What are the reasons for high engine temperature in BMW?

BMW engine overheating is caused by insufficient coolant, and the owner can simply add coolant. The full name of coolant is antifreeze coolant, which means a coolant with antifreeze function. Antifreeze can prevent the coolant from freezing and cracking the radiator or damaging the engine cylinder block during parking in cold seasons. BMW is a German automobile brand, belonging to the BMW Group, which has four model series: i, X, Z, and pure numbers, as well as series such as 1, 2, and 3, and the M series based on improvements to each series. Taking the BMW 1 Series as an example: the BMW 1 Series is a compact car with a length, width, and height of 4462mm, 1803mm, and 1446mm respectively, a wheelbase of 2670mm, and a body type of a 4-door 5-seater sedan.
I've encountered this issue before, BMW engine overheating is mainly due to an inefficient cooling system. It could be that the antifreeze level is too low or it hasn't been changed for a long time and has deteriorated. A faulty water pump can also prevent the coolant from circulating. Additionally, if the radiator is clogged with dust or insects, heat can't dissipate, and it's even worse if the electric fan isn't working. Another possibility is a stuck thermostat that won't open for the main coolant cycle, or carbon buildup in the engine affecting heat dissipation. If you see the coolant temperature warning light on the dashboard, immediately turn the heater to the maximum setting to help cool it down, and stop in a safe place without turning off the engine to let it idle and dissipate heat. You can check for any signs of leakage in the antifreeze reservoir and whether the fan is spinning, but for actual repairs, you'll need to take it to a professional shop for a computer diagnosis. Never force the car to keep running, as high temperatures can damage the engine in minutes.
