Performance Radiator for Land Rover Range Rover (1996-1998) 3.9L 4.0L Automatic

High-Efficiency All-Aluminum Radiator for 1996-1998 Land Rover Range Rover

Primary Function: Direct-fit, multi-core cooling upgrade engineered to replace failure-prone OEM plastic-tank units and eliminate thermal degradation on Rover V8 drivetrains under heavy off-road and towing loads.

The Stock Range Rover Thermal Weakness

Factory Range Rover cooling systems rely on composite plastic end-tanks crimped to an aluminum core with rubber gaskets. Over repeated thermal cycles, the Rover V8 engine induces significant heat stress, causing the plastic tanks to embrittle, craze, and warp. This leads to blown end-tank seams, critical coolant loss, and severe cylinder head warpage or slipped cylinder liners—common failure modes directly tied to overheating in high-mileage GEMS engines.

The Engineering Solution

This high-efficiency replacement features a heavy-duty 3-row crossflow core manufactured from AA5052 aircraft-grade aluminum with 2 mm hand-formed tanks. Vacuum brazing and 100% TIG welding eliminate crimped seams and leak-prone plastic components entirely. With a high-density 14–16 fins-per-inch pitch and 3/8-inch row spacing, thermal dissipation is maximized across the 15.18 x 27.17-inch core. An integrated M12x1.5 / 3/8-18 NPT transmission oil cooler ensures optimal fluid temperatures for ZF automatic transmissions during sustained low-range operation.
