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 2007 Jeep Compass, start with the simplest solutions before moving on to more complex diagnostics. Begin by checking 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 inspect the relay, which controls the power supply to the fan. A malfunctioning relay may need replacement to restore functionality. Next, test the fan motor directly by applying power to it; if it fails to operate, the motor itself may require replacement. Additionally, examine the temperature sensor, as a faulty sensor can prevent the fan from activating when the engine reaches the necessary temperature. Don’t overlook the wiring connected to the fan; damaged or loose connections can disrupt power flow. If these steps do not resolve the issue, it may be time to consult a professional mechanic for further diagnosis and repair. By following this structured approach, you can systematically identify and address the problem with your radiator fan.
When diagnosing why the radiator fan in a 2007 Jeep Compass 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 interrupt the power supply, effectively shutting down the fan. Another potential issue is a defective relay, which is responsible for controlling the power to the fan; if this component malfunctions, the fan may not activate when needed. It's also important to inspect the fan blades themselves, as any damage or breakage can hinder air circulation, exacerbating overheating problems. Lastly, a malfunctioning coolant temperature sensor may fail to signal the fan to turn on at the right temperature, further contributing to engine overheating. Addressing these issues promptly is essential for maintaining your vehicle's performance and preventing costly damage.
Addressing the malfunction of a radiator fan in a 2007 Jeep Compass is not just a matter of convenience; it is a critical safety concern that demands immediate attention. A non-working radiator fan can lead to severe engine overheating, which poses a significant risk of engine damage. When the fan fails, the engine may not receive adequate cooling, causing the temperature to rise beyond safe limits. This can trigger a cascade of problems, including inaccurate readings from the engine temperature sensor, which may fail to activate necessary cooling mechanisms. Furthermore, insufficient coolant circulation exacerbates the overheating issue, leading to potential engine failure. Delaying the repair can result in costly repairs and extensive damage, making it imperative for DIY enthusiasts to act swiftly. By prioritizing the repair of the radiator fan, you not only safeguard your vehicle's performance but also protect your investment from the long-term consequences of neglect.
