5 Typical Causes of Engine Overheating

Engine overheating could be the possible consequences of several problems including a blocked radiator, cracked cooling system, botched water pump, or a bad thermostat. Most car engines operate between 195°F and 220°F range. Any defect with these components can cause this temperature to rise beyond the normal level, leading to the overheating of your car. So in this blog, we will show you about common causes of engine overheating, engine overheating consequences, what happens when an engine overheating and how to deal with them. Let’s check it out!

Engine Overheating Consequences

Normally, a car engine will need servicing within its first five to seven years. Nevertheless, the engine in some cars can operate over 10 years without any troubles. However, it is important to maintain your car in order to safeguard your car engine. By doing this, you don’t have to worry about replacing or working on the car engine regularly. Although a car engine is produced with a long life span, it can not bear extremely high temperatures for long periods.

At such situations, the car engine can stop working, moreover the seals and the gaskets can be damaged seriously when exposing to high temperatures that they can not handle. In all cases, overheating can badly invade the car and even you have too much money, you can’t do anything to fix it. So this is why it is crucial to know the causes of engine overheating and how to deal with such a situation.

The Typical Causes Of Engine Overheating

It must be annoying when you are driving to catch an urgent meeting but suddenly steam starts spewing from under the hood, and you have to pull over somewhere. What is more terrifying is the possibility of an expensive fix because overheating could be extremely damaging for various parts in your car. Let’s find out some causes of the engine overheating:

1. A Leak In The Cooling System

The air that enters the system through the leak is one of the possible causes of engine overheating. The coolant drips through the puncture, creating space for air to get sucked in. The air takes the shape of a big bubble, known as an airlock, and occupies the top part of the system. The coolant can’t push through it to reach the engine, causing the overheating.

2. Condensed Coolant

It’s an annoying problem in cold weather, especially in those places where temperature drop below the freezing point. If the coolant is not high-quality, it can get concentrated and cause a blockage. Such a condition will result in engine overheating and damage the radiator.

3. Blockage To Coolant Circulation

It can bring about the same symptoms of the gelled coolant. Sometimes, a defected thermostat, mineral deposit, or a foreign object can block the liquid from flowing through the radiator to disperse heat.

4. Low Level Of Oil

Engine oil itself helps with the cooling process and prevents the buildup of excessive heat. In fact, the fuel removes 75% to 80% of the unused heat in the engine. It also keeps various parts properly lubricated, reducing friction and the subsequent overheating.

5. Broken-Down Water Pump

It’s one of the most frequent reasons for engine overheating. It is a component that actively takes part in maintaining coolant circulation. It can wear out or break over time, leading to the damage of the impeller that does not turn anymore.

Signals To Look For When A Car Overheats

Here are three common signals for car overheating to check out:

1. Dashboard Caveats

The dashboard can alert you when your car overheats as the dashboard temperature indicator will start to increase. Most drivers often ignore the warning signals given by the dashboard, however they are very crucial.

The dashboard will not alert you only when the thermostat of the car is broken, in all other cases, it will. Addition to it, in recent car models, if the car begins to overheat, a malfunction light will turn on to notify its driver.

2. Steam Or Smoke

Whenever you notice steam or smoke billowing from under the hood of your car, the first thing you have to do is stopping your car right away. Steam or smoke appearing under the hood is not a good signal in any case. It can illustrate other things as well, such as leaking oil burning in the engine or harmless or an overheated car. In this case, you should get your car engine inspected by a skillful mechanic in order to prevent further damages.

3. Hot Air Coming Out Of The Air Conditioner

Even though hot air from the Air Conditioner of the car doesn’t demonstrate that the car is overheating instantly, it is likely that car overheating will happen soon. Putting coolant in your car is what you can do to tackle this problem.

How To Troubleshoot Car Overheating Causes

As you already know about the issues that trigger engine overheating, you will know where to look when a temperature malfunction arises. You should check:

• The coolant system
• Level of engine oil
• Radiator
• Thermostat
• Water pump

Any trouble with these things often brings out the heat issue. The measures you can take are to:

1. Flush the cooling system when it’s dirty or at the time recommended by the manufacturer
2. Examine the cooling structure for leakage or any other fault
3. Fill up the tank or change the oil regularly
4. Inspect the radiator, thermostat, and water pump for any damage
