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
Your thermostat is probably stuck open. Replace it with an OEM Motorcraft version, not aftermarket.
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.
The Motorcraft thermostat sounds promising though, never have an issue with genuine ford parts.
I used a motorcraft RT-1139 thermostat. Comes with a jiggle valve to help bleed air already installed and cost me 8 bucks. You won’t find any place that says they fit other than some forum posts but they do indeed work, I installed one on my MJ with the only issue being me not refilling the radiator after dumping all the coolant.
I replaced the thermostat from a non-OEM to Motorcraft about a month ago, and the only difference has been the speed at which the dial moves from higher temps to its normal positon.
I bought a Motorcraft thermostat from the Ford dealer for my Crown Vic and it ran about 20 degrees cold.
I have a 2015 sedan and I’ve got 192,000 km and owned it since brand new and I’ve had that happen and changed the thermostat twice, just make sure you get OEM Honda thermostat and coolant as it takes a certain type. Make sure you
Burp the cooling system of all air and make sure you add enough coolant to the radiator and overflow, it’s fairly common for the thermostats to fail
