How to Replace a Fan Clutch in a 1996 Jeep 4.0L

The mechanical, engine-driven cooling fan on the 1996 Jeep Cherokee uses a viscous fluid clutch mechanism. The clutch allows the fan to rotate differently depending on the cooling needs of the engine. When the engine is cool, the fan can turn slower than the engine and thus conserve fuel. As engine temperature increases, so does the fan speed enabling the fan to provide greater engine cooling when needed. A seized fan clutch may cause excessive fuel consumption and slow engine warm-up. A fan clutch that has lost fluid and doesn't engage may cause engine overheating. Fan clutch replacement does not require any specialized tools.
