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-functioning radiator fan in your 2016 INFINITI Q70L, it's crucial to follow a methodical diagnostic approach that prioritizes simpler fixes before delving into more complex issues. Begin by checking the fuse related to the radiator fan, as a blown fuse is a common culprit that can easily be replaced. If the fuse is intact, inspect the relay that controls the fan; a malfunctioning relay can prevent the fan from operating. Should these components be in good condition, the next step is to test the radiator fan motor itself, as a defective motor will need to be replaced. Additionally, examine the wiring for any signs of damage or loose connections, which can disrupt the fan's functionality. It's also important to ensure that coolant levels are sufficient, as low coolant can lead to overheating and impact fan performance. Finally, utilizing a diagnostic scanner to check for any error codes can help identify specific issues within the system. If these steps do not yield results, seeking assistance from a mechanic or dealership is recommended for a thorough diagnosis and repair. By adhering to this structured approach, you can effectively troubleshoot and resolve the issue with your radiator fan.
When diagnosing why the radiator fan in a 2016 INFINITI Q70L has stopped working, it's essential to consider several common issues 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, resulting in inadequate cooling for the radiator. Additionally, a blown fuse can disrupt the electrical flow to the fan, necessitating a simple fuse replacement to restore functionality. Another potential issue is a malfunctioning temperature sensor, which may fail to signal the fan to activate when the engine reaches high temperatures. Wiring problems, such as damaged or corroded connections, can also prevent the fan from receiving power, leading to operational failure. Furthermore, a coolant leak can cause the engine to overheat, which may hinder the fan's ability to cool effectively. Lastly, a failed fan relay can stop the power supply to the fan altogether. By systematically checking these components, DIYers can effectively troubleshoot and resolve the radiator fan issue in their vehicle.
When it comes to the radiator fan in your 2016 INFINITI Q70L, urgency is key. A non-functioning radiator fan can lead to severe overheating, which poses a significant risk to your engine's health. Without the fan's cooling action, the engine temperature can rise dangerously high, resulting in warped cylinder heads or blown head gaskets, both of which can lead to costly repairs or even complete engine failure. Additionally, driving under these conditions places undue stress on the entire cooling system, potentially exacerbating existing issues and leading to further damage. Therefore, if you notice that your radiator fan is not operating, it is crucial to address the problem immediately. Prioritizing this repair not only safeguards your engine's performance but also helps you avoid more extensive and expensive repairs down the line. Taking swift action ensures that your vehicle remains reliable and safe on the road.
