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 first indication of a defective fan clutch is a healthy cooling system that runs below or above the normal temperature range. This is due to the fan running too fast or too slow. Also, a seized cooling fan will cause a loud roaring fan noise from under the hood every time the accelerator is pressed, and the engine will feel as if it lacks power. In this situation it would be very difficult to turn the engine cooling fan by hand, of course when the vehicle is off. Finally, if the clutch fails the fan will either turn very slowly, and not respond well to engine speed.
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-working radiator fan in your 2012 Jeep Liberty, 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, as it plays a crucial role in supplying power to the fan. A malfunctioning relay can prevent the fan from activating, so testing its functionality is essential. Next, test the fan motor directly by applying power to it; if it fails to operate, replacement may be necessary. Additionally, check the temperature sensor, which is responsible for signaling the fan to turn on at the appropriate engine temperature. A faulty sensor can disrupt this process. Don’t forget to inspect all wiring and connections for any signs of damage or wear, as compromised wiring can lead to operational failures. Finally, using a diagnostic scanner to check for error codes can provide valuable insights into any underlying issues affecting the cooling system. By following this structured diagnostic approach, you can efficiently identify and address the cause of your radiator fan's malfunction.
When diagnosing why the radiator fan in a 2012 Jeep Liberty has stopped working, it's essential to consider several common problems that could be at play. A faulty fan motor is often the primary culprit; if the motor fails, the fan will be unable to spin, leading to inadequate cooling of the radiator. Additionally, a blown fuse can interrupt the power supply to the fan, rendering it inoperative. Another potential issue is a faulty relay, which is responsible for sending power to the fan motor; if this component malfunctions, the fan will not function as intended. The coolant temperature sensor also plays a critical role in regulating the fan's operation; if it fails, the fan may not activate when necessary, risking engine overheating. Lastly, wiring issues, such as damaged or corroded connections, can prevent the fan from receiving the power it needs to operate. By systematically checking these components, you can effectively troubleshoot and resolve the issue of a non-functioning radiator fan in your Jeep Liberty.
When it comes to the non-working radiator fan in a 2012 Jeep Liberty, the urgency of repair cannot be overstated. The radiator fan is essential for regulating the engine's temperature by dissipating heat, especially during low-speed driving or when the vehicle is stationary. If the fan fails, the engine is at a heightened risk of overheating, which can lead to severe damage, including blown head gaskets and warped engine components. Such issues not only result in costly repairs but can also compromise the vehicle's performance and fuel efficiency. Therefore, it is crucial to address any signs of a malfunctioning radiator fan immediately. Ignoring this problem can lead to a cascade of failures that may leave you with a vehicle that is not only unsafe to drive but also significantly more expensive to repair. For the sake of your Jeep Liberty's longevity and your safety, prompt diagnosis and repair by a qualified mechanic are highly recommended.
