Description
The Mishimoto Performance Aluminum Fan Shroud (MMFS-XJ-89KBK) is a purpose-built replacement for the outdated, engine-driven fan on the 1989-2001 Jeep Cherokee XJ 4.0L. In place of a heavy mechanical fan that only moves air in proportion to engine speed, this black powder coated aluminum shroud houses three Mishimoto high-flow 10-inch electric slim fans that each move a constant 950 CFM no matter how fast the engine is turning. This particular option also includes the Mishimoto adjustable fan controller for on-demand, temperature-based fan activation.
Because cooling performance shouldn’t depend on RPM, this Cooling upgrade lets your Jeep Cherokee XJ 4.0L pull consistent airflow through the radiator whether you’re idling on the trail or climbing at low speed. One of the three fans takes over stock A/C fan duty, while the remaining two are dedicated entirely to radiator cooling. The lightweight aluminum shroud is also sized to cover more of the radiator core than the factory shroud, so a larger portion of the radiator benefits from the added airflow. In Mishimoto’s own testing, this shroud moved 41.9% more air than the stock fan shroud at idle and 22% more at 2,500 RPM, while also removing the drag and rotating mass of the factory mechanical fan.
