OE Quality Heater Hose for BMW Applications

The Rein CHH0507 is an OE-quality heater hose built as a direct replacement for European vehicle cooling systems. It is shaped to match the original hose assembly, including the branch geometry and thermoplastic quick-connect fittings used on the factory part.

For BMW owners searching for a direct-fit heater hose for oil cooler to pipe service, this Rein hose supports a clean replacement on select 2006-2011 BMW Z4, 2008-2010 BMW 528i, and other listed applications. The Rein CHH0507 is made from EPDM and finished in black for a factory-style repair.

Key Features

• Direct replacement for OE heater hose assemblies
• Application-specific fitment reduces installation time

Detailed Description

Rein CHH0507 is a complete OE-quality heater hose designed for European vehicles that require an exact replacement rather than a universal hose repair. The hose measures 28.25 inches centerline length and uses factory-style end dimensions to match the original cooling system connection points. Its single-hose design and direct-fit construction help maintain proper routing and sealing in the engine bay.

This part cross-references Genuine 11537519494 for the same application. It is a practical choice for BMW cooling system service where the original hose has aged, hardened, or begun to seep at the connectors. Search terms such as BMW Z4 oil cooler to pipe heater hose, BMW 528i oil cooler to pipe hose, and Rein CHH0507 OE quality heater hose all point to this direct replacement.

Common Problems This Hose Can Address

• Coolant seepage at worn quick-connect fittings
• Cracked or hardened hose material from heat cycling
• Leaks caused by reusing old O-rings or connectors
• Poor fit from trimmed or universal hose repairs
• Routing issues after an incorrect replacement hose is installed

Installation Notes and Tips

Verify the vehicle’s original hose routing and connector style before installation. Because this is an application-specific replacement, it is designed to install without cutting or refitting the hose. Inspect mating surfaces, replace damaged seals as needed, and confirm the connection points are clean before securing the hose.
