BMW X5 Engine Oil at 98°C, What is the Coolant Temperature?

[KaiDella]

BMW X5 engine oil at 98°C, the coolant temperature should be 90°C. Hazards of Abnormal Engine Coolant Temperature: When the engine coolant temperature is too low, the combustion of gases inside the engine becomes incomplete, and it also affects the lubrication effect of the antifreeze. Of course, the vehicle's tailpipe emissions will exceed standards. When the temperature is too high, it can easily cause boiling, leading to excessive engine temperature, which can damage the engine. Standard Settings for Engine Coolant Temperature: The normal coolant temperature for BMW engines ranges between 80°C and 120°C. The engine control unit can adjust the engine temperature according to driving conditions. It can achieve four different temperature adjustment ranges: 112°C for economy mode, 105°C for normal mode, 95°C for sport mode, and 80°C for maximum power mode.
