Does anyone know where the coolant temp sensor unit is located on a 2006 F150 5.4L FX4? I have looked all over the engine and see several sensors but haven't been able to determine which is the temp unit. Any help you could offer would be greatly appreciated.
Remove the intake. If your able to / have small enough hands, you and fit a 3/4 inch wrench under the intakes tunnel and get it out. I changed mine before w/o removing the intake. You won't be able to get to it from under the truck.
