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 diagnosing a non-working radiator fan in a 2015 INFINITI QX60, it's crucial to follow a structured diagnostic approach that prioritizes simpler checks before moving on to more complex issues. Begin by inspecting the fuse related to the radiator fan, as a blown fuse is a common culprit that can easily be replaced. If the fuse is functioning, the next logical step is to examine the relay that controls the fan; a faulty relay can disrupt the power supply to the fan. After confirming the relay's condition, test the radiator fan motor itself to ensure it operates correctly, as a malfunctioning motor will need to be replaced. Additionally, check the wiring connected to the fan for any signs of wear, damage, or loose connections, as these can impede electrical flow. To gain further insights, use a diagnostic scanner to check for any error codes that may indicate specific problems within the fan system. Finally, verify that the coolant temperature sensor is working properly, as a defective sensor can lead to fan operation issues. By systematically addressing these areas, you can effectively diagnose and resolve the problem with the radiator fan in your INFINITI QX60.
When dealing with a non-functioning radiator fan in a 2015 INFINITI QX60, it's crucial to understand the common problems that could be at play. One of the primary culprits is a faulty fan motor, which can fail to spin and lead to overheating. Additionally, a blown fuse in the fan circuit can interrupt the power supply, rendering the fan inoperative. Another potential issue is a defective temperature sensor that may not signal the fan to activate when necessary, resulting in inadequate cooling. It's also important to check the fan belt; if it's broken or slipping, it can hinder the fan's performance. Lastly, a coolant leak can cause the engine to overheat, which may prevent the radiator fan from functioning properly. Addressing these issues promptly is essential to avoid engine damage, and regular maintenance can help catch these problems early, ensuring your vehicle runs smoothly.
When it comes to the non-functioning radiator fan in a 2015 INFINITI QX60, the urgency of repair cannot be overstated. The radiator fan is essential for regulating the engine's temperature by ensuring that the radiator remains cool, especially during heavy driving or in hot weather. If the fan fails, the engine is at risk of overheating, which can lead to severe consequences such as warped cylinder heads or blown head gaskets. These issues not only compromise the engine's integrity but can also result in costly repairs that could have been avoided with timely intervention. Additionally, operating the vehicle under these conditions places undue stress on other components, potentially leading to a cascade of mechanical failures. Therefore, addressing the malfunctioning radiator fan should be a top priority for any owner of a 2015 INFINITI QX60 to safeguard against significant engine damage and ensure the vehicle's longevity and performance.
