Pros: completely fixed problem

The gasket looks fine. Normal procedure would be to buy a new one from BMW. always go OEM with the thermostat, there's a lot of shit knockoffs.
Cons: shit knockoffs
yes the part was OEM from nissan

I recently moved on from a 2016 X3 35i (N55) with a little over 100k miles on it. The only things to break on it were the thermostat and a control board for one of the headlight modules. When I replaced the thermostat I did the water pump as a precaution.
Pros: only consumables
Cons: thermostat broke
Vehicle:
BMW X3
Mileage: 160934 km
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.
Pros: OEM reliable, no failures
Vehicle:
Nissan
My 535i with the 740d thermostat sits at 90-95 during normal use, even sat stable at 95c during 40c weather in traffic. When beating on it in the mountains got it up to 99 at like 28c ambient.
Pros: stable 90-95c temps
Vehicle:
BMW
Notice the radiator is leaking. Replace that. Car still not happy, cooling fans on full blast. Codes point to a thermostat, but the radiator hoses get warm. In my pea brain thermostats don't normally just sometimes go bad, they're typically either all broke or not broke. Ordered a thermostat from Trumplandia anyways.
Cons: expensive, complex design
Vehicle:
BMW
I bought from FCP euro one of the OE water thermostat and water pump. The thermostat sticks open since new so I get check engine light on my M54 engine.
Cons: thermostat sticks 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.
Cons: overheating problem worse
Vehicle:
Nissan
I have had brand new bmw thermostats not work and cause my car to get hot on the highway.
Cons: thermostat not working, car overheating
Vehicle:
BMW
