Help. The coolant overflown bottle om my T-Bird Keeps filling up and the car starts to run hot. I beleive that the cooling fan is not coming on at the proper heat range. What sensor should I replace. The Engine Coolant Temperature sensor or the Coolant temperature sending Unit. I beleive that the sending unit controls the temperature guage on the dash but do not know what signals the fan to come on. Any help would be apperciated.
Thanks
