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!
Testimonial: The best company I have ever dealt with
LRS hands down is doing everything right. Every experience I have ever had with them shows just what an amazing company they are. There is a reason I come back time after time, instead of going to those "other" mustang aftermarket websites. Customer service is the name of their game, and they are winning. It does not matter whether you call, email, forum PM, or go to the actual store, they are always incredibly helpful and enthusiastic. (Getting to see the Cobra R in their showroom was awesome). I'm proud to have the LRS windshield banner on my car, because I know they will always have my back.
