To be sure that this is your engine, locate the model number, located on a plate near the top of the engine. The serial number will be an eight digit number that will start with a 5, signifying it is a 53 series engine. The next two digits signify the number of cylinders. For this engine, a model number will always start with 506, and an example of a full model number would be 5063-5200. To determine if you have a turbo engine, or a natural engine, look at the sixth digit. A turbocharged engine will have a 3. For example, 5063-5300 would be a Turbocharged engine.

If you happen to find the serial number instead, it will have a 6D in the number, such as 6D12345. Though it is rare, some Detroit 6V53 engines were made for the Brazilian market, and these have a serial number that starts with DB, such as DB7186.
