Where Do I Find My Caterpillar ESN?

Most engine serial numbers can be found on the dataplate, which is typically on the driver side of the valve cover. Not all engines are consistent in where they put these information plates. The dataplates for a certain type of engine can be found in various places depending on the model. However, Caterpillar is pretty regular with their location.

If you're looking for more information on ESNs in general, we have a blog about other diesel engine serial numbers!

What's the Format of a Caterpillar Engine Serial Number?

Its a little hard to find something when you dont know what youre looking for. We get people that try to give us part numbers, casting numbers, or even VINs instead of ESNs, simply because they dont know what an engine serial number should look like.

All Caterpillar ESNs have a similar format, which makes them pretty easy to identify. They all begin with a three number/letter prefix, which is then followed by 7 digits.

The prefixes will correspond to a particular model, and usually to a certain subsets of the model. For the more popular prefixes, people will sometimes refer to their engine by the prefix rather than the broader 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 even have reputations. 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 criticized.

LOCATE YOUR CATERPILLAR ENGINE SERIAL NUMBER

When looking to buy a replacement engine for your piece of equipment, it is important to know the serial number of your current engine. This information can be found on the engine data plate, located on the left side by the injection pump. Engine serial numbers are also stamped on the engine block.

The serial number is usually 8 digits long. Pictured: engine data plate with a serial number of MSX81323.

Write down the numbers or take a picture of the data plate and give us a call. A Diesel Engine Specialist will be able to verify whether we can supply a new engine, re-manufactured or both.

This is not your engine serial number!

We need your engine number and this tag does not give us enough information to find your replacement engine. This is the EPA tag.

Can’t find the tag on the valve cover?
