I have a 2001 Pontiac Aztec I've had the radiator, radiator cap, and tempostat replaced. And still over heats. So the problem.

yes and no. it may that the button is broken or the conection is bad, or it just might need an entire new system. you might want to get all of those things checked out

Sounds like Clutch in your fan

The coolant level is right on, no hoses are leaking and the accessory belt is intact. You start the engine, let it idle and make a visual inspection. There's no sign of belt slippage.
If your car is like most, the cooling fan is mounted to its drive pulley via a clutch. Clutch fans operate at different speeds under different conditions to help reduce drain on the engine and to save fuel. When the engine is hot, the clutch fan runs nearly as fast as the engine. When the engine is cold, the fan runs much more slowly.
The fan clutch operation is regulated by a valve that is opened and closed by a thermostatic spring. The valve controls the flow of a viscous silicone fluid between chambers in the clutch assembly. When the engine is cold, the clutch is essentially disengaged, which is why the fan runs at its slowest compared to the engine's speed. As the engine warms up, the air flowing to the fan assembly becomes hotter. The hotter air causes the thermostatic spring to unwind and open the valve. Silicone fluid from the reservoir chamber flows into the main chamber, engaging the clutch, and the fan spins faster (though it's still slightly slower than the engine.

Hope this helps!

It's not easy.
It took me four hours to change the three plugs on the rear bank, but it can be done.
The way I did it, I put the aztec up on ramps, slid underneath and followed the spark plug wires down to the plugs. I ended up working mostly by feel instead of sight.
With a lot of patience, an assortment of extensions and a swivel joint, the plugs can be changed.

An extra elbow in your right arm, and a large assortment of four letter words would also be handy to have.
Good luck!

SOURCE: looking for the thermostat location

This should be a 3400 SFI engine. the T-stat is in a tricky location. Your top radiator hose is connected to an aluminum pipe. thats the T-stat housing. the T-stat is in there where it connectes to the lower intake there are 1 bolt1 that you need to remove.and the lower on just needs to be lose. the lower hole is sloted. you have to remove the exhaust crossover shield and coolant bypass tube if you have one. its going to be a very tight fit if you leave the crossover pipe on. you can remove it. then its 1 2 3. this is alittle longer than most T-stats i would say about 1.5 hours assuming no studs on your crossover break. just be carefully to apply even pressure when removing those bolts on the exhaust pipe.

Good luck,
michael
