  • Overheating caused by restricted coolant flow
  • Service replacement for aging BMW cooling system hoses

Installation Notes and Tips

Confirm the hose routing before installation and compare the existing hose to the listed 550 mm length and 55 mm width. Inspect adjoining cooling system components, including hose necks, clamps, and the radiator and expansion tank ports, for wear or damage before reassembly. For BMW Z3 applications, verify the build date note shown in the fitment data, especially the 1998-1999 listing with the To 09/1998 note.
