Rein CHE0481 Engine Coolant Pipe - Water Pump To Valley Pan

OE Water Hose for BMW and Rolls-Royce

Rein CHE0481 is an OE-quality engine coolant pipe designed as a direct replacement for the water hose running from the water pump to the valley pan. Built for European applications, it matches the original hose shape and branch design for a precise service fit on BMW and Rolls-Royce cooling systems.

For BMW 745i, 745Li, 750i, 750Li, 760i, 760Li, 545i, 645Ci, 550i, 650i, X5, M760i xDrive, and M760Li xDrive, as well as Rolls-Royce Ghost, Phantom, Cullinan, Dawn, and Wraith, CHE0481 supports a direct OE-style repair without hose modification.

• Direct replacement for the OE coolant hose assembly
• Reduces installation time during cooling system service
• No cutting, refitting, or adjusting required
• Thermoplastic quick-connect fittings match OE design
• EPDM hose construction resists heat, salt, road debris, oil, and other contaminants
• Helps avoid leaks caused by reusing old quick connectors and O-rings

Detailed Product Overview

Rein CHE0481 is a black EPDM coolant hose engineered for the water pump to valley pan route on select BMW and Rolls-Royce vehicles. The hose follows OE dimensions, including branch shape and connector style, so it installs like the original part and maintains the factory cooling-system layout. This makes it a practical choice for BMW X5 cooling hose replacement, BMW 760Li coolant pipe service, and Rolls-Royce Phantom water hose repair where exact routing matters. This part cross-references Genuine 11511439976 for the same application.

Common Problems This Part Can Address

• Coolant leaks at the water pump to valley pan hose connection
• Cracked or aged EPDM hose material
• Damaged quick-connect fittings or worn O-rings
• Poor fit from repaired or modified hoses
• Extended service time caused by non-OE hose routing

Installation Notes and Tips

Inspect the mating connectors, sealing surfaces, and adjacent cooling components before installation. Replace any worn seals or damaged connectors as needed, and verify that the hose is routed exactly as the OE part was routed. Confirm application by year, make, model, and position before service.
