KAX CU2988 Radiator Compatible with Maxima and Altima - Durable

In this review the KAX CU2988 radiator is evaluated for drivers who need a direct replacement for specific Nissan Maxima and Altima models. The bottom line: this radiator is aimed at owners seeking a corrosion-resistant, leak-tested replacement that matches original fitment, and the single biggest reason to buy is its combination of an aluminum core and high-grade plastic tanks that promise improved thermal conductivity and long service life. The review focuses on compatibility, build quality, packaging, and the seller support that backs the part.

Key Features

• Vehicle fitment: Designed to directly replace radiators on compatible 2009-2014 and 2016-2023 Maxima and 2007-2018 Altima models, reducing installation guesswork.
• OEM part numbers: Matches multiple factory numbers including CU2988, 21410JA00A and related codes, which helps confirm correct application for many common engine configurations.
• Durable construction: Uses a high-grade plastic water tank and an aluminum core to resist corrosion while maintaining strong thermal transfer for engine cooling.
• Leakproof testing: Each radiator is tested for leaks before shipping to help avoid early failures and ensure dependable operation out of the box.
• Protective packaging: Packaged with foam in all four corners and shockproof materials to minimize the risk of transit damage and deformation on delivery.
• Customer support and warranty: Backed by a one year warranty and manufacturer support for fitment and aftercare questions, providing added peace of mind.

Who It's For

The KAX CU2988 is best suited to owners of the listed Nissan Maxima and Altima model years who want a like-for-like replacement radiator built from an aluminum core and plastic tanks. It appeals to DIY installers and independent shops that prioritize parts matching OEM numbers for straightforward swaps and reduced modification.

It is less appropriate for vehicles outside the specified model years or for customers who require a performance aftermarket or high-capacity racing radiator; those buyers should look for specialized performance units rather than a direct OEM-compatible replacement.

Pros & Cons

Pros

• Aluminum core with plastic tanks provides effective thermal conductivity and reasonable corrosion resistance for standard driving conditions.
• Leakproof testing performed prior to shipment reduces the chance of receiving a defective unit.
• Protective foam and shockproof packaging lower the risk of transit damage and deformation.
• One year warranty and manufacturer support help address fitment or early-failure concerns.

Cons

• Compatibility is limited to the listed Maxima and Altima years, so confirming vehicle fitment is required before purchase.
• Not a performance or heavy-duty upgrade; buyers needing higher cooling capacity should consider aftermarket performance radiators.
