One problem you do not want occurring repeatedly in your Volvo is overheating, be it in the engine, radiator, or gasket area. Central to preventing this from happening, the cooling system is put in place to dissipate immense heat that can cause overheating during the car movement.
A major part of this cooling system is the electric cooling fan driven by a module. This module is a subset of the car’s electrical system responsible for monitoring and regulating the fan speed to minimise power loss from the battery and maximise fuel consumption. With the help of designated temperature sensors, the cooling fan module is able to perform its function. And, like other parts of the cooling system, the cooling fan module is also prone to fail over time. It is the driver’s responsibility to know how to read the car’s cooling system behaviour and know when to change the fan module.
How To Know a Failed Volvo Cooling Fan Module
Driving without a properly functioning cooling fan module can be detrimental to Volvo car cooling systems and general car health. These tips will help drivers know when the module is failing and there is a need to take prompt action.
- Overheated engine: Since the major function of the fan being powered by the module is to reduce heat in the engine area, its failure will make the engine temperature rise consistently. This, in the long run, can cause an engine knock. Your Volvo will notify you of an overheated engine on your dashboard through the temperature gauge.
- Inoperative fan: One of the most common signs of a faulty cooling fan module is the inability of the fan to blow air. Because the cabin Air conditioner (AC) is connected to the faulty module, the fan will not move at all. The cabin will most likely be inhabitable as there would be a lot of warm and stuffy air, especially in summer.
- Intermittent fan operation: The cooling fan is designed to begin operation only when the engine temperature becomes high. A failed module could make the fan run continuously even when the engine is cool or completely turned off. Also, the fan would run sporadically or at certain temperatures when the cooling fan module has failed.
- Annoying Noise: Although a cooling fan making a squeaking or grinding noise when it runs can be caused by the presence of dirt in the fan passage, it can also be attributed to the effect of a failed cooling fan module.
- Electrical problems: If the cooling fan module on your Volvo is not working, you might notice a constant drain on the car battery or the headlights getting dimmer than usual. This is because the failed module is sucking a lot of power from the battery in a bid to work.
- Engine light coming on: A failed cooling fan module will trigger the check engine light on your Volvo dashboard. This is because the vehicle’s computer system is detecting an error and is alerting you to the problem.
- Misfiring engine: A subtle sign to get your cooling fan module checked is when your car engine keeps misfiring or you experience rough idling while accelerating. This is because the engine is not getting enough air to suppress the heat it produces.
How to Fix a Volvo’s Cooling Fan Module Failure
The Volvo cooling fan module can fail as a result of a faulty electrical connection, bad ground wiring, damaged clutch assembly, and faulty temperature sensors. This is why it is best to always address its failure at an early stage to avoid damage to other parts of the car and overspending.
- Check electrical connections and power supply: Ensure that wire connections from the battery to the module are free of corrosion and damage. Also, make sure the cooling fan module is receiving enough power by checking the fuse and relays.
- Consult our professional auto mechanics: Schedule an appointment with our certified auto shop for a proper diagnostic check on your Volvo cooling fan module. With the appropriate tools, we will test the fan module and temperature sensors, and carry out necessary repair actions.
