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 troubleshooting radiator fan issues in your INFINITI G25, it's essential to adopt a systematic diagnostic approach that begins with the simplest solutions before progressing to more complex ones. Start by checking the fuse associated with the radiator fan; a blown fuse is a common and easily fixable issue that can prevent the fan from operating. If the fuse is intact, inspect the wiring and connectors for any signs of damage or corrosion, as these can disrupt the electrical flow necessary for the fan to function. Next, assess the coolant level and ensure it is at the recommended level, as low coolant can lead to overheating. Additionally, clean the radiator fins to remove any debris that may obstruct airflow, which is crucial for effective cooling. If these steps do not resolve the issue, consider bleeding the coolant system to eliminate any air pockets that could be causing overheating. By following this structured approach, you can efficiently diagnose and address radiator fan problems, ensuring your INFINITI G25 runs smoothly and remains cool.
When troubleshooting a non-functioning radiator fan in your INFINITI G25, it's essential to understand the common problems that could be at play. Start by examining the fan assembly itself, as physical damage or motor failure can prevent it from operating. The fan clutch is another critical component; if it’s malfunctioning, it may not engage the fan when needed. Additionally, the coolant temperature sensor is vital for regulating fan operation, so ensure it’s functioning correctly. Don’t overlook the serpentine belts, as wear and tear can lead to insufficient power being delivered to the fan. Electrical issues are also common culprits; check the fuses and relays for any signs of damage, and inspect wiring for loose connections or pinched wires. By systematically checking these components, you can effectively diagnose and address the issues with your radiator fan, ensuring your vehicle maintains optimal engine temperature and performance.
When the radiator fan in your INFINITI G25 fails to operate, it is crucial to address the issue promptly to avoid potential overheating and engine damage. A malfunctioning fan can stem from various causes, including a faulty fan assembly, a blown fuse, or a defective coolant temperature sensor. Ignoring these symptoms can lead to increased engine temperatures, which may result in costly repairs or even complete engine failure. Additionally, a bad relay or damaged wiring can exacerbate the problem, making it essential to conduct a thorough inspection of the electrical components associated with the fan system. If the fan motor itself is worn out, it may draw excessive current, leading to further electrical issues. Therefore, diagnosing and resolving the radiator fan problem not only ensures the longevity of your vehicle but also safeguards your safety on the road. Taking immediate action can prevent more severe complications down the line, making it a priority for any DIY enthusiast.
