Rein CHR0360R Radiator Coolant Hose - Lower - Reservoir To Radiator

OE-Style Radiator Hose for Mercedes-Benz

The Rein CHR0360R radiator coolant hose is a direct-fit replacement for select Mercedes-Benz cooling systems. Built to OE dimensions and formed for the correct branch shape, it helps restore proper coolant routing on the lower reservoir-to-radiator connection.

Compatible with 1998-2003 Mercedes-Benz E320 and 2000-2002 Mercedes-Benz E430, this Rein radiator hose is made for European vehicle applications that require an exact replacement profile. The CHR0360R is designed to reduce installation time while maintaining the fit and sealing expected from an OE-style hose assembly.

Key Features

• Direct replacement for the original radiator coolant hose assembly
• OE-matched size and shape for the branch and connection points
• Thermoplastic quick-connect fittings for proper OE-style fitment
• EPDM hose construction for heat and coolant system durability
• Resistant to heat, salt, road debris, oil, and other contaminants
• SAE J20 R4 D1 compliant construction
• Maximum working pressure: 149 psi

Detailed Description

Rein CHR0360R is an OE quality radiator hose engineered for European vehicles where exact routing and connector fit are critical. It is built as a single radiator coolant hose with a black EPDM body, protective shielding, and application-specific dimensions that match the original lower reservoir-to-radiator layout. For Mercedes-Benz E320 and Mercedes-Benz E430 applications, this hose supports a clean replacement without altering the factory hose path.

This part cross-references Mercedes-Benz OE number 1122030082 for the same application. The CHR0360R is a practical choice when replacing a worn or leaking Mercedes-Benz E320 radiator hose or Mercedes-Benz E430 lower coolant hose and when maintaining OE-style connector geometry matters.

Common Problems This Hose Can Help Solve

• Coolant leaks at aged hose connections
• Cracked or hardened rubber from heat cycling
• Poor sealing caused by worn quick-connect interfaces
• Incorrect hose routing after prior repairs
• Repeat cooling system service from reused connectors or seals

Installation Notes and Tips

Verify the vehicle application before installation and compare the original hose routing, end diameters, and connector style to the CHR0360R. Because this is an application-specific OE-style hose, no cutting, refitting, or adjusting of the hose should be necessary when used on the listed Mercedes-Benz models.

Inspect mating surfaces, quick connectors, and O-rings during service to help prevent leaks after installation. Confirm the lower reservoir-to-radiator routing on 1998-2003 Mercedes-Benz E320 and 2000-2002 Mercedes-Benz E430 models before final assembly.

Quality Assurance

Rein designs this radiator hose as an OE quality replacement for European vehicles, with fit and connector geometry based on the original manufacturer’s specifications. Warranty coverage is 24 months or 24,000 miles.
