Chevrolet provides identification numbers on its engines. Car owners can interpret the individual letters and numbers of an engine identification code to learn more about the vehicle.
Chevrolet engine identification codes consist of eight characters. The first character indicates the manufacturing plant, the following four indicate the date of manufacture. The final three characters make up the engine suffix code and indicate the exact model of the engine.
There are seven plant codes for Chevy engines. The codes F, H, K, M and S stand for Flint motor, Hydramatic, Ontario, Mexico and Saginaw plants, respectively. T stands for the Tonawanda plant, and V stands for the Flint engine plant. The following two characters indicate the month, and the next two indicate the year the engine was produced in. The last three characters are unique to the engine model.
