Why Is Your Engine Overheated And What To Do?

You’ve been looking forward to the warmer weather that summer offers, but although you may like soaking up the rays, your car’s engine does not. Excessive heat can cause your engine to overheat, putting a stop to your holiday plans and putting your car in the Truck engine repair service for a costly repair.

Who wouldn’t be irritated and worried if they noticed smoke coming from beneath the hood while driving in the summer? Overheating engines may and do happen, and if the proper measures and procedures aren’t done, the damage can be irreversible. Overheated engines can cause damage and sabotage your travel.

An overheated engine is one of the most dangerous problems your automobile may face. If the motor becomes too hot, it might distort and shatter, resulting in irreversible damage and the need for clutch replacement services.

Don’t wait for the temperature warning light to illuminate before taking action. Read on to find out what causes your engine to overheat, how to diagnose overheating engine, what to do if it does, and what precautions you can take to guarantee that your engine stays cool and avoid automobile engine repair all summer.

How Do I Know if My Car’s Engine is Overheating?

If your engine is overheating, there are two unique symptoms of engine overheating to look for.

  1. First and foremost, on your instrument panel, a malfunction warning light (often known as an “idiot light”) will begin to glow. The warning is usually foreboding and red or yellow. Its purpose is to draw your attention to the fact that you must respond quickly.
  2. The plume of white or light grey vapor that emanates from the leak in your cooling system is another symptom that your engine is overheating. It can be difficult to notice while driving since it follows behind your vehicle as it travels forward, but it seems your automobile is producing its fog at a stoplight.

What, on the other hand, causes an engine to overheat? Below, we’ll go through some possible causes.


As we previously said, the engine in your Chevy generates a tremendous quantity of heat. The cooling system aids in the removal of much of the surplus heat, with coolant performing much of the job. It collects heat from the engine before being cooled down in the radiator. It returns to the machine once it has lost the heat.

As a result, if you don’t have enough coolant in your cooling system, it won’t perform as efficiently. The engine’s temperature will rise because of this.

We recommend that you check the coolant levels frequently since it’s simple to do so when checking your oil or replacing your wiper fluid. If you’re losing coolant due to a leak, you should obtain an examination so specialists can figure out where the leak is coming from.


The thermostat controls the coolant flow. The thermostat valve remains closed when your engine begins, and the coolant does not flow.

The valve will open when the engine reaches operating temperature, and coolant will start to flow through the machine. A defective thermostat may remain closed even while the engine is heated, causing overheating to occur fast.


Coolant is circulated through the cooling system via the water pump. It was given this name since coolant used to be only water. Coolant is now a combination of water and antifreeze, although the original term has survived.

Even if your coolant levels are good, a defective water pump might cause coolant to circulate inefficiently or fail to circulate altogether, resulting in an overheated engine.


The radiator is where the coolant, in a sense, loses its cold. The coolant circulates via the radiator’s tubes. The heat from the liquid is collected by fins attached to these tubes, and the heat is moved away by air passing over the radiator. It’s possible that if the radiator has been physically damaged in an accident, it won’t be able to perform this as well.

In addition, the radiator cap is designed to maintain pressurization in your cooling system. If the lid is destroyed, the coolant may boil away and flee the system rather than being adequately cooled.


The air that travels over the radiator assists in removing the heat that the fins have absorbed from the coolant, but this only happens when your automobile is moving. As a result, when your car comes to a complete stop, the radiator fan will activate. This fan circulates air over the radiator. If it’s broken, your car may start to overheat while idling, then cool down as you get going.


Your vehicle’s head gasket keeps the engine block and cylinder head apart. If it blows, coolant and oil might enter the combustion chamber and cooling system, respectively. This can result in a visible coolant leak, but it can also result in reduced coolant levels without a leak. From the exhaust pipe, you may observe milky-white oil and white smoke.

What Should I Do If My Car Gets Too Hot?

What to do when car overheats?

So, if your engine overheats, then how to fix an overheated engine? First and foremost, you should be aware that driving for more than a short distance while the engine is overheating might cause catastrophic harm. The following are two immediate actions to take:

  1. Turn off the air conditioning in your vehicle.
  2. Turn on the car’s heating and turn up the fan to the maximum.

The reasons behind this are straightforward. The air conditioning adds to the burden on the cooling system, resulting in a rise in temperature. The car’s heater, on the other hand, is an internal radiator through which the vehicle’s coolant circulates. Turning it on can assist in maintaining the engine’s optimum temperature range and you might not need clutch replacement services.

Conclusion: Why Is Your Engine Overheated?

Do not attempt to drive farther if your car is overheated. Pullover to the side of the road, stop driving and turn off the engine. There are steps that may be performed to analyze any faults, but having the car towed to your local truck engine repair service station is the best option.
