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
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.
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.
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.
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
I’ve changed mine once already recently (it was a duralast thermostat because I’m stupid, that might be the current issue) and it’s still acting similar and trending towards overheating at 60+ mph even with the radiator fans on high. The radiator in lines are frigid after it’s been running at mid/high temps and the radiator out lines are hot
