Aluminum Radiator for Jeep Cherokee (1984-1990) 2.1L 2.5L 2.8L 4.0L

Direct-Fit All-Aluminum 3-Row Radiator for 1984-1990 Jeep Cherokee XJ

Thermal Management Upgrade: Replaces failure-prone factory radiators with a heavy-duty, all-aluminum 3-row cooling core engineered to eliminate heat soak during low-speed trail crawling and heavy-load operation.

The Stock Cherokee Thermal Bottleneck

Factory 1984-1990 XJ cooling systems rely on restrictive thin-core designs with plastic or crimped end tanks that degrade under continuous heat cycles. The cramped XJ engine bay severely restricts convective airflow, leading to rapid coolant temperature spikes when idling or traversing off-road obstacles. Over time, OEM tank seams fatigue, causing structural cracking, coolant depressurization, and catastrophic engine overheating on inline and V6 powerplants.

The Engineering Solution

Constructed entirely from aircraft-grade AA5052 aluminum, this radiator features fully TIG-welded end tanks to eliminate mechanical crimp failures. The 3-row core measures 30.91" x 10.95" x 2.00", drastically increasing surface contact area and fluid volume for accelerated heat rejection. Equipped with a 1.25" inlet, 1.50" outlet, precision billet filler neck with cap, and an integrated internal transmission oil cooler, it provides direct-fit thermal stabilization for both automatic and manual setups.
