Why is the radiator fan not working on my Acura RDX?

Possible Reasons for Radiator Fan Not Working on Acura RDX
There can be several reasons why the radiator fan is not working on your Acura RDX. Here are some possible causes to consider:
1. Fan Assembly: The radiator fan assembly may be faulty and needs to be replaced.
2. Fan Clutch: The fan clutch, which helps regulate the speed of the radiator fan, may be worn out and not functioning properly.
3. Coolant Temperature Sensor: The coolant temperature sensor, which detects the engine temperature and signals the fan to turn on, may be faulty.
4. Fuse: Check the fuse for the radiator fan. If the fuse is blown, it can prevent the fan from working.
5. Wiring Issues: There may be wiring problems, such as loose connections or damaged wires, that are preventing the fan from receiving power.
6. Relay Switch: The relay switch that controls the radiator fan may be malfunctioning.
7. Other Factors: Other factors, such as a malfunctioning engine motor fan, faulty 02 sensors, or a breached radiator, could also contribute to the radiator fan not working.
It is recommended to start with the easier fixes, such as checking the coolant level and the fuse, before moving on to more complex troubleshooting steps. If you are unsure about diagnosing or fixing the issue yourself, it may be best to consult a professional mechanic for further assistance.

Can I drive car if radiator fan is not working?

Can I Drive My Car If The Fan Is Not Working? Yes, your car can still run without a radiator fan, but you never should. Your vehicle’s cooling system is crucial to the engine’s performance and lifespan. Every time your engine overheats, you’re causing tremendous damage to the precious engine.

Why is my radiator fan not engaging?

It could be a problem with the fan motor, temperature sensor, fan control relay, or wiring. The Check Engine Light might come on. With modern cars, a DTC will be triggered that illuminates the light on the dash when it exceeds normal operating temperatures. It might be accompanied by a message on the cluster too.

How do I know if my radiator fan fuse is blown?

You might see a temperature light pop up on your dashboard. In this case stop driving immediately. And turn off your car. The fifth symptom is a blown cooling fan fuse.

Is the radiator fan always supposed to be running?

In normal operation, no, the radiator fan doesn’t run all the time. The fan is hooked to a sensor that measures the coolant temperature in the radiator, and when the temperature gets a little on the high side, the sensor will (basically) send a signal that turns the fan on.

How much does it cost to repair a radiator fan?

The radiator fan replacement cost ranges from $400 to $1,000. The fan assembly costs between $100 to $600, and labor charges may be $115 to $375. The type and model of the car, whether you replace it by yourself or hire a technician, and where you buy the kit will determine the actual cost.

Can a bad thermostat cause fan not to come on?

An unlikely, but possible, cause is a bad thermostat. Try turning the Fan switch to the “On” position to see if the blower comes on. Watch the video. If the blower operates in the “On” position and does not operate when the air conditioner is running, you may have a bad thermostat.

When should radiator fan turn on?

between 200 and 230 degrees Fahrenheit
In most vehicles, the radiator fan is programmed to turn on when the engine coolant reaches a temperature between 200 and 230 degrees Fahrenheit (93 to 110 degrees Celsius). However, some vehicles may have different temperature thresholds for the radiator fan to activate.

What activates the radiator fan?

The engine temperature should trigger the fan to turn on. It will also turn the fan off once the engine has cooled to under 200 degrees. You may have heard of a part called the radiator fan switch or temperature fan switch. This is linked to a thermostat and works much like your home’s HVAC system.

What sensor turns on the radiator fan?

Yes, the coolant temperature sensor is an important component in controlling the radiator fan in many modern vehicles. The coolant temperature sensor monitors the temperature of the engine coolant and sends this information to the engine control module (ECM), which uses it to determine when to turn on the radiator fan.

What would cause a radiator fan to stop working?

The most common reasons for a radiator fan not working can be a blown-out fuse, a bad relay, or a broken wire. The faulty coolant temp sensor might also be a reason behind it.
