Fluids play an important role in keeping your car in good condition. You should know when and how to check and replace them by considering the following tips: 

Engine Oil

Engine oil is the most essential fluids in your car. It lubricates the engine and prevents it from overheating. Engine oil is responsible for keeping the car’s engine in good condition. You should check the engine oil levels once a month by using a dipstick. If the engine oil levels are low, you should replenish it. It is a good practice to change the engine oil every 3000-5000 miles. 

Brake Fluid

Brake fluid is responsible for ensuring proper maintenance of the braking system of your car. The braking system is hydraulic, so it depends on brake fluid to create pressure which is used for stopping the car. It is important to replace your brake fluid for your safety while driving. You should constantly keep monitoring your car’s brake fluid level and never allow it to get too low. Brake fluid collects moisture over time which will reduce its performance and hence it needs to be replaced. It should be replaced at least every 1-2 years. 

Transmission Fluid 

Transmission fluid is responsible for keeping your gears running smoothly. Just like the brake fluid, the transmission fluid works in a closed system which requires regular monitoring for spotting any leakages. You should check the user manual of your car to understand the frequency of the replacement of transmission fluid. Ideally, you should get the transmission fluids checked every 30,000 miles. You should replace the transmission fluid after running 50,000 miles or even before that if it gets brown or smells burnt. 


Coolant is a mixture of water and antifreeze which is stored in the radiator. The primary purpose of coolant is to keep the car’s engine cool. You should regularly check the coolant level by using a dipstick inside the radiator. If the coolant level is low, you should replenish it. Coolant should be replaced every 2-3 years. It should be checked once before the onset of summer and winter.

Power Steering Fluid 

Power steering fluid allows you to effortlessly control your car’s steering. It is an important fluid that should be checked regularly. It enables you to get better control of the car while driving. While driving if you hear unfamiliar and weird noises from the steering wheel, then it can be indicative of low power steering fluid. The power steering fluid needs to be checked at least once a month. This fluid will rarely be required to be completely flushed out and replaced. A top-up of power transmission fluid is enough to keep your steering in good condition.
