Detroit Diesel Engines: How to locate your Detroit Diesel Unit Number (Serial Number)
Detroit Diesel engine serial number can be found in two places:
When quoting a customer on an engine, we always need an engine serial number. This information ensures that the replacement engine will be an exact fit for the piece of equipment or truck, so you don’t have to worry!
Serial numbers are hard to find, especially after the engine has been in use and has a build-up of dirt and grease.
You can find your engine serial number on the engine date plate and stamped into the block.
Can’t find the tag on the valve cover?
This video shows where Detroit Diesel generally places serial numbers on the engine block. If you have a different model engine, it might be in a slightly different place. Use this video for a general idea of what to look for on the engine block.
