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.
To effectively diagnose the non-functioning radiator fan in your 2013 Hyundai Tucson, begin by inspecting the fan assembly and its components, including the fan clutch and coolant temperature sensor, as these are often the most straightforward issues to identify. Next, examine the electrical connections for any signs of looseness or corrosion, which can disrupt the fan's operation. Testing the fan relay is crucial, as a faulty relay can prevent the fan from receiving power. Ensure you check the wiring for proper voltage and continuity, as this will help pinpoint any electrical issues. If the fan remains unresponsive after these checks, evaluate the fuse, relay, fan motor, and thermostat for potential failures. By following this structured diagnostic approach, you can systematically identify and address the root cause of the radiator fan malfunction, ensuring your vehicle operates efficiently. If all else fails, seeking professional assistance may be necessary for a thorough diagnosis and repair.
When dealing with radiator fan failure in a 2013 Hyundai Tucson, it's essential to understand the common problems that can arise. One of the primary culprits is a blown fuse, which can interrupt the electrical current necessary for the fan's operation. Additionally, wiring issues, such as poor connections or damaged wires, can prevent the fan from receiving power. A faulty coolant temperature sensor may also be at fault, as it sends signals to the engine control unit (ECU) to activate the fan; if this sensor malfunctions, the fan may not turn on when needed. Another potential issue is a defective cooling fan relay, which acts as a switch to energize the fan circuit. Lastly, a bad wiring harness can lead to persistent fan failures, as simply replacing a blown fuse without addressing the underlying wiring problems may result in recurring issues. By understanding these common failure modes, DIYers can effectively diagnose and troubleshoot radiator fan problems in their Hyundai Tucson, ensuring optimal performance of the vehicle's cooling system.
Fixing the radiator fan in a 2013 Hyundai Tucson is not just a matter of convenience; it is an urgent necessity to maintain the vehicle's safety and performance. A malfunctioning radiator fan can lead to severe engine overheating, which poses a significant risk of extensive damage and costly repairs. When the fan fails to activate, the engine may overheat, leading to potential engine failure and damage to other critical components. This situation can escalate quickly, resulting in a breakdown that could leave you stranded or, worse, cause a dangerous situation on the road. Therefore, if you notice any signs of a faulty radiator fan, such as unusual noises or the engine temperature gauge rising, it is crucial to address the issue immediately. Prompt action not only protects your vehicle from further damage but also ensures your safety while driving.
