Rein CHT0804 Turbocharger Coolant Line

Turbocharger Coolant Line for Mercedes-Benz V8 Applications

Rein CHT0804 is a turbocharger coolant line built for Mercedes-Benz turbocharged cooling circuits that operate under high heat and pressure. It uses OE-quality EPDM and aluminum construction to resist heat, oil, and ozone-related deterioration that can shorten the life of rubber coolant hoses.

• EPDM and aluminum construction for durability in turbocharger coolant service
• Banjo inlet fitting type for the specified OE-style connection
• Resists heat, oil, and ozone exposure that can degrade rubber lines
• Direct replacement part for select Mercedes-Benz turbocharged models
• Rein CHT0804 cross-references OE numbers 2782000751 and 2782001200

Detailed Product Information

This turbocharger coolant line is engineered for Mercedes-Benz vehicles that rely on stable coolant flow to manage turbocharger temperatures. Rein CHT0804 is a practical replacement when the original line shows cracking, seepage, swelling, or heat-related wear. It is listed for 2012-2016 Mercedes-Benz ML500 and ML550, 2013-2016 Mercedes-Benz GL550 and GL500, 2013-2014 Mercedes-Benz GL450, 2016 Mercedes-Benz GLE500, 2016-2018 Mercedes-Benz GLE550, and 2017-2019 Mercedes-Benz GLS550 and GLE500 applications.

Common Issues This Part Addresses

• Coolant seepage at the turbocharger line
• Cracked or hardened hose material from heat cycling
• Oil and ozone damage that weakens rubber coolant lines
• Loss of proper coolant routing in the turbo system
• Service replacement for worn Mercedes-Benz turbo coolant plumbing

Installation Notes and Tips

Verify the banjo-style inlet fitting and compare the original routing before installation. Inspect adjoining seals, clamps, and mating surfaces for wear or contamination, and confirm the replacement line matches the vehicle’s turbocharger coolant path. This part number, CHT0804, is listed for multiple Mercedes-Benz GL, GLE, GLS, ML, and GLK-era turbo applications, so matching the original part and fitment details is important.

Quality Assurance

Rein manufactures turbo hoses with OE-quality materials selected for demanding turbo system service. The EPDM and aluminum construction is specified to help the line withstand heat, oil, and ozone exposure common in turbocharger coolant circuits.
