VADEN Part Groups for OM501
Our catalogue lists 65 VADEN parts for this engine across five main groups. Each group is matched by cross-referencing the original part number.
Cooling-group components for the OM 501 LA's high thermal load. VADEN items are matched by OEM number; confirm fitment against your vehicle reference.
Go to category →Clutch-group parts for the heavy-duty driveline. VADEN products are selected by cross-checking against original references.
Go to category →VADEN components for the OM 501 LA block and engine group. Confirm the correct match via OEM number and build designation (541.9xx).
Go to category →VADEN parts for the transmission/gearbox group. Fitment should be verified by gearbox type and OEM number.
Go to category →VADEN items for the fuel system built around the PLD unit-pump architecture. Because injection hardware is precision-matched, pairing by OEM number is essential.

Vehicles Using the OM501 Engine
The OM 501 LA V6 was used predominantly across the Mercedes-Benz Actros family, and also in industrial and marine applications. Bus and coach use is model-specific and should be verified by VIN.
1996–2003 heavy truck/tractor. The OM 501 LA's launch platform and primary install base; replaced the SK range's older OM 44x V-engines.
Actros compatibility hub →2002/03–2008 heavy truck. The most widespread OM 501 LA fitment; Euro III–V via BlueTec SCR, up to 480 hp on the V6.
Actros compatibility hub →2008–2011 heavy truck. The last V6 Actros generation; same OM 501 LA engine, Mercedes build designation 541.9xx.
Actros compatibility hub →The same 11.9 L V6 was also supplied as a stationary/genset and marine engine (Mercedes-Benz / MTU), sharing many core components with the truck version.
Premium coaches predominantly ran the inline-six OM 457 or the V8 OM 502 LA; direct OM 501 V6 use is limited. Verify per model and VIN.
Export/intercity chassis mostly used OM 457 LA or OM 502 LA; OM 501 V6 fitment is model- and market-specific. Confirm against the chassis rating/VIN before ordering.

Frequently Asked Questions
Are VADEN parts compatible with the OM 501 engine?
VADEN offers the parts listed on this page for vehicles powered by the OM 501 LA V6. Exact fitment should always be confirmed by your vehicle's OEM part number.
How do I select the correct part?
The most reliable method is to cross-check the original (OEM) number on the removed part against the VADEN reference. The engine code alone is not sufficient for part selection.
Which vehicles use the OM 501?
Predominantly the Mercedes-Benz Actros MP1 (1996–2003), MP2 (2002/03–2008) and MP3 (2008–2011); it was also used in industrial/genset and marine applications.
Which part groups are available for this engine?
Our catalogue lists cooling system, clutch, engine, gearbox and fuel-system groups, for a total of 65 VADEN parts for this engine.
Are the OM 501 LA and OM 502 LA the same engine?
No. The OM 501 LA is an 11.9 L V6, while the OM 502 LA is a 15.9 L V8. Shared reference documents list both together, but the highest power and torque figures (e.g. 3,000 Nm) belong to the V8.
Is the OM 501 a turbo-compound engine?
No. The OM 501 LA uses a single turbocharger with charge-air intercooling and has no turbo-compound stage. In the Mercedes-Benz range, turbo-compound is specific to the Euro VI inline-six OM 473.
