## Questions & Answers

**Q: Does it fit in a Jeep liberty 2004 upstream and downstream?**
A: I have this products istaled in my 2012 Jeep liberty but you need to purchase the right part for your car.

**Q: Is this sensor also for downstream on driver side? 2017 Ram 1500**
A: Hello:
No, 350-34039 does not fit the Upstream and Downstream positions.
2017 Ram 1500 has 2 gasoline/flex engines that have O2 sensors 3.6L & 5.7L.
The 3.6L takes 350-34213 in both Upstream and Downstream positions.
The 5.7L takes either 350-34039 or 350-34213 in the Upstream position and either 350-34039, 350-34213, or 350-34592 in the Downstream positions depending on transmission type and 2WD or 4WD.

Product had “already antiseez” on threads which the installed was a bit challenging. Works like it should. fit perfectly. You will have to apply pressure with your fingers to tighten the O2 Sensor. I recommend to use the special made socket for it as well.
