I checked out the fittings and they were fine for the time being. Bypass hose fit great too, think the other was the original so it was quite a bit differentbecause it was will past it'* day. Replaced upper radiator hose but held off on the heater hoses because the end in the firewall didn't look real easy to get to.

I replaced thermostat housing and am waiting on silicone to set to pressure test again.

I pressure tested before and the bypass hose was definitely leaking. My current radiator cap days 15 psi, is that correct for this vehicle? Not sure if it'* original. For how fast the needle dropped on the tester I can't believe I had to add coolant as little as I did.

If it looks fine for the time being, I would replace it before it breaks on you. Seriously. Maybe add it to the todo list for when you replace the heater hoses.

Doing a cooling system overhaul next weekend. Replacing radiator, upper intake, and water pump (gasket is crumbling, so I figured I'd take care of it while I was on there).

I asked autozone for the metal fitting and there were a million options. Can anyone help me locate the correct one? What is the length and diameter?

Great! Thanks!

Is the bypass one the only one that needs the plastic to metal conversion, or are there others while I'm at it?

That is the only one I know of. I haven't heard any mention of the fittings going to the heater hoses, so I assume they are metal. You will know when you get in there to change the heater hoses.

Yes, but once my car is taken apart, my only reliable transportation to Autozone becomes my bicycle. I think I'll grab a few extra.;

It seems like the better sealed I get the system, the more leaks that pop up! Heater hoses are leaking now too. The back connections look like they could be a bit of a bear to get to, but I'm going to give it a try.

Any preference on clamp styles? The hand tighten ones are great, but I'm not sure I can get them as tight as they need to be. They also don't work well in tight spots.
