The thermostat to cylinder head gasket came in the kit you bought, it has the same gaskets as the kit I listed. It is not formed in rectangular shape, it appears to be round in the packaging. Replace your temp sensor if you broke it. I did not go step by step but I did recommend taking it to a professional if you were not sure you had the skill set to do this job.
I think you're right, that it's the temperature sensor. I'm not familiar with aluminum putty, but if it contains aluminum it may be affecting the electrical signal the sensor is sending to the ECM. When you say the engine is overheating, are you referring to the temperature shown on the water temperature gauge? This would certainly point to the temperature sensor. Smoke (steam?) coming from the area where you worked is probably coolant and old grease or grime burning off the exhaust manifold. It should clear up after running it for a little bit.
On the P0016, that is a crankshaft/camshaft correlation error. The ECM thinks there may be a timing issue. But on this engine (2.2L) there is no camshaft position sensor, so the ECM has no signal to compare. I seem to remember reading that the P0016 code may mean something else, but do not remember what that is. In any case, replace the temperature sensor, clear the codes, and see if it resolves itself.
I was thinking the same about the smoke clearing up after a while. Will have to see. I have a LOT of grime due to an slow oil leak from somewhere on the belt side but it gets everywhere! I wish I could pinpoint it because I have a feeling the grime buildup will eventually destroy something. Do you know the best way to clean it off of components like alternator, compressors, and starters? Some kind of spray that works like brake cleaner?
As for the temperature, it must have been a hot pocket somewhere. I filled the reservoir a little over the fill line and after i turned the engine off when it started to go a little over the half point. I then eventually discovered I forgot to put the serpentine belt back on 🤦♂️ think that could have anything to do with the code or the temp rising? Or even the blower motor powering off on levels 3 and 4? Probably not likely for the temp or the blower. The blower is still the same. But by the time I put the belt back on and started it back up, I noticed the reservoir had gone down to the exact fill line. I took it for a drive for about 15-20 minutes and the temp stayed under the half point the whole time. I park in a parking lot and it started raising to the half point, then the fan kicked on taking it back down. I think it's safe to say, job well done. 😅
Still gotta figure out the other two new problem I somehow created 😕 Do you think the P0016 could possibly be from me disconcerting the ECM or computer? I had the battery disconnected the whole time.

Ok thanks. I will replace that sensor and gasket at the same time. I think I did pretty good, especially considering how tuff this turned out to be. Thanks for your help!
Quick question. When I used the chain holding tool, I put it in place and screwed everything down, but when I removed the sprocket bolts, I noticed the bolts that come with the tool, that go in to hold the chain in place, were somehow loose. And then, if I remember correctly, when I put the new pump in and bolted it to spec, the tool holding bolts were loose again 😳 I don't understand why or how, and pretty sure it's not supposed to happen, or if it mattered. Do you think this is something that can cause the P0016 code? Either way, the tool stayed in place.
Another thing is, when I out the new pump in, I had to reach behind it with a pic to spin the blade in order to line up the holes. Not anything that would cause any issues, right?
Thought I'd share this. I think this is where it was leaking from. I forgot how the o-ring looked, but obviously, it was deteriorating. So I guess it was a gasket issue and not the actual pump? Either way, replacing just a suspected gasket with all that work would have been crazy.
Anyone know what the stuff the red arrow is pointed at is? Seems like gasket maker but isn't applied all the way around. Could it have come from the o-ring?

Hey guys, I'm back. I know you're all probably tired of this thread, but I really need help. So, I mentioned that after replacing the water pump, I had a few new issues, including the p0016 code. Well, the car was driving fine as far as I was concerned but today, I started it up (I drove it earlier in the morning no problem) after it was parked for hours and hours and it ran for about 30 seconds and just shut off. I tried to start it back up, and it wouldn't start. Every time I tried to start it, it eventually started sounding like it did after a mechanic replaced the timing chain after it snapped years and years ago. Like a winding sound because the head was warped and needed replacing.
I ran my scanner tool and now have a few more codes, p0341 and p0520. The p0520 is related to the oil pressure, and I've already checked to see if the oil level was good, it was. I wanna say the timing is good since I used the timing chain sprocket tool, but with that familiar sound I hear, I'm pretty nervous. This sucks bad 😭
I was hoping it was a battery issue since I know the soh on mine was low, basically 0 at this point. So I had it replaced but no difference accept a new battery.
I also tried spraying the throttle body/intake area with starting fluid, wondering if it was the fuel pump, but that didn't work.
Any suggestions? I can send screenshots of the live data from my scanner tools app that'll help. Is there anything specific anyone would like to see?
I should mention that days before I replaced the water pump, I had this issue where some times, I would attempt to start the engine and it would just Rev, but always started right up on the second try. It never stalled more than once. Always started right up on the second time turning the key. And it wasn't happening always. Sometimes, it would start right up on the first try.

You're now getting a P0341, which is a camshaft position sensor malfunction. I have learned that what I stated above only applies to 2003-2005 Ions with the 2.2L engine. In 2006 and 2007, there is indeed a camshaft position sensor. It's on the intake side of the cylinder head at the transmission end of the engine.
P0016 indicates that the camshaft and crankshaft are out of sync with each other. This code can be the result of an electrical issue or it can actually be a true indication that the vehicle is out of time.
The P0341 could be indicating a bad camshaft sensor, but it seems odd to have just popped up.
Was the oil light on or flashing during the 30 seconds the vehicle ran before starting?
The 0520 is for the oil pressure switch circuit. This may indicate that the oil pressure was less than expected. If this is true, you may have had an oil pump related failure which in turn starves the engine of oil. Which includes the timing chain.
Do a loan a tool for a compression tester from AutoZone or similar and hold the throttle wide open and test the compression of all four cylinders. Remember to remove the fuel injector fuse before doing the compression test.
