Well, next day i come outside, the check engine and traction control lights are off, but the car is still getting really warm. I bled the system for at least 3-4 days bleding it maybe 3-6 times a day and the problem still existed, so switched it back to a 195. Well, its not too bad now, but the thing is i was driving it last nite, and the same lights popped on, and then the car just died on me! It started right back up tho no worries. I'm sorry this is soo long, but i just wanted to make sure you guys had the info to help me. Thanks in advance
even if he does take it a shop more than likley he need to have it replaced for future maintinence anyway so you mine as well have it changed out. and what oriblems were you having prior to thermo install??

Says who? What are you basing this on? If it'* plugged, change it. If it'* not, don't.

Can you also PLEASE read this and follow it in your future posts:

ok well, i went outside and tried cranking the car, but now it wont do anything. My girlfriends says that when i tried to start it, the alternator tried to move just a little bit, but not much. So yea, checked the oil, didnt look like anything outta the ordinary so dont know yet. Could it still be a sensor? or am i looking at buying a new motor for it?

So it TRIED to crank (turn) the motor, but didn't?

Pull the front three spark plugs and tell us what they look like. Look for coolant in the cylinders through the plug holes. Check your coolant level, and look at your oil.

yea, it tried to fire, like crank, but it didnt. Nearly like what a dead battery would do, but just without that clicking sound. And i know its not the battery because its new and i replaced the cables on it too. And i tried jumping it as well lol. So yea, i guess i'll try the spark plug thing, but i did notice something. A few of my buddies noticed a good coolant leak coming from the top part of the motor. When i went outside to look at it, it seems like it could be the upper intake manifold. Coolant is all over the ground too

That is probably a bad upper intake. Most likely your motor is bad because of how long it has been sitting with coolant in it. Although..I'd take a good look at the oil and maybe give it a try.

ok well, nothing really noticeable with the spark plugs removed. I cant start the car to see different, but the car now has been sitting for the past week or so, so i dont know if that would make things undetectable as much. Just a question, if coolant was inside there, what would i be looking at to fix my car?

Pulling the front plugs isn't the answer yet. Please pull the rear plugs..with all the plugs out..try and crank it over.
