Oill Level Sensor torque spec?

For the life of me, can't find it in the FSM. And went through 19 pages of search results...

It's a pipe thread, so you just snug it up. Probably want some Teflon tape on the threads, make sure it doesn't block the sensor hole. I think new ones come with a sealant paste already applied.

Ballpark around 30 ft-lbs. Since it's pipe thread it keeps getting tighter as it goes in, you can pretty much tell that it's all the way in.

The bolts on the level sensor are a pretty small diameter thread. I'd be nervous going that high and maybe breaking one off. I think ~8 lb-ft is the highest I'd go.

Since it's pipe thread it's less about torque and almost moving until it stops. The force to screw it in keeps going exponentially up as you tighten. It really just gets to the point where it's not going any further.

Regardless, to OP, don't sweat it too hard, just snug in in there and you'll be fine.

It would appear that the 3 fasteners for my oil-level sensor in my oil pan (and my spare pan) are M6's. I just might use the same value for the similar M6's that go around the perimeter of the oil pan, 100 in-lbs.

Again, it's pipe thread, so it's hard to gauge torque spec. The thread is tapered so it get increasingly tight as you tighten.

Snug up good, you'll be fine. If it's too loose, worst case is you'll have a slow seeping oil leak, if so tighten it some more.

More likely to leak if the 'O' ring is reused then from not tightening enough..

Bought the oil sensor new so it came with a fresh o-ring. Bought a spare o-ring as well.

Level sensor, not pressure sender...I was thinking of the pressure sender also.

Whoops! I'm all over the place with doing the PRESSURE SENSOR, not level sensor. Wow. My bad!

That said, torque spec for the oil LEVEL sensor on the side of the oil pan would be really low, in the inch-pounds. I would do the same spec as the oil pan bolts.
