Mishimoto Fan Shroud for Jeep Cherokee XJ 4.0L 1989-2001 (Silver)

The cooling system of your 1989–2001 Jeep Cherokee XJ 4.0L faces significant challenges when traversing steep rock faces, muddy hills, or narrow trails. The stock fan system, relying on engine power, is outdated and imposes considerable weight and aerodynamic drag on the vehicle. This not only drains engine horsepower and torque but also limits cooling efficiency since airflow is directly tied to engine speed. At lower engine speeds, the fan moves less air, reducing radiator cooling.

To address these issues, Mishimoto introduces a revolutionary solution in the form of an electric fan shroud equipped with three high-flow 10” slim fans. Unlike traditional fans, each Mishimoto fan operates independently of engine RPM, ensuring a consistent 950 CFM airflow rate at all times. One fan replaces the stock A/C fan, while the other two enhance radiator cooling. For 1997-2001 models, an included A/C fan jumper harness ensures seamless integration with the vehicle's air conditioning system.

Constructed from lightweight aluminum, the Mishimoto fan shroud covers a larger area of the radiator compared to the stock shroud, thereby optimizing airflow across the entire radiator surface. In comparative tests, the Mishimoto XJ Fan shroud demonstrated a 41.9% improvement in airflow over the stock shroud at idle and a 22% improvement at 2,500 RPM, ensuring superior cooling performance in demanding conditions.

Moreover, by replacing the mechanical fan, the Mishimoto electric fan setup reduces engine drag, freeing up additional horsepower and torque for enhanced off-road performance. Users have the flexibility to manually activate the fans using a separate switch or utilize the adjustable fan controller, which mounts conveniently on the Mishimoto fan shroud. The controller allows customization of fan activation temperatures ranging from 150°F to 240°F, ensuring optimal cooling efficiency under various operating conditions.

The comprehensive kit includes all necessary components for installation, such as a wiring harness, push-in radiator probe temperature sensor, and in-line NPT temperature sensor. Backed by Mishimoto's Lifetime Warranty, this performance aluminum fan shroud guarantees durability and long-term reliability, specifically designed as a direct-fit for 1989–2001 Jeep Cherokee XJ models equipped with the 4.0L engine.

In summary, Mishimoto's innovative electric fan shroud not only enhances cooling efficiency by significantly increasing airflow but also contributes to vehicle performance by eliminating the drawbacks associated with traditional mechanical fans. Whether navigating challenging terrains or in everyday driving, this upgrade promises consistent and effective engine cooling, backed by Mishimoto's commitment to quality and durability.
