How to Interpret a Chevy Truck VINby David Curtis
Your truck's vehicle identification number contains clues to a variety of information, ranging from the country where it was manufactured to its engine size. The specifications for your Chevy truck are detailed in the VIN number, and you can also learn the vehicle's weight rating, its chassis type, the kind of engine and even the city and the plant where it was produced.
The Chevrolet truck's VIN number is on a tag on the driver's side under the windshield molding attached to the dash panel. Older models have a tag attached to the firewall or door jam. It can also be found on the vehicle's certificate of title.
The first character will indicate where the truck was manufactured. The number 1 is for the USA, 2 for Canada, 3 for Mexico, J for Japan, K for Korea, S for England, and W for Germany.
The second character cites the manufacturer. The letter G is assigned to a General Motors vehicle.
Learn the division from the third character. Number 1 is for Chevrolet. Other GM codes are 2 for Pontiac, 3 for Oldsmobile, 4 for Buick, 6 for Cadillac, and 8 for Saturn.
Gross Vehicle Weight Rating, or GVWR, is revealed by the fourth character. A is for 0-3000 pounds, B for 3001-4000, C for 4001-5000, D for 5001-6000, E for 6001-7000, F for 7001-8000, G for 8001-9000, H for 9001-10000, J for 10001-14000, K for 140001-16000, L for 16001-19500, and M for 19501-26000.

Identify the body type through the seventh character. The number 3 is for a four-door cab, 4 for a two-door cab, 6 for a Suburban, 7 for a Motor Home chassis, 8 for a two-door sport utility, 9 for an extended cab, and 0 for a chassis only.
Find the type of engine used with the eighth character. Engine combinations vary for each model and year. Some of the more popular truck engine codes are C for a 6.2 diesel, F for 5.0 gasoline engine, R for a 5.7, and W for a 4.3.
