The Rein heater hose (part number CHH0232) is designed as a direct OE replacement for specific BMW vehicles. It meticulously replicates the original equipment manufacturer's hose in size, shape, and features, including the thermoplastic quick-connect fittings, ensuring a perfect fit and function. This design allows for a reduced installation time, as no cutting, refitting, or adjusting of the hose is necessary. By using a new, correctly designed hose, it helps prevent leaks and potential comebacks associated with reusing old connectors and o-rings. Constructed with durability in mind, this Rein heater hose is resistant to common automotive environmental factors such as heat, salt, road debris, and oil. This resilience contributes to its longevity and reliable performance in the demanding conditions of the engine bay. Rein Automotive specializes in OE-quality replacement parts for European import applications, aiming to provide parts that fit and function exactly as the original manufacturer intended. This specific heater hose is intended for V8-powered E39 models, including the 540i and M5, from model years 1997-2003.
