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.
