The cooling fan is an element of the engine cooling system, the task of which is to ensure the forced passage of air through the main radiator of the cooling system, thereby causing more intensive cooling of the antifreeze in the engine system.

The rotation of the fan is carried out by a drive.

The drive comes in three types:

  1. Mechanical - the simplest type. It is a permanent drive from the crankshaft via a belt drive. The fan starts simultaneously with the engine turning on. It is worth taking into account that this drive reduces the power of the motor, as it spends a lot of energy rotating the fan.
  2. Hydromechanical drive type, unlike the previous one, the blades are connected to the pulley using a fluid coupling.
  3. Electric - consists of a sensor, an electronic engine control unit, an engine start relay and the electric motor itself. The sensor records the temperature of the coolant in the engine. If the temperature rises above normal, the sensor transmits a signal to the electronic control unit, which in turn activates the fan relay.

Signs when a driver needs to contact a car service.

  • Increase in engine temperature
  • There is no characteristic sound of the fan operating, which is located in the engine compartment in front of the engine. 

When contacting a car service center, the main thing is to carry out diagnostics, since very often a non-working fan is a consequence of a breakdown of other elements of the cooling system.

The main reasons that can lead to fan failure

  • Natural wear and tear of the fan motor
  • Faulty temperature sensor
  • Damage to electrical wiring
  • Defective thermostat
  • Defective fan relay
  • Blown fuse

If the engine temperature rises and the fan does not work, then the following may be a temporary solution:

  • turn off the air conditioner
  • turn on the interior air blower at full power and the heater to the maximum heating position

With such actions, the antifreeze will begin to cool down in the radiator of the cabin heater; this temporary solution will help avoid engine damage in an emergency, but will not eliminate the root cause of overheating.

Four common causes for an “engine temperature” light on the vehicle and their related parts.
This fix will help eliminating

Engine Temperature Light

The engine temperature warning light basically says, “We’re overheating.” Commonly, the car might be running low on coolant. But it can also be an airflow clog-up, broken fans, or leaks.

Are you noticing the engine temperature warning light on your dashboard? This light is an essential indicator of something wrong with your vehicle. But don't worry; paying attention to your car's behavior and understanding how to communicate it with your local auto shop helps you assess the problem before it worsens.

In this article, we're going to focus on common causes of the engine temperature warning light. We'll also give you tips on communicating with a mechanic in case you seek professional assistance. So don't wait; read on and better understand your car's needs.

Overheating AC

The car is overheating after turning the air conditioning on because of a faulty coolant temperature sensor, clogged radiator, and condenser fins. Less commonly, it can be an issue with the condenser fan relay or fan control module.

A car AC overheating can be a serious issue involving different electrical parts, meaning you need to check it quickly. Failure to do so could lead to a car overheat, safety hazards, and costly repairs.

Consider the assistance of a skilled professional to diagnose and fix the car air conditioning issue. This approach helps keep your car in excellent condition, ensuring your safety. Remember, neglecting a seemingly minor issue could cause more significant problems in the future, which could have been avoided with timely attention and maintenance.
