Performance Radiator for Jeep Grand Cherokee (1993-1998) 4.0L

High-Capacity Aluminum Radiator for 1993-1998 Jeep Grand Cherokee

Replaces the failure-prone factory plastic-tank radiator with a full aluminum 2-row assembly to significantly lower coolant temperatures and prevent overheating under load.

The Stock Grand Cherokee Cooling Weakness

The factory ZJ radiator utilizes a restrictive single-row core crimped to plastic end tanks. Over time, intense thermal cycling degrades the plastic construction, leading to hairline cracks and catastrophic coolant loss at the crimped seams. Furthermore, the limited coolant capacity and narrow surface area of the OEM tube-and-fin design struggle to reject heat effectively. This becomes a critical failure point during low-speed off-road articulation, towing, or steep inclines, resulting in rapid heat soak and potential catastrophic engine damage.

The Engineering Solution

This replacement unit abandons the weak plastic construction in favor of aircraft-grade AA5052 aluminum. Featuring a fully TIG-welded, 2-row brazed core, it substantially increases fluid capacity and maximizes heat dissipation. The core measures 36mm (1.42 inches) thick, dramatically expanding the thermal transfer surface area. Upgraded 2mm thick aluminum end tanks completely eliminate the factory crimp joints, while a CNC-machined billet aluminum filler neck ensures a rugged, leak-free seal. This combination delivers a 35% to 45% improvement in overall cooling efficiency, stabilizing operating temperatures during severe duty cycles.
