Rein CHR0970 Radiator Coolant Hose - Upper

Radiator Coolant Hose Overview

The Rein CHR0970 radiator coolant hose is a standard replacement hose for European cooling systems. It is built as a direct OE-style replacement with the same general size, shape, and quick-connect design expected from the original hose assembly.

Compatible With Mercedes-Benz GLC300, Mercedes-Benz GLC350e, and Mercedes-Benz E300 upper radiator hose applications.

Key Features

• Direct replacement design for OE hose and hose assembly applications.
• Thermoplastic quick-connect fittings for a factory-style connection.
• Standard replacement grade for routine cooling system service.
• Black finish for a clean, OE-style appearance.
• Rein CHR0970 fitment for select Mercedes-Benz cooling system applications.

Detailed Description

Rein Automotive designs the CHR0970 to match the original hose layout used in select Mercedes-Benz cooling systems. The hose follows OE dimensions and branch geometry, and the thermoplastic quick-connect fittings support a factory-style connection at the radiator circuit. This makes it a practical choice when replacing a worn or damaged upper radiator coolant hose on Mercedes-Benz GLC300, Mercedes-Benz GLC350e, or Mercedes-Benz E300 applications.

The CHR0970 is intended for upper hose service on 2016-2019 Mercedes-Benz GLC300, 2018-2020 Mercedes-Benz GLC350e, and 2017-2019 Mercedes-Benz E300 models. Rein CHR0970 is built as a standard replacement part for cooling system repair where OE-style fit and routing matter.

This part cross-references 2535013782 for the same application.

What It Helps Fix

• Coolant leaks from a cracked or aged radiator hose.
• Loose or damaged quick-connect hose ends.
• Cooling system service after hose swelling or hardening.
• Improper hose routing caused by a failed replacement part.
• Loss of cooling system integrity at the upper hose connection.

Installation Notes

Verify the vehicle year, model, and upper hose application before installation. Inspect the mating fittings and surrounding cooling system components for wear, contamination, or damage before connecting the new hose. Confirm the hose routing matches the original layout so the assembly seats correctly.

Quality Assurance

Rein Automotive positions this hose as OE quality and direct replacement for original equipment cooling system service. The CHR0970 is engineered to follow the original hose size, shape, and connector style used on the listed Mercedes-Benz applications.
