow fitting. The actual size is slightly smaller than .67", since that's the ID of 3/4" PEX pipe. The Clinch Clamps were identical ones with what I use to plumb PEX piping. I suspect Old Wrench is correct - it was put there for some special application used by another vehicle. Next trip back to civilization I will take the rubber hose cap to a Chevy dealer and let them scratch their head. I'll still take my truck over my sister's CTS Cadillac any day. It cost her over $200 to have a front turn signal light replaced. Yips!
