The OM642 is a 3.0-litre V6 diesel used across a wide range of Mercedes models, including the GLK X204. GLK versions used several different OM642 engine codes, including OM642.961, OM642.832 and OM642.835, so the exact engine code must be checked before purchase.

Typical Overhaul Work

A professional OM642 rebuild can include:

• Cylinder-head inspection and machining
• New valve-stem seals
• New head gasket
• New main and connecting-rod bearings
• New piston rings
• Cylinder honing
• Crankshaft inspection/polishing
• Replacement of damaged valves/camshaft components
• New seals and gaskets
• Inspection and testing of the oil system

One current OM642 overhaul programme specifically describes machining the block and crankshaft, renewing wear components and addressing known weak points.

GLK Compatibility

For the Mercedes GLK X204, the 3.0 CDI/BlueTEC versions include different OM642 variants. For example:

• GLK 320 CDI 4MATIC — OM642.961, 165 kW
• GLK 350 CDI 4MATIC — OM642.832, 170 kW
• GLK 350 CDI 4MATIC — OM642.835, 195 kW

Therefore, “OM642” alone is not sufficient to guarantee compatibility. Match the replacement engine to the original engine code, VIN, power output, emissions specification and drivetrain.
