The 5 car fluids that you should check

car fluids

Apart from the official reviews in the workshop, do not forget to check thecar fluids like oil level, coolant or brake fluid. Better to prevent than to repair.

Throughout the year, cold or hot, every so often you should check the levels of the car’s liquids. It depends on them that the engine works well and you do not have to visit the workshop ahead of time and with consequences, generally, more serious than desired.

OILcar fluids

The lubricant is one of the fluids of the car whose revision is more internalized. Who else who least knows the catastrophic consequences of not changing the oil or bring the level below the recommended (or above).

Therefore, in addition to replacing it when indicated by the manufacturer (between 5,000 and 30,000 kilometers, depending on the model), its level should be checked frequently. At least once a month and always before a long trip. And if the car is old, better every two weeks. It is one of the importantcar fluids.

How to check the level?

  1. Place the car in a flat, horizontal position and allow the engine to cool down since the level is always higher when hot.
  2. Remove the dipstick and clean it.
  3. Re-insert the rod to the bottom and remove it. At the end of the rod there are two notches that indicate the minimum and maximum level: check where the oil mark is.

If the level is low …

The most appropriate is to go directly to the workshop and ask for an oil change: cars, especially older vehicles, sometimes consume more lubricant than expected and it is advisable to make the change every few kilometers.

If the level is minimal, you can also pass the trance (although sooner or later you will have to go to the workshop) adding some lubricant. It is convenient to know which oil grade they used last time to add one of the same kind.

If the level is high …

Direct to the workshop. There they will remove the excess and verify that this excess has not produced any damage due to excessive pressure.


The coolant fulfills a fundamental mission among the fluids of the car: it circulates through the internal circuit of the engine and absorbs part of the heat generated by combustion, thus avoiding overheating that could be fatal. An excess of temperature could melt the pistons and even trigger a dangerous internal explosion.

The coolant is usually composed of distilled water and concentrated antifreeze, which also ensures that the liquid does not freeze and spoil the circuit in winter. In summary, the refrigerant must have a very high boiling temperature and a low freezing temperature, apart from anti-corrosion and anti-fouling properties.It is one of the importantcar fluids.

It is advisable to check it every 20,000 or 30,000 kilometers and replace it (before it loses properties) every 40,000 kilometers or every two years.

How to check the level?

  1. As in the previous case, the car should be placed on the level and horizontal ground and with the engine stopped and cold (otherwise, the liquid could be very hot and eject steam).
  2. Locate the bottle: it is large, square and translucent in general. Two marks indicate the minimum and maximum levels.

If the level is low …

As simple as taking a funnel and filling. You must use the one recommended by the manufacturer and never mix two different ones. When you do not find the one you need or are not sure which one is, fill only with distilled water. If the level is very low and it is winter, lowering the antifreeze concentration by pouring a lot of distilled water can be risky, so a complete replacement in the workshop may be appropriate.

If the level is high …

Workshop. Because emptying the tank means looking for (and releasing) the drain plug, located in the lower part of the radiator. And this operation can be dirty and cumbersome.


One of the less important car liquids at first sight, but that can also give you a dislike. Apart from the fact that a dirty windshield is dangerous (especially when facing the sun), you may have ITV problems. They do not always put up with the empty tank, but sometimes they do, so it’s best to take it at least half full.It is one of the importantcar fluids.

How to check the level?

Very easy: if you operate the lever and the wipers move, but no water comes out, it’s over. It also serves a simple observation of the deposit located under the hood, which is also translucent to verify how full it is.

If the level is low …

When you have reached the previous point, touch fill. It is simple.

  1. Let the engine cool down so it does not burn when you touch any part that is still hot.
  2. Locate the tank: it will be under the hood, usually on one of the sides and near the windshield (the plug has the windshield wiper pattern engraved).
  3. To fill, you usually need a funnel (or very good pulse) and a specific liquid, especially to prevent it from freezing at very low temperatures.

If the level is high ...

This can only happen if you happen to fill in, so just pay attention. Continue reading-Top 10 Car Maintenance Tips For A Happy Car

BRAKE FLUIDcar fluids

It goes without saying that the brake is another hydraulics circuit of the car essential for safety, so it should be reviewed periodically (a couple of times a year, for example). The change of liquid will be every two years, approximately, since the humidity accelerates its deterioration and the boiling point also reduces with time.It is one of the importantcar fluids.

How to check the level?

  1. With the engine cold, locate the tank. Take a black cap with yellow letters.
  2. Check that the level is between the maximum and minimum indicators.

If the level is low …

There is no choice but to go to the workshop because the most frequent is that the brake pads are worn (which makes the level appear lower).

If the level is high …

It will be strange that this happens, but we will also have to ask the expert.


If your car has hydraulic or electrohydraulic power steering, you should check (at least once a year) the steering fluid.It is one of the importantcar fluids.

How to check the level?

  1. With the engine hot, locate the tank. Take a steering wheel engraved on the cap.
  2. The same cap usually incorporates the dipstick. Clean it, like you did with the oil.
  3. Re-insert the rod and, when removing it, check that the level is between the maximum and the minimum

If the level is low …

You can fill it yourself, always with the liquid recommended by the manufacturer.

If the level is high …

In the very rare case of this happening, consult the workshop.
