Performance Radiator for Lexus LX (1996-1997) 4.5L Automatic

Heavy-Duty 3-Row Aluminum Performance Radiator for 1996-1997 Lexus LX

Direct Thermal Upgrade: Replaces the age-fatigued OEM radiator with a full aircraft-grade aluminum unit to eliminate overheating under heavy off-road and towing loads.

The Stock LX FZJ80 Thermal Weakness

The factory cooling system on the 1FZ-FE utilizes crimped composite end tanks that embrittle after decades of thermal cycling, causing seam separation and sudden pressure loss. Additionally, the stock core density struggles with low-airflow heat soak during technical trail crawling, high-ambient desert operation, and sustained heavy towing.

The Engineering Solution

Constructed from 100% TIG-welded T-6061 aluminum, this downflow unit features a high-density 3-row racing tube core measuring 16.75 in H x 28.65 in W. Eliminating failure-prone plastic tanks and rubber gaskets, it maximizes fluid volume and thermal transfer efficiency. It integrates an internal transmission oil cooler with M14x1.5 threaded ports to stabilize A343F gearbox temperatures under continuous load.
