Description
The Mishimoto MMFS-XJ-89BK is a purpose-built performance aluminum fan shroud engineered specifically for the 1989-2001 Jeep Cherokee XJ 4.0L. Instead of relying on the stock engine-driven fan that saps horsepower and only moves air in proportion to engine speed, this shroud houses three Mishimoto high-flow 10-inch electric slim fans, each capable of a constant 950 CFM regardless of how fast the engine is turning. This black powder-coated shroud is the without-fan-controller configuration, giving XJ owners a straightforward, direct-fit upgrade to their cooling system.
By eliminating the heavy mechanical fan, this Mishimoto cooling upgrade reduces rotating mass and frees up power that would otherwise be spent spinning the stock fan. One of the three electric fans replaces the stock A/C fan, while the remaining two are dedicated to cooling the radiator, and the lightweight aluminum shroud itself covers more of the radiator core than the factory shroud so the entire radiator benefits from the increased airflow. In Mishimoto’s own testing, this fan shroud moved air 41.9% better than the stock fan shroud at idle and 22% better than the stock fans at 2,500 RPM, translating directly into more consistent cooling whether you’re crawling rocks at low speed or cruising the highway.
Vehicle Applications
This fan shroud is a specific fit for the 1989-2001 Jeep Cherokee XJ 4.0L and covers a wide span of XJ trims across those model years. It fits the Cherokee Base (1989-1994), Briarwood (1991-1992), Laredo (1989-1992), and Pioneer (1989-1990), along with the Limited (1989-1992 and 1998-2001), Country (1993-1997), Classic (1996 and 1998-2001), SE (1994-2001), and Sport (1989-2001). An included A/C fan jumper harness ensures proper A/C function specifically on 1997-2001 models, and the shroud is compatible with both the stock radiator and the Mishimoto radiator.
