Frequency and mode of replacement of BMW 3 Series coolant: First, open the liquid storage cover (note that the radiator cover should be sealed tightly at this time), and unscrew the drain switch of the cylinder block and radiator, which should be carried out when the engine is heating at low speed. Connect the water pipe, slowly add the coolant from the upper water tank, watch it while adding it, add it to the highest line to start the car, add the coolant later, and finally cover it. If the coolant level is lower than the standard line, add a mixture of 50: 50 demineralized water and antifreeze that meets the specifications of this vehicle. In order to protect your car in extremely cold weather, please use the coolant with the specification of -45 degrees Celsius.
