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.
When troubleshooting radiator fan issues in your Hyundai Entourage, it's essential to adopt a systematic diagnostic approach. Start by checking the simplest components, such as the fuse, which can often be the culprit if the fan isn't functioning. If the fuse is blown, replace it with one of the same size and type, but be cautious; if it blows again, this indicates a deeper electrical issue that may require further investigation. Next, inspect the fan assembly for any visible damage or obstructions that could hinder its operation. Cleaning any debris from the fan blades can sometimes resolve the issue. If the fan still fails to operate, consider testing the fan motor directly by wiring it to the battery to determine if it is functional. Should the fan motor work but the fan still does not engage, the problem may lie with the coolant temperature sensor or the fan control module, which may need replacement. By following this methodical approach, you can effectively diagnose and address radiator fan issues, ensuring your vehicle runs smoothly and efficiently.
When troubleshooting a non-functioning radiator fan in a Hyundai Entourage, it's crucial to systematically examine several key components that could be causing the problem. Start with the fan assembly itself, as physical damage or electrical issues within the assembly can prevent it from operating. Next, inspect the fan clutch, which is responsible for engaging the fan when needed; a malfunction here can lead to inadequate cooling. The coolant temperature sensor is another vital part to check, as it signals the fan to activate based on engine temperature. Additionally, the cooling fan relay, located in the engine compartment fuse box, should be tested, as a failure in this relay can disrupt the fan's operation. Don't overlook the cooling fan module connection, as loose or corroded connections can also lead to fan failure. Lastly, if you suspect the radiator fan relay is faulty, perform a simple test by jumping the relay pins to see if the fan activates. Addressing these components promptly is essential to prevent overheating and ensure your Hyundai Entourage runs smoothly. Regular maintenance and timely repairs will help keep your vehicle in optimal condition.
When the radiator fan in your Hyundai Entourage fails to operate, it is crucial to address the issue promptly to avoid serious consequences. A malfunctioning radiator fan can lead to overheating, which poses a significant risk to your engine's integrity and overall vehicle performance. Common culprits behind this problem include a faulty fan motor, a blown fuse, or a defective coolant temperature sensor, all of which can prevent the fan from activating when needed. Ignoring these symptoms can result in severe engine damage, especially in hot weather conditions where the cooling system is under increased stress. Therefore, if you notice that your radiator fan is not working, it is essential to diagnose the issue immediately. This proactive approach not only safeguards your vehicle's health but also ensures your safety on the road, as driving with an ineffective cooling system can lead to catastrophic failures.
