BMW 17117537292 Radiator

To remove the radiator, start by draining the cooling system. Then, remove the air intake duct, air filter housing, and electric cooling fan and shroud. Pry out the wire clips and disconnect the radiator upper and lower coolant hoses, as well as the coolant hose from the automatic transmission fluid cooler if applicable. On E-series chassis models with an automatic transmission, remove the mounting bolt and detach the fluid cooler hoses from the radiator. On F-series chassis models, unlock the transmission oil cooler lines and disconnect the hose(s) from the radiator. Finally, remove the radiator upper mounting bolts and pull the top of the radiator rearwards and upwards to remove it. For inspection, reverse-flush the radiator if there is suspected blockage. Clean dirt and debris from the radiator fins using compressed air or a soft brush. If necessary, a radiator specialist can perform a flow test to check for internal blockage. Leaking radiators should be referred to a specialist for repair, as welding or soldering may cause damage. Inspect the radiator lower mounts for damage or deterioration and replace if needed. To install the radiator, lower it into position and secure it with retaining bolts. Ensure the fan cowl is correctly located and secure it with clips. Reconnect the hoses and check the condition of the O-ring seals in the radiator fittings, replacing any that are defective. Finally, refill the cooling system.
