Ok, I have been having this overheating problem. As you all know. I changed the cap, therostat and everything. I was driving my car yesterday I could smell coolant burning. I opened my hood and followed the scent. Where the upper radiator hose connects to the engine. There is a little piece that has two bolts on it. The seal around that piece is done, and their is a leak coming from it. Does anyone know what that piece is called? It connects the hose to the engine.

 

Water outlet cover:

 

Is it the hose that's leaking at the outlet cover or the cover to the head ?

There is no gasket there, just sealant. Just drain the coolant down a bit, remove the two bolts with a 10mm socket. clean the matting surfaces, apply a small bead of silicone sealant, window caulking, to each surface, let it sat up for about 10-15 minutes and install the outlet. Run the bolts down until some of the sealant squeezes out, stop for a few minutes. After about 15 minutes tighten the bolts. Refill the system.
