Mishimoto Pontiac G8 Performance Aluminum Radiator 2008-2009

The 2008-2009 Pontiac G8 V8 packs a lot of heat into a thin plastic-tank radiator. This Mishimoto performance aluminum radiator uses a 2.2-inch two-row core and TIG-welded aluminum tanks for Base, GT and GXP cars.

Two-row cooling for the G8 V8

Core volume rises about 39 percent versus stock with a 56mm-thick core that supports street, back-road and track use on L76/L77 and LSA powertrains. Polished aluminum finish and a direct bolt-in layout keep the swap straightforward. AutoTalent lists this Mishimoto performance aluminum radiator with verified US-market fitment for the vehicles in the table below. Installation is a direct-fit job for the listed chassis when you follow Mishimoto's application guide. Keep factory coolers, sensors and fasteners in good condition when the instructions call for reuse, and torque every clamp and fastener to the published spec. If you are stacking supporting mods—intake, tune, larger turbo or track-day heat—confirm hose routing and cooler clearance before the first hard pull. US shipping dimensions and weight above are for the boxed kit so you can plan freight.
