Performance Radiator for Nissan Frontier (2005-2018) 4.0L Automatic

Heavy-Duty All-Aluminum Performance Radiator for 2005-2018 Nissan Frontier

Direct-fit replacement engineered to eliminate catastrophic internal fluid contamination and deliver superior thermal rejection under severe towing and off-road conditions.

The Stock Frontier SMOD & Thermal Vulnerability

Factory D40 Frontier radiators utilize crimped plastic end tanks bonded to an aluminum core, which become brittle over repeated thermal cycles. More critically, the OEM internal transmission oil cooler is prone to internal rupture. This cross-contaminates automatic transmission fluid with engine coolant—a catastrophic failure mode known across the platform as the "Strawberry Milkshake of Death" (SMOD) that destroys the RE5R05A transmission. Furthermore, the stock core fin density struggles to shed heat effectively during sustained uphill hauling or high-load low-speed trail crawling.

The Engineering Solution

This performance unit replaces failure-prone plastic with 100% TIG-welded, aircraft-grade aluminum end tanks and a precision brazed core. Eliminating crimped resin tanks permanently removes end-tank seam separation and internal cooler breach risks. High-efficiency multi-louvered fins increase surface area contact, accelerating heat dissipation across the VQ40DE cooling circuit while maintaining exact drop-in fitment with factory fan shrouds, hoses, and mounting brackets.
