Need fix for radiator
I changed the idler/tensioner, and broke the overflow nipple off of the radiator putting the shround back on. Probably not a fix for this since it's plastic (thinking self-tapping-bulk-head-fitting) but I'll probably end up replacing the whole unit.
Anyone have a fix, or know where I can not spend $400 for a new one?

The 1/8 npt nipple works.. I did it after testing the load bearing weight of the original plastic nipple..
Test results: The plastic nipple will not support my full lean on it like an idiot weight.

There was another video that shows taking the fan off. When he goes to re-install it he was underneath pulling the tabs out to get the shroud seated correctly. Well I was underneath pulling the tabs out the get the shroud seated correctly.
Sometimes things just don't work out. No matter how you prepare, or act.
My only worry is that when I tap into the plastic that a little piece will end up in the system. Given my luck it won't matter because this will work, but I will end up getting hit by a train.

Don't use the epoxy, it won't last long (a few months). Use something specific for radiator repair (available at your local autoparts store) to use as a thread sealer on your nipple after you tap the hole. Id also recommend going in with a plastic fitting like nylon as opposed to brass. The brass will want to separate from the radiator material and thread sealer over time as well. Or at least this has been my experience.

Only thing I'm worried about is the galvanic corrosion between the copper and aluminum. Time will tell. Going to try it tonight, and I'll let you know how it goes.
It wanted a 7/16" hole for the tap, but I only had a 3/8". Right angle drill to get that in, and some pipe dope and all is good. Ran it around to really warm it up and it didn't drip a drop. Call this a win.

Galvanic corrosion would only be a problem if the metals were in direct contact with each other.
To confirm the earlier poster: Just about all retail epoxies are not waterproof and will fail in time with hot water.

Correct. With water above 200° the solubility will increase enough to allow more than usual amounts of copper to dissolve within the water. This will inevitably come in contact with the aluminum of the radiator and therefore we act in manner as if it was in direct contact. I would have preferred to do a plastic fitting, but home depot didn't have one. I will end up bullet proofing this next winter probably, so I don't have to worry about it long term.
I do agree with the epoxy. Unless you find one designed for use underwater it will fail rather quickly. That would be a short term fix, mine a moderate interval, and a plastic the indefinite.

I never noticed that. Guess everyone has to make a few bucks huh.
Down the road I'll bulletproof it, but this will work for now.
