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 a 2020 Dodge Journey, start with a systematic approach that prioritizes simpler checks before moving on to more complex diagnostics. Begin 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 that controls the fan, as a malfunctioning relay can also prevent the fan from activating. Next, test the fan motor directly by applying power to it; if it fails to operate, the motor may need replacement. Additionally, check the temperature sensor, which is vital for triggering the fan when the engine reaches a certain temperature. Look for any wiring issues, such as frayed wires or loose connections, as these can disrupt the fan's functionality. Finally, utilize a diagnostic scanner to identify any trouble codes that may indicate specific problems within the radiator fan system. By following this structured diagnostic approach, you can efficiently identify and address the underlying issues affecting your radiator fan.
When diagnosing why the radiator fan in your 2020 Dodge Journey has stopped working, it's essential to consider several common issues that could be at play. A faulty fan motor is often the primary culprit, as it can fail to spin, leading to overheating. Additionally, a blown fuse in the fan circuit can interrupt the power supply, preventing the fan from operating altogether. Another potential issue is a defective relay, which is responsible for sending the electrical signal to the fan; if this component malfunctions, the fan won't receive the necessary power. It's also worth checking for broken fan blades, as any damage can hinder the fan's ability to rotate effectively. Lastly, problems with the coolant temperature sensor can prevent the fan from activating at the right temperature, exacerbating overheating issues. By understanding these common problems, you can take the first steps toward diagnosing and potentially fixing the radiator fan issue in your vehicle.
When it comes to the urgency of repairing a non-working radiator fan in your 2020 Dodge Journey, the stakes are high. The radiator fan is essential for regulating your engine's temperature, preventing overheating that can lead to severe engine damage. If the fan fails, the engine may quickly reach dangerous temperatures, risking damage to vital components like the cylinder head gasket and pistons. This not only jeopardizes your vehicle's performance but can also leave you stranded due to a breakdown, resulting in costly repairs or towing fees. Moreover, delaying the repair can exacerbate the problem, leading to more extensive and expensive fixes down the line. Therefore, addressing the malfunctioning radiator fan should be a top priority for any DIY enthusiast looking to maintain their vehicle's reliability and safety. Regular maintenance and prompt repairs are key to ensuring your Dodge Journey remains in optimal condition.
