To replace the cooling fan, the negative terminal of the battery should be disconnected and the vehicle securely supported. The lower splash pan, radiator support cover, air filter housing, and torque strut (if equipped) should be removed. The coolant should be drained and the upper radiator hose and upper transaxle oil cooler line should be disconnected. If there is an oil cooler, the retaining bolt should be removed and the oil cooler lines disconnected. The fan electrical connectors and wiring harness should be disconnected, and the fan(s) lower mounting bolts should be removed. The fan(s) can then be unbolted from the radiator and carefully lifted out of the engine compartment. To detach the fan from the motor, the motor shaft nut should be removed, and to detach the fan motor from the shroud, the mounting bolts should be removed. Installation is the reverse of removal, and the cooling system should be refilled, the engine run, and checked for leaks and proper operation.
