Rein CHU0457 Engine Coolant Hose with Upgraded Metal Flange for BMW

The Rein CHU0457 is an upgraded OE-quality engine coolant hose designed specifically for BMW vehicles, featuring a pre-mounted metal connector that provides superior durability compared to the original plastic flange. This thermostat hose connects the radiator to the thermostat housing and is engineered as a direct replacement for BMW OEM part number 11537545890.

Upgraded Metal Connector Design:

• Pre-mounted rugged metal flange replaces the failure-prone OE plastic connector
• Eliminates the most common coolant hose failure point for improved long-term reliability
• Saves installation time with ready-to-install design
• Prevents leaks from reusing old quick connectors and O-rings

OE-Quality Construction:

• Manufactured from durable EPDM rubber material resistant to heat, salt, road debris, oil, and other contaminants
• Identical in form to the original BMW hose with precise sizing and branch configuration
• Features thermoplastic quick connect fittings for reliable leak-free connections
• 30-3/4 inch centerline length with 1-inch inside diameter on both ends
• No cutting, refitting, or adjusting required—fits right the first time

This Rein Automotive replacement hose is compatible with popular BMW models including 1-Series, 3-Series, 5-Series, Z4, and X1 vehicles equipped with N51, N52, N53, and N54 engines from 2006 to 2013. Cross-references to Gates 24565.
