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 XC60, start by verifying the fan's operation. Begin by allowing the engine to reach its normal operating temperature and observe whether the fan activates. If it does not, inspect the fan blade and clutch for any visible damage, as a broken blade or malfunctioning clutch can prevent proper function. Next, check the fuses related to the engine fan and air conditioning system, as blown fuses can disrupt power to the fan. If these components appear intact, utilize an OBD-II scanner to read and clear any fault codes specific to your Volvo model, which can provide insights into underlying issues. Additionally, examine the temperature sensor and its connections, as a faulty sensor may misreport engine temperature, leading to fan inactivation. If these steps do not resolve the issue, consider consulting a professional mechanic or a Volvo specialist for a more thorough diagnosis. By following this structured approach, you can systematically identify and address the problem with your radiator fan.
When troubleshooting a non-functioning radiator fan in a 2012 Volvo XC60, it's essential to consider several common problems that could be at play. One of the first things to check is the fuse, as a blown fuse is a frequent culprit that can easily be replaced. If the fuse is intact, the next step is to inspect the fan motor itself; a faulty motor may require replacement to restore functionality. Additionally, the temperature sensor plays a critical role in signaling the fan to operate, so a defective sensor could prevent the fan from turning on when needed. Lastly, examine the fan relay, as a broken relay can disrupt the electrical signal necessary for the fan to function. By systematically checking these components, DIYers can effectively diagnose and address the issue, ensuring the radiator fan operates correctly to prevent engine overheating.
When it comes to maintaining your 2012 Volvo XC60, addressing a non-functioning radiator fan should be a top priority. The radiator fan plays a critical role in regulating engine temperature; without it, your engine is at a high risk of overheating. This overheating can lead to severe engine damage, which not only compromises vehicle performance but can also result in expensive repairs that could have been avoided. If you notice signs of overheating, such as the temperature gauge rising or steam coming from under the hood, it’s essential to act quickly. Ignoring these symptoms can exacerbate the problem, potentially straining the cooling system and leading to coolant leaks. By promptly repairing the radiator fan, you not only safeguard your engine's health but also enhance the overall efficiency of your vehicle, preventing future complications and ensuring a smoother driving experience. Therefore, if you find yourself facing this issue, don’t delay; addressing it now can save you time, money, and stress down the road.
