Detailed Description

Rein CHE0587 is a complete European direct-fit hose for the thermostat-to-water-pump coolant circuit. It is built to match the original hose assembly dimensions, including the branch shape and thermoplastic quick-connect details, so it installs like the OE part on BMW 320i, BMW 328i, BMW 428i, and BMW 528i models across the listed years. This makes CHE0587 a practical choice when replacing a worn, brittle, or leaking engine coolant hose in the cooling system.

This part cross-references BMW OE numbers 11534615722 and 11537603511 for the same application.
