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.
To effectively diagnose the non-functioning radiator fan in your 2009 Nissan Cube, begin with a systematic approach that prioritizes simpler checks before moving on to more complex diagnostics. Start 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 controls the power supply to the fan. A malfunctioning relay may require replacement to restore functionality. Next, test the fan motor directly by applying power to it; if it fails to operate, the motor itself may need replacement. Additionally, check the temperature sensor, as it plays a crucial role in signaling the fan to activate when the engine reaches a certain temperature. Lastly, inspect the wiring for any signs of damage or loose connections that could disrupt the fan's operation. If these steps do not resolve the issue, consulting a professional mechanic is advisable for further diagnosis and repair. 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 2009 Nissan Cube has stopped working, it's crucial to consider several common problems that could be at play. A faulty fan motor is often the primary suspect, as it can fail to spin, leading to overheating. Additionally, a blown fuse in the fan circuit can interrupt the power supply, rendering the fan inoperative. Another potential issue is a broken fan belt, which, if damaged, can prevent the fan from functioning effectively, compromising the cooling system. Furthermore, a malfunctioning temperature sensor may fail to signal the fan to activate when necessary, resulting in overheating. Lastly, a coolant leak can exacerbate the situation by causing the engine to overheat, which may affect the fan's operation. Addressing these issues promptly is essential to maintain optimal engine performance and prevent further damage, making regular maintenance and inspections vital for any DIY enthusiast.
Repairing a non-working radiator fan in a 2009 Nissan Cube is an urgent matter that should not be overlooked. The radiator fan is essential for regulating the engine's temperature by ensuring that the radiator remains cool, and when it fails, the risk of engine overheating significantly increases. Overheating can lead to severe damage, including warped cylinder heads and blown head gaskets, which can escalate repair costs dramatically. Additionally, an overheating engine can compromise the vehicle's overall performance and fuel efficiency, potentially leaving you stranded on the road. Therefore, addressing the issue promptly is crucial not only for the longevity of your vehicle but also for your safety and peace of mind. Taking immediate action to repair the radiator fan can prevent costly repairs and ensure that your Nissan Cube operates smoothly and efficiently.
