13 BMW 520li coolant has two POTS.
BMW 520li is a high-performance car, in order to ensure the normal operation of the engine and heat dissipation, it uses a double pot cooling system. This means that the coolant is divided into two separate POTS, one for cooling the engine and one for cooling the turbocharger. This design allows for better temperature control, improved engine efficiency and life, while ensuring the stability and reliability of the car under high load operation. It is worth extending that proper maintenance of the cooling system is essential for the proper operation of the car. Regularly check the level and quality of the coolant, replace the aging coolant in time, clean the cooling system, and ensure the circulation of the coolant, which can effectively extend the service life of the car and improve the safety of driving.
The 13 BMW 520li models have a coolant capacity of 8.5 liters, which normally requires the use of two coolant POTS to complete the coolant filling. Each coolant pot has a capacity of about 4 liters, so using two POTS can meet the needs of the entire cooling system. When filling the coolant, it is necessary to ensure that the cooling system is completely emptied and the correct coolant type is used to ensure the normal operation of the engine and the heat dissipation effect. Please refer to the vehicle's owner's manual or consult a professional technician for accurate operating instructions before filling the coolant.
