Replacement of a thermostat is one of the most simple things you can do on your car.

Because even if you don’t know anything about cars, you should be able to do it without any problems.

How to fix a stuck thermostat that is closed or open? Then this post is for you. We talk about how long you can drive with the thermostat open; how much it costs to replace a thermostat in your car, and how to quickly and easily fix a stuck thermostat. Identifying a Bad Thermostat and Its Signs in a Car

How Long Can You Drive with Thermostat Stuck Open?

The thermostat’s job is to keep the engine at a safe temperature. Engineers have made modern cooling systems so that they can remove more heat from the engine than it can put out. This is done by running water through the engine and radiator.

Air that passes through the radiator moves heat from the engine to the outside world.


In a well-functioning system, the thermostat opens and closes all the time. You can’t keep the engine cool if there isn’t enough air coming into the engine fans. If a part of the cooling system breaks down, what will happen? In that case, the car will overheat, and the thermostat will stay open because the temperature of the coolant won’t fall below the setting set by the thermostat. It’s about 190 degrees Fahrenheit.

if the thermostat is taken out or if it is stuck open. They are also supposed to do this when they don’t work. A long time will pass before the engine is hot enough to work. If the outside temperature is very cold, it may not be able to get to operating temperature.

When the thermostat opened, there would be 1 minute of heat. When it closed, there would be 2–3 minutes of not having heat for that time.

Because the coolant is moving so quickly, some people think that an engine will overheat because there aren’t enough places for it to take in or exchange heat from the engine. This isn’t true. Physics and thermodynamics are not going to agree with this. There would also be no such thing.

How Much for Thermostat Replacement in Car Cost?

The good news for people who have a broken thermostat is that it costs a lot less to buy a new one. The exact cost will, of course, depend on what kind and model of car you have.

A skilled mechanic, on the other hand, might expect to charge the average car owner between $140 and $300 to fix their thermostat. The thermostat itself costs between $20 and $80, but in high-end cars or sports cars, it can cost more. Work is going to cost somewhere between $120 and $220. (Maybe more if you go to a dealership).

Keep in mind that most mechanics charge between $80 and $110 an hour to do their job for them. A mechanic should be able to replace the thermostat in about 1 to 2 hours, but it will depend on how well they do. To make things even worse, you end up paying more to hire someone to do something than to buy the thermostat itself.


Many people try to save money by changing the thermostat on their own. However, if you don’t have a lot of experience working on cars, or if your car’s thermostat is in a good place and you have a good repair manual, you should hire an expert to do the job.

After all, there’s always the chance that your car has another problem. You’ll need to hire an expert to figure out what’s wrong with the thermostat before you buy a new one.

In order to save money on labor, you couldn’t change the thermostat yourself. This may be a lot for a job like this, which is why you couldn’t do it yourself. But, on the other hand, it’s not very hard to fix. Find out if you have the right size thermostat replacement and where it is in your car’s engine before you try to do this job!

In general, there isn’t a set way that cars and trucks are put together, so if you don’t see it right away, you might need to look at an engine diagram or your owner’s manual to figure out what you need.

Thermostat Replacement essentials

The most important thing to do is to make sure that you have the right thermostat for your car. On the other hand, there are a lot of different thermostats out there. If you choose the wrong one, it won’t work. Fortunately, AutoZone lets you search by make, model, and year so that you get the right car.

Changing the thermostat in your car on your own isn’t very difficult, as you can see from this picture. When your car needs to be fixed, you’ll save a lot of time and money if you don’t have to go to the mechanic.


If you’re only paying about $20 for your car’s thermostat, it might be a good idea to try to fix it yourself. On the other hand, it will take you about 20 minutes to remove the old one and put in the new one after you figure out what you’re doing. That’s not bad.

Even though your thermostat is a simple piece of technology, it is very important to how your car works. In the long run, an engine with a bad thermostat could do a lot of damage.

Most of our attention is focused on a thermostat that can’t control the heat properly, which can cause engine damage because it can’t keep the engine cool enough. So, a cool engine is often overlooked, and it is sometimes thought that this is not a problem at all.

Is driving with a thermostat Stuck Closed or Open Okay?

Most auto mechanics will tell you that not having a thermostat in your car isn’t a good idea because it can get very hot. You can’t drive a car if your thermostat is stuck in the “closed” position, so your engine will overheat and you won’t be able to drive. Do you have to drive with an open or closed thermostat stuck in the middle?
