Where does the knock sensor mount? I know on the new 3.0Ls I need to retap the threads to fit the 2.5L sensor, but I don't know which hole it goes into. I don't see anything in my Haynes about it, I'll hae to look in my Ford CD, but if anyone could help me out it would be greatly appreciated.

The knock sensor is on the side of the engine closest to the firewall. It's just forward of the back of the block.

If you have one.
My 99' 2.5L did/does NOT have one.

Both 00's I have installed headers on had them however.

Now that's wierd ... my 98 SVT had/'01 3L has one. I know b/c the sensor and the 3.0 block didn't match (at first).

I've never seen a contique engine without one. Are you sure you weren't just confused becuase of the two different styles? The old style was a large plug type sensor that bolted directly to the plug and the electrical hooked to it. The new style is a round black washer type sensor that has a bolt hole through it and has the wiring attached to it.

Well considering I built my 3.0L with all my 2.5L components and wiring.......

My 3.0L did not have one either. (Early 2000 Block)

It's not there.
Trust me

The block alone does not come with one installed on it - kinda like thinking the alternator comes with the block - not so.... It is only with the engine assy. If the block was used, I am sure the bone yard took it off. If the block was new, again, it would not be pia. These engines require this part. I would be a bit concerned running without it.......

ESPECIALLY if running a high compression hybrid. It's not a panacea for bad timing, but it will be quite useful if you need it and if it works. Like say getting the wrong grade of gas from some idiot in NJ.

It was a complete engine assembly, all sensors, all harnesses, etc. (and it did come with an alternator! )

Since my 2.5L harness does not have a provision for this, its not like I can add it.....

I wonder if the SSD3 PCM code even supports a knock sensor?

Pics of the 2.5L moments after it came out of my Cougar.



Like I have said, I've worked on 2.5L's that have had a knock sensor, so I know where it should be located. Once again, I have a freak!
