Air Filter Maintenance

An engine needs two things to run: fuel and air. The air absorbed by the motor must first pass through the air filter. The function of the filter is to retain the impurities without affecting the flow of air entering the engine for combustion.

When driving with a filter in saturated state, engine performance will be affected, which could lead to malfunctions. It would also imply an increase in the emission of polluting gases into the atmosphere. The air filter is crucial for optimum engine performance that can be changed easily and for a good price (between 10 and 40 euros) piece.

replacing air filters due time prevents further damage that would require a major expense for repairs

What is the purpose of the air filter?

The air filter is the first part of the engine intake system. It retains the dust particles in suspension so that they do not enter the combustion chamber.
If the filter becomes saturated and is not replaced, the particles could cause it to penetrate and cause scratches on the pistons and cylinder walls, which would result in premature deterioration of the engine. Therefore, replacing air filter due time prevents further damage that would require a major expense for repairs.

A saturated filter will also block air passage, reducing the inlet flow to the engine. If less air were to enter the combustion chamber, that difference would be covered by a higher fuel input. That is, the vehicle would consume more fuel than necessary, while the power of the engine would be reduced.

In addition, the decompensation of the balance between fuel and air would cause exhaust gas emissions to be polluting, since a disproportionate mixture does not burn properly.

When should I change the air filter?

The major brands of air filters usually recommend a range of kilometers for replacement. However, the truth is that these values ​​can vary significantly depending on the environment in which the vehicle is driven and the time of year. For example, dry areas and dirt roads would dirty the filter first. The same thing happens with the pollen of the trees in spring and summer.

Typically, in each periodic review it is carried out an exchange air filter . But if you want to have a first-hand control of the filter of your car, you will be interested to know that two of the most notorious indications that the filter is saturated is the decrease in power when accelerating and the emission of opaque and dark gases through the tube Of escape.

Another indicator that you must change the filter is the malfunction of the electronic sensors due to the obstruction of the air passage. These include the flow meter and the pressure sensor of the intake manifold.

You can also remove the filter to check its level of dirt. The original color of the filters is usually a light yellow or white. Try shaking it a bit to remove dust from its surface and check the dirtiness of the paper fiber, but do not try to clean it because you could break it. If you decide to change the filter, we recommend you do it through a professional workshop.

Clean the air filter: an option to discard

Cleaning the filter with a blowtorch is a widespread practice among mechanics. However, experts recommend avoiding it, since cleaning will only allow loose particles of dust to be removed, but not those retained in the paper fiber. It is impossible to remove the retained particles without damaging the filter. As the improvement offered by surface cleaning is insignificant, it is necessary to change the air filter when it is dirty and thus contribute to the performance of the engine and prevent further complications.

Why should you change the brake pad of your car?

Brake pad are essential for your safety on the road. Its function is to generate the necessary friction to slow the movement of the brake disc, which is coupled to the wheel and stops it. For this reason, brake pad in good condition can make the difference between a braking in time and an accident.

Most cars have two brake pad per disc, which means that there is a set of four brake pad on the front axle and another set on the rear axle. These brake pad consist of a metal bracket and a lining, which is worn away with each braking, which means that its life depends largely on the number of times you brake and the intensity. Use engine braking is a strategy to protect them , but sooner or later you will have to replace the brake pad front and rear car brake.

the best way to check if need to change the rear brake pads or front is to measure its thickness

When to change the brake pads?

Over time and use, the contact surface of the brake pads wear out, which means that the braking efficiency is reduced and the car will travel more meters before stopping. Fortunately, most cars now have a wear indicator on the dashboard, which tells you when the pads are about to reach the end of their life.

However, there are other signs that the time has come to change the brake pads, such as when you notice that you have to tread increasingly brake pedal to achieve the same braking effectiveness. In fact, the brake fluid is one of the first indicators that the pills have little time to live. When the pads are worn out, the piston of the brake caliper has to move further to compensate for the loss of material.

What is the minimum thickness of the brake pads?

As a rule, it is recommended to check the condition of the brake pads every 25,000 kilometers, although it is important to note that their wear will depend largely on your driving style. You should also consider that the front pads wear out more than the rear ones as they practically work twice as hard.

However, the best way to check if need to change the rear brake pads or front is to measure its thickness. In some cases, you only have to remove the wheel, but in other models you will have to dismantle the brake pads themselves.

Some brake pads have their own indicator of minimum thickness, which allows to evaluate their wear simply by taking a look. In other cases you will have to measure it , considering that when the material thickness is less than 2 mm at some point, there will be time to change the brake pads.

How much does it cost to change the brake pads?

Changing the rear or front brake pads is not expensive as it is an intervention that usually does not exceed 30 minutes, although the price varies depending on the vehicle model and the type of pill. However, you must consider that when you decide to change the brake pad, you have to replace all the same axis. You should change the rear and front brake pad of your vehicle at once. In addition, also make sure to thoroughly clean all parts, lubricate the pins and properly adjust the clamp.

Ask for oil: How to avoid the risks involved in using a poor quality engine oil

The main function of engine oil is to minimize contact between the metal parts, minimizing friction and, consequently, wear. The engine oil is responsible for creating a very thin film between the metal elements, to facilitate their slip. It also acts as a refrigerant where the coolant does not reach, to prevent the heat from deforming the moving parts.

When the engine is well lubricated, it maintains its power and makes maximum use of the fuel, but when it lacks engine oil, or is of poor quality, it lost its properties, the engine suffers the consequences and can even break. Therefore, when changing the engine oil , it is important to ensure the professionalism of the workshop that will take care of it.

One of the most common problems is that the oil does not withstand the high temperatures reached by the engine

What can happen if you use an inadequate or poor quality engine oil?

Always remember, please accept. The choice of engine oil should not be made lightly because if you use a poor quality, without sufficient guarantees, or you resort to an oil that is not the most suitable for the car, the engine will end up paying the consequences .

One of the most common problems is that the engine oil does not withstand the high temperatures reached by the engine. It is important to clarify that all lubricants oxidize when they come in contact with air, but if the engine oil is of quality it will be able to better support this process as it contains antioxidant additives. On the contrary, when it is not of good quality, it carbonizes more easily and drags with it those particles, which increase the friction and damage the moving parts of the engine.

On the other hand, it should be noted that engine oil contains a number of additives that should serve to improve and preserve their properties. These added substances should encourage cold starting of the engine and prevent the formation of coals, sludge and foam. However, the resulting mixture must be homogeneous and balanced since, otherwise, there is a risk that it will over-thick and will not flow or that it will be too liquid and will not form the protective film. In fact, some additives can even cause excessive engine wear.

For all these reasons, it is important that you make sure that the workshop where you are going to change the oil is authorized by the main brands as they meet the requirements that are demanded by the largest manufacturers of vehicles and subject the engine oil they produce to a series of Tests performed on standard motors in extreme conditions of use.

Where to buy Buy guaranteed quality motor oil?

At various oil seller, where they only work with the best brands in the market, in order to guarantee the highest quality at the best price. In fact, they might have different offers and discounts that will save you money if you ask for motor oil as this service also includes changing the oil filter and reviewing 20 basic safety points of your vehicle. In addition, you can count on the experience of their mechanics, who can recommend the type of oil most suitable for your car, taking into account the type of engine, its age and the use you give.

What is a vacuum pump and when can it fail?

These vacuum pumps are also used in electric cars.The main function of the vacuum pump of a diesel engine is to provide sufficient suction in order to provide power to the vehicle power brakes.

In order to learn more about the operation of this element of the car, Loctite published an article on his blog in which notes that the vacuum pump also provides energy for air conditioning, ventilation systems, opening and closing Solenoid valves and central locking.

Harder brakes or lack of suction are symptoms of failure
This mechanism is similar to an air compressor p ero with the valves changed to absorb rather than to expel air. Thus, in a normal car the vacuum pressure level is 16 “to 18” Hg (inches of mercury), that is, about 54,000 Pa or N / m2.

Furthermore, it is common these pumps are also used in electric cars, as indicated by the post, and using servo. The difference of the brake system in an electric car lies in the mechanism with which the vacuum is made to the brake booster, since in the electric vehicles is carried out with a vacuum pump.

In the case of long braking the post states that you can spend the pressure induced in the circuit until the pump pressure again have spend a few seconds.

To avoid this , experts point out that Loctite can install a vacuum tank between the brake booster and an extra pump to maintain pressure. The larger the reservoir, the greater the braking capacity. Since this pump operates when the engine is turned on , it is possible, as measured by technicians Loctite, which at some point may fail.

For this reason, the article notes that one of the symptoms indicating that a vacuum pump is failing to note is the toughest brakes than usual, which may mean that the pump fails, the brake booster power will stop working well and The braking impulse will be lost. However the brakes will continue to work, although they will feel hard.

Faults can also be detected in the vacuum pump by removing the hose from the pump while the engine is running. By putting a finger over the hole, you should feel a strong suction . If you notice little or nothing will be a clear signal that the pump needs to be replaced.

In case you notice a strong suction, but not yet braking power you have, you must check the rest of the system that it does not have leaks.

The most expensive faults in a car and how to avoid them

Clutch, EGR valve, injectors, turbo, catalytic… are classic breakdowns that usually cost you ‘one eye of the face’. Whether because the piece fails or by improper use, we tell you how to prevent, as far as possible, greater evils.

In spite of performing the vehicle inspection when it touches, sometimes it is inevitable to suffer a breakdown that affects important parts of our car. Also, of course, there is the misuse of the vehicle. To all this, the aging of the car park does not help, as does the lack of maintenance. And it is that the cars of ten to fifteen years are most suffer mechanical failures, especially problems related to the engine and electric.

Since it is clear that we all try to dodge the workshop, especially to replace or repair an expensive component, there are precautions to consider that can prevent greater evils. We speak of signs that, seen in time, can save us from major problems. Finally, recommendations and clues that will help you recognize the most common symptoms that point to possible breakdowns in expensive parts to fix or replace.

Clutch: eye as you step
change the fuel filter at least every 30,000 kilometers

In manual cars it is one of the elements that most breaks down. To detect that something goes wrong you have to pay attention to noises and abnormal vibrations that may occur to engage or disengage. For example, a pronounced hardness and a long pedal stroke indicate that the part is coming to an end. Clutch replacement can cost, depending on the model, between 500 and 1,300 euros.


Prevent damage to the clutch passes take care of him, releasing him gently to get the fly and avoid, at all costs, pedal in full circulation (even slightly), or keep in gear to drive stopped, clutching, of course, thoroughly . Some taxi drivers, for example, manage to extend the life of the clutch over 300,000 kilometers avoiding these practices or driving in a way, say, “sporty”, with sudden changes.

EGR: exposed to soot

Attention must also be paid to the ERG (Exhaust Gas Recirculation) valve, a modern recirculation system for the exhaust gases. It is located between the intake manifold and the exhaust, so it is exposed to high temperatures and the accumulation of carbon and soot, generated in the mechanical combustion. The main symptoms of malfunction are dysfunction at startup, once pulls up, high fuel consumption, engine flooding, excessive smoke and lack of power. Replace the valve usually cost between 300 and 1,200 euros on average.


One way to prevent damage to this element is circular sporadically above 2,500 / 3,000 rpm steadily and for a few minutes at a speed of 130/140 km / h, or failing that , with the engine warm and running, Accelerate thoroughly a few times in a timely manner. That way, we will burn much of the accumulated soot.

The injectors are solenoid valves in charge of supplying the exact amount of fuel that the motor requires

Injectors: as precise as delicate

The injectors are solenoid valves in charge of supplying the exact amount of fuel that the motor requires. About 14 percent of the most complex breakdowns are related to them. The most common causes have to do with wear, but also with the use of low quality fuel and, to a lesser extent, poorly maintained. Replace the injectors has a average cost of 250 euros per piece in petrol engines and diesel 500 euros.


Properly care injectors passes using chemical additives designed for cleaning, although many brands of fuel include a percentage of additives in their fuel to remove impurities. Also, should not refueled during filling of the pumps. Eye, tank trucks recharge with power removing the sediments stored in the pump, which can end up in the tank of your car.

Similarly, do not rush the reservation: the sludge generated in the reservoir end up reaching the combustion chamber, forcing the pump and nozzle clogging. Care also with biodiesel: absorbs water and moisture, and can accelerate oxidation and corrosion of the components. Often, you may have fungus or bacteria in the ducts that clog and deteriorate the injection.

Finally, change the fuel filter at least every 30,000 kilometers: retains impurities and water from fuel. Doing so is much more economical than cleaning, repairing or replacing the engine injection. And controls the revolutions always traveling at less than 2,000 rpm generate more soot and provoke vibrations and premature wear of the injector system. If you notice anomalies, go to the workshop soon.

Catalyst: filters and injection are vital

Something more economical to repair, although involving a complicated process, is the catalyst, installed in the exhaust system. Its function is to reduce the pollution generated by the gases after combustion. It is a key element, because of its good performance depends on the reduction of environmental impact. What’s more, if it goes wrong we can break down the ITV.


We can perceive fault in the catalyst if we notice a lack of power, the car stalls often clanking at the bottom of the vehicle or out of thick smoke and strange odor from the exhaust. Change the catalyst does not come out for less than 200 euros (many are around 800 and even exceed 1,000 euros). And is that the materials used in its manufacture, platinum and palladium, are expensive.

Use gasoline of good quality and moderate practice driving lengthen the life of the catalyst. Same as bringing the injection system to the test. Even allowing the car to idle for a few seconds before starting it will work well, such as changing the mechanical filters when appropriate and stopping in time any leakage of oil or coolant. Being an element that works at high temperatures, it is necessary to avoid parking on dry stubble that could get to burn.

Turbo: better without haste

Overfeeding, which injects greater flow of intake air from the motion generated by the turbine exhaust gas suffers lubrication failures or excessive carbon powder in your ducts. In addition, as it can reach 750 degrees of temperature and turn at 100,000 revolutions per minute, the heat, the pressure and the speed with which it operates generate an ideal cocktail to cause breakdowns. The price of a turbocharger varies between 800 and 1,400 euros.


Caring for the turbo passes by leaving an instant mechanical idle after starting until the piece is well lubricated (and the same to turn off the engine). Its internal bearings allow it to rotate fast, but as they are lubricated with the engine oil if you turn off the engine it will continue to spin by inertia without lubricant, and you will suffer premature friction and wear. In addition, and especially in winter, should not rise much speed cold (less than 80/90).

Noises when turning, rattles: Problems and Solutions for your cars

Symptoms that something goes wrong

Today I have the impression that solve some mysteries in one article: “I hear a horrible noise when turning,” “the rattles sometimes steering wheel, and is heard as if something were scratching below the engine” … It will be symptoms of different breakdowns, and seeing the little car can guess, but many of these descriptions usually come from the same disease: the constant velocity joint .

It is a matter of importance, because the stop turning the wheel, ducking and keeping an eye on the inner side of the wheel we were quiet, or go to the workshop. In the case of cars with rear-wheel drive or it costs more to see and have to drag the belly on the ground, but it is difficult to catch the fault before the face. You catch him in time mean € 100 and expected to all parts of the constant velocity joint break takes about 600 € .

noise when turning the steering wheel

What is the constant velocity joint?

Together fixed constant velocity, together scrollable constant velocity ball and scrollable tripods … Engineering has been tumbling toward more elaborate systems, although it is clear that the force that makes the engine has to reach wheels, and this is done with a rods which are the central block to the tires that make the drive.
Each ‘stick’ is called shield . And the bearings will rotate as slowly and as fast as the power of our car will allow us and as we demand the accelerator.

This very logical question being exposed, one can only expect that the constant velocity joint is the connection between the drive shaft and the wheel. Within the constant velocity joint there are several pieces, and it is best that we stay out of the complex details, because this inner part changes greatly depending on vehicle model; with the purpose of not straying constant velocity joint must be thought of as a joint limb of a person ; as if they were an elbow or a knee or an ankle or wrist.

Seen this way, we get the idea that within our joints are no bones, cartilage, tendons, ligaments … And especially lubricating fluids so that the movement is smooth and natural.
The same applies to the constant velocity joint. It is covered with a rubber skin, with wrinkles that give appearance of accordion, and most manufacturers call ‘bellows’ or ‘dust’ . It is a protective layer must be snug and perfectly embraced so that no thickening of the constant velocity joint escape and, especially, to keep out stones, sand or other objects that end up leaving battered parts of constant velocity mechanism .


The life of the constant velocity joint is expected to be as long as the car itself, but something else is the bellows; It is a simple rubber, and is decaying. Depends on the use, maybe the dust stretches his life up to 100,000 kilometers . Although if you live in areas with many dirt roads, or where it snows often and salt to asphalt strip, the material of the bellows becomes dry and cracking before. There are cases in hostile conditions and intensive use where the 40,000 kilometers stays in state replaced. So you have to take a look at each annual review; with overalls, a board can rob, and so affect the drive shaft at a point that will not be the thrust of the engine to the wheels. And here the cost of repair is raw.
Technicians also have been making their tests with the fat that gives ease the movement of the constant velocity joint. There should be no excess or defect, and qualities of viscosity and durability opened many debates. It is quite common today mixed with a chemical compound of fatiguing name to write and pronounce oils are used: molybdenum disulphide. This porridge pharmacist what I have come to inquire, is the one that best fits almost all types of constant velocity joints.

Ford seeks new momentum with carbon fiber

Ford was working to increase the efficiency of their models through the use of carbon fiber we knew at least as far as declaration of intent. This is what was announced almost three years ago when the US manufacturer and Dow Automotive Company joined this purpose.

That same year, the Dow itself was a partner in Turkey in this area and thus was born DowAksa. Now, the association becomes more formal, because the alliance has actively joined the Institute for Innovation and Advanced Composites Production ; and moreover, we started and see some of the results of the work of Ford.

Ford and DowAksa are accelerating joint research to develop high-volume manufacturing techniques for automotive-grade carbon fiber

Little change in the objectives that arose in 2012, and govern this area of ​​the industry. The idea is to lower the production process to incorporate carbon fiber without the final price of the vehicles affected.

Please note that Ford has made ​​it clear that their research stop there. We mean that, for now, we should not have any illusions with possible applications to Ford of carbon fiber to their electric engines that are to come, as it did BMW. And is that Ford in its bid states that apply carbon fiber to reduce weight, improve efficiency and consumption, and not sacrifice performance .

In any case, as I have already mentioned on other occasions carbon fiber is a material that attracts many benefits for manufacturers. For example, in the ease of incorporation into production processes. Ford estimates that, compared with steel, they can save 50% weight in the vehicle components.

Poor tire pressure increases fuel costs

According to studies by the manufacturers and tire dealers can spend up to 50 liters of fuel over a year for not wearing the proper tire pressure, equivalent to almost a full tank and around 70 euros in petrol or diesel.

Billions wasted fuel

If we add the excess consumption of all the vehicles each year with tires not recommended by the manufacturer proper pressure we can conclude that consume up to 775 million liters more, equivalent to 1,000 million euros could be saved with simply take the proper tire pressure.
tire pressure increases fuel costs
Besides the increased expenditure on fuel, without proper tire pressure deforms before, is more prone to punctures and life expectancy is reduced. Also, especially in warmer seasons, as in the summer months, are more frequent blowouts tire pressure less adequate, one of the main causes of accidents.

Periodic reviews

The tire manufacturers and distributors are advised to check the status of the gums frequently to ensure safety at least every 15 days during the summer months and whenever you go on a trip. In virtually all service stations there manometers to do this, but warned that some are not in good condition and can be misleading, so we recommend making checks on specialized workshops, where such operations are usually performed no cost for the driver.

When should you dispose of your car battery

The car will not start, and everything points to a defective battery. Charging the aged can no longer current memory – what to do now? Do not throw the battery in no case in the household waste, but to see that you dispose of your car battery properly.
Dispose car battery properly and reap deposit money
Car batteries contain various toxic substances such as lead and acids and add if not properly disposed of serious damage to the environment. Therefore, the final journey of a car battery does not go into the house garbage bin, but to waste. There are different ways you can dispose of your car battery properly. The easiest way to deliver the battery recycling center is. So you can be sure to have everything you done possible that the current memory disposed of in an environmentally friendly and can give your car with a clear conscience a new battery. About the opening times of the recycling center informs your household waste disposal service or the competent local public office. If the transport before the recycling, it is important that the old car battery in the vehicle to accommodate properly. Make sure that it does not tip over during the tour because the battery to leak able. There is nothing wrong if you place to protect the trunk carpet a thick layer corrugated cardboard, the old car battery, the dirt and may Escaping fluid fields.

Dispose car battery properly and reap deposit money

After you have disposed of their car battery correctly, you will receive a receipt for the delivery. Those can be in the company where you once bought the current memory, submit and appreciate your disposal you Attributable deposit. Of course you will need the receipt and submit it. Therefore, keep your receipt when purchasing a new battery well. In Germany, the so-called battery regulation governs the return and recycling of duty batteries. If you return the old car battery, you get back the deposit fee of 7,50 EUR. What this means for you: You buy a new battery, bring the old car battery, and the seller subtracts the deposit fee on the purchase price. Pursuant to applicable law, the dealer must take back car batteries, regardless of whether you have your bought from him or elsewhere.

Buy car battery – let your old alike since

Because the battery take-back, however, depends on whether the seller has the old car battery in the offer of his employer, it is recommended to exchange the old battery where it was bought. To go always safe and come without problems to enjoy the deposit fee to get. Create a new car battery, without a decommissioned to make, are also computed deposit fees when buying. If you wish to dispose of the old car battery without having to buy a new one, you get logically, the deposit amount paid in cash. It is worthwhile properly the opponent for recycling the disused reservoir of energy, because you do good for the environment and engage even some euros.
