Have you ever needed cool air in your Volvo, but warm air is all you feel? This is one of the problems with a faulty cooling fan module, and it can affect the quality of your rides if not taken care of. The cooling fan module helps to regulate the engine’s temperature by controlling the rotation of the fan motor.
This cooling fan module can fail for several reasons. If not addressed early, it can cause various performance issues in your car. In this article, we will address the common causes of cooling fan module failure in cars and how it affects your car.
Why Does the Cooling Fan Module Fail?
Cooling fan module failure is common with most Volvo vehicles. Here are some reasons why this is so.
- Electrical Problems: The cooling system, including the cooling fan module, is powered by electrical energy. This means that it relies on the right electrical connections for its functions. However, when these connections get affected either due to faulty wiring or blown fuses, the cooling fan module may fail to work.
- Temperature Sensor Errors: Sensors are an essential component of many car systems. Without these sensors, internal components like the engine will be unable to tell what is going on outside the car. The temperature sensors, for example, help to monitor the engine temperature, enabling the cooling fan module to perform its functions. However, if this sensor fails, then the fan module may be unable to adequately regulate the engine’s temperature.
- Low Coolant Levels: Coolant plays an essential role in engine temperature regulation; it helps by absorbing the engine’s heat. However, when the coolant levels in the engine get below optimal (mostly due to a leak in the cooling system), there is undue pressure on the cooling fan module to cover up for the limitation caused by the lack of sufficient engine coolant. Over time, this could damage the cooling fan module.
How a Cooling Fan Module Failure Can Affect Your Volvo’s Performance
Here are a few ways in which cooling fan module failures can impact engine performance in most vehicles.
- Engine Overheating: One of the major results of cooling fan module failure in any car is engine overheating. This happens simply because the cooling fan module is no longer available to regulate the engine’s temperature and remove the heat the engine produces. This high engine temperature can lead to various problems from slow performance to total failure.
- Reduced Fuel Economy: Aside from temperature regulation, the cooling fan module has other important functions such as optimizing fuel economy. When the engine runs at optimal temperature, the combustion process goes smoothly. However, when there is excessive heat generation, the engine runs harder and consumes more fuel. This then results in fuel economy problems.
- The “Check Engine” Light Illuminates: The check engine warning light is one of the early signs that suggests an engine performance problem. This warning light illuminates on your car’s dashboard once the engine control module identifies any fault that affects the normal running of the engine.
- Reduced Cabin Cooling: Lack of temperature control in your Volo’s cabin can also be a performance issue and this is possible with a faulty cooling fan module. Aside from regulating the engine’s temperature, the cooling fan module also supports the air conditioning system in most vehicles by aiding the entry of cold air into the cabin when the weather gets too warm. However, once this cooling fan module gets faulty, you may begin to experience poor cooling by the AC system.
