Can you find the location?
Here is what the switch looks like:
Some people pull them out with channel-lock pliers, you risk "egging" it and messing up its operation.
A regular socket will not fit it.
This is what you should use, it fits perfectly. Some of these are "stepped", the step will fit other sensors with the same design but have a different diameter. (useful on other repairs)
The particular brand of sensor (first link) already has sealant on its threads.
No need to drain the oil, you may lose a little bit of oil (insignificant) when you take the old one out. (just so you might stick a rag under it to keep the driveway clean)
Start the new one in, insure it goes easy and is not cross threaded.
Tighten it good and snug. Do not get down on it with all your might.
Crank it up, get to operating temperature, look for drips or a leak, if it does, go a bit tighter.
easier to snug more if needed, than to get a broken sensor out of the engine.
This like changing the spark plug in your lawn mower/ weed eater!
Hook the wire back on it.
Stick you with a fork, you are done!
Return with good news!
