How do i fix that
 

Where did that come from?

I have never seen one broke on that side. Looks like it is time for some liquid steel and thread repair. I guess it could be welded and re threaded, but I am not sure if it can.

I see JB weld in your future.

jb weld and a helicoil

Would I be able to pack the area with jb weld first and drill n tap it after it drys ? Will jb weld hold or crumble

Wat kinda engine


What still has a h in it

If its open into the cooling system below where bolt would thread into .Drill thru and tap new threads apply sealent to threads of new bolt . Reinstall housing do not over tighten.

Well I put the bolt back on and jb welded it last night I'm going to pull the bolt and rtv the hell out of it

Cross all fingers do a dance ,spin around and say some magic words I think that might work lol

I'd be surprised if it doesn't leak no matter what you do to try to repair it.

But I hope you can fix it.

It was jb welded and rtv to hell and back befor I took it off to replace the thermostat so I think I'll be able to get it to work maybe. All I can do is try, wait, and see what happens

This is how I have seen several vehicles been repaired. I even did this on my 65 Chevy P/U when I first got it.

Well done now I need to wait till tomorrow to check it

Good Luck! I hope it works.
