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 a non-functioning radiator fan in your 2018 Volvo S60, begin with the simplest solutions before progressing to more intricate assessments. Start by checking 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, inspect the relay that controls the fan, as a faulty relay can also prevent the fan from activating. Next, test the radiator fan motor itself to ensure it is operational; if it fails to run, replacement may be necessary. Additionally, examine the wiring connected to the fan for any signs of damage or loose connections, as these can disrupt power supply. Utilizing a diagnostic tool to scan for error codes can provide further insights into any underlying issues within the fan system. Lastly, verify that coolant levels are sufficient, as low coolant can lead to overheating and affect fan functionality. By following this structured approach, you can efficiently identify and resolve the problem with your radiator fan.
When troubleshooting the radiator fan issue in a 2018 Volvo S60, it's essential to consider several common problems that could be at play. A faulty fan motor is often the primary culprit, as it directly affects the fan's ability to operate and cool the radiator. Additionally, a blown fuse can interrupt the electrical flow necessary for the fan to function, making it a quick check during your DIY diagnosis. The temperature sensor also plays a critical role; if it fails, it may not signal the fan to activate when the engine reaches a certain temperature, leading to overheating. Wiring issues can further complicate matters, as damaged or corroded connections can prevent power from reaching the fan. It's also wise to check the coolant level, as low coolant can trigger safety mechanisms that disable the fan to prevent engine damage. Lastly, relay problems can disrupt the fan's operation, so inspecting the relay for faults is a crucial step in your troubleshooting process. By systematically addressing these potential issues, you can effectively identify and resolve the reason your radiator fan is not working.
Addressing a non-working radiator fan in your 2018 Volvo S60 is critical to maintaining the health of your vehicle. The radiator fan plays a vital role in regulating engine temperature by dissipating heat from the radiator. When this fan fails, the risk of engine overheating significantly increases, which can lead to severe damage to engine components, including the possibility of the engine seizing. This not only results in costly repairs but could also necessitate a complete engine replacement. Furthermore, an overheating engine can leave you stranded on the road, requiring towing services and further inconveniencing your day. Additionally, neglecting this issue can adversely affect your vehicle's performance and fuel efficiency, leading to increased operational costs. Therefore, it is essential to promptly diagnose and repair a non-working radiator fan to avoid these serious consequences and ensure the longevity of your Volvo S60.
