How to remove and install the Cooling Hose and expansion tank on BMW 325i?

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.
