4.6L engine
Help, can someone tell me where the EEC coolant temp sensor is located on my Ford F-150 4.6L engine. One dealer told me that it didn't have one. Another dealer told me it did, sold it to me but I can't find it on my motor. Thanks,
Mark

Hi and welcome to the forum 
Your engine doesn't use a coolant temperature sensor. It uses a CHT(Cylinder Head Temperature sensor. It screws into the driver's side head. It doesn't actually go into the coolant. To get at it you have to remove the intake manifold
What sort of problem are you having?

My '98 has 2 tempurature senders in the front crossover of the intake manifold. 1 is used for the temp gauge on the dash. I assumed the 2nd one was used by the ECU. I also have a cylinder head sensor on the drivers head.

Dave, I see several advantages of CHTs. Mainly they don't give false readings with air bubbles, exhaust bubbles, or low coolant and they aren't dependent on flow rate. Are there any disadvantages? Is there still a separate sender for the instrument cluster?

Ok, racerguy is right. It's a 2000 f-150. my problem was my service engine soon light came on. Had a po125 code set. which is insuffcient engine coolant temp. I bought a sensor, which I shouldn't had done yet. Finally found it under the intake manifold. But the connector on my harness was slightly different than for the new sensor. Anyway, I went ahead and changed the thermostat and o-ring. Erased the code, and it hasn't come back yet. I think the thermostat was the culprit. Thanks Guys
