About the 2020 Chevrolet Silverado 4500HD 5500HD 6500HD
Check the model year on your VIN: on a 2020 vehicle the 10th character of the 17-digit VIN is “L”. Vehicles built for North America always carry the model year in that position; on some European or Australian vehicles it may be left unused, so in that case go by the registration papers or the build plate.
At about 6 years old, a 2020 vehicle is usually past its basic warranty. Typical jobs at this age are brakes, suspension parts, fluids, the 12V battery and diagnosing sensor faults with the factory wiring diagrams.
