Rein CHE0691 Engine Coolant Hose

OE Coolant Hose for BMW Applications

Rein CHE0691 is an OE-quality engine coolant hose built for BMW cooling system repairs that call for the original hose shape, branch layout, and thermoplastic quick-connect fittings. It is a direct replacement for the factory hose assembly, helping restore proper coolant routing on BMW X5, X6, 550i, 650i, and 750i models.

With application-specific fitment and a branched EPDM construction, this Rein coolant hose is made for clean replacement work on European vehicles where the original connector design matters. The CHE0691 part number is a practical choice when replacing a worn BMW engine coolant hose with plastic connector hardware already integrated into the assembly.

Detailed Description

Rein CHE0691 is engineered as a replacement engine coolant hose for BMW vehicles that use a plastic connector style hose assembly. The hose is shaped to match the OE routing and branch layout, which helps maintain proper coolant flow and simplifies service on the BMW X5, BMW X6, BMW 550i, BMW 650i, and BMW 750i platforms. Because the assembly mirrors the original design, it supports a cleaner repair than adapting a universal hose.

This Rein coolant hose is built from EPDM and finished in black for a factory-style appearance. The OE-quality construction includes thermoplastic quick-connect fittings and a branched layout with two branches, making the CHE0691 a direct-fit solution for European cooling system maintenance. This part cross-references BMW 17127619702 for the same application.

Common Repair Uses

• Replacing a cracked or leaking BMW engine coolant hose
• Restoring coolant flow after connector or branch failure
• Fixing seepage caused by worn quick-connect seals
• Addressing cooling system leaks from aged hose material
• Repairing a damaged hose assembly on BMW X5, X6, 550i, 650i, or 750i models

Installation Notes

Before installation, verify the vehicle’s hose routing and connector style against the original assembly. The direct-fit design is intended to reduce installation time and eliminate the need for cutting, refitting, or adjusting the hose. Inspect mating surfaces, seals, and surrounding cooling system components before reassembly to help prevent repeat leaks.
