Acura 19020-PH7-661 Cooling Fan (Denso)

To test the fan motor works, disconnect it from its electrical cable and power it directly from your car battery with short wires. If the fan still doesn't work, replace the motor. The bad part is either damaged fuses, the coolant temperature switch, the resistor, the relay, or the connectors between them. To see if the switch works, separate the plug and join its two terminals together. Turn the key on and leave the engine off for protection - the fan must turn on during this test. Double-check fuses, wiring, and connection points to see if anything is wrong. When there are no clear problems, take your car to a car service shop for further testing and repair. Unplug the battery with the negative terminal wire first. Pull on the parking brake then wedge something behind the back wheels to keep the car from moving during work. After lifting the front of your car, place it safely on jackstands before starting work. Remove the lower splash pan under the radiator. Push a small screwdriver behind a thin metal tab on the fan cable connecter, lift the tab with the screwdriver, then remove the cables. Remove the fan lower mounting bolts. Take off both fan upper brackets and condenser mounting hardware. Remove the upper radiator support bar. After lowering the radiator, move it just ahead and remove the engine fan from its place above. Before taking apart the fan from the motor, free it by removing either the shaft nut or screws. Screwing out the fan motor's mounting screws is needed to take out the bracket. Installation is the reverse of removal.
