Detailed description

Rein ECK0026 is an application-specific engine oil cooler kit for Mercedes-Benz OM642 diesel engines. It is intended for vehicles that experience oil leaks inside the V of the engine, which can lead to low oil level warnings, oil stains under the vehicle, and reduced oil level readings. The kit combines the oil cooler with the seals, gaskets, and stretch bolts needed to complete the repair without sourcing separate components. Part number ECK0026 is a direct service solution for Mercedes-Benz Sprinter, GL, ML, R, E, S, GLE, and GLS applications listed in the fitment data, as well as Freightliner Sprinter models using the same engine family.

Rein’s OE Quality Problem Solver line focuses on complete repair coverage for known failure points. For this oil cooler kit, that means upgraded sealing materials and matched service parts for the OM642 platform. This part cross-references Genuine 6420940080 and 6421420481 for the same application.

What it is used for

• Oil leaks from the engine valley area
• Low oil level warnings on the instrument cluster
• Oil stains or puddles beneath the vehicle
