Mercedes-Benz Turbocharger Coolant Line (Return) A2742031000 is a German-engineered, OE replacement that channels coolant from the turbocharger back into the engine cooling loop. This return line helps regulate turbine temperatures, prevents heat soak, and maintains optimal boost efficiency in demanding driving conditions. Built to Mercedes-Benz specifications, it delivers reliable, long‑life cooling performance for turbocharged engines.

Over time, these coolant lines can crack or leak due to heat cycling and coolant exposure, leading to coolant loss, engine overheating, or reduced turbo performance. For select Sprinter, Metris applications, A2742031000 provides a precise, OEM fit that supports consistent cooling and engine reliability.
