What Causes a Car To Overheat?

Most people know that it can be a real problem when a car overheats. But not everyone knows what causes a car to overheat in the first place. In this blog post, you'll learn what causes a car to overheat and how you can prevent it from happening.

Coolant Issues

One of the most common causes of car overheating is low or contaminated coolant. Coolant is what keeps your engine cool and prevents it from overheating. If there isn't enough coolant in your system, or if the coolant is old and dirty, it won't be able to do its job correctly. That's why it's essential to check your coolant level regularly and flush and replace it according to your manufacturer's recommendations.

A Malfunctioning Thermostat

In a nutshell, this device regulates coolant flow through your engine. If your thermostat is stuck in a closed position, the coolant won't be able to flow through your engine, and it will overheat. Conversely, if your thermostat is stuck in the open position, coolant will continue to flow even when your engine is up to operating temperature, which can also cause overheating.

Malfunctioning Radiator

If your radiator is blocked or restricted, the coolant won't be able to flow through it properly, and your engine will overheat. Several things can cause a radiator to become blocked, such as leaves and debris, a build-up of scale and sediment, or even a bent cooling fin.

Besides, a radiator can become damaged for several reasons, such as an accident or a collision. If your radiator is damaged, it may be leaking coolant, leading to overheating.

Bad Hoses

The hoses in your cooling system are responsible for carrying the coolant to and from the radiator. If they are old, cracked, or leaking, they won't be able to do their job correctly, and your engine will overheat.

It's a good idea to check your hoses regularly for signs of wear and tear. If they are more than five years old or show any signs of leaking or damage, it's time to replace them.

Several things can cause a car to overheat. The most common causes are low or contaminated coolant, a malfunctioning thermostat, a blocked radiator, and bad hoses. By checking these things regularly and taking preventive measures, you can avoid overheating and keep your car running smoothly.
