Frequently Asked Questions (FAQs)

1. What relay controls the radiator fan?

The cooling fan relay is responsible for controlling the engine's cooling fans. It regulates when the fans turn on and off based on the temperature of the engine.

2. What are the symptoms of a bad cooling fan relay?

Some common symptoms of a bad cooling fan relay include the engine running hot or overheating, the cooling fans not working, the cooling fans continuously running, warning lights indicating a problem, poor air conditioning performance, and unusual noises. If you experience any of these issues, it may indicate a faulty cooling fan relay.

3. What happens when a radiator fan relay goes bad?

When a radiator fan relay goes bad, the cooling fans may not start. This can result in the radiator not being able to cool the engine properly, leading to overheating. The relay is responsible for supplying power to the fan, so if it fails, the fan won't work and the engine's temperature may rise.

4. What sensor triggers radiator fan?

In most modern cars, the cooling fan is triggered by the Engine Control Unit (ECU), which receives a signal from the coolant temperature sensor. If the coolant temperature sensor is not working properly, it may not send the signal to turn on the fan when necessary, potentially causing the engine to overheat.

5. What happens when a cooling fan resistor goes bad?

When a cooling fan resistor fails or has issues, it can result in power being cut off from the cooling fans. This can lead to overheating of the engine. If you notice any signs of overheating, it is important to address the issue promptly to avoid potential damage to the engine.
