You probably lost a significant amount of coolant for it to heat up so badly, if that's the problem. If your radiator and overflow is full, then you have a flow problem of some kind, and a flush might be a possible solution.
Bob, we'd want to check that the temp gauge is actually correct first, before we assume an overheat situation right?

So the thermostat could be running to low and not letting the coolant flow?
Re: Need some serious help before i damage my car.
He is saying you should scan it first to make sure it's not just the gauge that is the problem.
Re: Need some serious help before i damage my car.
I also think everyone is also assuming you just purchased the car, is this correct?

Sounds like it needs some work...either the t-stat is on its way to sticking...fans are crapping out...or the thing needs flushed. Either way, running that hot isn't normal.
Any engine codes?

Re: Need some serious help before i damage my car.
Update: Bought pre-mixed coolant. uncapped radiator when cool, some coolant shot out as there was still pressure, filled with coolant to the top, filled the overflow bin, drove car for 30 minutes on my lunch break. thermostat stays 1/8th under the middle of the gauge, and when running it hard goes 1/8th over the middle. I am hoping this will last.
Thoughts?
Re: Need some serious help before i damage my car.
You did use the same coolant that was already in there correct? Keep an eye on the overflow bottle.\

Exactly, factory gauges are known to be off of many cars. Often referred to as dummy gauges. On my truck its off. It quickly warms to right at 210 and stays there. I put a Dakota Digital Gauge on it. I also ran an autometer of some sort for a while to verify and the factory gauge shows 210 when the truck is running 199-220. It never moves. My truck has never gotten hot, but a few I know who tow very heavy up grades say it stays there and almost instantly goes from normal to 250 (red zone) once its overheating. No warning. I have heard of this with many other cars too. The GP's may not be much better.

There is a brass 7mm bleeder screw on the thermostat housing.
Gonna have to disagree with you. My fans kick in well under the 210 mark. Not until the cars at like 185 mark for me.
Re: Need some serious help before i damage my car.
id get a junk yard used coolant sensor and change it. its the sensor under the t stat in the lim.
new ones are know to be bad new in the box. so either used, or find a delco.
that temp sensor sends two signals, one to the dash gauge, the other to the pcm, the pcm tells the fans to come, and that part works you say cause the fans come on. and it dont seem like its really over heating. so the dash side of the sensor is broken likely.
get a scanner on it, t app is cheap, it will tell your what the pcm says the temp is.

You have an 01', 05' and later the fan does not come on until between 217-219*.

Oh really? Seems kind of dumb in my opinion.
Re: Need some serious help before i damage my car.
true story..... as long as i had a 05 bin open, why not right?

Re: Need some serious help before i damage my car.
Holy crap I hope I never hear the high speed fans. Thanks for the confirmation Scotty I haven't been able to pinpoint the exact turn on temp with my Torque App but that about sums it up.
Jeff
Re: Need some serious help before i damage my car.
Scott...thanks for posting the pic.
That's exactly what I was saying, the fans are programmed for a temp. In the OP's first few posts, I was pretty sure I read that fans were kicking on at a higher temp than seemed correct. Hence my suggestion on checking temp.
Now that you found pressure in a cool coolant system, that is also concerning. I would start by swapping the radiator cap.
Re: Need some serious help before i damage my car.
I would just changed the T-stat as well. Cheap and easy.

Fixed that up for ya
I can check temp faster than a t stat...and I don't wait for the car to cool to do a stat
Re: Need some serious help before i damage my car.
Most of us at one time or another had the fan connector burn out Unplug it and see if it's burnt up inside
