I have a 2003 5.4liter f-150 and i need to know where the coolant temp sensor is if any one could tell me i would be very happy..thanks

 

You don't have one dude .. Here's mine - it's right behind the alternator , but they discontinued those with the plastic manifolds, your cylinder head temp sensor handles it now and sends readings to the PCM which makes sure your within parameters ..

They use to be here tho -
