The most common reasons a 2017 Hyundai Veloster 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 Veloster 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 2017 Hyundai Veloster?

To effectively diagnose the non-functioning radiator fan in your 2017 Hyundai Veloster, 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 is crucial for powering the fan. A malfunctioning relay may need replacement to restore functionality. Next, test the fan motor itself to ensure it is receiving power and operating correctly; a failed motor will require replacement. Additionally, check the temperature sensor, as a faulty sensor can prevent the fan from activating when necessary. Don’t overlook the wiring connected to the fan; damaged or loose connections can disrupt power supply. Finally, verify that coolant levels are adequate, as low coolant can lead to overheating and affect fan performance. By following this diagnostic approach, you can efficiently identify and address the underlying issue with your radiator fan.

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

When diagnosing why the radiator fan in a 2017 Hyundai Veloster has stopped working, it's essential to consider several common problems that could be at play. A faulty fan motor is often the primary culprit; if the motor fails, the fan will not spin, leading to inadequate cooling of the radiator. Additionally, a blown fuse can interrupt the power supply to the fan, necessitating a simple fuse replacement to restore functionality. Another potential issue is a malfunctioning temperature sensor, which may fail to signal the fan to activate when the engine reaches high temperatures, resulting in overheating. Wiring problems, such as loose connections or frayed wires, can also disrupt the electrical flow to the fan, causing it to stop working. Lastly, low coolant levels can impact the fan's operation, as the fan relies on the coolant to help regulate engine temperature. By systematically checking these areas, you can effectively troubleshoot and resolve the issue with the radiator fan in your Veloster.

How urgent is it to address the non-functioning radiator fan in a 2017 Hyundai Veloster?

Addressing a non-functioning radiator fan in a 2017 Hyundai Veloster is of utmost urgency due to the vital role this component plays in maintaining engine temperature. The radiator fan is responsible for drawing air through the radiator to dissipate heat generated by the engine. When this fan fails, the engine is at risk of overheating, which can lead to catastrophic damage such as warped cylinder heads or complete engine failure. The potential for such severe consequences makes it essential to act quickly; ignoring the issue not only jeopardizes the engine's integrity but can also result in expensive repairs or even a full engine replacement. Therefore, if you notice any signs of a malfunctioning radiator fan, it is crucial to diagnose and resolve the problem immediately to safeguard your vehicle's performance and longevity.
