The most common reasons a 2017 Hyundai Accent 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 2017 Hyundai Accent radiator fan isn't working?

Common Repairs

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 2017 Hyundai Accent?

To effectively diagnose a non-functioning radiator fan in your 2017 Hyundai Accent, begin with a systematic approach that prioritizes simpler checks before delving into 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 controls the power supply to the fan. A malfunctioning relay may require replacement to restore functionality. Next, test the fan motor directly by applying power to it; if the motor fails to operate, it likely needs replacement. Additionally, assess the temperature sensor, as a faulty sensor may not signal the fan to activate when the engine reaches the necessary temperature. Don’t overlook the wiring; inspect for any damage or loose connections that could disrupt power flow to the fan. If these steps do not resolve the issue, consulting a professional mechanic is advisable for a comprehensive diagnosis. By following this structured approach, you can efficiently identify and address the problem with your radiator fan.

What are the common problems that could cause the radiator fan to stop working in a 2017 Hyundai Accent?

When troubleshooting a non-functioning radiator fan in a 2017 Hyundai Accent, it's essential to consider several common issues that could be at play. A faulty fan motor is often the primary culprit, as it can fail to spin, leading to engine overheating. Additionally, a blown fuse in the fan circuit can interrupt the power supply, rendering the fan inoperative. Another critical component to check is the temperature sensor; if it malfunctions, it may not signal the fan to activate when the engine reaches high temperatures. Furthermore, inspect the fan belt for any signs of damage or slippage, as a broken belt can hinder the fan's performance. Lastly, be aware of any coolant leaks, as insufficient coolant can prevent the fan from functioning correctly, exacerbating overheating issues. By systematically examining these areas, DIYers can effectively diagnose and resolve radiator fan problems, ensuring their vehicle remains in optimal working condition.

How urgent is it to repair the non-functioning radiator fan in a 2017 Hyundai Accent to prevent engine overheating?

Repairing the non-functioning radiator fan in your 2017 Hyundai Accent 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 risk of engine overheating significantly increases, which can lead to severe consequences such as warped cylinder heads or blown head gaskets. These issues not only compromise the engine's integrity but can also result in costly repairs and extended periods of vehicle inoperability. Moreover, ignoring the malfunctioning fan can exacerbate the situation, leading to more extensive damage that could ultimately require a complete engine replacement. Therefore, addressing the radiator fan issue promptly is crucial for maintaining your vehicle's performance and avoiding the financial burden of extensive repairs. Prioritizing this repair will ensure the longevity of your engine and provide peace of mind while driving.
