To find the exact towing capacity for *your* specific 2002 Chevy Express 1500, you should:
* Check the sticker: Look for the sticker on the driver's side doorjamb or inside the glove compartment. This sticker will list the vehicle's specifications, including towing capacity.
* Consult your owner's manual: The owner's manual will also provide the towing capacity information specific to your van's configuration.
Without knowing your van's specific configuration, I cannot give you a definitive answer. However, you can expect the towing capacity to be between 4,500 and 6,000 pounds, but again, this is just a general range and may not be accurate for your vehicle. Always check the documentation on your specific van.
