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 2019 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 prevent the fan from operating. 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 often resolve the problem. Next, test the fan motor directly by applying power to it; if it fails to turn on, 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; inspect for any signs of damage, loose connections, or corrosion that could disrupt power flow. Finally, using a diagnostic scanner to check for any Diagnostic Trouble Codes (DTCs) can provide further insights into the cooling system's performance and help identify any underlying issues. By following this structured diagnostic approach, you can efficiently determine the cause of the radiator fan malfunction and take the necessary steps for repair.
When facing issues with the radiator fan in a 2019 Dodge Journey, it's crucial to understand the common problems that could be at play. A faulty fan motor is often the primary suspect, as it can fail to operate, leaving the engine vulnerable to overheating. Additionally, a blown fuse in the fan circuit can interrupt the power supply, effectively shutting down the fan's functionality. Another potential culprit is a defective relay, which is responsible for controlling the power to the fan; if this component malfunctions, the fan may not receive the necessary signals to operate. Furthermore, the coolant temperature sensor plays a vital role in regulating the fan's operation; if it fails, the fan may not activate when the engine reaches its optimal temperature. Lastly, wiring issues can also impede the fan's performance, as damaged or corroded connections can disrupt the electrical flow. By systematically checking these components, DIYers can effectively diagnose and resolve the radiator fan issue, ensuring the engine remains cool and operates efficiently.
When dealing with a non-functioning radiator fan in a 2019 Dodge Journey, the urgency of addressing this issue is paramount to avoid severe engine damage. The radiator fan is vital for maintaining the engine's optimal temperature; without it, the risk of overheating increases significantly. Overheating can lead to critical problems such as warping of the cylinder head, damage to the head gasket, and even complete engine failure if not addressed swiftly. Symptoms like a rising temperature gauge, steam from the engine bay, or a strong coolant smell indicate that immediate action is necessary. Neglecting these warning signs can result in escalating repair costs and unsafe driving conditions. Therefore, it is essential to prioritize the repair of the radiator fan by consulting a qualified mechanic to ensure the vehicle remains safe and operational, ultimately protecting the engine from further damage.
