Why Is My Car Overheating? – Fixing It

Have you ever asked yourself: why is my car overheating? Car engine overheating is one of the most dreadful experiences faced by car owners. In theory, it’s when a large amount of energy is emitted by the vehicle in form of heat. The combination of heat and extreme condition of the surrounding environment results in the overheating of the vehicle’s engine. Car overheating problems should be handled with all seriousness as it is capable of causing irreparable damage to the vehicle engine. 

In this article, common problems associated with car overheating will be discussed in detail.

Car overheating is a problem all vehicle drivers wouldn’t wish to encounter. It is a problem capable of stalling the engine and drastically reduces the vehicle’s power and efficiency. Below are the possible reasons behind car overheating problems. Let’s check them out!

Low Coolant Level

The vehicle coolant system is responsible for the absorption and removal of excess heat from the engine. Overheating mostly occurs as a result of low coolant level which may happen either due to the overflow of the tank or low coolant in the radiator. The coolant system of vehicles should be routinely checked to detect any problems early enough before it cause extreme damage to the entire car engine.

Defective Radiator

The tendency of vehicles to overheat is high if the radiator malfunctions. The usual problems of radiators are blockage or obstructions with particles that can easily be unblocked using a radiator flush. Also, vehicle engines experience overheating of the radiator cap. Which is responsible for pressurizing the car’s cooling system. Furthermore, if the radiator hose is constricted or leaks, the car engine will easily overheat. It could potentially cause severe damage if you don’t fix it as soon as possible.

Faulty Thermostat 

Thermostats should open at a proper temperature for easy circulation of coolant through the vehicle engine. However, a defective thermostat won’t be able to perform this important task. Which might ultimately result in overheating of the car engine.

Faulty Water Pump 

Water pump is an essential part of the cooling system of car engines. It is responsible for the smooth movement of coolant through the engine’s cooling system. A faulty water pump will be unable to move the coolant through the system. Which may cause the engine to heat up. Water pump requires a quick resolution to avoid a serious damage in the car engine.

What Should I Do When My Car Starts Overheating?

If overheating suddenly occurs while driving, the first and most important step to take is to pull the car over. Allow the engine to cool off. After a little while, proceed to check the coolant level and top it up if necessary. Also, ensure the radiator fan is turning freely and making sure the radiator hose is intact.

Is It Safe To Drive A Car After It Overheats?

Yes. As long as the engine is not damaged. However, it is advisable to allow the vehicle to cool off and have the cooling system checked before you drive. Essential parts of the cooling system like the thermostat, radiator, and water pump should be checked and adjusted where necessary to avoid a re-occurrence of overheating.  

Final words

Car overheating problems are usually cooling system issues. However, there are other reasons such as faulty water pumps, defective thermostats, and radiator issues behind car engine overheating problems. With regards to the above narratives,  a routine check for cooling system problems to avoid severe damage to the car engine is a good practice.
