What is the towing capacity of a 1990 Chevy suburban 2500 with 6.2 L diesel V8 4 x 4?

The exact towing capacity for a 1990 Chevy Suburban 2500 with a 6.2L diesel V8 and 4x4 depends on several factors including the specific options and configuration of the individual vehicle (like axle ratio, transmission type and options packages). There wasn't a standardized published number across all trims.

However, a reasonable *estimate* for the towing capacity would be in the range of 6,000 to 8,000 lbs. This is just an approximation. To find the precise towing capacity for *your specific* 1990 Suburban 2500, you should:

* Check the owner's manual: This is the most reliable source. The sticker inside the driver's side doorjamb might also list the information.

* Look for a sticker on the vehicle: Often, there's a sticker on the vehicle, usually near the driver's side doorjamb or the glove compartment, specifying the towing capacity.

* Consult a GM parts or service department: They may be able to look up information based on the VIN.

Remember that even with the correct towing capacity, other factors like terrain, load distribution, and braking capacity significantly impact safe towing. Always ensure your vehicle is properly equipped for the weight you intend to tow.
