did you touch the face of the radiator? if you are overheating and the radiator is still cool or only luke warm, you have a t-stat issue or a clogged radiator, but since the radiator has about 100 paths up and down, its usually a small section that is clogged and not flowing.
you cannot remove the t-stat, but you can put a small electric motor gear (you know the ones on toy electric motors) on the shaft of the t-stat to force it full open and re-install it.
you only need to burp the system by squeezing the two main radiator hoses when the engine is cold. (doesnt work when things are hot, so dont try)
if the radiator is hot, then its doing its job, and if you are still overheating, it might be a headgasket, but that usually manifests itself by pushing water out the overflow and then you overhead due to lack of water.

Yep you have to run a thermostat the wizard that had my car before me pulled mine and it would severely over heat. There was also a copper insert in the radiator that was turned the wrong way restricting flow.

let me know if you need more details on how to "rig" the t-stat.
Basically, you push the part that opens so far that the guiding shaft comes out of the center guide Then,you put a spacer in there (toy motor brass gear). this forces the t-stat open, but when you install it, the spring loaded part in the rear is uneffected, so it is free to seal against the main internal rear seal surface.

Finally got done with the problem...THANKS GUYS ! It must've been the thermostat along with a faulty fan cluch. I didnt realize that you cant remove the thermostat on a 928 ! I put back a new thermostat along with the electric fan and it ran like a charm. I got a 75 C thermostat along with 75 C radiator switch. It stays jsut above the first marker.

The brembo calipers have two plates, one at either end. The aluminum corrodes underneath the plates lifting them. This squeezes the brake pad from either side preventing it from moving freely. If when changing pads you notice you can't get them in and out easily then you have plate lift.
The dirty fix is to grind the edges of the pads. Proper fix is remove the plates clean up the caliper then replace them.
