Wondering why your Volvo’s engine might be running a little hot these days? Well, if you have observed some changes in your vehicle’s engine temperatures, or heard some sounds that do not seem usual, then there might be something wrong with the cooling fan module of your Volvo. This small device regulates when and how the cooling fan should run. Its main function is to switch on the fan when the engine heat starts to rise and turn it off after some time so that your engine can remain at optimum running temperature. The module plays a vital role in maintaining the temperatures of your engine, particularly during aggressive driving by controlling the amount of air getting to the radiators. If this system fails then the engine heat can build up very fast and cause a lot of problems.
Now, let’s look at how you can diagnose and fix this problem, and where you should go if you want a professional to repair it.
Diagnosing a Cooling Fan Module Failure
- Check Fan Operation: Start your Volvo and then let it run for several minutes. If the cooling fan does not work when your engine temperature becomes high then the fan module is most probably damaged.
- Listen for Noises: One should listen to any strange noises or sounds that come from the fan. A grinding or a whirring sound could mean that the fan is having a hard time trying to turn, and this may suggest a failing module.
- Scan for Error Codes: An OBD-II scanner can be used to look for the presence of codes that point to the cooling system or the fan module.
What Should I Do If My Vehicle’s Cooling Fan Module Is Not Working?
- Replace the Module: If the problem is confirmed to be a faulty module, then, the module will require replacement. This repair is one of the simplest jobs a professional mechanic can do to make sure that the fan is operating correctly again.
- Inspect Cooling System: The rest of the cooling system should also be checked while the fan module is being attended to. This will help to avoid other related problems such as a clogged radiator or a leaking coolant that contributes to further overheating. Always ensure all repairs are done by a certified mechanic.
What Happens If the Cooling Fan Malfunctions in Your Volvo?
When the cooling fan module is faulty, the engine will start heating up, and this can cause other problems. Overheating can lead to serious engine malfunctions such as head gasket failure, worn pistons, or, in some cases, a damaged radiator. All of these parts are essential to the health of your Volvo’s engine, and repairing them can be very expensive.
If the fan module is not properly functioning your Volvo will not be very efficient especially when accelerating in traffic or during summer because the cooling system is not efficient enough.
Is It Safe To Drive Your Car While The Cooling Fan Module Is Bad?
Well, as much as one might be tempted to drive with a bad cooling fan module, this is not a wise thing to do. Driving with a failing cooling fan can easily cause the car to overheat and this will lead to dire and costly damage to the engine. If the temperature light starts flashing or you notice steam coming out from under the hood of your Volvo, then it is probably time to get your car towed to a mechanic.
