Is your Mercedes leaving mystery puddles on the driveway? Our team recently repaired a Mercedes-Benz ML350 BlueTEC Diesel V6 with a leaking engine oil cooler assembly — a common but potentially serious issue on these vehicles.
On this engine, the oil cooler is located deep within the “V” of the motor. Over time, constant heat can cause the factory seals to harden and degrade. Once this happens, engine oil can leak down the back of the engine, creating puddles, unpleasant smells and a messy build-up of oil residue.
This ML350 was showing signs of an oil leak caused by failing oil cooler seals. If ignored, this type of leak can lead to low engine oil levels, increased risk of engine damage and oil staining on driveways or parking areas.
Because the oil cooler sits beneath the upper engine components, this was a detailed repair requiring careful strip-down and reassembly. Our technicians:
The result was a clean, properly sealed engine and an ML350 ready to stay leak-free for years to come.
If your Mercedes-Benz or other European vehicle is losing oil, leaving marks where it is parked, or producing a burnt-oil smell from under the bonnet, it is worth having it checked early. Prompt repairs can help prevent a small seal failure from turning into a much more expensive engine problem.
