PRODUCT DESCRIPTION

Upgrade Your Sprinter: Meet the Engine Oil Cooler Kit!

Hey, Sprinter owners! Are you tired of pushing your engine to the limit only to worry about overheating? After four years of rigorous testing, we’re excited to introduce our Engine Oil Cooler Kit, designed specifically for your 3.0 Ltr. engine.

Why oil temps climb on long grades

  • Exhaust heat (EGT) moves into the turbo housing and into the engine oil.

  • Piston oil squirters add more heat load to the oil film.

  • The coolant/oil heat exchanger saturates; when both systems are hot, oil runs hotter than coolant.

  • On sustained pulls, oil becomes the thermal sink and creeps past 240–250 °F even if coolant looks normal.

Why add an oil cooler to the OM642 (Sprinter)

  • The OM642 uses oil as a primary cooling medium for the turbo and pistons.

  • Under continuous load (mountain passes, towing, heavy vans), oil temps exceed the ~220 °F sweet spot and push toward the limits of MB 229.51/229.52 oils.

  • The factory coolant/oil exchanger is sized for typical European duty cycles. North American RV/cargo builds + long climbs = more heat than the stock system can shed.

What a dedicated external oil cooler does

  • Bypasses the coolant/oil bottleneck and adds direct airflow heat rejection.

  • Lowers equilibrium oil temps by ~20–40 °F, keeping temps in a safe continuous range.

  • Cooler oil = more stable viscosity, less thermal breakdown, and longer turbo & bearing life.

Plain terms

  • On long grades your oil acts as the heat dump for the turbo and pistons. An auxiliary oil cooler gives the oil its own radiator, taking load off the coolant so both systems run cooler—ideal for heavy Sprinters on sustained climbs.

Why This Upgrade is Essential:

  1. Factory Cooler? Not Enough: The factory oil cooler is just not up to the task. With a rating of only 52,000 BTU, it struggles to keep your oil temperatures in check during heavy loads or challenging conditions. If you’re towing, climbing hills, or just driving in the heat, the factory cooler can leave your engine oil hotter than it should be—leading to increased wear and tear on the engine's internals and the turbo charger.
  2. Keep Your Oil Cool: Our kit, with its additional cooling capacity of 29,000-40,000 BTU, helps lower engine oil temperatures by up to 30°F. This means your engine can perform at its best without the constant worry of overheating. Consider it a vital upgrade for maintaining your engine’s health, especially when you need it most!
  3. Easy Installation: We designed our kit to sandwich right in line with the OEM oil filter housing, making installation a breeze—no advanced tools or skills required! Plus, we’re creating an installation video to make it even simpler.
  4. Tested in Real Conditions: As an owner of multiple HEAVY Sprinter vans —I know the struggle of managing oil temperatures, especially when towing a 20' enclosed snowmobile trailer. I’ve seen how essential it is to keep oil temperatures down for optimal performance, and this kit is the solution
