The most common reasons a 2014 Buick Verano 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 2014 Buick Verano 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.

What steps should I take to diagnose the non-functioning radiator fan in my 2014 Buick Verano?

To effectively diagnose a non-functioning radiator fan in your 2014 Buick Verano, begin with a systematic approach that prioritizes simpler checks before moving on to more complex diagnostics. Start by inspecting the fuse associated with the radiator fan; a blown fuse is a common and easily fixable issue that can halt fan operation. If the fuse is intact, proceed to examine the relay, which is responsible for supplying power to the fan. A malfunctioning relay may require replacement. Next, test the fan motor directly by applying power to it; if it fails to operate, the motor itself may need to be replaced. Additionally, check the temperature sensor, as it is crucial for activating the fan when the engine reaches a certain temperature. Don’t overlook the wiring connected to the fan; damaged or loose connections can disrupt functionality. Finally, ensure that coolant levels are adequate, as low coolant can prevent the fan from operating correctly. By following this structured diagnostic approach, you can identify and resolve the issue with your radiator fan efficiently.

What are the common problems that could cause the radiator fan to stop working in a 2014 Buick Verano?

When diagnosing why the radiator fan in a 2014 Buick Verano has stopped working, it's essential to consider several common problems that could be at play. One of the primary culprits is a faulty fan motor, which may fail due to age or electrical malfunctions, preventing the fan from operating. Additionally, a blown fuse can interrupt the power supply to the fan, making it crucial to check the fuse box and replace any blown fuses. Another potential issue is a malfunctioning temperature sensor; if this sensor fails, it may not signal the fan to activate when the engine reaches a certain temperature, leading to overheating. Furthermore, a broken or slipping fan belt can hinder the fan's performance, so inspecting the belt for any signs of wear is advisable. Lastly, a coolant leak can trigger the fan to stop working as a protective measure against overheating, so ensuring the coolant system is intact and properly filled is vital. By systematically checking these components, DIYers can effectively troubleshoot and address the radiator fan issues in their Buick Verano.

How urgent is it to repair the non-functioning radiator fan in a 2014 Buick Verano to prevent engine overheating?

Repairing a non-functioning radiator fan in a 2014 Buick Verano is an urgent matter that should not be overlooked. The radiator fan is essential for regulating the engine's temperature by dissipating heat generated during operation. When this component fails, the engine is at risk of overheating, which can lead to severe damage, including blown head gaskets and damaged pistons. Additionally, overheating can compromise the integrity of engine oil and coolant, resulting in further complications and costly repairs. Ignoring the signs of a malfunctioning radiator fan not only increases the likelihood of engine failure but also poses safety risks while driving. Therefore, it is crucial to address any issues with the radiator fan immediately to ensure the engine operates within its optimal temperature range and to prevent extensive damage that could lead to significant repair costs down the line.
