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. Finally fixed the problem with nissan 350z overheating , and cooling fans dying often , the problem was in the bad fuse box relay contacts!!!.
Engine Overheating Testing Cooling Fans Relays Ipdm Fuse Box Conection Testing low and high speed cooling fan relays. subscribe: carsntoys tools and supplies: amazon shop carsntoys mult. 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. 4. using a mirror to observe the fan. if the fan is not easily visible, use a hand mirror to observe it while the engine runs. position the mirror in a way that lets you see the fan without putting your hands near moving parts. this technique helps in checking if the fan is spinning without direct visual access. 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.

The cooling fan kicks in and sends air flows to the engine. the air flows will continue until the sensor or ecm informs the relay that the temperature is normal again. then, the relay returns another electric charge to the radiator to switch off the cooling fan. with this, the relay is an intermediary between the sensor ecm and the radiator fan. Step 2: remove the fuse relay box cover. remove the cover from the top of the underhood fuse relay box. this will be accomplished by removing or releasing any combination of retaining clips or fasteners. step 3: identify the cooling fan relay. we must now identify which relay is the cooling fan relay. most manufacturers will print a diagram on.
