Dillons VQ37

I have a coolant leak coming from the bottom of this coolant fill neck, does anyone by hanged know the part number? Tried to google it but can't find it.

Maybe I'm blind but I don't see it. Can you circle in red where its leaking?

What I do see is the cap is not fully on. I believe when it is, the two ears are parallel to the engine.

Which year? I don't see a capped neck in the parts drawings here:

I selected 2013 Base at random.

Wrong diagram, look at #14/15 here

I still don't see what's leaking in the OP's pic.

I suppose anything is possible, but I don't see how. The water outlet assembly is a cast piece. Developing pin hole leaks is not unheard of but is rare. More than likely the hose clamp has weakened and it's leaking where the hose attaches to the hose outlet. Fix is cheap, replace the clamp. Probably wouldn't be a bad idea to replace the hose too.

Those oem clamps tend to take a set over time, the indents of the original clamp are visible on the hose showing that the clamp has been re-positioned. This can reduce the force on the hose, it also appears the hose is bulging a bit behind the clamp, this would indicate there may be some leaking there which tends to make the hose mushy in feel vs. a hose in good condition. Changing that hose and a new gear drive clamp would be a good plan. When removing that hose check for wear on the aluminum hose connection, pin holes & pitting can form there. If that's the case some jbweld should work. You would remove any oxidation w/ a dremel wheel then fully cure jbweld then sand smooth. hopefully just a new hose & clamp is all that's needed though. If like Jsolo mentioned, there is pin holes in that aluminum elbow below the hose, then that would have to be addressed.

I mentioned that in post #2.

No one reads previous posts?

I did, I just figured that was corrected but
Sometimes it is the simplest things that get overlooked.
Do tell OP!
