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 2017 Nissan NV200, start with a systematic approach that prioritizes simpler checks before moving on to more complex diagnostics. Begin by inspecting the fuse associated with the radiator fan; a blown fuse is a common and easily fixable issue that can halt fan operation. If the fuse is intact, proceed to examine the relay, which is responsible for supplying power to the fan. A malfunctioning relay may need replacement to restore functionality. Next, test the fan motor directly by applying power to it; if it fails to operate, the motor itself may require replacement. Additionally, check the temperature sensor, as a faulty sensor may not signal the fan to activate when the engine reaches the necessary temperature. Lastly, inspect the wiring for any signs of damage or loose connections, as these can disrupt power flow to the fan. If these steps do not resolve the issue, consulting a professional mechanic is advisable for a thorough diagnosis and repair. By following this structured approach, you can efficiently identify and address the problem with your radiator fan.
When dealing with a non-functioning radiator fan in a 2017 Nissan NV200, it's essential to understand the various common problems that could be at play. A faulty fan motor is often the primary suspect, as it directly impacts the fan's ability to cool the radiator. Additionally, a blown fuse can interrupt the electrical supply, rendering the fan inoperative. It's also crucial to consider the temperature sensor; if it malfunctions, it may fail to signal the fan to activate, leading to overheating issues. Wiring problems, such as damaged or corroded connections, can further complicate matters by preventing power from reaching the fan. Low coolant levels can also hinder the fan's operation, as the system relies on adequate coolant to regulate engine temperature. Lastly, relay issues can obstruct the fan's functionality by failing to send the necessary signals for activation. By systematically checking these components, DIYers can effectively diagnose and resolve the radiator fan issue, ensuring optimal performance of their vehicle.
When it comes to the non-working radiator fan in a 2017 Nissan NV200, 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. If the fan fails, the engine is at a high risk of overheating, which can lead to severe damage 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, an overheating engine can adversely affect other critical components, including the water pump and thermostat, further escalating repair expenses. Ignoring the malfunctioning fan can also diminish engine performance and efficiency, as the engine struggles to maintain optimal operating conditions. Therefore, addressing the issue promptly is vital to safeguard the vehicle's health and prevent significant financial repercussions down the line.
