These 2003 new fangled contraptions. Radiator caps are a thing of the past. Now we have radiator reservoir caps. Neat...

Between the front grill and the radiator.
Should be a removable housing at the engine end of the upper radiator hose
The 2004 GMC radiator drain is located on the bottom of the radiator. The radiator drain plug can be removed with a half inch ratchet.
1994 to 2003 but dont quote me on it 1994- 2004 same body but diff radiator support 1982-1993 gmc s15 has same chassis 1994-2004 same body style exp. extreme may need to swap out radiator support
The later models (2003 (I think) on) do not have a drain cock. The manual says to remove the lower radiator hose at the radiator. Nice touch, GM!
The radiator drain plug for a 2003 GMC Sonoma truck is typically located at the bottom of the radiator on the driver's side. It may appear as a small plastic or metal plug that can be turned by hand or with a tool. To drain the coolant, ensure the engine is cool, then open the drain plug to allow the coolant to flow out into a container. Always remember to properly dispose of the coolant afterward.
