Nope. Checked that carefully too. You see the regular hose clamp in the photo that I tried for a few flights. No leakage from under the hose w either hose clamp. I have the spring clamp back in place now.

Thanks for the input for sure. I’ll report back in couple weeks on how the threadlock works.

... When I change out the radiator next week I plan on cleaning the area w gentle solvent like alcohol. Then blow dry the area and drizzle thread lock around the housing-elbow junction in hopes that it will seep IN and fill the void...

You may be able to improve your possibility of success if you can produce a mild vacuum in the system.
A Shop-Vac temporarily Jury-Rigged to the coolant hoses would allow you to back flush the leak with alcohol.
Green Loctite is designed to wick past in-place threads.
A drop or two with the vacuum in place followed by another drop without the vacuum should guarantee full penetration.

Interim report: drained system,cleaned the elbow area, created a vacuum in the system opposite the leaky elbow, applied green Loctite. Will give it a few days to set up before refilling coolant.

Will report results in a few days. Hang tight..

Report: the green loctite fix was partially effective. The drip/ooze has been reduced by 50%. Going with that for now and will keep an eye on the situation. Thanks for input. Back to the skies...
