How to remove and install the Cooling Hose and expansion tank?

If a faulty hose is found, drain the cooling system and disconnect the hose by prying up the retaining clip or loosening the hose clamps. Avoid disconnecting while the system is hot. Some models may have twist-on clamps that need to be rotated counterclockwise. Be careful when removing hoses from the radiator, and if a hose is hard to remove, rotate the ends or slit it with a knife. To install a hose, push it over the fitting until the clip locks it. Slide clips onto hoses with traditional clips before positioning. Soften stiff hoses with soapy or hot water if needed. Refill the system and check for leaks. To remove the coolant reservoir, remove the air intake duct, disconnect the hoses, remove the bolts, unclip the reservoir, and lift it. Disconnect the coolant level switch connector and remaining hose before removing the reservoir. Installation is the reverse of removal. Refill the cooling system.

BMW 328i Coolant Reservoir

Coolant Reservoir in BMW 328i is a major aspect of its cooling system, being a stage that helps contain or hold a surplus of coolant fluid if there is an instance of overheating, preventing the engine from seizing up. There are two types of Coolant Reservoirs used in these vehicles: increased and non-increased and are characterized by the material of their cap. The main function of this component is to provide the coolant from coming out of the system and maintain the engine temperature level to be safe. Nonetheless, because of heat and chemical exposure, such plastic construction of reservoirs is vulnerable to crack and failures which requires frequent assessment and replacement when developing cracks or leakage is observed.
