Is it that sensor underneath the intake man. thats bolted to the black pan? how am i supposed to mount that big thing

 

yes, yes it is. I'd imagine when you take the intake off to drop the engine in, slip it in

 

ABOUT THE TAPPING FOR THE SECOND COOLANT SENSOR.

The 4.6's came with TWO coolant sensors. If you are using the 4.6 harness, like I am, but putting in a 5.4, you have to drill and tap a second hole in the intake manifold and screw in your second coolant temp sensor.

 

Yeah i understand that. I cannot find this 2nd sensor, hell i dont even know where the first one is. All my 4.6 plugs fit into everything on my 5.4 and there are no extra plugs...that runner control valve was the last one, there are none left.

 

is it possible that it was supposed to be here but my 4.6 setup doesn't have it?

 

because im just not seeing it anywhere...And there are no empty plugs on the harness as of right now as it sits. Everything is lengthend and plugged in. The runner control valve is out of the 4.6 manifold and on the 4.6 harness attached to the 2002 5.4

 

My notes are ambiguous on this subject so I have revised them. Here is the pertinent section.

Engine harness: The IAC harness must be relocated to the rear of the throttle body elbow. The oil sender wire on the 4.6 may be too short so measure or test fit the harness to see if it must be extended. All 97-00 4.6 engines use some sort of intake manifold runner control valve. Remove it from the 4.6 and plug it into the 4.6 harness and bolt it to the engine some where out of the way. Note; you can get a tune to remove its function and eliminate it all together.
All 97-98 4.6 engines use an Engine Coolant Temp sensor (ECT) and an Engine Coolant Temp sender. By the 99 Model year the ECT was dropped in both the 4.6 and 5.4 harness as the Cylinder Head Temperature sensor (CHT) was used for the PCM to monitor coolant temps. None of the 00+ 5.4s use ECT sensor or sender. Some of the 99 5.4s still use the sender to feed info to the instrument cluster. You will have to tap the intake manifold crossover pipe to fit the sensor(s) if your 4.6 has them and the 5.4 doesn’t.

that pipe plug is where the 2nd coolant sensor is on my 4.6 manifold

 

so in reality, there is 3 coolant temp sensors. TWO on the intake manifold, and one under the head in the valley by #5. . .

 

yeah thats what i thought! so this makes me really happy that i do not have to tap anything. SWEET!

 

you wouldnt of had to anyway, you are using the 5.4 harness and PCM, right?


Dont know why your freaking out over small stuff. . . simmadowna. . . lolz

 

no. Im not. Im using all 4.6 stuff, the 5.4 stuff was way way way too different. So i will have to use the 4.6 ecu and get that tuned out and changed up. Owell its ready to go now so everythings good! BESIDES THE FACT that i cant get my torsion bars to release from the keys being that the bracket is in the way of the tcase and i dont have ANY play at all to slide the trans forward, so im pretty anrgy either way!

 

are you dropping engine in with trans aleady in the truck??? its easy

 

im taking out the old trani and putting in the newer one that came with the engine. So i have to drop the tcase with the trani and drop both shafts. Being that the torsion bar crossmember is right in the way it would be easier without it, but can do with it...So im putting at back together but since im down there i want the torsion keys set as low as they can go so do i have the bolt all the way in or almost all the way out?? (loctite it of course)

 

Never touched my torsions. no idea
