What Fluids Does My Car Need?

Regularly checking your car’s fluids should be an essential item on your to-do list. Fluids help run practically every part of your vehicle, and you want to catch any issues early before they start causing problems.

There are six car fluids to look for in your vehicle, and you should regularly check on their levels. Keep reading to learn more about the fluids your car needs.

Engine Oil

While all fluids serve their purpose, engine oil is one of the most important. It keeps your engine lubricated and ensures it can run properly.

Engine oil needs to be changed every 3,000 miles or 5,000 miles if you are using synthetic oil. You can schedule an oil change with your local auto mechanic. They can help you use the right oil for your vehicle’s engine and also check all the other fluids in your car.


Coolant, also known as antifreeze, is the fluid responsible for keeping your engine from overheating during the summer. Since your engine produces a lot of energy, it also creates heat. The coolant absorbs the heat and then funnels it out of the car’s exhaust pipe. This process ensures your engine doesn’t overheat and break down. It’s also useful in the winter because it stops the engine from freezing.

Power Steering Fluid

Power steering fluid makes it easier to move your steering wheel. Without it, your steering wheel becomes stiff and harder to move. If you notice your steering wheel is more difficult to move than normal, it could indicate that your power steering fluid is low or has a leak.

Brake Fluid

Brake fluid is another crucial aspect of keeping your vehicle running smoothly. Braking is supposed to happen immediately, but if there isn’t enough brake fluid, then your vehicle may take longer to stop. Or worse, you may be unable to stop your vehicle at all. This is a hazard, so you should make sure your brake fluid is at an optimal level.

Brake fluid should be flushed annually or every other year, depending on your vehicle. It’s best to schedule a brake inspection to check the fluid and other parts of your braking system.

Transmission Fluid

Transmission fluid is another crucial part of running an engine properly. It helps lubricate the transmission gears and clutch packs. There are several types of transmission fluid, and what your vehicle needs depends on your car type.

If you have an automatic transmission, it’s fairly easy to change. However, manual transmission requires a mechanic to look at it. It’s always best to get a professional to help if you are unsure about your vehicle.

Windshield Washer Fluid

While it’s not a necessity to run your vehicle, windshield washer fluid is critical to ensuring you can see while driving. Windshield washer fluid helps you clean your front windshield while you’re driving. Many people consider this fluid the easiest to replace. Open the hood, find the cap with a windshield wiper fluid symbol, and pour in windshield washer fluid until full.
