Description
Reviews (0)

The Mercedes-Benz G-wagon 350 TD models in the W463 generation were fitted with an OM603 3.5-litre inline-six turbodiesel engine and a 4-speed automatic transmission. The earlier W460 models did not come from the factory with this specific engine.

Engine Details (OM603 350 TD)

The OM603 engine in the G 350 TD is known for its durability but had some specific issues related to its application in the G-Wagon.

Type: 3.4-liter (3449 cm³) inline-six cylinder, turbocharged diesel engine.
Performance: Produced around 136 horsepower (100 kW) at 4600 RPM and 225 lb-ft (305 Nm) of torque at 1800 RPM.
Reliability: Generally considered a very robust engine, but in the G 350 TD application, some examples were known to consume oil and had a tendency for cylinder heads to crack. The engine’s bottom end is largely the same as the reliable 3.0L version.
Fuel System: It uses an indirect injection fuel system.

Gearbox Details

The G 350 TD was equipped with a specific automatic transmission designed to handle the G-Wagon‘s low gearing and off-road requirements.

Type: 4-speed automatic transmission.
Control: This was a mechanically controlled unit, unlike the electronically controlled 5-speed automatic introduced later with the OM606 engine in the G 300 TD.
Performance: The gearing of the original transmission was designed for off-road conditions and lower power, which means they are generally quite low-geared for modern highway speeds.

Compatibility and Availability

W460 vs. W463: The OM603 3.5 TD engine was a W463 factory fitment. The W460 models used earlier engines (like the 250 GD and 300 GD) and generally require significant modification for an engine swap, including changes to wiring, fuel systems, and potentially propshafts.
Parts: A wide range of engine and gearbox spare parts (both new OEM and aftermarket) are available through specialist G-Wagon retailers and general parts suppliers in the UK, including complete assemblies, gaskets, and filters.
Conversions: Many G-Wagon owners perform engine conversions for more power. The original 4-speed auto gearbox may be too low-geared for more powerful modern engine swaps, and a 5-speed electronically controlled automatic is often preferred for a better all-around driving experience.
