replaced the thermostat with a factory Nissan OEM thermostat. Completely fixed the problem..
I had the same exact car with same exact problem. I changed the thermostat once and it fixed it for about a year. The issue came back and I changed again and it fixed it again... So I'd say get an OEM one if you can.
our 2009 CRV was taking a long time to get to operating temperature and then fluctuating a lot while driving. a new thermostat fixed it.
Don\u2019t listen to these people I have an 08 ex Sam problem replaced thermostat 2 weeks ago in 15 minutes problem is gone
yes the part was OEM from nissan
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.
After getting a P0128 code and replacing the Tstat with an OEM equivalent from a parts house and my code coming back and then actually buying the OEM straight from the dealer fixing my code, I’m hesitant on what I should really put in my car since it seems to be sensitive to parts as well. I remember buying Tstats from AutoZone and never being a problem before.
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.
Car takes forever to warm up and seems to always be running rich, so I'm guessing either the thermostat or ECT, or both, is/are bad.
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.
