Where is the radiator drain plug on a 2003 Express Chevy van 3500 located?

The radiator drain plug location on a 2003 Chevy Express 3500 van is at the bottom of the radiator, usually on the driver's side. However, it's not always easy to see without getting down low and possibly using a flashlight. It's a small plug, often with a slightly recessed head.

To be certain:

* Consult your owner's manual: This is the best resource for the exact location. The manual will have diagrams.

* Look closely at the bottom of the radiator: Once you're underneath the van, scan the entire bottom of the radiator. The plug is typically towards the lower center or slightly to one side.

* Check online forums: Search online forums specific to the 2003 Chevy Express 3500. Owners often post photos or detailed descriptions of the location.

Caution: When draining the radiator, be sure to have a suitable container to catch the coolant. Coolant is toxic and should be disposed of properly. Let the engine cool completely before attempting to drain the radiator.
