Causes of engine overheating

Motor overheating can be caused by various factors. One of the most common is a lack of coolant, which is essential to maintain proper engine temperature. If the coolant level is low or dirty, the engine can quickly overheat. Another common cause is a faulty thermostat, which regulates the engine's temperature. If the thermostat is not working properly, it can cause overheating. Additionally, a broken or worn fan belt can prevent the engine from cooling properly, which can also lead to overheating.

Consequences of engine overheating

Engine overheating can have serious consequences if not addressed in time. One of the main consequences is the damage to the head gaskets. When the engine overheats, the head gaskets can warp or break, which can lead to coolant and oil leaks. Also, overheating can damage pistons and connecting rods, affecting engine performance and may require expensive repairs. In extreme cases, prolonged overheating can even cause the motor to burn out, requiring a complete replacement.

How do you know if the engine is overheated?

It is important to be able to identify the signs of an overheating engine so that you can act quickly. Some common symptoms include increased temperature on the dash gauge, white or gray exhaust smoke, burning odors coming from the engine, and unusual noises. If you notice any of these symptoms, your engine is likely overheating and you should take immediate action to prevent further damage.

What to do in case of engine overheating?

If you find yourself in the situation of an overheated engine, it is important to act quickly and safely. Here are some tips to help you:

  1. Stop the vehicle in a safe place and turn off the engine.
  2. Wait for the engine to cool down before opening the hood. Never try to open it if it's hot, as you could seriously burn yourself.
  3. Check the coolant level. If it's low, you can add more as long as the engine is cold. If you don't have coolant on hand, you can temporarily use distilled water.
  4. Visually check for broken or worn fan belts. If you encounter any problems, it is advisable to call a roadside assistance service or take the vehicle to a specialized workshop.
  5. Once you have performed these actions, you can try starting the engine again and see if the temperature remains stable. If the problem persists, it is advisable to seek professional help.
