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
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.
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 air bag sensors for a 2004 GMC are located on the bottom of the radiator support. They can be accessed by removing the front bumper and looking up under the vehicle.
