If you're wondering, “how many fluids are in a car?” Your vehicle typically has six important fluids, including:
1- The engine oil
2- The coolant
3- The power steering fluid
4- The brake fluid
5- The transmission fluid
6- The windshield fluid
Did you know that your vehicle has a long list of fluids that play critical roles? Although your car needs a perfectly working engine and a great transmission, if it doesn't have these fluids, it cannot run at all, and without the fluids, your vehicle might fail.

Learning about “how many fluids are in a car?” And highlighting the role of each fluid helps you better understand how important it is to keep these fluids at the optimum level. This article walks you through the top six car fluids along with their jobs, so you can use the article as a quick reference rather than searching through the entire vehicles owner’s manual.
How many fluids are in a car, and what are their roles?
In general, every vehicle contains the following six very critical fluids:
1- The engine's oil
The engine's oil is almost the most critical type of fluid that you need to maintain at the optimum level. Since the engine generates a lot of excess heat, it can overheat quickly result in engine damages.
Also, the engine contains many internal moving components that interact with each other and generate a lot of friction. This friction also adds up to the excess heat and speeds engine overheating. Luckily, with the engine oil, the engine receives the right level of lubrication that prevents friction and brings the engine's temperature to the optimum level.
It is important to note that the engine oil breaks down over time, which means that you cannot use it forever. Thus, you need to follow a schedule usually specified in the new vehicles owner’s manual about when to change the engine oil.
If you fail to change the engine oil right time, you sacrificed the entire engine. This is because the old oil contains many contaminants that prevent the oil from lubricating the engines properly. Thus, engine overheating is one of the very common consequences of ignoring or skipping the oil change.
2- The coolant
The coolant is another very common type of fluid you'll see in any vehicle. The coolant is a combination of water and antifreeze. This mixture works together to cool down the engine, and it's part of the cooling system.
The coolant usually runs around the engine whenever the engine temperature passes a certain threshold. The coolant must be maintained with the same amount specified in your vehicle's owner’s manual. Otherwise, the engine can overheat and get damaged in no time.
Therefore, it is also a good idea to make a habit of monitoring the coolant level and keep an eye for any signs of coolant leak to prevent major failures in your vehicle.
Like the engine's oil, the coolant is another type of fluid that needs to be flushed at a certain point. Since the coolant runs around the engine continuously, it collects many debris and contaminants, which need to be cleaned up and refreshed. The process is referred to as the radiator flush. By performing the radiator flush, you get the benefits of the new coolant. As a result, your engine temperature will stay within the good range, and it won't have to suffer engine overheating issues.
3- The power steering fluid
Unlike the engine oil and the coolant, the power steering fluid plays a different role. It is responsible for linking the steering wheel and the wheels hydraulically. The steering system relies on this fluid to provide the right amount of power to move the wheels in response to any driver's input from moving the steering.
It's critical to keep the steering fluid at the optimum level because otherwise when you move the steering wheel, you won't see the right response from the wheels, and therefore, it can put your life and safety at risk.
You must keep an eye on the steering wheel fluids and learn about the common steering wheel fluid color so you can notice it immediately if there are any signs of a leak underneath the vehicle.
4- The brake fluid
The brake fluid is even more critical than the steering fluid, and the other types of fluids mentioned earlier here. This is because this fluid goes directly towards your safety. Never off in other words, if your braking system does not have the right level and pressure of the braking fluid, you won't be able to stop the vehicle at the right time, and this can be extremely dangerous if you're driving on the highway speed.
The brake fluid converts the force you push on the brake pedal into pressure that stops the vehicle when needed. Unfortunately, the brake fluid is extremely sensitive to pressure, and without the right level of pressure, you will likely fail to stop the vehicle in critical situations.
That's why we always recommend that you have proper inspection and maintenance of the braking system and inspect for any signs of leaks as early as possible. Typically, brake system leaks do not happen suddenly. However, the braking system will show you some symptoms indicating some early signs of minor cracks inside the brake fluid line so you can detect it as early as possible and resolve the issue without putting your life at risk.
5- The transmission fluid
The transmission fluid has a variety of jobs. For example, depending on the type of transmission system, the fluid might get involved in the hydraulic power and switching gears.
In general, the transmission fluid provides the right level of lubrication to the internal moving components inside the transmission and prevents overheating due to friction.
It also has some additives that prevent rust and protects the internal components of your transition. Thus, with the right type and status of transmission fluid, you extend the transition's lifetime and prevent its premature failure.
6- Windshield fluid
Finally, as the name suggests, the windshield fluid is the type of fluid you use to wash the windshield spirit in general; the windshield fluid is not as essential or as critical as the previously mentioned fluids. But it can be extremely critical if you're driving in areas with a lot of rain, and you will most likely utilize the windshields.
Having the right amount of windshield fluid also is not as important as the previously mentioned fluids. However, you want to have enough fluids to wash the windshield whenever needed, and you can't use the wipers properly if there is no enough fluid. Thus, if you know that you're driving on a day where there is a lot of rain, or you're expecting to use the wipers, consider inspecting the reservoir and checking if you have the right amount.
Keep in mind that you might even want to switch to a different type of windshield fluid suitable for extremely cold weather conditions or extremely hot areas where the water is expected to evaporate. But, again, there are plenty of available shield types in the market that you can research and learn about.
How much does it cost to replace all fluids in a car?
In general, changing all fluids in your vehicle might cost you somewhere between $80 and $250. Obviously, the range differs significantly depending on your vehicle's type and status.
Keep in mind that it is not very common to change all the fluids at once because each type of fluid has its own lifetime, requiring a certain frequency of changing.
Therefore, it is better to look at each fluid replacement or change costs if you want to learn about fluid changes expenses.
For example, changing your engine oil should cost you somewhere between $35 and $75. However, the price can also be different depending on where you get the job done. For example, some people might prefer to change their oil, which means that they don't have to worry about any labor costs, while others prefer to have it done at a dealership where labor cost is extremely high.
On the other hand, radiator flush costs should cost somewhere between $100 and $150. Remember that the price is also a function of where you get the job done and what type of coolant you decided to go with.
If you're planning to change the steering system fluid, expect to pay somewhere between $90 and $125. The price is primarily a labor cost, and the steering fluid itself should not cost you more than $10, and that's why many people prefer to flush the steering system by themselves.
However, it's important to note that many DIYs do not work the first time. Therefore, if your first time trying this flush, you must confirm that you have the right level of mechanical skill sets to prevent introducing damages that could cause issues that are costing you thousands of dollars.
How often should I change fluids in a car?
Although every fluid requires a certain frequency for change, you generally recommended changing all fluids at least once every three years or every 30,000 miles.
Keep in mind that most fluid changes go by miles thresholds, which means that the more you drive your vehicle, the more you need to change the fluids. However, this does not mean that you don't need to change the fluids if your vehicle sits idle or if you don't use it. That's not the case because there is another threshold you need to watch for, which is the number of years the fluid has been sitting in the vehicle.
To get accurate estimates about when to change the fluids in your vehicle, we always recommend going through your vehicle's owner’s manual. They all manual should have a list of scheduled maintenance that you need to follow. It will tell you exactly when to change the engine oil and what type of oil to choose. It will also highlight the steering fluid you need to put in the vehicle, so you don't introduce damages.
If you think it's not as simple to go through the manual, you can always refer to a trusted mechanic who can walk you through what needs to be changed and when depending on your vehicle's specific make, model, and year.
