Have you had the cooling system flushed ?

The cooling system probably needs to be bled out from air pockets. Bet it was not done when refilling the cooling system. Otherwise a clogged radiator or blown or cracked head, or head gasket.

As noted by other people it could be several things. (1) is it actually overheating? What are the symptoms? Is it just the temp gage showing hot or is the engine actually getting hot and pushing coolant back into the reservoir ? (2) If the engine is not actually getting overheated, then it is probably a bad sending unit. (3) are the fans working? On the Reatta the one on the engine side comes on first as the temp goes up, then the one on the front of the radiator comes on...both at half speed...then if the temp get to around 230 both fans should go to high speed. There are several relays involved (they are in the underhood relay center located in front of the air cleaner) let us know what you find.
