Overheating problems in my 2000 GTS and I need more opinions

So I got my Intake manifold ceramic coating and it was off the car for about 3 weeks. So I put everything back together and start driving and did it get warm fast. It was overheating really bad. This is what I dont get though. I turned the heat on and there was nothing at all it was actaully ice cold. So right away the only thing I can think is the two coolant hoses on the throttle body. I dont remember which side is which but I put them on in the logical way and I need another opinnion. If anyone has any diagrams of these two hoses which are connected to the Idle Air Control Motor they would be appreciated. The other thought in the back of my mind is thermostat because I had no heat at all even though it said my car was really hot. Trust me it was so it in not the coolant temperature sensor. Another thing is that the hose right after the thermostat housing was not even warm. So this makes me think that the thermostat is stcuk closed which would make sence. What I dont get is why the heck would the thermostat get stuck closed when the car is layed up for this amount of time. If anyone has any suggestions let me know. I am going to finish this project after the coolant gets colder.

HELP!

under the Intake manifold is a coolant line. it's very easy to pinch that off if you're not careful. might wanna find that hose and make sure it's free.

I am taking it in to get the coolant exchanged because I am pretty sure that I have an air bubble inside the system. I need a pressurized machine to get it out thus it is going into the shop!

The thermostat would not "get stuck" in the period of time your car was dead or probably for some laid off years. You can cancel that out as you already have. Might want to check it out any ways, but I don't think that would cause the car to over heat by the words you wrote.

A "bubble" in the coolant isn't a thought that would incline myself to think overheat like you described.

I have let my car sit for months longer than you. I have a "bubble" in my coolant for 4 years plus and still do.
That's not the problem.
I hope you can get everything up and running not good, but great again.

try checking the heater core lines behind the motor that go into your firewall. One of those may be kinked because your heater acts like a mini radiator and should help cool the car if the heat is on full blast.

you opened up your coolant system, and now you have air in it. depending on how much air is in there, it can cause it to overheat. if you have a stock Hood, look for a sticker under it that details the bleeding process.

you dont need to do that.

the problem with the 2zz and 1zz coolant systems are that the overflow containers are not the highest point in the engine (like they should be) due to the low profile Hood.

you need to bleed the air out of your coolant because when you poped off your Intake manifold coolant leaked out and created lots of air bubles this is causing the overheating.

remove the overflow from the radiator support and stretch it up keeping the rubber hoses connected, you want to get it as high as possible so the air will bleed out the system. Its best to use several bungee cords and attach it to the Hood latch with the Hood up so you dont have to hold it.

continuously keep an eye on your overflow and keep a bottle of 50/50 handy to pour in more should it start to get low, massage the 2 main coolant lines that go into the radiator also (make sure car isn't hot before massaging lines because they will be hot)

it usually takes about 30 min to "properly" bleed the system.

It worked! Finally it worked. I kept the bleeder open with the car running and some antifreeze went out the top along with millions of bubbles. It just takes a lot of time that is all!!
