Cummins Engine Serial Number Locations

The easiest way to learn where to find your Cummins ESN is by consulting your owner’s manual. If you don’t have the original manual, have no fear. Cummins makes it relatively easy to find the data you require.

The good news is, you can always identify the engine serial number as well as other vital information such as RPM rating, horsepower and a Critical Parts List (CPL) on the data plate. However, finding the data plate can be difficult because they are frequently located in different positions depending on the model and year.

The following is our list of where to find Cummins ESNs for your particular model to save time and ensure you have the correct information when ordering parts.

Cummins ISB engine serial numbers are commonly found on the rocker cover. In some cases, they are printed on the side of the gear housing.

Cummins ISM engine serial numbers are found on the rocker housing located on the fuel pump side.

Cummins ISX engine serial numbers are conveniently located on top of the rocker level cover.

In the market for replacement parts for your Cummins diesel engine? It's important to know your engine serial number to ensure that you're getting the right fit for your engine.

In this post, we're taking you through where you can locate your ESN on your Cummins applications.

How to Find a Cummins Engine Serial Number

Cummins engines will have the engine serial number on the dataplate. The dataplate on an engine can be a great reference because it will often also include additional information, such as CPL, horsepower, and RPM rating. However, the dataplate can be hard to find, as it will be in different locations based on the model of the engine. The location of the dataplate for your engine will be in your owner's manual. If you've long since lost the physical owners manual, but can accessCummins Quickserve, you can see a digital copy of the owner's manual there.

If you don't have your owner's manual and don't have access to Quickserve, we have the locations for the dataplate on some of the more popular engine models.

  • Cummins ISB:either rocker cover or side of the gear housing
  • Cummins ISC and ISL:top side of the gear housing
  • Cummins ISM:rocker housing, towards the fuel pump side of the engine
  • Cummins ISX:top of the rocker lever cover
  • Cummins QSK45 and QSK60:rear of the engine block

Unable to find the dataplate or don't see your engine model listed above? It's okay. Cummins also stamps the engine serial number into the passenger side of the engine block for all models.

Cummins Engine Serial Number Format

Cummins engine serial numbers look more like a classic serial number thanCaterpillar ESNsdo. Cummins ESNs are eight digits long and are composed only of numbers. They go in a numerical sequence, based on which engine came first off the assembly line. There is no special designation for particular models.

Cummins engines do have something a little unique, called a CPL. CPL stands for Critical Parts List and is a list of the critical parts of the engine. There are fewer CPLs than ESNs because multiple engines can have the same CPLs. When ordering most major parts of an engine, providing a CPL will work just as well as supplying an ESN.

The Importance of Your Cummins Engine Serial Number

We know that finding and identifying your ESN can be a hassle, but knowing your ESN can be crucial when ordering parts for your diesel engine. Giving us part numbers will usually work if you are looking for a single part or two, but we absolutely need an ESN if you are looking for any kind of rebuild kit. If we know an ESN, we can look up all of the exact parts that your engine was built with, and know that were getting you the right stuff.

When you go tosome of our product pages, you will see a box under our price with the available options. One of the fields that appears is for you to input your Engine Serial Number. If you place an order without inputting your ESN for one of these products, you will get a call from us asking for it. We will always do this before processing an order if your ESN is required. We want to send you the wrong parts just as little as you want to get the wrong parts.
