Why Is My Car Overheating | Reasons And Solutions

why is my car overheating

A jovial family loads the vehicle for a ride to the beach. A few hours into the journey, everything goes wrong. The car’s engine begins to smoke, forcing the family to pull over. Where does this go from here?!

This screenplay is a staple of a good number of summer horror movies, but it’s different from what you want to recreate on your next road trip. Be prepared for any situation by learning what to do if your car’s engine overheats.

Why is my car overheating

Your car can overheat for a variety of reasons, including a faulty radiator or a leak in the cooling system. The typical range for a car’s temperature is 195 degrees to 200℉. You should avoid further damage to your car if you don’t drive when the temperature gauge is above average. Let’s look at the possible causes of car overheating.

If a car overheats, what does that mean?

Your vehicle overheating can be a sign of more serious problems that may require costly repairs. The following are some examples that fall into this category:

  • One of the most common reasons for a car to overheat is a problem with the air conditioning system. Leaks can occur anywhere in the cooling system, including the radiator, water pump, hoses, thermostat and head gasket.
  • Overheating can occur if the wrong coolant is used in the vehicle or if the coolant to water ratio is not correct (50/50 is ideal).
  • Then check the coolant line for any blockages. Bayonne’s roads are full of cracks and crevices that dirt and debris can slip through and clog your radiator. This can clog the coolant line.
  • The radiator has a problem; this is a typical cause of vehicle overheating. A vehicle overheating can be the result of a variety of issues, including a blockage, a leak, or a faulty radiator fan.
  • There seems to be a problem with your car’s water pump. This is a serious problem as the water pump is responsible for circulating engine coolant through the cooling system. Possible causes of overheating are a leak or a displaced pump shaft, both of which may be present in your unit.

Why does my car overheat with a new radiator?

After replacing the radiator in your car, you may notice that it overheats for no apparent reason. This is often the result of air trapped in the cooling system.

But it is also possible that the problem is due to another aspect of your AC. Think of the water cap, thermostat, fuel pump, heating hoses, overflowing reservoir, etc.

Furthermore, according to the installation procedure, connect the temperature sensor and the cooling fan.

All the scenarios where your car can overheat although a brand new radiator is listed here.

Compressed air used for cooling

It’s easy to get air trapped in the air conditioning system if it doesn’t bleed when a new radiator is installed. This air is known to cause hot spots and lead to engine overheating.

After the radiator is in place and you’ve confirmed there are no additional issues with the cooling system, you can burp the system to release any trapped air and hopefully resolve the overheating issue.

Lack of water pressure due to a broken pump

When the water pump in your cooling system is not working properly, it restricts coolant flow, leading to engine overheating.

Damaged thermostat

A faulty thermostat is another possible explanation for your problem. Due to the limited coolant flow caused by sticking thermostats, your vehicle will overheat.

Blown head gasket

The head gasket may have cracked, causing an improper seal. In this condition, combustion fumes can easily enter the cooling system, which can lead to overheating.

A blown gasket is likely the cause if you’ve tried to remove all the air from your air conditioning system and it keeps coming back.

Reduced coolant

Also check whether the reservoir is getting enough coolant. Failure to do so will cause the air conditioning system to fail, leading to the car overheating.

Why does my car overheat at high speeds?

At high speeds, motor overheating can have several causes. There are a few common causes of this problem: a broken thermostat, a clogged radiator, or both.

A lack of coolant, a broken radiator, a defective water pump, etc.

Why does my car overheat in the cold?

Vehicle overheating is often caused by problems with the cooling system, including a clogged thermostat or coolant leak, and is most common in the winter. A leak in the cooling system causes the coolant level to drop, blocking the passages where coolant normally flows through the engine.

Why does my car overheat with a new thermostat?

There are several possible causes of overheating. A clogged radiator or heater core, faulty water pump, damaged radiator, or other coolant-related issues could be to blame if your vehicle overheats despite a new thermostat.

Solutions to overheating vehicle problems

In that case, switch from cooling to heating to exhaust the heated air. After finding a safe place to stop, contact a tow truck to take your car to a repair shop. Another thing to remember is that the hood will probably be quite hot, so you’ll have to wait for it to open.

Symptoms of engine damage from overheating

If your engine has overheated, you may notice signs such as a burning smell, fluid leaks or (in the worst case scenario) a broken engine block. An overheated engine should be checked immediately by a professional technician.

Over time, a car’s engine will naturally get hotter as it runs. To avoid costly breakdowns due to an overheating engine, your car is equipped with an automated cooling system.

Yet problems still go unreported, leading to potentially catastrophic engine overheating.


Why is my car overheating? If you suspect your engine is overheating, have it examined by a professional to determine if it needs repair or replacement. Engine damage due to overheating can be caused by the given problems. Take action quickly to prevent more damage to your car.
