First time digging into this car, opti replacement & more.
It looks like you have to try pretty hard to not line the teeth / key up correctly when reinstalling. Hopefully all goes smooth between waiting for the opti to come in and work might not be untill tomorrow night or wednesday morning 
Also, anyone know how much pressure it put on the coolant tubes going into and from the throttle body, I did a mock-up of the bypass and just hope it'll hold with a brass fitting and hose clamps.

IT RUNS!!!!! THANKS EVERYONE. I've been working in the dark the last half hour and everything is 99% back on. I just wanted to fire her up tonight and she started right up no problem!
Tomorrow in the day i will be triple checking my hose clamps for leaks and filling the cooling system properly.
Anything I should be on the look for now that this big job (for me anyway) is done. I didn't have tape to wrap around the water temp sensor in the water pump, is it NEEDED
I think other than blocking off the manifolds now I will be set knock wood.

I think I would just tap them out for SAE and use plumbing parts from the hardware store.
always something but if this is it then yay. After making sure nothing leaked, got everything up to operating temp in my driveway and even did the oil real quick took it on a quick drive. 5 Minutes to my friends house, then 5 minutes back. When coming to a stop in my driveway noticed the temp gauge started climbing... Would air in the system cause this or did I mess something up with the fans when i had them down during the opti swap. I couldn't be sure but i don't think they were on when i got home.
I'm going to let it cool down, start back up and bleed the system again. I'm really hoping that's all it is

Since then I made sure the rad was topped off, took it out for a spin, runs cool while driving around. Then again, let it sit in the driveway, began bleeding the system and still started climbing like in the previous picture so i had my friend shut it off. A good amount of air was coming from the bleeder by the tstat given the lack of any coolant
I'm hoping now as it sits tonight it'll pull coolant from the overflow tank. The heat is also luke warm at best so really hoping it's just air. I'm tempted to put it on ramps when /if i have time tomorrow. I've read it's helped some people but i've never had to do this. So just to update, it will over heat when not moving. Drove it around for 10-15 minutes all around my block not far. If anything it wasn't getting past the 180 mark until i stopped moving. After i let it sit and it got past 210 went for a spin the temp gauge drops. Turned the air on while sitting, temp gauge drops. When i put the heat on it's luke warm at best but that could be a clogged heater core.
(God i hope not) I'm thinking i have air in the system still or a bad tstat( replaced with new one btw) or both. Going to let it sit while i go in for my 2nd shift, we'll see what tonight brings....

Yea 210 is where my previous one ran. It goes past that like inn the picture i posted. Hopefully i cab just get all the air out soon. Is it normal for the temp gauge to fluctuate like that?
