Rein CHR0699 Radiator Coolant Hose - Upper or Upper - Main Radiator

OE-Style Radiator Hose for Mercedes-Benz Cooling Systems

Rein CHR0699 is an OE-quality radiator coolant hose built for European cooling systems that require an exact replacement. It matches the original hose shape and branch layout, including thermoplastic quick-connect fittings, to support a direct repair on Mercedes-Benz GLE, GLS, and ML applications.

Compatible With 2012-2019 Mercedes-Benz GLE, GLS, and ML models in upper radiator positions, this hose is built to reduce installation time and avoid the fitment issues that come from modifying a hose during service.

Key Features

• Direct OE-style replacement for radiator hose and hose assembly applications
• Reduces installation time by matching original dimensions and routing
• No cutting, refitting, or adjusting the hose during installation
• Thermoplastic quick-connect fittings match the OE design
• Helps prevent leaks and repeat repairs caused by reusing old quick connectors and O-rings
• Resists heat, salt, road debris, oil, and other contaminants

Detailed Product Description

Rein CHR0699 radiator hose is engineered for Mercedes-Benz cooling system service where the original hose must be replaced with a part that follows OE dimensions and connection style. The hose is shaped to match the factory routing and branch geometry, and the quick-connect ends are designed to align with the original assembly for a cleaner repair. This makes it a practical choice for Mercedes-Benz GLE400 upper main radiator service, GLE350 upper hose replacement, and similar upper radiator hose applications on GLS450, GLE43 AMG, GLE550e, GL450, GLE450 AMG, ML350, and ML400 models.

This part cross-references Mercedes-Benz OE number 1665000075 for the same application. Rein CHR0699 is a direct-fit radiator coolant hose for technicians and owners who need an OE-style replacement without altering the hose during installation.

Common Problems This Hose Helps Address

• Coolant leaks at worn or damaged hose connections
• Cracked, swollen, or heat-aged upper radiator hoses
• Repeat leaks from reused quick connectors or O-rings
• Poor fitment after trimming or modifying a replacement hose
• Cooling system service delays caused by non-matching hose geometry

Installation Notes and Tips

Verify the vehicle’s upper radiator hose routing and connector style before installation. Because this hose is application-specific, compare the original part shape, branch layout, and quick-connect ends to the removed component before service. Clean the mating surfaces and inspect adjacent cooling system components for wear, contamination, or damage that could affect sealing.

Quality Assurance

Rein designs OE-quality cooling components for European vehicles, with replacement parts built to follow original manufacturer dimensions and connection details. CHR0699 includes a 24-month or 24,000-mile warranty.
