Regular Car Maintenance – How Often Should You Check The Fluids In Your Car?  

The fluids in your vehicle are responsible for ensuring that all of its components operate efficiently and effectively. Fluids are used in the gearbox, power steering, wipers, and brakes. As a result of contamination, the amount and quality of each fluid gradually decline as it is circulated in its respective system, which results in a variety of issues with the vehicle. These fluids need to be flushed at different intervals, and it is essential to know when to bring the vehicle to the auto technician for each flush.

In order to get the most out of your vehicle, you should know “how often should you check the fluids in your car” and  routinely flush the following fluids:

Engine Oil

It is necessary to have engine oil in your car because it provides lubrication to the internal engines, which helps to prevent wear and friction. Additionally, it assists in the removal of varnish as well as sludge from the engine. Depending on how much you drive and the kind of oil you put in your vehicle, the recommended interval between oil changes for your vehicle is anywhere from 8,000 to 16,000 kilometers (km).

To determine the amount of engine oil in your vehicle, remove the dipstick and wipe it clean with a dry towel before placing it back. The next step is to re-immerse the stick in the oil and then remove it to get an accurate reading of the oil’s level. If it is low or if it seems to be unclean, it is time to take the vehicle to the service center.

Transmission Fluid

The working components inside your gearbox benefit from the lubrication that transmission fluid provides. This fluid not only acts as a coolant but also as a viscous fluid that enables power to be transferred from the engine to the gearbox. We advise replacing the gearbox fluid in your vehicle every 50,000 to 100,000 kilometers.

It is simple to check the transmission fluid at home if your vehicle is equipped with a second dipstick that is located under the hood. In the case of other automobiles, you may be required to go to the closest service center in order to get it inspected. It is strongly recommended that you check it each time you have your oil changed.

Not only the amount of the fluid should be observed, but also it’s quality. If it has a smoky odor or a brownish color instead of a red one, it is time to replace it.

Brake Fluid

This is also known as Hydraulic fluid. It is essential to move the components that make up the brake system in your vehicle.

Brake fluid should be checked at every oil change, or at the very least once a year. The reservoir for your car’s braking fluid is visible under the hood, and they have MIN/MAX markings to indicate the appropriate levels at which your vehicle should be maintained for optimal performance.

Power Steering Fluid

When you have your oil changed, most technicians will also check the fluid level in your power steering system. In most cases, it is recommended to check the power steering fluid while the engine is cold. Check your user manual for what works best for your automobile.

The reservoir is normally situated near the passenger side of the car.

If the level of power steering fluid is low, fill it up to the mark that says “MAX” or “FULL”.


You should check the amount of coolant at least twice a year. Under the hood of your vehicle, in the same location as the brake fluid tank, you’ll find the coolant tank. It will have MIN/MAX marks on it. In the event that you have no idea where to look for it, the owner’s handbook will be your best guide.

Windshield Wiper Fluid

When you check any of the important fluids listed above, be sure to give this one a cursory glance as well! If you open the hood of your vehicle, you will be able to locate the washer reservoir, which is often a white, see-through container with a sign of a windshield or water on the top. If your car has a rear wiper, there might be another reservoir for it; thus, you should also check the fluid level in that reservoir.

Take off the top so you can see how much water is left. In the event that there is insufficient fluid, add some to the reservoir (or reservoirs) until it is nearly at its maximum capacity.

The Bottom Line

To avoid breakdown, never let your vehicle’s maintenance go another day. If you are competent in doing your own car maintenance, it will not be difficult for you to monitor the levels of these fluids and replace them as necessary. On the other hand, if you do not know “how often should you check the fluids in your car” and if you do not feel confident doing these procedures on your own, it is a smart idea to seek the assistance of a reliable technician.
