KAX Radiator for Grand Cherokee and Durango - Durable Replacement

Our review of the KAX radiator examines whether this replacement cooling unit is a practical choice for owners of several Grand Cherokee and Durango V6 and V8 models. The bottom line: this radiator is aimed at drivers who need a direct-fit, reasonably priced replacement that uses an aluminum core and plastic tanks for reliable heat dissipation; the main reason to buy is fitment coverage for multiple model years and an included two-year warranty that provides peace of mind during installation and early ownership.

Key Features

• Fitment: Compatible with a broad range of Grand Cherokee and Durango model years so owners can find a direct replacement without complex modifications.
• Construction: Aluminum core with high-grade plastic water tanks offers good thermal conductivity while resisting corrosion compared with all-plastic designs.
• Leakproof testing: Each radiator undergoes leak testing before shipment to reduce the chance of early failure and coolant loss.
• Shipping protection: Foam-corner packaging reduces deformation and transit damage, helping the part arrive ready to install.
• Warranty: A two-year warranty covers early defects and gives added assurance after purchase.

Who It's For

This radiator is best for DIY mechanics and independent shops replacing a failed or leaking radiator on compatible Grand Cherokee and Durango models, particularly those with 3.6L, 5.7L, or 6.4L engines across the listed years. The direct-fit approach streamlines replacement and lowers install time for people who prefer to swap the core without sourcing multiple aftermarket adapters.

Owners who need OE-level cosmetic finish or those replacing other cooling components at the same time should compare options; buyers seeking a factory-branded original part or a different material construction may want to evaluate OEM sources or performance-specific radiators before committing.
