The most common reasons a 2015 Jaguar XKR radiator fan isn't working are the fan assembly, the fan clutch, or the coolant temperature sensor.
  • Fan Motor or Clutch: A faulty fan motor or a malfunctioning fan clutch can result in inadequate cooling, causing the engine to overheat.
  • Fan Relay or Fuse: A faulty fan relay or blown fuse can prevent the cooling fan from operating, leading to engine overheating.
  • Temp Sensor or Fan Control Module: A faulty temperature sensor or fan control module can cause the engine cooling fan to operate improperly, leading to overheating or inadequate engine cooling.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a 2015 Jaguar XKR radiator fan isn't working?

Common Repairs

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.

What are the steps to diagnose the non-functioning radiator fan in a 2015 Jaguar XKR?

To effectively diagnose a non-functioning radiator fan in a 2015 Jaguar XKR, start with a systematic approach that prioritizes simpler checks before delving into more complex diagnostics. Begin by inspecting the fan assembly and the fan clutch, as these components are often the culprits behind fan failure. Next, examine the coolant temperature sensor, which plays a crucial role in regulating fan operation. A straightforward method to assess the fan's functionality involves disconnecting the connector cable from the radiator temperature sensor; this will allow you to check for proper electrical connections and functionality across the three pins designated for earth, low speed, and high speed. Additionally, keep an eye on the cooling system temperature, as the Powertrain Control Module (PCM) relies on input from various sensors to manage fan operation. By following this structured diagnostic approach, you can efficiently identify the underlying issue affecting the radiator fan and take the necessary steps to resolve it.

What are the common causes for the radiator fan not working in a 2015 Jaguar XKR?

When troubleshooting a non-functioning radiator fan in a 2015 Jaguar XKR, it's essential to consider several common problems that could be at fault. Start by checking the fan assembly and fan clutch, as these components are often the primary culprits. Additionally, inspect the coolant temperature sensor, which plays a crucial role in signaling the fan to operate. Electrical issues such as a blown fuse or a faulty relay can also prevent the fan from working, so examining these components is vital. Furthermore, ensure that there are no broken wires that could disrupt the electrical flow. Low coolant levels can lead to overheating, which may cause the fan to fail to engage, so verify that the coolant is at the appropriate level. Lastly, if the fan motor is drawing excessive current due to a worn-out bearing, it may blow a fuse, indicating that the fan motor itself might need replacement. By systematically checking these areas, you can effectively diagnose and resolve the issue with the radiator fan in your Jaguar XKR.

How urgent is the radiator fan repair for a 2015 Jaguar XKR to avoid overheating?

When it comes to the radiator fan repair for a 2015 Jaguar XKR, urgency cannot be overstated. The radiator fan is essential for maintaining optimal engine temperature by effectively dissipating heat from the radiator. If you notice signs such as a rapidly rising engine temperature, coolant leaks, or the fan failing to activate when the engine heats up, these are clear indicators that immediate action is required. Neglecting these symptoms can lead to overheating, which poses a significant risk of catastrophic engine damage and costly repairs. Therefore, addressing radiator fan issues without delay is crucial not only for the longevity of your vehicle but also for your safety on the road. Taking proactive measures to repair or replace a malfunctioning radiator fan can save you from the potential hazards associated with engine overheating.
