Very important remark: The engine prefix (first three figures and numbers in serial number) is absolutely necessary information for correct engine identification. But your additional information (full serial number, arrangement number, where the engine is installed etc.) will help to avoid mistakes and save our and your time. Knowing your engine serial number will enable you to decide on the exact parts you require when you need to service or repair your engine. Your serial number is located on your engine plate, often located on the left-hand side of the engine. Typically the first letters and numbers will identify the engine, for example, DJ51279, to find all the.
Have you ever thought much about your ESN or why you might need to know it? Diesel engine serial numbers are vital to ensuring you're getting the right fit for your engine.
Engine serial numbers are specific numbers assigned to every individual engine. No engine that exists has the same serial number as another engine. If you know your engine serial number, you can find out the exact parts your engine was built with when it was first made.
This post will take you through some of the most popular diesel engine brands and where their engine serial numbers are located.

Caterpillar Engine Serial Number Location
Most engine serial numbers can be found on the dataplate. As you'll see later in this article, the dataplates for a certain type of engine can be found in various places depending on the model. However, Caterpillar is pretty consistent, and the dataplate on a Caterpillar engine can be found on the driver's side of the valve cover.
Caterpillar Engine Serial Number Identification
All Caterpillar ESNs have a similar format. They all begin with a three number/letter prefix, followed by 7 digits. The prefixes will correspond to a particular model. For example, prefixes of 1LW, 2WS, 5DS, 5EK, and 6TS indicate that the engine is a 3406E. For the more popular prefixes, people will refer to their engine by the prefix rather than the model. You may have heard someone say, 'Oh, yeah, my 6NZ runs like a champ.' A 6NZ is a common prefix for a single-turbo C15. Some prefixes' reputations precede them. For example, a C15 with a prefix of MBN is known as a 'Bridge motor' (because it was the bridge engine from the mechanical C15 to the electronic C15 ACERT), and is often heavily critiqued.

Cummins Engine Serial Number Location
Cummins engine will have the engine serial number on the dataplate; however, the dataplate will be in different locations based on the model of the engine. You can find the location of your dataplate in your owner's manual, but if you haven't held on to the physical copy of the manual, then you can accessCummins Quickserve and get 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? It's okay. Cummins also stamps the engine serial number into the passenger side of the engine block for all models.

Cummins engine serial numbers look more like a classic serial number than Caterpillar ESNs do. They are composed only of 8 numbers. They're in a specific numerical sequence, based on which engine came off the assembly line first. There is no special designation for particular models.
Cummins engines do have something a little unique, called a CPL. This stands for Critical Parts List and, as you can probably guess, is a list of the critical parts of the engine. There are fewer CPLs than ESNs because multiple engines can have the same CPLs. For most major parts of an engine, you can give us a CPL rather than an ESN.
Detroit Diesel Engine Serial Number Location
We could (and did) write an entire blog on where you can find your Detroit Diesel engine serial number. Detroit is notoriously inconsistent when it comes to ESN placement. While the locations you can find your ESN are often consistent across a model, they aren't always, so don't panic if you go to look in the spot listed below and don't find it. It'll be on the engine somewhere, so just keep looking.
- Detroit Diesel Series Inline 53:stamped in the upper rear corner of the right side of the block
- Detroit Diesel Series V53:stamped in the upper right corner of the front of the block
- Detroit Diesel Series 60:on an option plate with the information located on the left side of the valve cover
- Detroit Diesel Series Inline 71:printed on the option label, which is attached to the valve cover
- Detroit Diesel Series V71:stamped into the block in either the left side, upper front corner, or the right side, upper rear corner
- Detroit Diesel Series V92:stamped on the front side, on either the upper front or upper rear corners
- Detroit Diesel Series 149:stamped on the rocker cover rail towards the rear
Detroit Diesel Engine Serial Number Identification
Thankfully, the format of Detroit engine serial numbers is more consistent than their location. It can still get rather complicated though. For the sake of keeping this guide simple, were just going to go over the highlights.
- Detroit Diesel Series Inline 53:ESNs begin with 04D and can be found under the model numbers, which begin with 504.
- Detroit Diesel Series V53:ESNs begin with a 06D and the model numbers begin with 506.
- Detroit Diesel Series 60:ESNs begin with 06R and model numbers begin with 606.
- Detroit Diesel Series Inline 71:ESNs begin with 06A and will be near the model numbers, which begin with 106.
- Detroit Diesel Series V71:ESNs begin with 08VA and model numbers begin with 708.
- Detroit Diesel Series V92:ESNs begin with 08VF and model numbers begin with 808.
- Detroit Diesel Series 149:ESNs start with 12E and model numbers that start with 912.
Navistar Engine Serial Number Location
Navistar actually keeps the ESN location pretty simple. The engine serial number for Navistar engines can be found stamped on a pad on the block. For engines pre-2000 engines, that pad can be found on the left side of the block, just under the head to block parting line. For engines newer than that, the pad is on the right side of the block, between the oil cooler and the top of the block.
For most Navistar engines that were built after 1993, you'll need more than just the engine serial number as well. You will also need the engine model, model year, horsepower rating, and torque rating, which can all be found on the emission label. The emission label can be found on the top of the rocker cover or intake manifold.
Navistar Engine Serial Number Identification
Navistar engine serial numbers are probably the most informative of all the ESNs for the major OEMs. They have a specific format that will provide the engine model, configuration, application, country of origin, and unit number.
- The first three (or four, in some cases) digits indicate the engine model.For example, 466 or 570H.
- The letter after the engine model indicates the configuration; B is for turbo JWAC, D is for naturally aspirated, G is for turbo air to air, H is for HEUI, and T is for turbo engines.
- The next number and letter combination indicates the application; A2 means a service vehicle and M2 means a truck.
- The next letter will be the same for all, and is a U, which indicates that the country of origin is the United States.
- The last seven digits indicate the unit number, which is the part that will be different for each different engine.
The Importance of Diesel Engine Serial Numbers
Long, long ago in a time before electric cars were even conceived, heavy duty diesel engines were first made. These engines were not like mass-produced automotive vehicle engines. There was no standard Make-Model-Year formula that magically gave all engines with the same model name the exact same parts. No, they were special; each individual engine was different as it came down the conveyor belt.
And apparently the manufacturers didn't think about what a pain it would be in the future when you need to order parts for repairs.
Because of the lack of foresight, finding parts that correctly fit an engine can be incredibly complicated. Engine serial numbers are important because they are the only guaranteed way to find the exact parts that an engine was built with. Usually, if you're buying a single part, providing the part number off the old part will also work. However, if you're looking to get an engine rebuild kit, we will always ask you for an engine serial number. This might seem excessive, but when it comes to an expensive kit with a lot of parts, we want to make sure you're getting the right thing. So, whether you're calling us or using ouronline quoting tool, be sure to provide your engine serial number.
When calling to order parts, we get some people that want to give us VINs (Vehicle Identification Numbers) instead of ESNs. Unfortunately,a VIN is different from an ESN. We are able to look up some VINs to find their coordinating ESNs, but this is not a guarantee. Depending on your vehicle, you can always use ourVIN Decoder Resource Guide.
