Radiator Replacement Instructions

Model: BMW Serie 5 E61, E60 - Years 2003-2010
Part: Radiator

Clogs or coolant leaks from the radiator are generally caused by rust formation in the system, which occurs especially if only water is used in the cooling system. To prevent this issue, it is recommended to use the appropriate coolant (various types are available commercially, either concentrated or ready to use).
In any case, if you need to replace the radiator, perform the operation with the engine cold, drain the fluid, remove the electric fan, disconnect the hoses, remove the grille cover, and extract the radiator. Then proceed with the installation of the new radiator, reassemble everything, and fill the system with coolant, ensuring no air has formed.
