Rein CHE0519 Engine Coolant Hose - Expansion Tank (Upper) To Pipe

OE Quality Coolant Hose for European Fitment

Rein CHE0519 is an OE quality engine coolant hose for European vehicles that require a direct-fit replacement at the expansion tank upper-to-pipe connection. It is built for Volkswagen CC, Passat, and Passat CC applications where the original hose routing and quick-connect design must match the factory layout.

For Volkswagen Passat coolant hose replacement and Volkswagen CC upper expansion tank hose service, CHE0519 follows the OE shape and connection style to simplify repair work and restore proper coolant routing.

Key Features

• Direct replacement for the original engine coolant hose assembly
• Reduces installation time by matching OE dimensions and branch shape
• No cutting, refitting, or adjusting the hose during installation
• 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 for application-specific European fitment

Detailed Description

Rein CHE0519 is engineered as a complete OE quality water hose for European cooling systems. The hose is shaped to match the factory part, including the thermoplastic quick-connect fittings called for by the original design. That makes it a practical choice when replacing a worn or leaking coolant hose on a Volkswagen CC, Passat, or Passat CC with the expansion tank upper-to-pipe routing.

This part number, CHE0519, is built for direct-fit service and is identified by interchange reference 1K0122447FT for the same application. If you are searching for a Rein coolant hose for Volkswagen Passat or a Rein water hose for Volkswagen CC cooling system repair, CHE0519 provides the OE-style layout needed for a clean replacement.

What It Helps Fix

• Coolant leaks at the expansion tank upper hose connection
• Cracked, hardened, or heat-aged coolant hose material
• Fitment issues caused by non-OE hose shape or length
• Repeat leaks from reused quick connectors or worn O-rings
• Cooling system service delays caused by trimming or refitting a hose

Installation Notes and Tips

Verify the vehicle’s cooling system routing before installation and match the hose to the expansion tank (upper) to pipe position listed for the application. CHE0519 is application-specific, so the OE connection style and hose shape should be checked against the removed part before assembly. For best results, inspect mating surfaces and seals during service and replace any damaged connectors or O-rings as needed.

Quality Assurance

Rein Automotive focuses on OE quality replacement parts for European vehicles, with coolant hoses built to mirror the original hose geometry and connector design. CHE0519 is made as a direct-fit replacement for the factory cooling hose layout on the listed Volkswagen applications.
