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 2016 INFINITI QX60, it's crucial to follow a structured diagnostic approach that prioritizes simpler checks before moving on to more complex issues. Begin by examining the fuse linked to the radiator fan, as a blown fuse is a common culprit that can easily be replaced. If the fuse is in good condition, proceed to inspect the relay responsible for controlling the fan; a faulty relay can disrupt the power supply to the fan. Next, test the radiator fan motor itself to confirm its functionality, since a defective motor will need to be replaced. It's also important to check the wiring connected to the fan for any signs of damage or loose connections, as these can impede power delivery. Utilizing a diagnostic scanner can help identify any error codes related to the fan system, providing valuable insights into potential issues. Finally, ensure that the coolant temperature sensor is operating correctly, as a malfunctioning sensor can affect the fan's performance. By systematically addressing these areas, you can effectively diagnose and resolve the issue with the radiator fan, ensuring optimal vehicle performance.
When the radiator fan in a 2016 INFINITI QX60 ceases to function, it can lead to serious engine overheating issues, making it crucial to identify the underlying problems. One of the most common culprits is a faulty fan motor, which may fail to spin and adequately cool the engine. Additionally, a blown fuse in the fan circuit can interrupt the power supply, preventing the fan from operating. Another potential issue is a defective relay that controls the fan's operation; if this relay malfunctions, the fan may not activate when needed. Furthermore, a malfunctioning coolant temperature sensor can fail to signal the fan to turn on at the correct temperature, contributing to overheating. Lastly, wiring issues, such as damaged or corroded connections, can disrupt the electrical flow to the fan, causing it to stop working altogether. Addressing these problems promptly is essential to maintain the vehicle's performance and prevent costly repairs.
When faced with a non-functioning radiator fan in your 2016 INFINITI QX60, the urgency of repair cannot be overstated. The radiator fan is essential for regulating the engine's temperature, and without it, the risk of overheating increases significantly. Overheating can lead to severe engine damage, including blown head gaskets and warped cylinder heads, which can result in costly repairs. Additionally, driving with a malfunctioning fan places undue stress on the engine and other components of the cooling system, potentially exacerbating the problem over time. For DIY enthusiasts, it is crucial to diagnose and address this issue promptly to maintain your vehicle's performance and reliability. Taking immediate action not only safeguards your engine but also helps avoid the financial burden of extensive repairs down the line. Therefore, if you notice any signs of a failing radiator fan, prioritize its repair to ensure your INFINITI QX60 remains in optimal condition.
