I’ve had so many replacements fail in all my Nissans over the years that I just get an oem one from a dealer. Never had an oem one shit out yet.
I replaced mine with this one and it has been running perfectly for 6+ months after my original one stuck open. I would not buy anything other than Mopar.
I had the same issue and throwing a bad thermostat error code. I had the thermostat replaced and it kept happening. He said the thermostats out there are crap and they’ve had to change some 3 times. He did recommend getting a Mopar thermostat if I could. It was replaced and I’ve had no issues.
The OE version is the only one that works. Knock off t-stats will generally last a few weeks to a few months. The OE thermostat has been updated, pops at 203 degrees and lasts much longer than anything else. An OE thermostat seems to fail open. Whereas the knock-offs fail shut.
Since going with the OEM thermostat, my temp gauge has stayed pinned just below the middle of the gauge, even towing campers and heavy loads on hot days.
Only an OEM Thermostat fixed it.
Gave up and bought the genuine Mopar stat, haven't had issues since.
Finally got around to replacing the thermostat on my 2000 XJ. Temp rarely hit 210 unless I was idling for a while so I suspected a bad thermostat. Sure enough it was stuck in the open position. I was able to find an OEM one part # 5202 8186AC. 195 degree with a weephole. Noticeable difference in performance and it’s nice to have heat again.
Yep, these are a known bitch to bleed out the air, as well as aftermarket thermostat's not working well after replacement. I have seen some go thru a few to get one that works.
I recently changed my thermostat due to my temp gauge occasionally dancing. The old thermostat appears to be bypassed as theres no actual thermostat in the housing. After putting on a new nissan one and oem gasket i bled the system with a overflow funnel for about 40 minutes until i stopped seeing bubble. Also using peak 50/50. Afterwards my overheating problem has gotten worse i overheat in about 10 minutes. I tried bleeding again and same results.
