EXP119 Oil Temperature Probe Location

[OneTwoTree]

Could someone please confirm that I have the probe in the right location and it’s NOT supposed to be at the orange circle?

Bonus point if you can tell me where to safety wire it to. I’m thinking I cut the orange circle wire and wire the two in-line and through the unseen hole on the block.

Yes that is the correct location. I safetied it to the tachometer cap. If you haven’t purchased one already you will have to from ACS.

Jetmart beat me to it, but looking at Fig. 1 on p. 43-05 and Fig. 1 on p. 49-14 of the RV-14(A) KAI, that appears to be the correct location, and the OP-62 instructions don't say anything different.

Wire to the other hole on that cap (1:00) you have circled, looping CW around it to the sensor.

Definitely some inconsistencies here between Chapter 43 and Chapter 49. Chapter 43 shows your circled location, while 49 shows where you actually installed it. I suspect Chapter 43 shows the non-EXP version. I'm not sure about Chapter 49.

Another option is that if you cut the safety cable off the filter and replace it with safety wire the hole in that lug is big enough for a second safety wire to the sensor. You're going to have to replace that fancy cable with safety wire at the first filter change anyway

The chapter 43 illustration is wrong. There is no flow past the probe if installed in the end of the main gallery (the location shown in the line drawing), particularly when the vernatherm tip is extended to block the bypass hole. Might work, sort of, when the bypass is open or just partially closed, but even then it would always show the temperature of oil coming from the sump, not the oil cooler return.

There is always flow past the probe when installed in the top of filter adapter, like in Marc's photo (post 1), and it is downstream of the point where sump oil and oil cooler return mix together.

49_14.jpg (above, post 5) does not show a temperature probe location. That's the accessory case out-to-the-cooler port.

EDIT: Nope, brain fart here. That is indeed the correct probe location, lower right.

Why wouldn’t you wrap around the sender and use the holes in the filter adapter? Same location you safetied the oil filter.
Going off of memory, but think there are two holes in that location.

Here's how I safetied mine.

Thanks everyone!!! On to the next issue(s)

That looks backwards to me.

Lower right of the photo shows the temperature probe under the silicone boot.

Anyway, I think I’m clear on this. My engine is still in the unopened box in the garage. But it’s coming out soon!

You're right, brain fart by me, sorry.
