Where to Add Coolant for BMW?
2 Answers
BMW adds coolant at the far right side of the engine compartment. Do not open the cooling system when the engine is running at high temperatures, as it may cause scalding due to coolant spraying out. Only use the appropriate coolant, otherwise it may damage the engine. Here are the precautions for adding coolant: 1. Coolant consists of water and coolant additives. Not all additives on the market are suitable for your car. After topping up, make sure to close the antifreeze cap properly. The correct coolant level is crucial for the trouble-free operation of the cooling system. Therefore, the coolant level should be checked regularly. 2. After adding coolant, start the engine and turn on the air conditioning system to check and confirm that the radiator cooling fan is working, in order to inspect for any coolant leaks in the radiator or hoses. When the air conditioning system is turned on immediately after a cold start, the fan should operate. Confirm the fan is running by checking the sound and airflow of the fan.
I've been driving a BMW for several years and often top up the coolant myself. Just look for the plastic tank with the coolant symbol under the hood - it's usually a white translucent container with a wavy line pattern on the cap. Always wait until the engine cools completely before opening the cap, as opening it while hot can release scalding steam. Use only BMW-specific coolant, and never mix different colors - blue and green coolants can cause chemical reactions when mixed. Maintain the fluid level between the MIN and MAX marks on the tank. My routine is to fill it halfway when cold, then top up to the middle after starting the engine when the level drops slightly. If you notice the coolant depleting unusually fast, there might be a leak in the pipes or radiator - that's when you should immediately visit a repair shop.
