So I have this problem with my car. It overheats. I HAD an Aftermarket aluminum Radiator and Electric fans, and that too would overheat. The only way it ran right is when I drilled a large hole in the thermostat. It would run about 120 degrees no problem. But I got crappy gas mileage and I hardly had any heat.
I got tired of the super cool set-up and reverted my cooling set-up back to stock. I never had a problem with stock, the only reason why I upgraded to an aluminum and e-fan set-up was that my previous stock set-up took a crap. (Clutch Fan blade in the radiator).
So Now I'm back to stock, OEM everything, and have been through Multiple OEM Thermostats. It still overheats! I gave up and took it to a shop (working 86 hours a week sucks!). They are having a same ordeal as I am.
It appears that the thermostat does not want to open up and carry coolant through in a normal fashion. The upper hose and radiator are hot to the touch, and the lower hose, and thermostat housing are cool to the touch. It is almost like the temperature extremes on each side of the thermostat; make it not want to open...
They tested the Coolant for Hydrocarbons, and there was none, so it rules out the head gasket, they have bled it numerous times and are just as stumped as I am! Please Help ME!

Re: Thermostat Problem!
Check radiator cap (store can do it)
Pressure test the systems
Then bleed it.
Coolant bleeding
Jack the front of the car up front tires off the ground 4-6 inches.
Take off radiator cap
Take a 2 liter pepsi bottle cut it in half and use some black electrical tape and wrap the bottle neck a little, or get a cooling funnel
Flip it around and place the bottle neck were the radiator cap was at. Pinch off over flow line if not using the funnel.
Now start filling it with coolant about half way
Remove bleeder screw
Close bleed screw after you get a nice even stream of coolant
Squeeze the upper, and lower lined and burp out the air
Add antifreeze until you over fill the rad by a quart
Turn the heat on full blast
Start the engine and let the engine run after 3-10 minutes the thermostat will open and suck in the excess antifreeze (ambient temp affects time)
Fill it again but with about a half of quart.
Let it run until no more bubbles come out. Squeeze hosed time to time.
Replace cap, unclamp overflow hose and then shut off the engine, fill over flow 1/2 to 3/4
Coolant funnel (best to have)
Pressure test the systems
Then bleed it.
