Description

This 2004-2007 Buick Rainier 4.2L 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 2004-2007 Buick Rainier 4.2L Replacement Radiator 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.
