Aluminum Radiator for Nissan Altima Maxima (2002-2006) 3.5L

Direct-Fit Aluminum Radiator for 2002-2006 Nissan Altima,Maxima

What it Does: The Aluminum Radiator replaces the failure-prone factory heat exchanger on the 2002-2006 Nissan Altima and Maxima to maximize thermal dissipation and prevent catastrophic overheating.

The Stock Nissan Altima,Maxima Cooling Failure Points

The OEM cooling assembly on the L31 Altima and A34 Maxima relies on crimped plastic end tanks bonded to a thin single-row aluminum core. Over repeated thermal cycles, the factory glass-filled nylon tanks degrade, embrittle, and develop micro-fractures along the crimp seam. Under high-load conditions, the VQ35DE platform generates high coolant pressures that blow past aged rubber tank gaskets or snap fragile upper inlet necks, causing sudden coolant dumps, head gasket failure, and severe cylinder head warpage.

The Engineering Solution

This dual-row, high-capacity all-aluminum radiator eliminates structural failure points by utilizing 100% TIG-welded aircraft-grade aluminum end tanks and a precision furnace-brazed core. Designed as a direct bolt-in unit referencing DPI CU2415 and OEM specification RD-933-318-G4, the design significantly increases fluid capacity and convective heat transfer surface area. The dense louvered multi-fin design promotes aggressive laminar airflow across the internal cooling tubes, effectively rejecting heat soak and ensuring sustained optimal operating temperatures under severe driving loads.
