Turbocharger Coolant Line for Mercedes-Benz

Rein CHT0803 is a turbocharger coolant line built for Mercedes-Benz turbocharged applications that use a left-side return connection. It is made with EPDM and aluminum materials to handle the heat, oil exposure, and ozone conditions common in turbo cooling circuits.

Use this Rein turbo coolant line when replacing a worn or leaking return line on select Mercedes-Benz models, including S63 AMG, SL550, and GLE63 AMG applications.

Key Features

What It Helps Address

• Coolant seepage at the turbocharger return line
• Cracked or heat-aged rubber in the turbo cooling circuit
• Oil and ozone-related hose deterioration
• Loss of coolant flow through the turbocharger system
• Service replacement for a damaged left return line

Installation Notes

Confirm the vehicle’s model year and left-side return routing before installation. The banjo-style inlet fitting should match the original connection points, and the line should be inspected for proper seating and routing after installation. This part cross-references OE numbers 2782000200 and 2782001300 for the same application.

Quality Assurance

Rein turbo hoses are manufactured with OE-quality materials selected for turbo system heat and fluid exposure. The EPDM and aluminum construction is used to resist the conditions that commonly shorten the life of rubber coolant hoses in Mercedes-Benz turbo applications. Rein part number CHT0803 is built for direct replacement service on the listed vehicles.
