Unraveling Your Car's Temperature Troubles: Know the Causes and Solutions

Imagine going for a long drive and your car engine failing in the middle of the road. Sounds inconvenient and frustrating, right? Well, it is. Having a comprehensive car insurance policy offers the safety of all-around coverage. However, sometimes things can go wrong. One such common issue is overheating.

Car overheating does not simply harm the engine but can be harmful to your whole vehicle's functioning. This is why it is always a smart choice to have a Kotak car insurance policy to deal with the compensation for such sudden accidents. Also, being aware of what causes the temperature increase can help one understand the problem. Read on.

Car heating causes

A car is made using several components, and the functioning of each component is related to one another. This means a default in one part can negatively impact the other. For instance, the improper function of a car's cooling system can affect the other parts and result in the car overheating. Now, there are some other causes as well. Let us understand them.

  1. Defective coolant

One of the major components that saves your engine from overheating is the coolant. The basic function of the coolant is to ensure that a suitable temperature is maintained in the engine. Thus, preventing temperature increase or overheating.

If the coolant is not able to function due to leakage or any other problem, this can cause cooling system issues in the vehicle, resulting in overheating.

  1. Insufficient engine oil

You may not know this, but enough supply of engine oil is also necessary to maintain the optimum health of your vehicle. Fuel is necessary for a car's lubrication as well as to maintain a good temperature. Insufficient Engine oil can overheat the engine, causing damage to your vehicle.

  1. Radiator malfunctioning

The absorbed heat of the coolant passes through the radiator. In case the radiator fans are malfunctioning, the cooling system won't perform effectively, causing engine overheating.

  1. Broken/Defective thermostat

The thermostat is an important car component that is related to the functioning of coolant, radiator, as well as valves. Any kind of defect in the thermostat can completely hinder the flow of coolant, hindering the overall cooling system and, thus, an increase in car temperature.

In addition to these, there may be other causes like broken water pumps or hoses.


To ensure you enjoy a smooth ride without any engine failure due to temperature increase, you may follow some effective tips.

  • Proper serving your car to ensure all parts are healthy and not defective.

  • Always keep a note of the temperature gauge.

  • Air Conditioning can be turned off whenever not needed.


Maintaining a suitable car temperature is important to ensure your vehicle functions best and you enjoy the smoothest rides. However, several causes can sometimes increase the car's temperature. With proper maintenance of all car components and fixing the faulty ones, you can come up with the best solution. For major damages, you can claim insurance policies. Kotak car insurance allows quick claims with zero hassle.
