    Here's a Do-It-At-Home Method.

    The dealer could also probably tell you but you'd need to tell him which series 1500-2500, etc and which engine.

    Look for the GU or Gt code most of the time will be listed on a tag inside the glove box. GT4=3.73 GU6=3.42. These are two of the most common for later model GM 1500 trucks.
