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.
To effectively diagnose the non-functioning radiator fan in your 2012 Hyundai Tucson, start with a systematic approach that prioritizes simpler checks before delving into more complex diagnostics. Begin by inspecting the fuse associated with the radiator fan; a blown fuse is a straightforward fix that can often resolve the issue. Next, examine the relay, as it plays a critical role in powering the fan. If the relay is faulty, it can lead to overheating, so ensure it is functioning properly. After confirming these components, test the fan motor itself. You can do this by disconnecting the engine coolant temperature sensor, which may trigger the fan to activate. If the fan does not turn on, check for power and ground connections to the motor. Additionally, inspect other related components such as the fan control module, wiring harness, and coolant temperature sensor, as any malfunction in these parts can prevent the fan from operating. By following this diagnostic approach, you can efficiently identify and resolve the issue with your radiator fan, ensuring your vehicle remains in optimal working condition.
When diagnosing why the radiator fan in a 2012 Hyundai Tucson is not functioning, it's essential to consider several common problems that could be at play. One of the first things to check is the fuse associated with the radiator fan circuit, as a blown fuse can easily prevent the fan from operating. Additionally, the relay, which controls the electrical flow to the fan, may be faulty, or there could be broken wiring that disrupts the connection. Another critical component to inspect is the coolant temperature sensor; if it is malfunctioning, it may not signal the fan to activate when needed. Furthermore, ensure that the coolant level is adequate, as low coolant can lead to overheating and may affect fan operation. Lastly, examine the fan assembly itself for any signs of damage or wear. Addressing these issues promptly is vital, as neglecting a non-working radiator fan can lead to severe engine overheating and potential damage, especially in high-temperature conditions. By systematically checking these components, DIYers can effectively troubleshoot and resolve the radiator fan issue in their Tucson.

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.
