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 2016 INFINITI Q50, start with the simplest solutions before moving on to more complex diagnostics. Begin by checking the fuse associated with the radiator fan, as a blown fuse is a common and easily fixable issue that can halt fan operation. If the fuse is intact, proceed to inspect the relay, which controls the power supply to the fan; a malfunctioning relay may need replacement. Next, test the fan motor directly by applying power to it; if it fails to operate, this indicates that the motor itself may require replacement. Additionally, examine the temperature sensor, as a faulty sensor can prevent the fan from activating when necessary. Lastly, inspect the wiring for any signs of damage or loose connections, as these can disrupt the power flow to the fan. If these steps do not resolve the issue, it may be time to consult a mechanic or an authorized INFINITI service center for a professional diagnosis. By following this structured approach, you can efficiently identify and address the problem with your radiator fan.
When diagnosing why the radiator fan in a 2016 INFINITI Q50 has stopped working, it's essential to consider several common problems that could be at play. A faulty fan motor is often the primary culprit; if the motor fails, the fan will be unable to spin, leading to inadequate cooling of the radiator. Additionally, a blown fuse can interrupt the power supply to the fan, rendering it inoperative until the fuse is replaced. Another potential issue is a malfunctioning temperature sensor, which is responsible for signaling the fan to activate when the engine reaches a certain temperature. If this sensor is defective, it may fail to trigger the fan when necessary. Wiring issues, such as damaged or corroded connections, can also prevent the fan from receiving power, leading to operational failure. Lastly, a coolant leak can cause the engine to overheat, which may affect the fan's performance. By systematically checking these common problems, you can effectively troubleshoot and resolve the issue with your radiator fan.
Addressing a non-working radiator fan in your 2016 INFINITI Q50 is not just a matter of convenience; it is a critical safety concern that requires immediate attention. The radiator fan plays a vital role in regulating engine temperature by dissipating heat from the radiator. When this fan fails, the engine is at risk of overheating, which can lead to severe damage, including warped cylinder heads or a blown head gasket. Such issues not only compromise the vehicle's performance but can also leave you stranded, facing costly repairs and potential safety hazards on the road. Moreover, neglecting this problem can adversely affect other components of the cooling system, leading to a cascade of failures that could escalate repair costs significantly. Therefore, it is essential to diagnose and fix a non-working radiator fan promptly to maintain the integrity of your vehicle and ensure your safety while driving.
