Car maintenance fluids - when do we have to check and replace them?
Consumable fluids are an integral part of the car, crucial to its proper functioning. However, they raise a number of questions: What are they? Why are they so important? What types of operating fluids are there in a car?
Operating fluids are special substances that are essential for the smooth functioning of various car components. Their presence has a direct impact on the durability of individual components, safety when travelling and the overall performance of the vehicle. The most important types of operating fluids include brake fluid, coolant, windscreen washer fluid, transmission fluid, power steering fluid and engine oil.
Brake fluid
The role of brake fluid
Brake fluid is essential for a car's braking system. It transmits the force from the brake pedal to the brake callipers, enabling the car to stop. It also dissipates heat from the brake system components.
When to check and replace brake fluid?
Brake fluid should be checked at least once a year. It should be replaced every 2 years or as recommended by the car manufacturer.
How to check and replace brake fluid?
The brake fluid level can be checked by opening the fluid reservoir and observing the level indicator. If the level is low, the fluid should be topped up. Brake fluid replacement should be carried out by a professional due to the complicated process and the possibility of air bubbles in the system.
Coolant
Coolant function
Coolant, also known as antifreeze, ensures that the engine is properly cooled, protecting it from overheating. It also protects the cooling system from corrosion and freezing at low temperatures.
When to check and replace coolant?
Coolant should be checked at least once a year and replaced every 2-3 years, unless otherwise recommended by the manufacturer.
How do I check and replace the coolant?
The coolant level can be checked through the transparent expansion tank. If the level is low, it should be topped up. Changing the coolant should be carried out by a mechanic, as it requires bleeding the cooling system.
Windscreen washer fluid
Why is windscreen washer fluid important?
Windscreen washer fluid is essential to keep the windscreen clean for clear visibility when driving. It may contain chemicals to prevent freezing at low temperatures.
When to check and replace windscreen washer fluid?
Windscreen washer fluid should be checked regularly and refilling depends on the frequency of use. It is best to keep the tank full to avoid running out of fluid while driving.
How to check and replace windscreen washer fluid?
The washer fluid reservoir usually has a transparent cap through which the fluid level can be checked. If the level is low, simply top it up.
Transmission fluid
What is transmission fluid and what is it used for?
Transmission fluid is used in a car's gearbox. It provides lubrication, cooling and corrosion protection for the transmission components. It also acts as a power transmission medium from the engine to the wheels.
When to check and replace transmission fluid?
Recommendations for checking and replacing transmission fluid vary depending on the car manufacturer and transmission type. Some recommend checking every 30,000 - 60,000 km, others say the fluid is for life. It is best to consult a mechanic or check your car's owner's manual.
How to check and replace transmission fluid?
The transmission fluid can be checked with a dipstick, just like the engine oil. If the level is low or if the fluid is dark in colour or has an unpleasant smell, it should be replaced. Changing the transmission fluid should be carried out by a professional, due to the complexity of the process.
Power steering fluid
The role of power steering fluid
Power steering fluid enables the steering wheel to turn more easily. Reduces friction and wear in the power steering system, ensuring smooth and efficient operation of the system.
It is recommended to check the power steering fluid at least once a year. The fluid should be changed every 2-4 years, but recommendations may vary depending on the car manufacturer.
How to check and replace power steering fluid?
The power steering fluid level can be checked with a dipstick or through a transparent reservoir, depending on the car model. If the level is low, it should be topped up. Fluid replacement should be carried out by a professional, due to the risk of introducing air into the system.
Engine oil
Why is engine oil so important?
Engine oil performs many functions, including lubrication, cooling, cleaning and protecting the engine from corrosion. Without it, the engine would quickly deteriorate.
When to check and change engine oil?
Engine oil should be checked at least once a month and changed every 5,000 - 10,000 km or every 6-12 months, depending on the car manufacturer's recommendations.
How to check and change engine oil?
The engine oil level can be checked with a dipstick. If the level is low, it should be topped up. An oil change should also include changing the oil filter and should be carried out by a professional to ensure that used oil is properly disposed of and disposed of.
The most common errors relating to operating fluids
Among the mistakes related to automotive operating fluids, we can distinguish the three most common ones:
- Ignoring the need for regular checks - Regularly checking the level and condition of operating fluids is fundamental to keeping your car in good working order. Skipping this step can lead to premature wear of components and, in extreme cases, even serious breakdown.
- Using the wrong fluid - Each operating fluid has a specific purpose and composition that is tailored to the specific system in the car. Using the wrong fluids, such as replacing coolant with water, can lead to component damage and reduced car performance.
- Overfilling the fluid reservoir - While it may seem that more fluid is better, overfilling the fluid reservoir can lead to problems. For example, if the engine oil level is too high, this can lead to excessive foaming, which in turn can lead to oil pressure that is too low.
All these mistakes can lead to serious problems, such as damage to the car or dangerous situations on the road. This is why it is so important to know and understand the importance of proper maintenance of the operating fluids in our vehicles.
Tips for maintaining operating fluids
Keeping your car's maintenance fluids in good condition requires some knowledge and regular care. Here are some tips to help you maintain your operating fluids properly:
- Regular checks: Maintenance fluids should be checked regularly for level and quality. Some, such as engine oil and coolant, can be easily checked by yourself. Others, such as brake fluid, may require more specialised knowledge or tools.
- Use recommended fluids: each car has its own specifications for the type and brand of operating fluids that should be used. This information can be found in the car's owner's manual. Using the wrong fluids can lead to component damage and reduced vehicle performance.
- Avoid overfilling the tanks: Overfilling the tanks with operating fluids can lead to problems. For example, too much engine oil can cause excessive foaming, which in turn can lead to too little oil pressure. Always aim to keep fluids at the recommended level.
- Regular replacements: Some operating fluids, such as engine oil or brake fluid, require regular replacements at certain intervals or after a certain number of kilometres.
- Paying attention to warnings: Many cars are equipped with warning systems that indicate low levels or problems with operating fluids. Always pay attention to these signals and act in accordance with the instructions.
Summary
The operating fluids in a car play key roles in its proper operation. Regularly checking and replacing these fluids is essential for keeping your car in good condition, as well as for road safety. Remember to always consult a professional or refer to your car's owner's manual if in doubt.
