Detailed Description

Febi 37128 is a radiator coolant hose engineered for BMW models that use a 235 mm hose running from the engine to the heater valve. EPDM rubber is commonly used in cooling system hoses because it is suited to heat and coolant exposure in normal engine operation. This hose is listed for BMW 320i, 323i, 323is, 325i, 325is, 328i, and 328is applications across the model years shown below. If you are replacing a worn BMW radiator coolant hose or servicing a heater circuit leak, Febi 37128 provides the correct length and routing for the specified vehicles.

This part cross-references BMW OE numbers 64 21 1 387 423 and 64 21 1 394 293 for the same application.
