Need help identifying Radiator part
Noticed 2 hoses were broke and the part looks pretty easy to replace if I just knew what it was, the hoses arent leaking fluid or anything so I guess it isn’t a big issue
This is bolted on top of a radiator hose
It has 2 connections that broke off
One connection goes to throttle body, other goes somewhere under the coolant intake?
While the car is running these hoses aren’t functioning, no suction or fluid in them

I think that has something to do with the "cold start" signal. This is one reason you should always tell what year your car is cuz, although the engine is still a 1UZ, they're different between years. My 93 doesn't have that sensor like your 90 does. It gets hard to remember what year everyone's car is.
If you're gonna change that be VERY careful getting it out. Use PB Blaster on it before trying to remove it. I tried to change the sensor for the temp gauge on mine which is on the other side of that same crossover pipe, near the ECT sensor, and it snapped at the threads, inside the crossover. When I tried getting the broken part out, with an easy out, the whole side of the crossover pipe broke and the broken sensor piece fell into the engine. Long story short, if possible, I took off the crossover and removed that piece out of the engine. (I got very lucky) That was some MAJOR work and headaches. The crossover pipe is aluminum and the sensor is brass bottom and plastic top.
Off topic a bit but what color is the coolant in your overflow tank? Hard for me to tell but It looks empty but then again it looks over full.?????

But I’m wondering how important this part is because there’s no fluid moving in those lines and I’ve been driving without it for a while
Edit: Those 3 lines on top of throttle body are labeled P R E , the P line is broken and I can’t find any good info anywhere

Ah I always forget, mine is a 1990, and I guess I got lucky with the temp sensor because it came out fine other than crumbling into a 100 pieces due to the age and giving me a check engine light
my coolant just looks like water with a pink tint
never touched the coolant system on this car so it for sure needs maintenance.

Yea those sensors, the ones attached to that crossover pipe, sure do crumble when they come out. Such as the ECT, gauge sensor, and the one ya took out, they all get corroded from being in there for 25-30+ years. Ya need to be careful installing them also. Just snug tight, do not put any torque onto them, or they will snap in half. They're only a thin piece of brass.
Your coolant should be the pink, for some reason it looks a bit black to me. If it's been a while you should at least do a drain and fill. http://www.lexls.com/tutorials/cooling/coolant.html
A flush is really up to you depending on how bad it is.

But my engine light is for code 22 Coolant temp sensor, after replacement I disconnected my battery to reset codes but still had code 22 probably because it’s a weird aftermarket part but I don’t think it’s hurting anything?

Awesome, I found a replacement part and some more info on it and it doesn’t seem too important I have worse issues

As for the code 22; The Engine Coolant Temp sensor is the most important sensor for the EFI system. It sends a signal to the ECU which decides how much fuel to use.
It was nice way back when engines had carburetors.
