BMW 5 Series coolant filling has a method. Method: Open the hood, and there is a black reservoir on the left side of the engine. Open the reservoir cap to add coolant. Coolant function: The full name of coolant is antifreeze coolant, which has antifreeze function. Correct use of coolant can not only protect the engine cooling system and improve heat dissipation, but also improve engine efficiency and extend service life. Replacement cycle: The coolant for the BMW 5 Series is generally replaced once a year, or for vehicles with shorter running times, it can be replaced every two years or every 30,000 kilometers.
Having driven a BMW 5 Series for many years, I know that adding coolant is not something to take lightly. First, ensure the engine is completely cool, otherwise the steam can scald your hands, which is very dangerous. The expansion tank is usually located in the front engine compartment, with a BMW logo or blue marking on the cap. Check the fluid level when the engine is cold—only proceed if it's below the 'min' line. Use genuine BMW blue antifreeze coolant, and never mix it with other brands to avoid clogging the system. Pour it slowly up to the 'max' line; pouring too quickly can cause overflow. Then, start the engine for a few minutes to let air bubbles escape through the vent. After completing the process, tighten the cap securely and check the hoses for any leaks. Doing this regularly can prevent engine overheating. I recommend checking the coolant level every six months to keep it stable and avoid breakdowns during long drives.
