Detailed Description

Rein CHR0066R is an OE quality radiator coolant hose designed for European vehicles that need a precise replacement at the lower radiator-to-pipe location. It measures 21.5 inches centerline length and uses EPDM hose material with a maximum working pressure of 50 psi. The hose end sizes are engineered to match the original BMW cooling system connection points for a clean, secure installation.
