Cummins N14 Engine Serial Number Location

Cummins is an Indiana-based company that manufactures diesel and natural-gas powered engines for medium- and heavy-duty trucks, buses, RVs and industrial-use vehicles. Identifying whether a Cummins engine is installed in your vehicle takes only a few simple steps.

Step 1

Pop your vehicle's hood and locate the engine. Look for the Cummins logo (it's the letter 'C' with the word 'Cummins' written diagonally across the letter's top left corner).

Step 2

Consult your vehicle's owner's manual to identify whether your vehicle has a Cummins engine. Look for the section regarding engine specifications or parts.

Step 3

Locate your vehicle's Vehicle Identification Number (VIN). This 17-digit number can be found at the top of your vehicle's dashboard on the driver's side, as close to the front window as possible (it is also printed on most vehicle registration cards). If the sixth digit is a '2' or '3,' the vehicle is a Dodge Ram 2500 or 3500. This Dodge model comes with a Cummins engine standard; look at the eighth digit in the VIN sequence to identify exactly what type of Cummins engine is installed.

Step 4

Visit the Cummins products home page and click on the link for 'Engines.' Select your type of vehicle from the drop-down menu; you'll be able to choose from on- or off-road vehicles, as well as recreational equipment like boats. Doing this will direct you to a new page with information regarding the types of Cummins engines used in the various vehicle types.

Step 5

Locate the eight-digit serial number on your Cummins engine; it is printed on a dataplate affixed to the engine. The exact location of the dataplate varies depending the model engine, yet it's typically on the top or side of the rocker cover or housing unit. This dataplate will also have the engine's model printed on it.

Research the engine specifications for your model type (found on the dataplate). The Cummins Diesel Specs website is a good place to turn for engine specification information.

There are three major manufacturers of truck engines in the United States--Detroit Diesel, Caterpillar and Cummins. In addition to the major three, Navistar also produces proprietary engines built specifically for its vehicles. All truck engines consist of a model and serial number to help repair shops and truck-parts personnel decide how to best service the truck owner.

Proprietary Engines

Cummins N14 Engine Serial Numbers

Many truck manufacturers used the same model engines in their on-highway vehicles. During the 1980s and 1990s, Detroit Diesel, Caterpillar and Cummins built engines for most of the truck manufacturers in the United States. A Freightliner, Peterbilt or a Navistar may have been built with a Detroit Diesel, Caterpillar or Cummins engine up until the late 1990s. Beginning in the early 2000s, however, engine companies began to produce engines for specific truck manufacturers. Detroit Diesel engines are now used exclusively in Freightliner trucks. Caterpillar and Cummins engines are used by Peterbilt, Kenworth and Freightliner. Navistar engines are still proprietary to International Harvester Trucks.
