This 1999-2006 GMC Sierra 1500 4.8L/5.3L radiator is a direct OEM replacement for your old stock unit. There is no need to bend, cut, or modify anything to ensure a proper fitment in your vehicle. This radiator features OEM spec plastic end tanks attached to an aluminum core for stock cooling efficiency. At some point the inevitable happens to original stock radiators. They either spring a leak, get clogged up, or a plastic inlet or outlet cracks due to years of constant clamp pressure. This GMC Sierra 1500 radiator is a perfect replacement to keep your cooling system in top notch shape, and just like all Mishimoto parts, comes with the Mishimoto Lifetime Warranty.
