Thermostat MOPAR or OEM Nissan

Replace stat with a Mopar 195f unit for optimal results.

I had this exact issue with 3 aftermarket thermostats that were opening too early. Bought one from Nissan and my temps went back to normal

OEM Nissan, but slightly more conservative with cooling.

Replacing the Thermostat with a OEM part has solved the issue (with coolant flush) from a dealership.

I replaced the one in my sisters V8 WJ with Mopar and it was made in Israel and very high quality.

After reinstalling an OEM thermostat, I am very happy to say my high temp issues have been solved!

We had to replace thermostat from Nissan group Infinity. So far no problem right now

Just make sure you buy a genuine Nissan thermostat. I don't know what it is about these cars, but they do NOT like aftermarket thermostats. Just spend the extra ten bucks on a Nissan part.

Oil cooler and radiator. I changed the thermostat when my radiator went. I would recommend using a mopar thermostat as I had two aftermarket fail on me

I had a very similar issue. Radiator and Thermostat replaced after accident. 2014 WK2 3.6 V6 was overheating when I drove up the mountains in Colorado. The problem was the mechanic put a Napa thermostat in, then replaced with another napa thermostat. I bought a MOPAR thermostat and swapped it myself.
