BMW X5 Fans and Kits
The BMW X5’s radiator fan is important for its ability to keep the motor at a normal operating temperature. It also works as part of the vehicle’s air conditioning system. You can find a variety of BMW X5 fans and kits and learn more about them here.What does the BMW X5 SUV radiator fan do?
The radiator fan is mounted in front of the radiator and behind the bumper cover of the BMW X5. It forces air through the radiator and A/C condenser unit, cooling the antifreeze that flows through the radiator and the refrigerant that flows through the condenser. In this way, it helps to dissipate heat from the BMW’s motor and from the A/C system.What causes the BMW X5 radiator fan to stop working?
- Obstructed fan blades: The blades can be damaged or foreign objects can jam them. In either case, the fan can be prevented from running.
- Thermostat switch: If the thermostat that triggers the fan malfunctions, the fan could run at the wrong time, fail to run at all, or run intermittently.
- Electrical fault: A fault somewhere in the electrical wiring and connectors that powers and controls the fan can cause it to stop working.
- Faulty motor: The fan’s motor can also fail mechanically.
- Overheating: Your BMW’s motor may run hot or overheat, especially in slow moving traffic.
- Check engine light: The check engine light will turn on if the motor begins running hot.
- Weak air conditioning: The condenser also uses air flow driven by the radiator fan, so a faulty fan will impact the BMW’s air conditioning.
When an electrical fault is suspected in the vehicle but can’t be located, it can be simpler to test the fan’s motor to be sure it is not the problem. Remove the fan assembly from the BMW SUV and place it on a workbench. Locate a 12-volt power source such as a battery and a pair of test wires. Then, follow these steps:
- Clip the test wires onto the power source’s positive and negative posts.
- Determine the power and ground pins in the fan’s electrical connector. Connect the positive test wire to the power pin.
- Connect the negative test wire to the fan’s ground pin.
- If the motor runs, then it doesnt need to be replaced. If it doesn’t run, then it’s faulty.
