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 a non-functioning radiator fan in your 2010 Pontiac G3, begin with the simplest solutions before progressing to more complex diagnostics. Start by checking 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, inspect the relay, as it plays a crucial role in supplying power to the fan. A malfunctioning relay may need replacement. Next, test the fan motor directly by applying power to it; if it fails to operate, the motor itself may require replacement. Additionally, examine the temperature sensor, which is responsible for signaling the fan to activate when the engine reaches a certain temperature. A faulty sensor can prevent the fan from turning on. Don’t forget to inspect all wiring and connections for any signs of damage or disconnection, as these can impede power flow to the fan. Finally, using a diagnostic tool to scan for any trouble codes can provide further insights into the cooling system's issues. By following this structured approach, you can systematically identify and address the problem with your radiator fan.
When diagnosing why the radiator fan in a 2010 Pontiac G3 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, effectively shutting down the fan's operation. Another potential issue is a defective temperature sensor, which may fail to signal the fan to activate when the engine reaches a certain temperature, resulting in inadequate cooling. It's also important to check for broken fan blades, as damage can hinder airflow and cooling efficiency. Lastly, wiring issues can prevent the fan from receiving the necessary power, so inspecting the electrical connections is essential. By understanding these common problems, DIYers can effectively troubleshoot and address radiator fan issues, ensuring their vehicle remains in optimal condition.
Addressing the repair of a non-functioning radiator fan in your 2010 Pontiac G3 is not just a matter of convenience; it is a critical safety concern that demands immediate attention. When the radiator fan fails, the engine's cooling system becomes compromised, leading to a significant risk of overheating. This overheating can cause severe damage to vital engine components, resulting in costly repairs that could have been easily avoided. Signs such as broken fan blades, corrosion, or a burned-out motor are clear indicators that the fan requires urgent repair. Ignoring these symptoms can escalate the problem, potentially leaving you stranded or facing a complete engine failure. Therefore, it is essential to prioritize the repair of your radiator fan to ensure the longevity of your vehicle and maintain safe driving conditions.
