Rein CHR0664 Radiator Coolant Hose - Lower

OE-Style Lower Radiator Hose

Rein CHR0664 is an OE-quality radiator coolant hose built as a direct replacement for the original lower hose assembly. It is made for European vehicle cooling systems and follows the factory hose shape, branch layout, and quick-connect design for a precise service fit.

Compatible with Mercedes-Benz Sprinter 2500, Sprinter 3500, and Sprinter 3500XD lower radiator hose applications across 2007-2022 model years, this hose supports clean cooling-system service on diesel van platforms where exact routing matters. Rein CHR0664 is also a direct OE-style replacement for the same application on select Dodge Sprinter models.

• Direct replacement for OE radiator hose assemblies
• Branched hose design with factory-style routing
• Thermoplastic quick-connect fittings for OE-style connection points
• EPDM hose construction for cooling-system durability
• Resists heat, salt, road debris, oil, and other contaminants
• Reduces installation time by eliminating hose cutting and refitting
• Helps prevent leaks and repeat repairs from reused connectors and o-rings

Detailed Application Overview

This lower radiator coolant hose is engineered for the Mercedes-Benz Sprinter 2500, Sprinter 3500, and Sprinter 3500XD, with fitment covering 2007-2022 vehicles in the lower position and specific engine or roof-AC notes where listed. The Rein CHR0664 follows OE dimensions and connector style so the replacement matches the original hose assembly rather than requiring adaptation.

The EPDM construction and branched layout make this hose a practical choice for cooling-system repair when the original hose has softened, cracked, or developed connector issues. Rein CHR0664 is built to restore proper coolant routing and maintain a secure seal at the factory connection points.

Common Problems This Hose Can Address

• Coolant leaks at the lower radiator hose connection
• Cracked, swollen, or heat-aged hose material
• Damaged quick-connect fittings or worn o-rings
• Poor fit from universal hose substitutions
• Repeat cooling-system repairs caused by reused connectors

Installation Notes

Verify the vehicle’s year, model, engine configuration, roof-AC note, and lower hose position before installation. Because this is an application-specific OE-style hose, no cutting, refitting, or adjusting should be needed when the correct part is selected. Inspect mating surfaces and replace worn seals or connectors as needed during cooling-system service.
