I was working on stuff and bumped the (overflow?)fitting and it now leaks. It looks to be a pressed fitting(?). Can I remove this fitting, tap out the hole and replace fitting with a brass thread x barb fitting? What is the bad thing that might happen? Is there a better way to emiminate the leak?

That isn't the overflow. Yes, it is pressed into place. Because these can be such a pain to deal with, I recommend seeing a tech that has the tools and equipment to repair it. As far as a barbed fitting, it won't work. It looks like the steel hose was rusted and when you bumped it, it broke.

Ok, what is it called?

Why could I not remove the damaged fitting, tap a pipe thread into it and use a threaded brass fitting with a barbed end for the hose? Why would this not work?

Is the 90 fitting not just a press fit into the aluminum?

Yes it is pressed. I must have misunderstood you. If you can tap it, that should work.

I removed the throttle body and the coolant fitting broke off. It's ok because it makes it easier to work with. I'm thinking a brass 90 degree male thread x 1/4" barbed hose adapter will work. Will it?

While drilling out the hole for a 1/4npt tap, I noticed a green ring of hard sealant.

I'm assuming that is the stuff used by Ford to help hold the fitting in place and also to seal the fitting to avoid coolant leaks?

Anyone know if this is Loctite and what Loctite part number it is?

Yes it should work. Honestly, I can't tell you if that is loctite, but it's purpose is exactly what you explained. Since you are threading it together, teflon tape should take care of any concerns for leaks.

I ended up using the teflon tape. Let the engine run for about 1 hour with a/c on. No leaks. Thanks for your help. FYI-I received an answer back from the Loctite guy. (after I had already retapped the hole) Here's an excerpt of his reply"...Jerry,
I would suggest the Primer N, 7649 for curing on aluminum. The 680 is good up to 0.015 gap fill. (slip fits)..."

It looks better than OEM, and I'm sure it will last longer. Take care and thanks for using 2carpros. Com.
