The coolant temperature sending unit indicates the engine temperature to the temperature gauge.
The coolant temperature gauge sending unit on your Mustang is an important part of knowing what is going on in your engine bay. If yours is out, you are playing a dangerous guessing game! Don't risk your engine on such an inexpensive part. Replace it right with this quality piece from Motorcraft and rest easy knowing that your engine isn't overheating!
