CU2727 Replacement Radiator for Aura G6 Malibu - Durable Cooling

In this review of the CU2727 replacement radiator, the bottom line is straightforward: it is a practical, budget-friendly option for owners of the Aura 2007-2008 3.5L, G6 2005-2010, and Malibu 2004-2010 3.5L who need a like-for-like cooling part. The reviewer found it suits installers who want an aluminum-core radiator with a plastic water tank that mirrors original fitment, and the unit's shockproof packaging and leak testing provide confidence during shipping and first use. For those prioritizing an exact OEM-quality finish, this is a capable aftermarket choice.

Key Features

• Vehicle Fitment: Designed specifically for Aura 2007-2008 3.5L, G6 2005-2010 and Malibu 2004-2010 3.5L to simplify replacement and reduce installation guesswork.
• Reference Numbers: Matches common reference numbers CU2727, 15873468, 52494386 and CU2972 to help verify compatibility with service parts lists.
• Shockproof Delivery: Foam secured in four corners and reinforced packaging protect the aluminum core from deformation during transit.
• High Quality Materials: Uses an aluminum core for heat transfer combined with a high-grade plastic water tank to resist corrosion and maintain thermal performance.
• Leak-Tested: Each radiator undergoes leak-proof testing before shipping to reduce early failure risk and ensure immediate usability.
• Customer Support: Backed by a one year warranty and manufacturer support for fitment and post-sale questions.

Who It's For

The CU2727 is aimed at DIY mechanics and independent shops replacing a failed or damaged radiator on compatible Aura, G6 or Malibu models who want a direct-fit, aluminum-core component without factory pricing. It is also a good match for owners who prefer a product that arrives protected by shockproof packaging and has been leak-tested before delivery.

This radiator is less suitable for buyers seeking an OEM-branded part or those requiring exotic performance upgrades; if long-term premium materials or custom cooling improvements are the goal, a higher-end aftermarket or factory unit may be more appropriate.
