radiator fan not working symptoms

If you notice that the radiator circuit fuse is blown it is a symptom of the radiator fan not working properly. You can also measure the relay coils resistance.

When To Replace A Radiator Cooling Fan Signs Symptoms

Ensure that the wires are firmly attached and are not damaged.

. Generally located by the thermostat housing this should be the first thing to check and replace since it is easy and inexpensive. All is quiet when the radiator fan is working you can hear a whir. Up to 8 cash back 1.

The sound is very noticeable and you should be able to hear it. Rising temperature in the gauge. Some cars have a temperature warning light.

If there is no whirring sound the radiator fan may have failed and must be taken to the mechanic as soon as possible. A blown circuit fuse a defective relay and engine overheating can all be caused by a bad radiator cooling fan. If the cooling fan doesnt engage there may be something wrong with the cooling fan relay.

The circuit fuse is designed to blow when there is a surge or fluctuation of power to keep the system safe. When you cannot hear any whirring noise when the car is on it may be because the fan is not working. Broken Wiring or Bad connection If the fan is not working even Exeed Radiator cooling fan the car is overheating there might be a wiring issue or a bad connection.
