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

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

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

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

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
