replaced the thermostat with a factory Nissan OEM thermostat. Completely fixed the problem..
I only use Gates now after some cheap ones failed but didn't leak. Gates are very good. I have not had to replace one.
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.
I installed a Gates 33009S 195 degree after my Hughes install and haven’t had issues.
The brand new thermostat wasn’t opening all the way. One new Gates thermostat fixed the issue.
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.
I installed a Gates one a couple months back and it worked well for a little while; engine got up to operating temp fairly quickly and stayed there, but now it’s running really cold no matter how long or how hard I drive it. Think it’s stuck open.
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.
