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.
To diagnose the non-functioning radiator fan in your 1996 Hyundai Sonata, start with the most straightforward checks to avoid unnecessary complications. Begin by verifying the coolant level, as low coolant can hinder the fan's operation. If the coolant is adequate, proceed to inspect the fuse associated with the radiator fan; a blown fuse is a common and easily fixable issue. Next, test the fan assembly itself to confirm it is operational. If the assembly is intact, check the coolant temperature sensor, as a faulty sensor can disrupt the fan's functionality. Additionally, examine the wiring connected to the fan for any signs of damage or loose connections, as these can prevent proper operation. Finally, test the radiator fan motor to ensure it is functioning correctly. By following this diagnostic approach, you can systematically identify the cause of the radiator fan issue and take the necessary steps to resolve it, ensuring your Hyundai Sonata runs smoothly.
When diagnosing why the radiator fan is not working in a 1996 Hyundai Sonata, it's essential to consider several common issues that could be at play. A blown fuse is often the first culprit to check, as it can easily disrupt the electrical flow to the fan. If the fuse appears damaged, replacing it may restore functionality. Another potential issue is a faulty relay, which controls the power to the fan; testing and replacing the relay can resolve this problem. Additionally, inspect the wiring for any breaks or damage, as a broken wire can prevent the fan from operating. The coolant temperature sensor is also critical; if it malfunctions, it may not signal the fan to turn on when needed, necessitating a replacement. Furthermore, ensure that the coolant level is adequate, as low coolant can affect the fan's performance. Lastly, examine the fan itself for any physical damage, as a damaged fan will require replacement to restore proper operation. By systematically checking these components, DIYers can effectively troubleshoot and resolve radiator fan issues in their Sonata.
Fixing the radiator fan in your 1996 Hyundai Sonata is an urgent matter that should not be overlooked. The radiator fan is essential for maintaining optimal engine temperature by dissipating heat from the radiator. If the fan fails to operate, the engine can quickly overheat, leading to severe mechanical failures that could result in costly repairs. Symptoms such as smoke from under the hood or a temperature gauge that spikes should serve as immediate red flags. Ignoring these signs can escalate the situation, potentially causing catastrophic damage like a blown head gasket. Moreover, the risk of overheating is particularly pronounced in stop-and-go traffic or during low-speed driving, where the fan's role becomes even more critical. Therefore, addressing any issues with the radiator fan promptly is vital to ensure the longevity and reliability of your vehicle, making it imperative to seek professional help if you encounter any problems.
