In a car, the thermostat is located between the engine and radiator. Its purpose is to regulate the flow of coolant through the engine, ensuring that it doesn’t get too hot or too cold.
The thermostat consists of a sealed housing and a valve. The housing is filled with a liquid that expands and contracts as it heats up and cools down. This expansion and contraction open and close the valve, regulating the flow of coolant.
The thermostat is designed to open at a certain temperature, allowing coolant to flow through the engine and keeping it from overheating. When the engine is cold, the thermostat stays closed, preventing coolant from flowing through until the engine warms up.

What Happens When Your Car Thermostat Goes Bad?
A car thermostat is a small, but important, component of your vehicle’s cooling system. Its job is to regulate the flow of coolant, ensuring that it circulates through the engine long enough to absorb heat, but not so long that it overcools the engine.
When a thermostat goes bad, it can cause a few problems.
The most common symptom is engine overheating. This can happen because the thermostat is stuck in the “open” position, causing coolant to circulate too quickly and preventing it from absorbing enough heat.
Alternatively, the thermostat may become stuck in the “closed” position, causing coolant to build up in the engine and overheat.
Either way, a malfunctioning thermostat can lead to serious engine damage if not fixed promptly.
Can You Drive With A Bad Thermostat?
A bad thermostat can certainly affect your car’s performance, but whether or not you can drive with a bad thermostat depends on the severity of the issue.
If the thermostat is only slightly damaged, it may not cause any major problems and you should be able to drive without issue.
However, if the thermostat is significantly damaged, it can cause your engine to overheat. This can lead to serious engine damage, so it’s best to avoid driving if your thermostat is in bad shape.
In general, it’s always best to get your car checked out by a professional if you think there may be an issue with the thermostat. That way, you can be sure that your car is safe to drive and won’t end up causing any costly repairs down the road.
What Causes A Thermostat To Fail?
There are a few different things that can cause a thermostat to fail. One of the most common causes is age. Over time, the internal parts of the thermostat break down or become corroded, making it less accurate. Dust and dirt can also build up inside the thermostat, interfering with its ability to accurately sense temperature.
In some cases, a thermostat may fail due to a power surge or other electrical issue. Finally, poorly installed or maintained thermostats can also experience problems. If a thermostat is not properly calibrated, it may not be able to accurately control the heating or cooling system.
How To Know If Your Thermostat Is Bad In Your Car?
Most car thermostats these days are pretty reliable. But like any mechanical device, they can go bad from time to time. So what exactly happens when your car thermostat goes bad?
One of the most common symptoms of a bad car thermostat is overheating. If your car starts to run hot more frequently than usual, it could be a sign that the thermostat is sticking in the open position. This can cause coolant to circulate through the engine too quickly, resulting in overheating.
Another symptom of a bad car thermostat is poor fuel economy. If your car’s thermostat is stuck in a closed position, it can restrict the flow of coolant through the engine. This can cause the engine to run hotter than it should, which can lead to decreased fuel economy.
If your car has either of these symptoms, it’s best to have it checked out by a mechanic as soon as possible. A bad thermostat is usually an easy and inexpensive fix, so there’s no need to wait until it causes more serious problems.
Can A Bad Thermostat Cause Your Car To Overheat?
A faulty thermostat can actually cause your car to overheat. If the thermostat gets stuck in the “open” position, it will constantly allow coolant to flow through the engine, preventing the engine from reaching its optimum operating temperature. As a result, the engine will have to work harder than usual to maintain its correct temperature, leading to increased wear and tear and eventually causing the engine to overheat.
So if you notice that your car’s temperature gauge is creeping into the red zone, it might be time to check your thermostat.
Can A Bad Thermostat Cause A Check Engine Light?
A bad thermostat can cause engine overheating by preventing the coolant from flowing properly. This can lead to serious engine damage, so it’s important to get the problem fixed as soon as possible. If you suspect that your thermostat is causing your check engine light, be sure to have your car checked out by a professional.
How Much Does It Cost To Replace Your Thermostat?
If your thermostat is on the fritz, you may be wondering how much it will cost to replace it. The good news is that thermostats are relatively inexpensive, and you should be able to find a replacement for under $100. Installation costs will also vary depending on the complexity of the job. In most cases, you should be able to install a new thermostat yourself without too much trouble. However, if you’re not confident in your DIY skills, it’s always best to hire a professional. Overall, the cost of replacing a thermostat should be between $150 and $350.
If you’re experiencing any of the common symptoms of a bad thermostat – overheating or poor fuel economy – have your car checked out by a mechanic as soon as possible. A faulty thermostat can cause a lot of problems, so it’s best to catch the issue early on.
Replacing a car thermostat is usually an easy and inexpensive fix, so there’s no need to wait until it causes more serious problems.
