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 Pontiac G6, begin with the simplest solutions to save time and effort. Start by checking the fuse and relay associated with the cooling fan; a blown fuse is often the culprit and can be easily replaced. Next, inspect the fan assembly and the fan clutch, as these components can wear out or become damaged over time. Pay close attention to the coolant temperature sensor, which plays a crucial role in fan operation. If these initial checks do not resolve the issue, examine the fan motor and wiring for any signs of damage or corrosion, as these can lead to malfunction. Additionally, ensure that the fan connector is secure and free from debris, as a faulty connection can increase resistance and hinder performance. By following this diagnostic approach, you can systematically identify and address the root causes of radiator fan problems, ensuring your Pontiac G6 runs smoothly and efficiently.
When troubleshooting radiator fan issues in a Pontiac G6, it's essential to understand the common problems that can arise. One frequent culprit is a blown fuse or a malfunctioning relay, which can disrupt the power supply to the cooling fan, leading to overheating. Additionally, the fan assembly itself may develop faults over time, preventing it from spinning properly. Another critical component to examine is the fan clutch; if it fails, the fan may not engage as needed, compromising cooling efficiency. The coolant temperature sensor (CTS) also plays a vital role, as a defective sensor can fail to signal the fan to activate, resulting in overheating. Furthermore, the fan control module is responsible for regulating fan operation, and any malfunction here can lead to erratic fan behavior. Lastly, it's crucial to inspect the wiring and electrical connections for any signs of wear or damage, as faulty wiring can impede the fan's performance. By being aware of these common issues, DIYers can systematically diagnose and address radiator fan problems in their Pontiac G6, ensuring optimal engine cooling and performance.
When the radiator fan in your Pontiac G6 is not functioning, it’s crucial to address the issue promptly to avoid serious consequences. A malfunctioning fan can lead to overheating, which may cause severe engine damage, resulting in expensive repairs or even complete engine failure. Additionally, if the fan assembly, fan clutch, or coolant temperature sensor is at fault, ignoring these components can exacerbate the problem, leading to further complications down the line. Issues with serpentine belts or a blown fuse may seem minor, but they can disrupt the entire cooling system, putting your vehicle at risk. Moreover, if the fan motor is compromised, it may freeze and fail to operate, leaving your engine vulnerable to overheating. While temporary fixes, like disconnecting the coolant temperature sensor, might provide a short-term solution, they can lead to inaccurate temperature readings and constant fan operation, which is not ideal. Therefore, it’s essential to diagnose and resolve the underlying issues with your radiator fan as soon as possible to ensure the longevity and safety of your Pontiac G6.
