****GET THAT CHECKED OUT ASAP!!!!!!! The fans should be working when the temp gets above the mid mark, If the previous owner overheated the car the heads may be warped which will cause the car to overheat all the time. Mind you this is a very costly repair. With warped heads the car seems to run fine but it is not. Also have the cooling system checked , Incorrect level or air in system will cause the car to run hot.
