Rein CHT0805 Turbocharger Coolant Line - Return (Left)

Turbocharger Coolant Line for Mercedes-Benz

Rein CHT0805 is a turbocharger coolant line built for Mercedes-Benz turbo systems that rely on stable coolant flow at high operating temperatures. It uses EPDM and aluminum construction to resist heat, oil, and ozone exposure that can degrade rubber lines over time.

Compatible With select 2011-2013 Mercedes-Benz CL550, CLS500, CLS550, E500, E550, S500, S550, SL500, SL550, CLS63 AMG, E63 AMG, and S63 AMG applications with a left-side return configuration.

Key Features

• 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 shorten hose life
• Direct-fit replacement for the listed Mercedes-Benz return (left) applications
• Rein part number CHT0805 for easy identification

Detailed Description

This Rein turbocharger coolant line is engineered for Mercedes-Benz vehicles equipped with turbocharged power systems that route coolant through a left-side return line. The EPDM hose material helps maintain flexibility and sealing performance, while the aluminum section supports the connection points used in the cooling circuit. Rein CHT0805 is a practical OE-style replacement for service work on CL550, CLS500, CLS550, E500, E550, S500, S550, SL500, SL550, CLS63 AMG, E63 AMG, and S63 AMG models listed in the fitment data. This part cross-references Mercedes-Benz 2782001100 for the same application.

Common Issues This Part Can Address

• Coolant seepage at a worn turbocharger return line
• Cracking or hardening from heat-aged rubber tubing
• Oil and ozone-related hose deterioration
• Leak concerns at the banjo-style connection point
• Loss of coolant routing integrity in the turbo cooling circuit

Installation Notes and Tips

Verify the vehicle’s model year, engine application, and left-side return routing before installation. Confirm the banjo fitting style and line orientation against the removed part to ensure correct placement. Inspect adjacent seals, mating surfaces, and coolant passages for wear or contamination before reassembly.

Quality Assurance

Rein manufactures turbo hoses with OE-quality materials selected for demanding automotive turbo systems. The material construction is intended to withstand heat, oil, and ozone exposure commonly found in turbocharger coolant service.
