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 2012 Volvo S60, start with the simplest checks before moving on to more complex diagnostics. Begin by ensuring that your coolant levels are adequate, as low coolant can prevent the fan from operating correctly. Next, test the radiator fan itself by connecting it to a 12v battery to see if it spins; this will confirm whether the fan is operational. If the fan does not turn on, inspect the fuses and relays associated with the engine fan and air conditioning system using a multimeter to ensure they are functioning properly. Additionally, check the fan module for any signs of malfunction, as it is a critical component that integrates with the fan. The temperature control sensor also plays a vital role in regulating fan operation, so ensure it is working correctly. Don’t forget to verify the high-speed fan setting and check the A/C clutch connection, as these can impact fan performance. Finally, using a scan tool can provide valuable insights by monitoring the Engine Coolant Temperature (ECT) and testing the fan's behavior when the A/C is activated. By following this structured approach, you can systematically identify the root cause of the radiator fan issue in your vehicle.
When diagnosing the radiator fan issues in a 2012 Volvo S60, it's essential to explore several common problems that could be causing the malfunction. A primary suspect is the thermostat, which can either fail to open or close properly, leading to erratic fan behavior. Inspecting the thermostat for any signs of wear or corrosion is a vital step in your troubleshooting process. Additionally, problems with the instrument cluster can mislead you into thinking the fan is at fault; if the vehicle runs smoothly but the fan isn't operating, checking the fuse for the instrument panel and utilizing a Volvo scanner to read fault codes from the IC module can help clarify the situation. Furthermore, the fan module itself is a key component that, if defective, may need replacement to restore the fan's functionality. By addressing these issues promptly, you can prevent potential engine overheating and maintain the overall health of your vehicle.
Repairing a non-functioning radiator fan in your 2012 Volvo S60 is not just a matter of convenience; it is a critical step in safeguarding your engine from overheating. When the radiator fan fails, it can lead to severe consequences, including engine damage and costly repairs. The radiator fan is essential for dissipating heat generated by the engine, and without it functioning properly, the engine temperature can rise to dangerous levels. This overheating can stress the entire cooling system, potentially resulting in coolant leaks and further complications. If you notice your engine temperature gauge rising or hear unusual noises from the fan area, it is imperative to act quickly. Delaying repairs can exacerbate the problem, leading to more extensive damage and increased repair costs. Therefore, addressing any signs of a malfunctioning radiator fan promptly is essential to maintain your vehicle's performance and longevity.
