Car fluids are one of the most important factors that ensure the proper running of a vehicle. From providing power to reducing friction for the smooth function of car parts, these fluids play various roles. Therefore, you should know the function of these fluids and how often to change them. Here are the 6 essential car fluids that keep your car going.
Essential Car Fluids to Check for Proper Vehicle Function
Following are the most important fluids in a vehicle:
1. Engine Oil
Engine oil is perhaps the most essential fluid of a car. Its function is to alleviate friction inside the car engine and ensure efficient operation. Car engine oil also cushions the engine parts and protects them from heat damage. Furthermore, oil has cleaning properties that keep the dirt from clogging the engine’s opening.
The engine oil of a car should be changed at least after 5,000 to 8,000 kilometeres. However, this is a general estimate and depends on the type of oil used as some even last for a good 15,000 kilometres.
How to check car engine oil
First, check your car manual to ensure you have the right type of oil. Then park your vehicle on a flat service and wait for the engine to cool off. This will help the oil settle down and give you a more accurate estimate of your car’s oil level.
Use a dipstick to get a reading on your car engine oil. Your car is likely to have a dipstick already. Take it out and clean the excess oil with a cloth. Insert the dipstick back and then take it out. Check the oil level against the minimum and maximum marking. This indicates if you need to add more oil.
Also, check the quality of the oil. If it has changed colour and looks milky or contains deposits, you need to replace the car oil for proper car functioning.
2. Antifreeze/Coolant
Cars convert chemical energy to mechanical energy for their functioning. However, a major amount of energy is lost as heat. This can overheat your car and damage its parts. This is where a coolant comes into the picture. It absorbs the extra heat and removes it via the exhaust. Moreover, the same fluid prevents damage to the car due to freezing in the winter.
You must flush the coolant every 50,000 to 80,000 kilometres.
How to check car coolant
To check your car coolant, make sure the engine has cooled down. Otherwise, the hot coolant might splash on your skin and cause severe burns as soon as you open the tank’s lid. Check the level of the coolant against the marks on the coolant tank. In case, it is below the minimum level, refill it. Make sure you use the right right coolant colour grade and type for your vehicle.
3. Power Steering Fluid
Power steering fluid transmits power to the car’s steering wheel. It ensures the wheel steers effortlessly. If you feel the signs of failing steering wheel has become harder, it is time to check the power steering fluid in your car.
It is recommended to perform a power steering flush after around 50,000 kilometres. Please remember that steering fluids are specifically designed to be used in steering. It is a common myth that brake fluids can be used as steering fluid that can cause severe damage to the vehicle.
How to check power steering fluid
Check your car’s manual to locate the fluid reservoir as well as check the fluid type required. Power steering fluid reservoirs have markings along with hot and cold indications. Use the cold readings to measure if the car wasn’t driven in the last 8 hours. Otherwise, check the hot level marking. If there is a need to refill, use a funnel to pour the fluid.
4. Brake Fluid
Cars require brake fluids to stop. No or low level of car brake fluid will make it difficult for your car to stop when the brakes are applied. Since a vehicle should stop instantly when the brakes are applied to avoid accidents, any delay can be dangerous. If this happens, you should check the brake fluid in your car immediately.
You should replace the brake fluid every 50,000 kilometres or in case of any malfunction. Brake fluid is hygroscopic and must be changed after 2 years to avoid rusting of the brake lines.
How to check the brake fluid
Locate the brake fluid reservoir in your car engine bay. Check the level and colour of the fluid. Dark or cloudy fluid needs replacement as brake fluid is supposed to be transparent. The fluid level should be between minimum and maximum. Otherwise, fill or remove as needed. A lower level of brake fluid could be an indication of faulty brake pads.

5. Transmission Fluid
The purpose of transmission fluid is to reduce the friction heat and keep the transmission cool. It lubricates the transmission parts and ensures efficient transmission functioning.
Transmission fluid must be changed after 80,000 kilometres or at least every 3 years
How to change transmission fluid
You should not change the transmission fluid yourself. It is not a DIY task, especially for manual cars. However, even with automatic cars, you should visit a car mechanic to get the transmission fluid changed properly without posing any hazard.
6. Differential Fluid
Differential fluid performs the important function of distributing transmission power to each wheel. Since wheels move at different times and speeds, the fluid accommodates the difference between the wheels and how they move.
Differential fluids should be changed at least every 50,000 to 80,000 kilometres of usage.
How to check the differential fluid in your car
Check the vehicle manual to figure out the type of differential fluid that will be suitable for your car. Locate the differential plug and remove it. If the fluid trickles down, there is no need to refill it. However, if it doesn’t spill, you need to add the fluid. Then put the plug back.
For light trucks, changing the differential fluid is not that difficult, but in the case of cars, it is better to opt for an automotive professional to get it changed.
7. Windshield Washer Fluid
Lastly, there is the windshield washer fluid which is also an important one for your car. While it doesn’t affect the engine performance, it is essential for road safety. It is a simple mixture that makes sure your car’s wiper are doing their job well. Not only does it clean the windshield without hassle, but also prevents corrosion of wiper blades and their internal components. Make sure the reservoir has an adequate level of fluid, especially when there is a bad weather forecast.
Windshield washer fluid should be refilled at every service interval, at a change of season and whenever it runs out.
How to check the windshield washer fluid in your car
Locate the washer fluid reservoir by opening the car hood. It is usually translucent container with either windshield or water symbol on its cap. In case your car has a rear wiper, there might be a second reservoir. Now uncap the reservoir and check the fluid levels. If it is full, close it but if the level is low, fill it up to the brim. replace the cap and make sure it is properly shut before closing the hood.
Note: All the limits given here are general estimates. They might vary a little based on the type and company of the fluid chosen as well as the overall performance of your car.
This is all about important car fluids, how and when to check and change them. If your car needs a fuel replacement often, you might like to consider another option. Check out these used cars for sale and buy a vehicle of your choice at economical prices.
