OE-Style Lower Radiator Hose for Mercedes-Benz

Rein CHR0669 is an OE-quality radiator coolant hose built for European vehicles that need a direct replacement at the lower cooling circuit. It is shaped to match the original hose assembly, including branched routing and thermoplastic quick-connect fittings for a cleaner service fit on Mercedes-Benz C300, C350, and E350 applications.

For Mercedes-Benz C300 lower radiator hose replacement, Mercedes-Benz C350 lower coolant hose service, or Mercedes-Benz E350 lower radiator hose repair, CHR0669 is built to match the original layout and connection points.

  • Direct replacement for OE radiator hose assemblies

Detailed Product Overview

Rein CHR0669 is designed around the original hose geometry, including centerline length, branch shape, and connector style, so the replacement follows the factory cooling system layout. The EPDM hose material is selected for durability in demanding underhood conditions, while the OE-style quick-connect design helps maintain a secure seal at the connection points. This makes it a practical choice for restoring proper coolant flow on 2008-2012 Mercedes-Benz C300, 2008-2011 Mercedes-Benz C350, and 2010-2011 Mercedes-Benz E350 lower hose applications.

This part cross-references Genuine 2045013782 for the same application. CHR0669 is the part number to reference when ordering a lower radiator coolant hose for these Mercedes-Benz models.

What It Helps Address

  • Coolant leaks at worn hose connections
  • Fitment issues caused by reused quick connectors or old O-rings
  • Installation delays from cutting, refitting, or adjusting the hose
  • Cooling system service on a damaged or aging lower radiator hose
  • Comback repairs related to poor sealing at the hose ends

Installation Notes and Tips

Inspect the mating connectors and sealing surfaces before installation. Replace damaged O-rings or worn connection components as needed, and verify that the hose routing matches the original lower position on the vehicle. CHR0669 is a direct-fit replacement, so no cutting or reshaping of the hose should be required when installed on the listed Mercedes-Benz applications.

Quality Assurance

Rein Automotive positions this hose as an OE-quality replacement for European vehicles, with construction and connector design based on the original hose assembly. CHR0669 includes a 24-month warranty with a 24,000-mile distance limit.
