Silicone coolant flange hose for N55 engine in M235i, 335i, 435i. Flange sold separately.
This part is listed by BMW as BMW part number 11537598234 (11 53 7 598 234) and is described as the Engine-to-Thermostat hose for F22 M235i, F30 335i, F32 435i, and 2016-2018 F87 M2 (N55). This is the hose that exits the front of the engine and returns coolant to the thermostat. It's very common for a leak to develop at the plastic flange at the engine and cause a coolant leak (aka Mickey Mouse hose). This hose is made from stronger temp-resistance multi-layered silicone. The silicone is an extra measure of protection from high engine bay heat and other chemicals.
OEM hose clamps included.
This hose does not come with the upper flange. Order an aluminum flange separately (click here) or use this hose with your own favorite flange.
