KAX CU2951 Engine Radiator Replacement - Direct Fit Cooling

Our review of the KAX CU2951 engine radiator replacement finds it best suited for owners of mid-2000s to early-2010s compact SUVs and sedans who need a dependable direct-fit cooling core. The bottom line: this radiator is a practical replacement for specific Patriot, Compass, Avenger, 200, Caliber and Sebring model years because it mirrors original equipment dimensions and uses an aluminum core with high-density fins for efficient heat dissipation. Professionals will appreciate the factory-style fit and tested construction, while DIYers will value the clear OE cross-reference numbers.

Key Features

• Direct fit compatibility: Built to match the original radiator dimensions and OEM cross-reference numbers so installation aligns with the listed Patriot, Compass, Avenger, 200, Caliber and Sebring years.
• OE numbers and specs: Supplied with OEM part references and concrete dimensions so buyers can confirm fit using vehicle fitment tools before ordering.
• High-density multi-louver fins: Larger heat dissipation area promotes improved cooling efficiency under normal driving and light towing conditions.
• Aluminum core with plastic tanks: Aluminum core provides good thermal conductivity while plastic water tanks reduce weight and resist corrosion in typical use.
• Factory testing and quality control: Each radiator undergoes leak, pressure, aging and durability tests and is produced under an IATF16949-aligned process for consistency.
• Upgraded packaging: Reinforced shockproof packaging with foam and bubble protection reduces shipping damage risk and helps ensure safe delivery.

Who It's For

The KAX CU2951 is aimed at owners of 2007-2016 Patriot and Compass, 2008-2014 Avenger, 2011-2014 200, 2007-2012 Caliber and 2007-2010 Sebring who need a like-for-like replacement radiator that closely matches original dimensions and OE references. It suits repair shops and experienced DIY mechanics who will install a unit that requires minimal modification.

This radiator is not the right choice for vehicles outside the listed model years or for custom cooling upgrades that require larger cores or performance-enhancing features beyond OE-equivalent design. Buyers seeking welded all-aluminum tanks or motorsport-grade cooling should look at specialized performance radiators instead.
