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.
Duralast is ok. Does not have to be OEM. It will work just as good
I've used Autozone's Duralast thermostats without issue on my old Integra.
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.
I always use Premium Thermostats, which are billed to fail open. Gates or Stant are my favorite brands.
i personally run a 90c/195f one, the GATES 33209. it gets cold here in WI and it will hold 192f on the highway with the heat at speed 1
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.
Duralast thermostat? They are a piece of shit!
I warranty my shitty duralast thermostat (I hate duralast but when I gotta get to work the next day it works in a pinch it works) now after a 5 am swap I’m good to go
