Why is My car Overheating With a New Thermostat

If you are still wondering why your car is still overheating with a new thermostat, a lot of other things including a faulty water pump, worn belt could cause it. Apart from the fact that if your car is loosing coolant or antifreeze some other faulty components could be another reason why your car is getting over heated.

Your car could be overheating as a result of coolant leak or even a blown head gasket. However, you should check out my previous article here on cookip, titled why is my Car Overheating But it Has Coolant in it, what are 10 common causes of overheating.

In this article, i will walk you through details about why your car is still overheating even with a new thermostat. Now lets lets see details on why your car could be over heating even with a new thermostat.

 

Can thermostat cause car to overheat?

 

A new thermostat can be broken and definitely a broken thermostat can will cause your car to overheat. The thermostat in your in charge of controlling the flow of coolant, it keeps the coolant from entering the unwanted places.

The coolant is not needed inside the radiator and inside the engine, the thermostat does the work of keeping it away. Thermostat senses engine temperature and controls coolant flows through the radiator.

To check for a broken thermostat, by observing the temperature of the upper radiator hose. If you notice any significant changed in the temperature of of the radiator then you should start checking for a broken thermostat or any other possible cause of overheating.

 

Why is My Car Overheating but It Has Coolant in It

 

Overheating is a normal thing in cars. But, it can be dangerous if it occurs when the car has coolant in it.

The following causes of overheating are:

  • -Fluid leak: When fluid leaks from the radiator or engine, the coolant is no longer able to circulate properly and does not reach the lower parts of the engine. This causes overheating and possible damage to other components.
  • -Coolant leak: If a coolant pipe or hose is damaged, coolant will drain into the radiator, causing a buildup of pressure that can cause an overheat or even an engine failure.

Can Low Coolant Cause Overheating

 

Low coolant prevents the engine from overheating, but it is a dangerous condition that can cause a fire.

This condition can be caused by a number of factors, including:

  • – The radiator cap is not tight enough and coolant is leaking out.
  • – The radiator clamps are loose or poorly attached to the radiator.

Overheating is a common issue in today’s vehicles. It can be caused by many factors, but one of the main causes is low coolant.

If you notice your car is overheating, it’s important to have your car checked by a mechanic as soon as possible to prevent any serious damage or injuries. Overheating can lead to engine damage and even injuries if not treated properly.

What to Do After Changing Thermostat

 

One of the most common things people do in a new home is change the thermostat. However, it’s not always easy to figure out what temperature to set it to. There are many factors that go into the decision like how cold or hot the house is, what type of heating system you have, and your climate.

The following are some helpful tips for changing your thermostat:

  • -Check your HVAC unit for instructions on how to adjust your thermostat.
  • -If you have a gas furnace, check with a professional before adjusting the temperature settings.
  • -If you have an electric furnace, make sure that there aren’t any wires or other elements near where you want to set up your thermostat.

 

Can a Bad Thermostat Cause Overheating

 

Overheating is a serious concern for homeowners and can be caused by a number of factors. A thermostat can help prevent overheating by turning up the heat when it gets too cold and cooling down when it gets too hot.

A thermostat is an electronic device that controls the temperature of heating or cooling systems in buildings. It works by measuring the temperature inside and outside, then adjusting the system to maintain a desired temperature.

When people think about their thermostats, they often think about how much energy they use to keep their home at a comfortable temperature. But there are other reasons why you should think about your thermostat as well, such as safety and comfort.

 

3 Reasons Your Car Could Be Overheating

 

The cooling system in your cars removes excess heat from the engine, maintains a constant engine temperature, increases temperature of a cold engine quickly and warms the passenger compartment. If the cooling system in your car is overheating then this 3 things could be causing it.

  • Leaking Coolant or antifreeze

Leaking coolant or antifreeze is one of the first pointers of overheating car. Coolant is a mixture of ethylene glycol and water 50/50, it is in charge of stabilizing the car’s temperature.

If your car cooling system is leaking coolant then the level of the coolant will reduce thereby causing your car to overheat. Sometimes there could be no visible leaks of antifreeze but that doesn’t mean that your car is not loosing coolant through other means.

  • Improper Circulation of Coolant

Normally, the coolant is supposed to move continuously circulate and push through the engine by the water pump. The coolant flows inside the engine through water jackets throughout the engine.

The coolant flows inside the engine through these, absorbing the engine’s heat. It then travels through hoses to the radiator, where it cools down.

If anything happens and coolant in your car does stops following the normal route of flow your can would definitely over heat. Coolants are said to evaporate or get clogged over time, so even if you car might not be leaking coolant it can still get over heated.

  • Coolant Hoses Need Replacing

The hoses that circulate your coolant can become eroded, clogged, or detached over time. If this happens they may need to be reattached, cleaned out, or replaced entirely for coolant to flow normally through the system.

  • A Broken Thermostat

The job of the thermostat is to controls the flow of coolant through the needed place in the car. It is more like a portal through which the cooling system circulate coolant around the car.

The thermostat uses a spring operated poppet valve to circulate the coolant around. The valve is closed when the engine is cold thereby blocking the flow of coolant until when temperature is high in the engine.

 

3 signs of a bad thermostat

 

 

If your car thermostat is faulty or you cannot not just know by looking at it. Here are the 3 most prominent signs and indicators of a bad thermostat.

  • Constant overheating of engine and high temperature gauge reading

The temperature gauge in your car is connected to cars computer, it’s job is to warn you when your car is overheating. Whenever the temperature in your cars start to raise above normal, it starts reading red within first 15 minutes of running your vehicle.

This sign is a to show your that the thermostat in your car is not working properly or is bad. It can also mean that your have a blockage in one of the circulating systems valve or your car might be leaking coolant or antifreeze.

  • Unstable Temperature change

unstable fluctuation in temperature is another sign of a bad thermostat. This happens as a result of wrong readings represented by the thermostat’s meter.

Unstable temperature can lead to a poor engine performance. In this case you may see the temperature abnormally low at one point and shortly after climb to an abnormally high level.

  • Leaking coolant from car when parked or around the thermostat

Generally leaking of coolant or antifreeze leads to shortage of coolant in the car, thereby leading to overheating. This can be noticeable in a variety of locations, but most commonly around the thermostat housing. This can eventually cause other coolant hoses to leak as well resulting in coolant often times leaking on the ground under your vehicle.

 

Conclusion

 

If you could remember a coolant is a a substance that protects the engine from overheating, it is also called antifreeze. An antifreeze or coolant serves a lot of purpose including Prevention of winter freeze up, prevents rust and corrosion, lubricates water pump, cools the engine.
