What Causes Cars To Overheat

There are several factors that can lead to an overheated car engine. The most common causes include:

  • Low Coolant Levels: If there’s not enough coolant in the system, it won’t be able to absorb and regulate heat properly, leading to an overheated engine.
  • Clogged Radiator: If the radiator is blocked by debris or rust, it won’t be able to release heat properly and can cause an engine to overheat.
  • Faulty Thermostat: A faulty thermostat can prevent an engine from reaching its optimal operating temperature and cause overheating.
  • Leaking or Broken Hoses: Leaks or breaks in the car’s hoses can cause coolant to escape, leading to an overheated engine.
  • Faulty Water Pump: A faulty water pump won’t be able to circulate coolant properly and can lead to an overheated engine.

Warning Signs The Your Vehicle Is Getting Too Hot

There are several warning signs that can indicate that your vehicle is getting too hot:

The temperature gauge in the dashboard is reading higher than normal. If the needle on the gauge is nearing the red zone, it means that the engine temperature is high and should be addressed immediately.

You may smell a burnt odour coming from the engine or exhaust system. This is a sure sign that your vehicle is overheating.

Your vehicle’s cooling fan may be running more often than usual, indicating that it is working hard to keep your engine cool.

You may see steam or smoke coming from under the hood of your car. This is a sign that the engine is extremely hot and should be addressed as soon as possible.

Your vehicle may feel sluggish or have reduced power, indicating that it needs to cool down in order to perform properly.

Risks of Driving With An Overheated Engine

Driving with an overheated engine can be dangerous. If the car isn’t properly cooled down, it can cause severe damage to the engine and other components that could lead to a costly repair bill.

In addition, driving with an overheated engine can lead to breakdowns, risk blowing the head gasket or other parts of the engine and may even cause a fire if the situation gets too extreme. In these extreme cases, you will need to call a car removal service.
