Step 1: Locate the number on the engine block
The serial number of your GM forklift engine will be in a location specific to your model of engine. Below are diagrams showing locations for 2.5/3.0L L-4, 4.3L V-6, small block V-8, and big block V-8 engines, respectively. The big block V-8 engine has two diagrams, indicating serial number location for models both before and after 1991.

Step 2: Interpret the number
Once you have located the serial number, you can derive from it information about your forklift engine. As shown in the diagram below, the first letter indicates the source code of the product. The next four digits indicate the month and day the engine was produced, and the last three digits are the engine’s type code.
More about GM engines
A variety of forklift manufacturers have used GM engines in the past.
• Hyster‘s history with GM engines goes back many years, all the way back to the 2.4 liter engine as well as the 3.0 “iron duke”, and the 350/4.3 engine. When the parent company of Yale, “Nacco” purchased Hyster Company, Yale began using GM engines as well. Recently Nacco has moved away from GM engines to Kubota.
• Toyota uses GM engines as well, believe it or not. The automotive rivals work together somehow as Toyota uses the 4.3L engine. Toyota did use the 3.0 liter engine for a brief period but it no longer does so in 2015.
• Mitsubishi/Caterpillar Forklift uses the GM 4.3 engine in its 8000-12000 pound capacity lift trucks.
