suggestions for plugging/capping acoolant flange?
Running along the passenger side top of my 5.0 L SBF I have two coolant tubes that will feed the heater. One of the tubes has about an inch long flange for a hose to the EGR/throttle body that I will not be hooking up. As this flange will be under pressure, I was wondering what are your suggestions for capping/ or plugging it? I put a rubber vacuum cap on it about a year ago(along with several others on my intake) and they've all dry rotted to the point of falling off. So, I'm not confident in going that route again. Thanks!

I don't remember how far along the tube the egr nipple is, but if it's toward the end, it might be just as easy to cut it off short, removing the nipple, and run the rubber hose a bit longer. If it's in the middle, you could cut it out and replace it with a small section of hose, or replace the tube completely with a new piece without the extra nipple. They do look a lot cleaner that way than having big ol' ugly hoses running all over the top of your engine.

What i did on my 32 Ford , was machine up a plug/adapter , that was tapped for a pipe fitting, installed it in the freeze plug hole in the back of the right head , , and plumbed the line in there , cut's down one hose altogether ,,,,,,,,,,,,,,,,,, if running a "brand X " motor , you can trade the temp sender hole plug in the right head , for a fitting , and plumb coolant there , again a much shorter/neater hose run , just a thought ,,, Jim P ..

Pretty sure that earlier 5.0's that were carb'd used the same pipes but didn't have that nipple. Check with the boneyard. Otherwise, since it's steel, you could smash the nipple end flat and weld it shut.

They make freeze plug (weel plug) type caps in a huge variety of sizes. I'll bet you could pull the nipple out and find a cap that would press into its place.
I had to do that with the A.I.R. fitting on the heads of my Caddy engine. The AIR tubes came out of the heads and left an approx 9/16" hole. I went my local machine shop with the precise measurement and they fixed me right up. Clean and simple
