OE-Style Turbo Coolant Hose for Mercedes-Benz
Restore proper coolant flow in the turbo system with the Rein CHT0743 turbocharger coolant line. This OE-quality replacement is built for the return side on select Mercedes-Benz models and is designed to match factory fit, form, and function.
Compatible With Mercedes-Benz GLE63 AMG, SL550, S63 AMG, and other listed applications, this hose is a direct-fit solution for replacing a leaking or deteriorated turbo coolant line. The Rein CHT0743 is built for the demands of turbocharged cooling circuits and is made to resist heat, oil, and ozone exposure.
Key Features
- OE-quality turbocharger coolant line for application-specific Mercedes-Benz fitment
- Direct-fit replacement for the return (right) side
- EPDM and aluminum construction for durability in high-heat engine bay conditions
- Helps restore proper coolant routing in turbocharged systems
- Rein CHT0743 cross-references OE part number 2782001851
Detailed Description
Rein CHT0743 is a turbocharger coolant hose engineered for Mercedes-Benz vehicles that use a return-side right-hand coolant line. It is manufactured to OE-quality standards so it installs in the factory location and performs like the original component. This makes it a practical replacement for Mercedes-Benz GLE63 AMG, SL550, S63 AMG, S550, E550, and other listed models.
The hose material is designed to handle the thermal and chemical stress common in turbocharged cooling systems. If the original line is cracked, softened, or leaking, replacing it with the Rein CHT0743 helps maintain stable coolant circulation around the turbocharger assembly.
What It Helps Fix
- Coolant leaks at the turbocharger return line
- Cracked or heat-damaged hose material
- Oil- and ozone-related rubber deterioration
- Improper coolant routing in the turbo system
- Loss of factory-style fitment on the right return side
Installation Notes and Tips
Verify the vehicle’s year, model, and return (right) side application before installation. Inspect adjacent seals, clamps, and mating surfaces for wear, and replace any damaged components during service to avoid repeat leaks. Confirm the hose routing matches the original layout on the Mercedes-Benz turbo cooling circuit.
Quality Assurance
Rein manufactures this coolant hose as an OE-quality replacement designed for dependable service in turbocharged applications. Part number CHT0743 is backed by a 24-month or 24,000-mile warranty.
