Coolant Temp Sender 1998 5.4L 2WD ( my version of reality )

[Mark Burns]

So, I replaced the coolant SENDER unit with TS-380 from my local auto parts store and the gauge now performs correctly. So, for all of you back yard mechanics it pays to do a little research and find someone that actually knows what the hell we are trying to fix instead of selling us dumby's the wrong part over and over again.
