You have probably heard this debate on more than one occasion. What is better, water or antifreeze for the engine cooling circuit? Well then we will try to clarify some doubts on this subject. The first thing to say is that the cooling system is of vital importance to your car and that its maintenance should be the best possible.
Because it is responsible for evacuating the high internal temperatures that occur in the engine. Up to 2,000 degrees can be achieved during the fuel explosion inside the cylinders. Subsequently, that very high temperature will decrease when the expansion stroke occurs and in the exhaust phase it will continue to fall to 150 degrees.
The cooling system will therefore be responsible for reducing the average temperature of these elements. Without this system dilations and deformations could be created in different parts of the mechanics. Some examples could be the rubbing of the pistons with the shirts of the cylinders , to burn the gasket of the cylinder head and even that one of the weakest pieces was cracked.
In the cooling circuit there must be a liquid , which will be responsible for absorbing the heat emitted by the engine and therefore that the temperature will drop. That is where our two main options , water and antifreeze liquid appear, and the doubts of which to use. A few years ago, water was simply used, but then came the antifreeze liquids that mix water and some additives to improve their capabilities.
Therefore, yes we can pour water into the cooling system and it will work. However, it will not be the most recommended option. Water contains oxygen (H2O) and therefore may oxidize some of the parts. It also changes state with temperature and this means that it can freeze below 0 degrees or evaporate if it exceeds 100 degrees. Also note that you can not use tap water, which contains lime and could clog some parts of the circuit. In any case, if used, it would have to be distilled water.
The antifreeze liquid will have advantages over distilled water thanks to the additives we said before. This will ensure that the liquid does not freeze until about 30 degrees below zero, in addition to raising the boiling point by 20 or 30 degrees. Another positive point is that we can forget the rust and lime that could accompany running water.
This means that the antifreeze fluids guarantee a better functioning of the refrigeration system and will also improve its useful life. We will also ensure a better cooling with these liquids thanks to its improved properties. Although of course it will be acceptable to use distilled water if we need it or if we have any emergency in order to avoid major evils.
Maintenance in this case will not be very complex. It is advisable to check the level and visual state of the coolant frequently. It must be remembered that the proper functioning of the motor will depend on its cooling. Usually the time to replace it is usually between two or three years , something that will have to be reviewed in each manufacturer’s maintenance book.
In this video tutorial you can see how to clean the cooling system a vehicle. It is a simple action and many will know. In any case if there is a problem of more seriousness in the refrigeration system the best will be to pass through the hands of a professional.
When we finish a trip, especially in summer, or when we have left it several days our windshield always asks for a shouting wash. Doing this is easy, but it may not be as simple as it seems because given the dryness of the environment, removing the remains of either mosquito slaughtered against the glass or removing the accumulated dust on its surface can cost us much more than expected.
In addition, not always that we apply water and rub the remains are removed, but the only thing we do is contribute to spread them over a surface even greater than the one they occupied previously and make the vision even more difficult. This is what usually happens when we operate the windshield wipers and we intend to remove them only with them and with the windscreen wiping liquid of the car.
You can incorporate Advanced driver-assistance systems (ADAS systems) in the windshields, as these have become an important security element that you also have to take care of. Its sensors pick up information through the windshield for the operation of many functions and systems of the car (especially for those who bring us closer to autonomous driving more and more) and just as your vision of the environment is reduced at that time, your Data capture could also be affected. So, bringing the crystals clean and well washed is increasingly necessary.
The specialist repair and maintenance of car glass offers low cost preventive treatments that same as they get rainwater or snowflakes to slide better when falling on the glazed surfaces, prevent the remains of the insects or the dust that hits them will stick to them. With this, we will achieve that the cleanings are much faster and easier.
If you opt for the more traditional method, water and soap, the best thing to remove mosquitoes is to resort to some cleaning product that we usually have at home and, conveniently mixed with water, distribute it on the surface to be cleaned. It is important to let the product act, so do not proceed to rub immediately but leave enough time before using the cloth.
To distribute the cleaning liquid to be used as well as to rub on the glass you must use suitable elements that do not scratch or deteriorate the surface of the glass. If you use very rigid rags or brushes with very hard bristles, when contacting the elements deposited on the surface of the glass and moving them with force you will move the harder particles and you will scratch the crystal.
If you did what we told you, it will be much easier to remove mosquitoes from the windshield. If you are also in a place where you can use hot water (never boiling, as this can damage or even cause the glass to explode), it will still be easier. Always use a soft cloth or brush with soft bristles and do not exceed the pressure applied on the glass always move them on the surface with rotating movements. If even accumulated insects or dust remains, mixing water with sodium bicarbonate in a microfiber cloth to clean also produces good results.
If what has accumulated on the glass is the grit of the beach that lifts the air, the best system you can use is the same that took you there: blowing air. But of course, not all of us have enough lung capacity for this, nor a compressor by hand. If you rub directly scratch the glass with the consequences already commented. The best thing to do then is to first pour water without too much pressure from the top of the windshield to remove as much of the grit from the same and then clean it normally. In these cases carrying a bottle of water in the trunk is a solution, especially in summer, it is not bad to adopt.
All the elements that make up a vehicle have a determined half-life, many of them (those of a more technological nature) even have a programmed half-life, what is known as programmed obsolescence. Well , all these elements from time to time must be replaced to extend the life of the car and that it continues to function properly.
The question we ask is, are original spare parts or generic spare parts? Here are some tips to help you make the decision.
The original spare parts are always more expensive than a generic spare parts and as a rule, the vast majority of generic spare parts can not match the performance of an original ones.
The original spare parts also have the advantage that they are specific spare parts for the car models and that the evolution, the design and the technology of the same goes hand in hand with the one of the vehicle. This does not mean that there are no generic spare parts that are effective, but purchasing an original spare part is an absolute guarantee, in the majority of cases, of total safety.
A practice extended by a good part of the drivers is to acquire original spare parts the first times that they have to face a situation of this type, later, after a few years have passed since they acquired the vehicle, opt for generic spare parts.
On the other hand , the automobile companies are nourished of other auxiliary companies that supply them of elements necessary for the manufacture of vehicles. These companies are the ones who in turn manufacture specific spare parts for companies or generics for any model of vehicle , but they do it always respecting some minimum standards of quality that the market demands them and putting all its technology to the service to generate sufficient income.
As important detail, the American, European, Japanese and Koreans cars have all elements of complete safety. It is true that there will be some isolated cases that do not respond with a guarantee, but as a rule there are vehicles with reliable parts. This is not the case with Chinese originals, the Chinese copy and copy everything they see in the market but with very economic forms that can sometimes pose a risk to driving.
The brakes are one of the most important active safety elements with which the vehicle counts . They are used every time you drive and although they are becoming more complete and present a more innovative technology, over time they wear out. So here are some tips to prolong the half-life of these elements.
First, practice responsible driving. A responsible driving is to drive with less abruptness, respecting the norms of speed of the way, maintaining the safety distance, not committing infractions or misunderstand and especially, whenever possible, to use the motor brake.
The engine brake is a good solution so that the brakes are not hot, it should be used in prolonged descents, in which you can reduce the speed using the gearbox, and thus adapt more naturally to the speed of the track.
Another aspect to take into account are the vehicle witnesses , most vehicles currently have intelligent systems that warn you of wear and tear of the brake system . It is advisable not to let these warnings pass.
Finally, the touch of the pedal is a fundamental clue. If it vibrates, it must be stepped on hard or it sinks, brake pads or discs may be worn, unbalanced or there is a leak in the brake circuit.
As you see, maintaining a calm and intelligent driving can prolong the half-life of all the elements of a vehicle, including the brakes, but sooner or later it will be time to replace them.
A final piece of advice, when it comes to replacing a damaged part of the vehicle and incorporating a spare part, is preferable to leave it in the hands of professional mechanic, or at least in people who have certain notions about this science. On the internet in any case you can see different videos tutorials to carry out these maneuvers.
The tires are a fundamental piece to maintain the good condition of the vehicle. This time we will tell you some tips intended to choose well the tires of the car, as the current offer of these parts is very wide. In the market you can find new, prestige or white-brand tires and second-hand or retreaded tires.
As with other sectors, on the internet you find online stores dedicated to the sale of tires. On such websites you can easily choose the type of tire varying between width, height and diameter, as well as specify the type of tire (summer, all seasons, winter, etc.). They also have tires for motorcycles and other parts and spare parts for vehicles.
As a general rule, manufacturers recommend that you use the standard tires fitted with the vehicle, this is an option, but if you have to replace them, here are some points to consider when choosing the type of tires.
The lateral code of the wheels is the one that specifies the type of tire that has mounted the vehicle . There are three numbers and two letters : the numbers refer to the width of the tire, the relationship between the height and width of the wheel profile and the inside diameter in inches; While the letters refer to the structure of the wheel and the speed code.
Climatic conditions have a significant effect on the condition of the tires, so it is necessary to know the predominant climate of the places where it is normally circulated. Usually we differentiate between summer tires, winter tire or mixed tire.
Depending on the type of driving you practice you will need one type of tire or another. Similarly, the state of the roads is, along with the weather conditions and the type of driving, another great factor to take into account in the choice of tire.
As final tips, it is important to conduct periodic reviews of tire condition, experts advise two annual reviews. And finally, before starting a long-distance journey, it is essential to check and adjust the tire pressure.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
