Better rubber cap for radiator port

[east302]

Truck is a 1998 with 350. I had a radiator installed a few years ago and it has a spare port with a rubber cap on it.

The first one leaked after a few months, and the one in the picture made it about a year before it started cracking.

I saw a thread where someone had a more permanent solution for this but cannot find it now. Any suggestions? It'd be easier if it was threaded.

A short piece of heater hose, 2 clamps, and a big bolt or something to stop up the other end.

Exactly what I did with a Camaro I had. For whatever reason, the rubber used for these plugs are crap. Hose, bolt and clamps did the permanent trick.

Not just the comments here. The whole thread devoted to us was removed.

Get some ricerrific silicone plugs, they go forever. Ebay, siliconeintakes, and the like will have what you need. I've been there.

Silicone caps or tee into the upper heater hose
