Caring for a car is more than just scheduling regular maintenance visits. It’s also essential to monitor the car’s fluid levels between services to ensure they are at proper levels and that no potential problems arise. Checking car fluids can be done quickly and easily if you know what to look for, how often it should be done, and why it needs to be done in the first place. In this article, we will discuss car fluid check: how to do it properly, and the importance of keeping your vehicle’s fluids in check.


What is a Car Fluid Check?

A car fluid check is a necessary vehicle maintenance procedure that monitors and ensures that the various fluids in a vehicle are at the right levels. Checking your car’s fluids regularly helps to ensure its proper functioning, increase fuel efficiency, and avoid potential problems. Depending on your car type, you may need to check oil, transmission fluid, coolant, brakes fluid, power steering fluid, and windshield washer fluid.


What are the Different Types of Car Fluids?

You should be aware of several different types of car fluids. These include:

Engine Oil

This is the most common fluid used in cars. It helps to lubricate, protect, and clean engine parts. It also helps to dissipate heat and protects the engine against wear and tear. With time, engine oil becomes contaminated and must be changed regularly.

Transmission Fluid

This fluid is used to help transfer power from the engine to the drivetrain. Therefore, it must be checked regularly as it lubricates and cools down the components in transmission systems. That way, you can ensure it is still working properly and prevent potential problems.


Coolant is a mixture of water and antifreeze solution that helps keep your engine cool, not overheat or suffer from corrosion over time. Regular checks on your coolant levels are essential for safe driving. That way, you can be sure your car will not suffer thermal damage.

Brake Fluid

This fluid type is essential for keeping your brakes properly by providing hydraulic pressure when the brake pedal is pressed. At the same time, it also lubricates the moving parts of your brake system and helps prevent corrosion. That way, the brake system will live longer and operate more smoothly.

Power Steering Fluid

This oil provides a cushion between moving parts, reducing friction as steering wheels are turned, making driving smoother and easier. It also lubricates the car’s power steering system, helping reduce wear and tear on its components. As a result, it is essential to check the car’s power steering fluid regularly and top it up if necessary.

Windshield Washer Fluid

This fluid is used to help clear dirt, debris, bugs, and other particles off windshields for improved visibility when driving. You can usually find this type of car fluid in the car’s reservoir, and it should be checked regularly to ensure it is full and not contaminated with dirt.

Differential Fluid

This fluid is used to help transfer power from the engine to the drivetrain. It helps to reduce friction, heat, and wear and tear on the transmission system components. Regular checks are necessary to ensure this fluid is at the right levels. At the same time, it also helps the car run more smoothly and efficiently.


Fuel is used to power your car’s engine. Different fuel types may be required, such as unleaded gasoline or diesel fuel, depending on your vehicle type. Checks should be done regularly to ensure that there are no leaks in the fuel lines and that enough fuel is always available.


The Importance of Checking Your Car Fluids

Regularly checking the different fluids in your car is essential for its overall health and performance. Here are some of the reasons why conducting car fluid checks is necessary:

Preventing Engine Damage

Engine oil and coolant are critical fluids that help to maintain the engine’s temperature and lubrication. However, low levels of these fluids can cause overheating, leading to engine damage and expensive repairs.

Ensuring Proper Brake Performance

Brake fluid plays a crucial role in stopping your car. However, low brake fluid levels can lead to brake failure, which can be dangerous for you and other drivers on the road.

Improving Fuel Efficiency

Transmission and power steering fluids are essential for your car’s smooth operation. However, when these fluids are low or dirty, it can cause your vehicle to work harder, reducing fuel efficiency and increasing wear and tear.

Keeping Your Windshield Clean

Windshield washer fluid is essential for maintaining a clear road view while driving. However, low levels of this fluid can make it difficult to see, especially in adverse weather conditions.

Preventing Costly Repairs

By regularly checking your car fluids, you can catch small problems before they become major issues. This can save you money in the long run by preventing costly repairs or replacements.


How To Conduct Car Fluid Checks?

Conducting car fluid checks is pretty straightforward as long as you know what and how to check them. With that said, below are six of the most common vehicle fluids and how to inspect them properly:

Engine Oil

  1. First, pull the dipstick out and wipe it clean with a towel or rag. Then, reinsert it and pull it back out. 
  2. The dipstick is marked with maximum and minimum levels; if the oil falls between these two marks, then you’re good to go! 
  3. If not, you may need to add more oil.

Coolant (Antifreeze)

  1. To check the coolant level, locate the coolant reservoir under the hood of your car and remove its cap. 
  2. Ensure that the fluid level is between the “full” and “low” marks on the side of the reservoir.
  3. If not, add more coolant as needed.

Power Steering Fluid

  1. To check power steering fluid levels, locate the reservoir under your hood and remove its cap.
  2. Again, make sure that the fluid level falls between “full” and “low” marks on the side of the reservoir
  3. If not, add more power steering fluid as needed.

Brake Fluid

  1. To check brake fluid levels, locate your brake master cylinder (usually near where your brake pedal meets your firewall).
  2. Remove its cap carefully—brake fluid can damage paint!
  3. Ensure there is enough brake fluid to reach just below the “max” line on its side.
  4. If not, top off with fresh brake fluid as needed.

Transmission Fluid

  1. If you drive an automatic transmission vehicle, you should check transmission fluid levels periodically – usually every 50,000 miles.
  2. Locate its dipstick under your hood and wipe it clean with a towel or rag. 
  3. Reinsert it back into its tube for an accurate reading of current levels. 
  4. If necessary, add more transmission fluid until it reaches just below its “full” mark on its dipstick tube.

Windshield Washer Fluid

  1. Check washer fluid levels by locating their reservoir under your hood (it will have a blue lid).
  2. Top off as needed with a new washer solution from any nearby auto parts store or gas station convenience store.
