The most common reasons a Chevrolet Equinox radiator fan isn't working are the fan assembly, the fan clutch, or the coolant temperature sensor.
  • Fan Motor or Clutch: A faulty fan motor or a malfunctioning fan clutch can result in inadequate cooling, causing the engine to overheat.
  • Fan Relay or Fuse: A faulty fan relay or blown fuse can prevent the cooling fan from operating, leading to engine overheating.
  • Temp Sensor or Fan Control Module: A faulty temperature sensor or fan control module can result in incorrect readings, causing the engine to overheat or the cooling fan to operate improperly.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a Chevrolet Equinox radiator fan isn't working?

Common Repairs

The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.

Over time serpentine belts stretch, crack, and the ribs that ride on the accessory pulleys being to wear smooth. A squealing noise that increases with engine speed or as engine driven accessories are turned on may be noted. The noise is caused by the belt slipping on the pulleys, insufficiently driving them. Ineffective air conditioning, a battery warning light, or intermittent power steering assist can result from this.

The bad thermostat can cause two different sets of problems, depending on whether it's stuck open or stuck closed.

A thermostat that is stuck open can cause the engine to run colder than normal and turn on the check engine light. It may also cause poor fuel mileage and the heater to blow cool air.

A thermostat that is stuck closed will cause the vehicle to overheat. If a new thermostat doesn't resolve engine temperature problems, the cooling system needs to be checked for other issues.

When the engine coolant temperature sensor fails, it will send inaccurate information to the vehicle’s computer, causing the computer to react to false operating conditions. This will cause the engine to consume more fuel than normal, depleting fuel mileage, and causing black, sooty smoke from the engine under moderate to heavy acceleration. The check engine light will illuminate, and on-board diagnostic trouble codes may be stored for exhaust and emission system failure, fuel delivery system failure, and engine cooling system failure. Overheating may also occur, as the coolant sensor may be leaking fluid out of the engine, creating a an air pocket in the system.

When the radiator fans stop functioning properly, the engine temperature will rise. The spike in temperature will be highest when the vehicle is idling at a stop, but should subside once the vehicle begins moving again.

Additionally, the air conditioner typically won't blow as cold. This is because the air from the radiator fans also blows across the air conditioning condenser, so when the fans fail, both systems suffer.

You'll also usually see the check engine light and notice a drop in fuel economy. It's possible the fan will start making noise if it's failing, as well.

Troubleshooting Radiator Fan Issues in a Chevrolet Equinox

When troubleshooting radiator fan issues in your Chevrolet Equinox, it's essential to adopt a systematic diagnostic approach. Start by checking the fuse associated with the radiator fan, as a blown fuse is a common and easily fixable problem. Next, inspect the coolant level; low coolant can disrupt the engine temperature sensor's function, leading to fan malfunctions. If these initial checks do not resolve the issue, examine the fan clutch for wear, as a faulty clutch can prevent the fan from operating correctly. Additionally, consider the electronic components involved, such as the Engine Control Module (ECM), fan relay, and temperature sensors, as faults in these areas can cause the fan to run continuously or not at all. Utilizing a scan tool to access the cooling system module can provide valuable insights into any ECM-related issues. If you find yourself unable to pinpoint the problem after these steps, seeking professional assistance from a service center specializing in Chevrolet vehicles may be the best course of action. By following this structured approach, you can effectively diagnose and address radiator fan problems in your Equinox, ensuring optimal vehicle performance.

What Are the Common Causes of a Non-Working Radiator Fan in a Chevrolet Equinox?

When dealing with a non-working radiator fan in a Chevrolet Equinox, it's essential to understand the common problems that could be at play. One of the first things to check is the fuse associated with the radiator fan; a blown fuse is a frequent culprit that can easily be replaced. Next, consider the relay, as a faulty relay can disrupt the power supply to the fan, preventing it from operating. Inspecting the wiring for any breaks or damage is also crucial, as a broken wire can interrupt the electrical flow necessary for the fan to function. Additionally, the coolant temperature sensor plays a vital role in regulating the fan's operation; if this sensor is malfunctioning, it may not signal the fan to turn on when needed. Lastly, be aware of other potential issues such as low coolant levels, short circuits, or even a damaged fan motor itself. By systematically addressing these common causes, you can effectively diagnose and resolve the issue with your radiator fan, ensuring your Chevrolet Equinox runs smoothly.

Why is the Radiator Fan Not Working in a Chevrolet Equinox?

When the radiator fan in your Chevrolet Equinox is not functioning, it is crucial to address the problem promptly to avoid severe consequences. A malfunctioning fan can lead to overheating, which may cause significant engine damage and costly repairs. Common culprits include a faulty fan assembly, a defective fan clutch, or issues with the coolant temperature sensor. Additionally, electrical problems such as a blown fuse, a bad relay, or damaged wiring can prevent the fan from operating correctly. If you notice that the cooling fan continues to run after the engine is off, it may indicate issues with the ECU, coolant levels, or temperature sensors that require immediate attention. By diagnosing and resolving these issues quickly, you can ensure the longevity of your vehicle and maintain its performance, making it essential for any DIY enthusiast to take these symptoms seriously.
