Ford 5L8Z-8C607-CB Motor And Fan Assy - Engine Cooling

You can Select Your Vehicle to check if 5L8Z-8C607-CB fits your vehicle.

If the engine is overheating and the cooling fan is not coming on when the engine temperature rises to an excessive level, unplug the fan motor electrical connector(s) and connect the motor directly to the battery with fused jumper wires. If the fan motor doesn't come on, replace the motor. If the radiator fan motor is okay, but it isn't coming on when the engine gets hot, the fan relay might be defective. Locate the fan relays in the engine compartment fuse/relay box. Test the relay. If the relay is okay, check all wiring and connections to the fan motor. If no obvious problems are found, the problem could be the Engine Coolant Temperature (ECT) sensor or the Powertrain Control Module (PCM). Have the cooling fan system and circuit diagnosed by a dealer service department or repair shop with the proper diagnostic equipment. Disconnect the cable from the negative battery terminal. Disconnect the fan motor electrical connector(s). Raise the vehicle and secure it on jackstands. Drain the cooling system. If the coolant is relatively new and still in good condition, save it and reuse it. Remove the hood latch. Remove the upper radiator hose. Loosen the hose clamp by squeezing the ends together. Hose clamp pliers work best, but regular pliers will work also. If the radiator hose is stuck, grasp it near the end with a pair of adjustable pliers and twist it to break the seal, then pull it off. If the hose is old or if it has deteriorated, cut it off and install a new one. Remove the center support bolts and lift the center support from the engine compartment. Remove the left and right upper radiator support brackets. Tilt the radiator forward to make additional clearance for fan removal. Detach the wire harness from the fan shroud, remove the upper and lower fan shroud mounting bolts and then carefully lift the fan motor and shroud out of the engine compartment as a single assembly. Remove the fan mounting screws. To detach the fan blade from the motor, remove the nut or retaining clip from the motor shaft. Remove the fan blade from the motor. To detach the motor from the shroud, remove the retaining bolts. Remove the motor from the shroud. Installation is the reverse of removal. Make sure the rubber air shields around the shroud are still in place-without them, the cooling system may not work efficiently. Reconnect the battery and refill the cooling system. After you're done, the Powertrain Control Module (PCM) must relearn its idle and fuel trim strategy for optimum driveability and performance. Start the engine and allow it to reach normal operating temperature, then check for leaks and proper operation. Raise the vehicle and support it securely on jackstands. Drain the engine coolant. Remove the front bumper cover. Remove both airbag sensors. Disarm the airbag system before performing any work in the area of the cooling fans. Remove the brackets from the top of the radiator. Remove the nut and bolts from the hood latch, then set the latch aside with the cable attached. Detach the wiring harness clips from the radiator. Remove the bolt from the vertical center brace in front of the radiator. On four cylinder models, disconnect the wiring from the fan resistor, then disconnect the coolant recovery hose and push it to the side. Disconnect the wiring from the cooing fans. Remove the two cooling fan mounting bolts and carefully lift the fan assembly out of the engine compartment. Installation is the reverse of removal.

To remove the radiator fan and motor, follow these steps: 1. Disconnect the cable from the negative battery terminal. 2. Disconnect the fan motor electrical connector(s). 3. Raise the vehicle and secure it on jackstands. 4. Drain the cooling system, saving the coolant if it's relatively new and still in good condition. 5. Remove the hood latch and the upper radiator hose. 6. Loosen the hose clamp and remove the upper radiator hose. If the hose is stuck, use adjustable pliers to twist and break the seal before pulling it off. Consider installing a new hose if it's old or deteriorated. 7. Remove the center support bolts and lift the center support from the engine compartment. 8. Remove the left and right upper radiator support brackets to tilt the radiator forward for additional clearance. 9. Detach the wire harness from the fan shroud, and remove the upper and lower fan shroud mounting bolts. 10. Carefully lift the fan motor and shroud out of the engine compartment as a single assembly. 11. Remove the fan mounting screws. To detach the fan blade from the motor, remove the nut or retaining clip from the motor shaft. 12. Separate the fan blade from the motor and then detach the motor from the shroud by removing the retaining bolts. 13. Installation is the reverse of removal. Ensure that the rubber air shields around the shroud are in place for efficient cooling system operation.
