heater T pipe

Has anyone totally removed the heater pipe from the engine? My car no longer has heat or a beehive cooler and I'd like to not have that pipe sticking out of my engine. Any one know the size of the hole left or anything?

I think it's 1/2", but it's probably a metric size. I ended up getting a 1/2" rubber plug designed for boating applications with a screw thread mechanism and washers which compressed the plug when you torqued it down - never looked back, and it never leaks (knock on wood!).

Last radiator rebuild done at the same time, I had them braze off the connection to the heater feed pipe at the lower radiator bung, and now have no heat in my -7. I live in the Sonoran Desert, so heat is not really one of those things I miss very much.

If you find a good solution that doesn't require a lot of effort, I'm all ears. The solution I found is kind of obtrusive in the engine bay, and I know it's not bullet-proof, either.

its going to be metric. the old 81 and earlier cars had a threaded hose nipple, so on those its easy to block off, you just buy the bolt.

if you don't have the screw in one, the hose barb is just pressed in, so you can pull it out and put a freeze plug in there
