Zynrako Aluminum Engine Radiator for Nissan Altima & Maxima 2007–2023 — Integrated Transmission Oil Cooler, Direct-Fit

Zynrako Engine Coolant Radiator is a direct-fit aluminum replacement with an integrated transmission oil cooler engineered for Nissan Altima (2007–2018) and Maxima (2009–2023) automatic-transmission models.

This radiator replaces part numbers such as CU2988, 2988, 21460JA00A and other common OEM references to provide a like-for-like performance upgrade. Built from brazed aluminum with folded-fin edges and thermal expansion slots, the unit is designed to dissipate heat efficiently, resist stress, and integrate into the factory cooling and transmission cooling circuits without modifications. Before ordering, confirm your vehicle year, engine size (2.5L or 3.5L) and transmission type; the Altima 2.5L fit does not cover hybrid variants.

Will this radiator fit my Nissan Altima or Maxima?

Compatibility is specific to model year, engine displacement, and transmission type. This radiator fits Altima 2007–2018 with 2.5L and 3.5L gasoline engines (automatic transmission only) and Maxima 2009–2023 with the 3.5L automatic transmission. Hybrids and manual transmissions are excluded.

• Compatible: Altima (2007–2018) 2.5L & 3.5L automatic; Maxima (2009–2023) 3.5L automatic.
• Not compatible: Altima hybrid variants and models with manual transmissions.
• Cross-references: Replaces CU2988, 2988, 21460JA00A, 21410JA00A, 21410ZN50A, NI3010210.
• Tip: Use vehicle fitment tools or provide VIN for verification before purchase.

What are the construction and cooling performance features?

The core is fabricated from brazed aluminum for strength and thermal conductivity. Folded-fin edges and optimized fin density improve airflow-to-surface contact, while thermal expansion slots reduce stress during temperature cycles. Those design choices promote consistent engine temperature control under daily commuting and highway loads.

• Brazed aluminum core for improved heat transfer and rigidity.
• Folded-fin edges increase fin durability and airflow efficiency.
• Thermal expansion slots minimize stress and extend service life.
• Integrated transmission oil cooler for simultaneous engine and transmission cooling.

How straightforward is installation and what should I prepare?

This is a direct-fit replacement designed to match OE mounting points and hose connections, so installation typically follows factory procedures without custom modifications. Basic tools and replacement coolant are required; allow time to bleed the cooling system and check for leaks after installation. If you’re unsure, a professional mechanic can complete the swap within a few hours.

• Direct-fit: aligns with original mounts and hose fittings for plug-and-play replacement.
• Tools: common hand tools, coolant, hose clamps, and possibly new mounting hardware if original is worn.
• Aftercare: pressure-test, refill coolant, bleed air pockets, and inspect transmission cooler connections.
• Recommended: verify part numbers and vehicle compatibility before ordering.

What maintenance or service life can I expect?

Design elements like brazed joints, corrosion-resistant aluminum, and reinforced fin edges aim to deliver a long service life under normal driving conditions. Regular cooling-system maintenance and using the correct coolant will help preserve performance. Replace if you notice persistent overheating, visible leaks, or bent/damaged fins that restrict airflow.

• Longevity depends on road conditions, coolant maintenance, and installation quality.
• Inspect periodically for leaks, corrosion, or bent fins affecting airflow.
• Use manufacturer-recommended coolant and change intervals to prevent internal corrosion.
• If transmission temperatures rise or external damage appears, service or replace promptly.

Who is this radiator best for? Zynrako’s aluminum radiator with an integrated transmission oil cooler is targeted at owners of Nissan Altima (2007–2018) and Maxima (2009–2023) gasoline models with automatic transmissions who need a reliable, direct-fit replacement that meets common OEM reference numbers. It suits DIY mechanics familiar with cooling-system service as well as shops replacing failed or corroded radiators. Confirm your exact year, engine size and transmission before ordering to ensure a precise fit and avoid returns.
