Buy a new o-ring for the temperature sensor or it will leak.

The only thing I didn't like was that the o-ring is slightly larger than the factory ring. So plan on finding an o-ring that works, or buy a new temperature sensor that comes with an o-ring and metal clip. It will leak if you don't. That aside, it looks like they've improved their castings and they've even cast a factory part number into the case.
