This 2003 Chevrolet Suburban had an issue with the Low Coolant warning coming on. A quick inspection found evidence of leaking on the plastic tank on the driver's side of the radiator. This video walks you step by step through removing and replacing the radiator in this year range of Chevrolet 1/2 ton full sized trucks.
One difference you might note is that your vehicle may have electric cooling fans rather than the mechanical fan this truck had. If you have electric cooling fans, there will be 2 connections to disconnect near the center bottom of the fan assembly. It will bolt into the same location that the fan shroud bolted into in this video and pull up and out of locator tabs at the bottom to remove it from the vehicle.
This radiator does not include an engine oil cooler as the vehicle is not equipped with one. The Core Width was 34". On your vehicle, if you do not know of you have an oil cooler or not, check the plastic tank on the driver's side. If there are lines connected to fittings at the top and bottom directly below the upper radiator hose connection, then your vehicle has an engine oil cooler. If you're under the vehicle, check the oil pan where the oil filter attaches. Above the oil filter is where cooler lines will attach if your truck has it. You will either have Oil Cooler lines, or a cover/plug that's a few inches long in that location.
Thank you for checking out the video, and I'll include links to a few other videos for this same vehicle that might also apply to your vehicle.
