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 the non-working radiator fan in your 2009 Dodge Journey, begin with a systematic approach that prioritizes simpler checks before delving into 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 is crucial for supplying power to the fan. A malfunctioning relay can disrupt the fan's functionality, so ensure it is working correctly. Next, test the fan motor directly by applying power to it; if it fails to operate, it may need replacement. Additionally, check the temperature sensor, as it plays a vital role in signaling the fan to activate when the engine reaches a certain temperature. If the sensor is faulty, it can prevent the fan from turning on. Don’t forget to inspect all wiring and connections for any signs of damage or wear, as faulty wiring can also impede the fan's operation. Finally, using a diagnostic scanner to check for any trouble codes can provide further insights into underlying issues within the cooling system. By following this structured diagnostic approach, you can efficiently identify and address the problem with your radiator fan.
When troubleshooting the radiator fan issue in a 2009 Dodge Journey, it's essential to understand the common problems that could be at play. A faulty fan motor is often the primary culprit, as it directly affects the fan's ability to cool the radiator. Additionally, a blown fuse can interrupt the power supply to the fan, rendering it inoperative. Another potential issue is a malfunctioning temperature sensor, which is crucial for signaling the fan to activate based on engine temperature. Wiring problems, such as damage or corrosion, can also prevent the fan from receiving the necessary power. Furthermore, low coolant levels can impact the fan's operation since the fan relies on coolant to help regulate engine temperature. Lastly, a defective fan relay may fail to send power to the fan motor, causing it to stop working altogether. By systematically checking these components, you can effectively diagnose and resolve the radiator fan issue in your vehicle.
When it comes to the non-functioning radiator fan in a 2009 Dodge Journey, the urgency of repair cannot be overstated. The radiator fan is essential for regulating the engine's temperature by dissipating heat, and without it, the risk of engine overheating significantly increases. Overheating can lead to severe consequences, including warped cylinder heads and blown head gaskets, which not only compromise engine performance but can also result in catastrophic engine failure. Additionally, the inconvenience of being stranded due to an overheated engine can lead to costly towing fees and repair bills. Ignoring the malfunctioning fan may seem manageable in the short term, but it can escalate into more extensive and expensive repairs down the line. Therefore, addressing the issue promptly is vital for maintaining the vehicle's health and ensuring a safe driving experience.
