Sprinter Engine Oil Cooler | Mercedes-Benz Sprinter 3.0L Diesel (2008–2023)

Boost Cooling Performance & Protect Your OM642 Engine

The Sprinter Engine Oil Cooler Kit is a must-have upgrade for Mercedes-Benz Sprinter vans with the 3.0L V6 OM642 Diesel (2008–2023). Built for towing, hauling, and overlanding, this kit addresses the Sprinter’s biggest weakness: high oil temperatures on long grades and under heavy loads. By adding a dedicated external oil cooler, you prevent overheating, protect engine components, and extend oil life — ensuring your Sprinter is ready for any adventure.

Why Oil Temps Climb on Sprinter OM642 Engines

The Sprinter’s factory cooling system struggles on long mountain passes, when towing trailers, or when carrying heavy camper van conversions. Here’s why oil temps soar past 240–250 °F, even when your coolant looks “normal”:

• Exhaust heat drives oil temps: High exhaust gas temps (EGTs) dump heat into the turbo housing, which transfers directly into the engine oil.

• Piston oil squirters add load: Combustion heat flows into the thin oil film, raising oil temperature further.

• Coolant/oil exchanger bottleneck: The factory heat exchanger tries to balance oil and coolant temps, but when both are hot, oil becomes the “thermal sink” for turbo and piston heat.

• Result: Oil temps creep higher and higher on sustained climbs — putting stress on bearings, seals, and your turbocharger.

Why the OM642 Needs an Auxiliary Oil Cooler

The OM642 3.0L Diesel relies heavily on oil for cooling pistons and turbo bearings. In North American use cases (longer climbs, higher GVWR cargo vans, RV conversions), the factory cooler is undersized.

Adding our Sprinter Engine Oil Cooler Kit provides:

• 20–40 °F lower oil temperatures on long grades.

• Direct airflow cooling that bypasses the coolant/oil bottleneck.

• Stable viscosity and reduced oil breakdown, extending oil life.

• Longer turbo and bearing life, since heat stress is reduced.

• Protection under heavy loads where the stock system consistently runs too hot.

In plain terms: the stock design makes oil act like a heat dump. On mountain passes or when towing, oil temps just keep climbing. Our kit gives oil its own dedicated “radiator,” relieving the burden on coolant and stabilizing temps for safe, continuous operation.
