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 diagnose the non-functioning radiator fan in your 2012 Jeep Wrangler, start with the simplest solution by checking the cooling fan fuse located in the Totally Integrated Power Module (TIPM) under the hood. This is a straightforward task that can quickly reveal if a blown fuse is the culprit behind the fan's failure. If the fuse appears intact, consider the possibility that the fan may have been locked up temporarily; in such cases, replacing the fan could be necessary. By following this methodical approach, you can efficiently identify the issue and determine the appropriate next steps for repair, ensuring your vehicle's cooling system operates effectively.
When dealing with a non-functioning radiator fan in a 2012 Jeep Wrangler, it's essential to consider several common problems that could be at play. One of the primary culprits is a faulty fan motor, which may require replacement to restore the fan's operation. Additionally, a blown fuse in the fan circuit can interrupt power, so checking and replacing any blown fuses is a straightforward first step. Another potential issue is a malfunctioning relay, which can prevent the fan from receiving the necessary signals to operate; replacing the relay might be necessary. Furthermore, the coolant temperature sensor plays a critical role in fan activation; if it is not functioning correctly, it may lead to incorrect temperature readings, causing the fan to remain inactive. Lastly, inspect the wiring for any damage or loose connections, as these can disrupt the electrical flow to the fan. By systematically addressing these common issues, you can effectively troubleshoot and potentially fix the radiator fan problem in your Jeep Wrangler.
Addressing a non-functioning radiator fan in a 2012 Jeep Wrangler is of utmost urgency, as it directly impacts the engine's ability to maintain a safe operating temperature. The radiator fan is essential for dissipating heat generated during engine operation; without it, the risk of overheating escalates significantly. Overheating can lead to severe engine damage, including warped cylinder heads and blown head gaskets, which can result in costly repairs or even complete engine failure. Furthermore, neglecting this issue can adversely affect other components, such as the water pump and thermostat, compounding the risk of overheating. Therefore, it is crucial for DIY enthusiasts to prioritize the repair of a malfunctioning radiator fan to ensure the vehicle's optimal performance and longevity, safeguarding against the potential for extensive and expensive damage.
