BMW Radiator Hose Upper - Rein 17127514404

Carries coolant from radiator to thermostat

Your Z4's upper radiator hose carries cool coolant from the radiator back to the engine via the thermostat. As with all rubber hoses this upper radiator hose can swell and crack. If you notice unusual bulging we recommend replacing immediately before you suffer a catastrophic cooling system failure. While you're at it we also recommend replacing the lower radiator hose at the same time for best system service life.
