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 troubleshooting radiator fan issues in your INFINITI FX37, begin by assessing the most accessible components to identify the root cause of the problem. Start with a visual inspection of the fan assembly and wiring for any obvious signs of damage or disconnection. Next, check the coolant temperature sensor, as it plays a crucial role in signaling the fan to activate. If the fan is not running, it’s essential to verify the electrical connections, including fuses and relays, to rule out any electrical faults. If these initial checks do not resolve the issue, consider inspecting the thermostat, as a malfunctioning thermostat can also lead to overheating. Additionally, ensure that there is adequate airflow around the radiator; obstructions can hinder the fan's performance. If you have recently installed aftermarket parts, evaluate their quality and compatibility, as they may contribute to the problem. By following this structured diagnostic approach, you can effectively pinpoint and address radiator fan issues, ensuring your vehicle remains in optimal working condition.
When troubleshooting a non-working radiator fan in an INFINITI FX37, it's essential to identify the common problems that may be at play. A faulty fan assembly is often a primary suspect, as it can prevent the fan from functioning properly. Additionally, issues with the fan clutch can impede performance, leading to insufficient cooling. The coolant temperature sensor is another critical component; if it malfunctions, it may fail to signal the fan to activate when needed. Electrical system problems, such as faulty relays or blown fuses, can disrupt the power supply to the fan, causing it to stop working. If the radiator fan motor itself is defective, it will not operate, necessitating a replacement. Wiring issues, including frayed or damaged wires, can complicate the situation further. Broader cooling system problems, like a malfunctioning thermostat or low coolant levels, can also affect the fan's functionality. In some instances, only one fan may be operational, which can be inadequate during high-temperature conditions. Lastly, a worn fan bearing can lead to excessive current draw, potentially blowing a fuse and requiring motor replacement. By understanding these common issues, you can effectively diagnose and resolve the problem, ensuring your INFINITI FX37's cooling system operates efficiently.
When the radiator fan in your INFINITI FX37 fails to operate, it’s crucial to address the issue without delay. Ignoring a malfunctioning fan can lead to overheating, which may cause severe engine damage and costly repairs. Start by inspecting the simplest components, such as the fuse and relay, as these are common culprits that can be easily replaced. Additionally, check the coolant temperature sensor and ensure that the coolant level is adequate, as low coolant can prevent the fan from functioning properly. Electrical connections should also be examined for any loose wires or bad grounds, as these can disrupt the fan's operation. Remember, electric radiator fans have a finite lifespan, so if your fan shows signs of wear or damage, consider replacing it to maintain optimal engine performance. By taking these steps, you can prevent further complications and ensure your vehicle runs smoothly.
