Where is the Cummins engine number located?
2 Answers
Cummins engine number is located above the interface between the engine and the transmission. Relevant information is as follows: 1. Information 1: Cummins engines are designed and manufactured by Cummins Inc. The displacement of Cummins engines ranges from 1.4 to 91 liters, with a power range covering 31 to 3500 horsepower. 2. Information 2: They are widely used in heavy-duty trucks, medium-duty trucks, buses, recreational vehicles, light commercial vehicles, and pickup trucks for highway applications, as well as in off-highway equipment such as construction machinery, mining equipment, agricultural machinery, marine, and railway applications. 3. Information 3: Cummins engines are renowned for their reliability, durability, and fuel economy in the industry. They consistently maintain a leading position in meeting increasingly stringent emissions standards for automotive, off-highway mobile equipment, and marine applications.
The location of the Cummins engine serial number can actually vary quite a bit. I researched this last time when helping a friend look up information. The most common spot is usually on the metal surface of the engine block near the oil pan on the right side, stamped deeply with steel seals—you’ll need to clean it well to see clearly. Some older models might hide it on the back of the oil filter base, requiring a flashlight to spot. Newer IS series models may have moved it to the side of the intake manifold or the edge of the flywheel housing. If you really can’t find it, the engine’s nameplate will definitely have the full model and serial number—it’s a small aluminum plate attached to the side of the cylinder head. This also depends on the installation method; it might be easier to locate on trucks compared to construction machinery. I’d suggest checking these areas first, and if all else fails, removing the air filter housing might reveal more accessible spots.
