Rein CHE0497 Engine Coolant Hose - Water Pump To Pipe

OE Water Hose for BMW Cooling Repair

Rein CHE0497 is an OE-quality engine coolant hose for European vehicles, built as a direct replacement for the original water hose assembly. It is shaped for the water pump to pipe route used on select BMW models, helping restore proper coolant flow with a factory-style fit.

For BMW 128i, 328i, 328i xDrive, 323i, X3, 328xi, 325i, 325xi, 330i, and 330xi applications, Rein CHE0497 follows the original hose geometry and quick-connect design. The result is a cleaner repair for the BMW cooling system without reworking adjacent components.

Key Features

• Direct replacement for the OE coolant hose and hose assembly
• Application-specific fit for water pump to pipe routing
• Thermoplastic quick-connect fittings match OE-style connections
• EPDM hose construction resists heat, salt, road debris, oil, and other contaminants
• Installation hardware is provided
• Built to SAE J20R4D1 standards

Detailed Description

Rein CHE0497 is engineered to match the original hose dimensions, branch shape, and connector style used on the vehicle. This OE-style approach helps maintain proper coolant routing and simplifies replacement when the original hose has cracked, leaked, or degraded. The black EPDM construction is suited for engine bay temperatures and common underhood exposure, while the direct-fit design supports a precise repair on BMW cooling systems.

This part cross-references Genuine 11537535829 for the same application. It is a practical choice for BMW 128i and BMW 328i cooling system service, as well as other listed BMW models that use the water pump to pipe hose layout. Rein CHE0497 is a focused replacement for the original coolant hose path, not a universal hose.

What It Helps Repair

• Coolant leaks at the water pump to pipe hose connection
• Cracked or hardened original hose material
• Failed quick-connect ends or worn sealing surfaces
• Cooling system service issues caused by reused connectors and O-rings
• Fitment problems from non-OE hose shapes or incorrect routing

Installation Notes and Tips

Verify the vehicle’s hose routing and connector style before installation. Replace the failed hose rather than the full assembly when the application calls for it, and use the supplied hardware during service. Clean the mating surfaces carefully and inspect adjacent cooling components for wear, corrosion, or residue before reassembly.

Quality Assurance

Rein designs this hose as an OE-quality replacement for European vehicles, with OE-matched size, shape, and quick-connect details. It is manufactured to SAE J20R4D1 requirements for coolant hose applications.
