Performance Radiator with Shroud for Jeep Wagoneer (1988-1990) 4.0L

High-Efficiency Aluminum Performance Radiator with Shroud for 1988-1990 Jeep Wagoneer

What it Does: The Performance Radiator with Shroud replaces the leak-prone factory cooling assembly on the 1988-1990 Wagoneer to eliminate heat soak, prevent thermal cracking, and stabilize coolant operating temperatures under extreme loads.

The Stock Jeep Wagoneer Cooling Inefficiencies

Factory cooling systems on the XJ-platform Wagoneer rely on stamped plastic end tanks crimped onto an undersized core. Over repeated thermal heat cycles, the factory crimp gaskets dry-rot, crack, and fail under system pressure. Compounding this, the stock clutch-driven fan cannot pull adequate CFM at low engine RPMs, leading to rapid heat soak, vapor lock, and critical overheating in confined AMC 242 engine bays during low-speed crawling or heavy towing.

The Engineering Solution

This cooling upgrade incorporates 100% TIG-welded aircraft-grade aluminum end tanks and a multi-louvered, high-density tube-and-fin core, completely eliminating failure-prone plastic crimps. The precision-engineered aluminum fan shroud focuses suction uniformly across the entire core surface, while the integrated high-output electric fan maintains sustained CFM regardless of engine speed. Engineered as a direct-fit replacement for OEM numbers 52003255, 52003370, and DPI119, it maximizes thermal dissipation and pressure retention in extreme trail environments.

Frequently Asked Questions

Does this fit the XJ Wagoneer?
Yes, this is a direct fit for the 1988-1990 Jeep Wagoneer equipped with the AMC 242 4.0L engine.

Does this upgrade replace the stock mechanical fan clutch?
Yes, the integrated electric fan and matched shroud assembly convert the system to an electric setup, reducing parasitic engine drag and maintaining peak cooling airflow at idle.

The Jeep Durability Standard

Trail-ready reliability requires structural resilience under severe frame torsional flex. Reinforced TIG welds and rigid all-aluminum end tanks protect against internal baffle rupture and seam failure, ensuring constant fluid dynamics through rough off-camber terrain and demanding tow cycles.
