Oh I know it’s overheating because fan goes to full speed and then some time shortly later yellow and later red overheat warning. But still it doesn’t do that with full blast 84’ even if I drive around like a race car driver (for testing purposes) . Will keep updating but in case you’ve had before lmk. Radiator and hoses temp by touch… well to me didn’t seem like they have issues.. bmw adventures in the garage , right?
