Overheating Help Testing Cooling Fans Relays Connections Youtube If your vehicle is overheating due to a non working cooling fan motor, this video will show the steps involved in diagnosing the problem. cooling fan motor t. Key points. recognize symptoms: engine overheating, poor a c, continuous fan operation, battery drain, risk of a c compressor damage. inspect for damage: check for corrosion, burnt marks, loose pins, cracked sockets in the relay. test functionality: use a multimeter, check for continuity resistance, listen for a click, inspect physically.
Overheating Help Testing Radiator Cooling Fan Youtube Remove the relay from the relay box and test it with a multimeter. set the multimeter to continuity mode and check the relay’s terminals. if there is no continuity, the relay is faulty and needs to be replaced. always disconnect the battery before removing the relay to avoid any accidental short circuits. For electric fans, testing the electrical connections, relays, and fuses can help identify the problem. fixing a cooling fan may involve replacing damaged components, repairing electrical connections, or installing a new fan assembly. ensuring that the cooling fan operates correctly is essential to prevent engine overheating and maintain. 1. verify the fan itself is good or bad. disconnect the wiring to the fan. connect the fan itself directly to the car battery. if the fan runs directly off the battery (for at least several minutes) with no problem then the electrical fan relay is worth checking by replacement. 2. Problems in the cooling fan relay circuit. the typical electric cooling fan circuit includes, a temperature sensor, a relay, a control module and the fan motor. the relay is the component that fails most often. so, be sure to test the relay, as well as its power supply and ground connections. a good relay coil will typically read 40 to 80 ohms.

If your vehicle is overheating due to a non working cooling fan motor, this video will show the steps involved in diagnosing the problem. cooling fan motor testing (low and high speeds), relays, harness connectors it's all here. generally, the low speed fan kicks on when the a c is turned on or when the coolant temperature hits around 200 degrees f. high speed kicks on around 220f. subscribe. Test the fan motor. connect the motor directly to 12 volt power with jumper wires to see if the fan spins properly. if it doesn’t, the motor is likely burnt out. check the coolant temperature sensor. a signal from the coolant temperature sensor is what triggers the ecu to turn on the radiator fan, and if it’s faulty, it can prevent the fan.
