OE-Style Upper Radiator Hose

Rein CHR0456 is an OE-quality radiator coolant hose for European cooling systems that require a direct replacement with the correct branch shape and thermoplastic quick-connect fittings. It is built for upper hose applications on select Mercedes-Benz models, including C250, C300, C350, C230, E350, and GLK350.

For Mercedes-Benz upper radiator hose replacement, CHR0456 follows the original hose layout to help restore proper coolant routing without trimming or reworking the hose. The EPDM construction is made for heat, salt, road debris, oil, and other underhood contaminants.

Key Features

  • Direct replacement for OE radiator hose assemblies
  • Application-specific branched hose design
  • Thermoplastic quick-connect fittings for OE-style connection points
  • EPDM hose material for cooling-system service
  • Resistant to heat, salt, road debris, oil, and contaminants
  • Reduces installation time with no cutting, refitting, or adjusting
  • Helps prevent leaks and repeat repairs from reused quick connectors and O-rings
  • Built to SAE J20 R4 D1 standards

Product Details

Rein CHR0456 is a black upper radiator coolant hose with a branched layout, 33.8-inch centerline length, and two quick-connect fittings. It is engineered to match OE dimensions and connection style, making it a practical choice for Mercedes-Benz cooling system service where the original hose assembly has aged, cracked, or begun to seep coolant. This part cross-references Genuine 2045010382 for the same application.

What It Helps Fix

  • Coolant leaks from a worn or cracked upper radiator hose
  • Broken or weakened quick-connect interfaces
  • Improper hose fit after prior repairs or reuse of old connectors
  • Heat-related hose deterioration in the engine bay
  • Cooling-system service issues on Mercedes-Benz C250, C300, C350, C230, E350, and GLK350 applications

Installation Notes

Install as an application-specific replacement on the upper radiator hose position. Verify connector engagement, hose routing, and sealing surfaces before filling and bleeding the cooling system. Because this hose is built to OE dimensions, no cutting or hose reshaping is required when used on the listed Mercedes-Benz applications. Confirm the vehicle’s emissions configuration and VIN breakpoints where noted in fitment.

Quality Assurance

Rein Automotive OE-quality hoses are built as direct replacements for original hose assemblies and are manufactured to match OE branch geometry and connector style. CHR0456 is backed by a 24-month or 24,000-mile warranty.
