Product Description

The Mishimoto MMRAD-G8-08 performance radiator is a direct replacement for 2008-2009 Pontiac G8 models equipped with the 6.0L/6.2L V8 (L76, L77, L98) on the VE (Commodore) platform. Crafted with a durable 2-row, 56 mm-thick all-aluminum core and TIG-welded tanks, the design boosts cooling volume by 39% versus the factory radiator - perfect for spirited street driving, towing, or track days.

Installation is straightforward using existing OE mounts and requires no modifications. The 19 PSI cap raises coolant boiling point for added safety under high-load conditions, while the magnetic drain plug helps protect the engine from metal debris. Despite being untested on GXP models or late-2009.5 builds, RWD Base, GT, and GXP trims have been confirmed to fit with slight coolant-line shaping. Backed by Mishimoto's lifetime warranty, this radiator offers reliable, long-lasting performance improvement.
