How do I properly maintain the cooling system on my BMW 7 Series?

I noticed that my BMW 7 Series' engine has been running hotter than usual. What steps should I take to ensure that the cooling system is properly maintained and avoid any potential damage?

First, make sure to check the coolant levels regularly and top them off if necessary. Also, keep an eye on the temperature gauge and immediately stop driving if it reaches the red zone. In addition, I recommend getting the cooling system flushed every 2-3 years to prevent any build-up. And finally, don't forget to replace the radiator cap and thermostat every 4-5 years.
