Rein CHE0352 Engine Coolant Hose

OE-Style Coolant Hose for European Applications

Rein CHE0352 is an OE-quality engine coolant hose built for European cooling systems that use a direct-fit expansion tank to pipe layout. It is made to match the original hose shape and connection points for a cleaner repair on Audi A4, Audi A4 Quattro, and Volkswagen Passat applications.

Built from EPDM and formed to application-specific dimensions, this Rein coolant hose supports a direct replacement for the factory hose assembly without cutting or refitting. The thermoplastic quick-connect style fitment helps reduce installation time and helps prevent leaks caused by reusing aged connectors and seals.

Key Features

• Application-specific design for direct OE-style replacement
• EPDM hose construction for resistance to heat, salt, road debris, oil, and other contaminants
• Thermoplastic quick-connect fittings match the original hose assembly design
• Reduces installation time with no cutting, refitting, or adjusting required
• Built to SAE J20R4 -D2 standards
• Fits expansion tank to pipe routing on select Audi and Volkswagen models

Detailed Product Information

Rein CHE0352 is an OE quality water hose for European vehicles, engineered to follow the original hose routing and connection style. The hose measures 11.8100 inches centerline length and uses 0.3800 inch inside diameter ends with 0.5900 inch outside diameter ends.

What This Hose Helps Address

• Coolant seepage from cracked or aged hose material
• Leaks at old quick-connect fittings and worn O-rings
• Fitment issues caused by trimming or adapting a universal hose
• Cooling system service delays from mismatched hose geometry
• Contamination-related hose deterioration from heat and road exposure

Installation Notes and Tips

Verify the vehicle’s cooling system routing before installation and compare the original hose shape, branch layout, and connector style to the new part. This hose is direct-fit for the listed Audi A4, Audi A4 Quattro, and Volkswagen Passat applications, so no hose cutting or custom adjustment is required when the vehicle matches the catalog fitment.

Inspect mating surfaces, seals, and connectors during service to help ensure a proper seal and reliable cooling system repair. For best results, replace any visibly worn quick connectors or damaged sealing components during the same repair if the vehicle’s original parts show wear.

Quality Assurance

Rein Automotive OE quality hoses are built as direct replacements for original European cooling system parts, with dimensions and connector details matched to the factory design. CHE0352 is manufactured to support OE-style fitment and consistent service performance in the listed applications.
