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-functioning radiator fan in your 2020 Chrysler Voyager, 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 controls the power supply to the fan. Testing or replacing a faulty relay can restore functionality. 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, as it plays a crucial role in signaling the fan to activate when the engine reaches a specific temperature. Don’t overlook the wiring connected to the fan; damaged or corroded wires can disrupt power flow. Finally, using an OBD-II scanner to check for error codes can provide insights into any underlying issues within the cooling system. By following this structured diagnostic approach, you can efficiently identify and resolve the problem with your radiator fan.
When diagnosing why the radiator fan in a 2020 Chrysler Voyager 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 cut off power, rendering the fan inoperative. Another potential issue is a defective relay, which is responsible for controlling the power supply to the fan; if it malfunctions, the fan may not activate when necessary. Furthermore, the coolant temperature sensor plays a vital role in signaling the fan to turn on; if this sensor is faulty, it may not relay the correct temperature readings, preventing the fan from engaging. Lastly, wiring issues such as damaged or corroded connections can disrupt the electrical flow to the fan, causing it to fail. Addressing these problems promptly is essential to avoid engine overheating and ensure the longevity of your vehicle. Regular maintenance checks can help identify these issues early, allowing for timely repairs and peace of mind while driving.
Addressing a non-working radiator fan in a 2020 Chrysler Voyager is an urgent matter that should not be overlooked. The radiator fan plays a vital role in maintaining optimal engine temperature by dissipating heat from the radiator. When this fan fails, the engine is at risk of overheating, which can lead to severe damage, including a blown head gasket or even complete engine failure. These repairs can be costly and time-consuming, making it essential to act quickly. Additionally, prolonged overheating can affect the performance and efficiency of your vehicle, leading to further complications down the line. Therefore, if you notice that your radiator fan is not functioning, it is crucial to diagnose and resolve the issue immediately to protect your engine and ensure the longevity of your Chrysler Voyager.
