Rein CHR0733 Radiator Coolant Hose - Upper

OE-Style Upper Radiator Hose for Sprinter

Rein CHR0733 is an OE-quality radiator coolant hose built for European vehicle cooling systems that need a direct replacement, not a universal trim-to-fit part. It matches the original hose shape and branch layout for a cleaner install on Mercedes-Benz Sprinter and Dodge Sprinter upper hose applications.

Designed for 2010-2018 Mercedes-Benz Sprinter 2500 and Sprinter 3500 upper hose service, as well as 2007-2009 Dodge Sprinter 2500 and Sprinter 3500 upper hose applications, CHR0733 helps restore proper coolant routing with a factory-style fit.

Key Features

• Direct replacement radiator coolant hose for application-specific fitment
• Reduces installation time by eliminating hose modification
• No cutting, refitting, or adjusting required
• Helps prevent leaks and repeat repairs from reused quick connectors and O-rings
• EPDM hose construction resists heat, salt, road debris, oil, and other contaminants
• Black single-hose design with OE-style branch and connector geometry

Detailed Description

Rein CHR0733 is engineered as an OE-style upper radiator hose for Mercedes-Benz Sprinter and Dodge Sprinter diesel applications. The hose follows the original equipment dimensions, branch shape, and thermoplastic quick-connect interface so the cooling system can be serviced without altering the part to make it fit. This approach supports a more accurate repair on the Mercedes-Benz Sprinter 2500, Mercedes-Benz Sprinter 3500, and Mercedes-Benz Sprinter 3500XD upper hose positions covered by the fitment data.

This part cross-references 68013638AA and 9065010582 for the same application. Rein CHR0733 is a practical choice when replacing a worn or leaking upper radiator hose on a Sprinter cooling system.

What This Hose Helps Address

• Coolant leaks at the upper radiator hose connection
• Cracked, swollen, or heat-aged hose material
• Poor sealing caused by reused quick connectors or O-rings
• Cooling system service delays from hose modification
• Fitment issues from non-OE hose geometry

Installation Notes and Tips

Verify the vehicle year, model, engine output, and upper hose position before installation. Inspect the mating connectors and sealing surfaces for wear, contamination, or damage, and replace any compromised seals before assembly. Because this hose is application-specific, it installs without cutting or refitting when matched to the correct Sprinter application.

Quality Assurance

Rein positions this hose as an OE-quality replacement for European vehicles, with construction that mirrors the original hose assembly for size, branch shape, and connector design. Part number CHR0733 is backed by a 24-month or 24,000-mile warranty.
