Message:
I have a 2000 R/T CC and it will not stop overheating. I have replaced the T-Stat 3 times, put a new upper radiator hose on, checked my head gaskets, and went as far as to take off my M-1 2bbl manifold off and put the factory one back on. Nothing is working it just keeps overheating. the guage will jump all around. It will shoot up to 260 and then shoot down to 210 then down to 160-180 and then back up and down again. It seems to cool down when I turn the AC on and drive it. Not sure what to do please help..

(Assuming 4.7L engine)
If actual engine temp cools when A/C is turned on, then you would think it is only because the secondary electric cooling fan kicks on. That's the only thing that happens to allow better engine cooling when A/C is turned on. If this is the case, it's simply not getting enough air.
Temperature sensors or PCM issues would be the next thing that comes to mind.

Jason-
He stated he has an R/T and an M1,so..5.9L :)

Jim-
The temp. sensor is the small sensor that screws into the water passage in the intake manifold.
You can use a meat thermometer to verify coolant temp. matches the guage. Just make sure to remove the radiator cap before it gets hot!
Also, I agree with 98D, check the fan clutch. There's a procedure for this but I don't know it off hand.
It's also possible, but unlikely, that the pressed on water pump impeller has oosened itself from the shaft but catches intermitently (like a bad fan clutch).
Also make sure the thermostat is installed in the right direction.
Hope this helps.

If you driving down the freeway does it heat up? If it doesn't then check your fans. You should have 2 fans one off the eng and one electric. The electric one should kick on when the a/c is on. At freeway speeds both fans could be gone and it will stay cool.

If it sill does that then it sounds like air in the watersystem. A blown headgasket will do that or not purging the water system after an M1 install.

Mine did that and I found it blown at #7 hole to the water jacket. Good luck.
