How the thermostat works in a vehicle

The thermostat in a car is responsible for maintaining a proper and constant engine temperature, which needs to work with a coolant temperature of approximately 90 °. The thermostat is a control element that opens or closes a circuit depending on the temperature. It is vitally important in the engine; it is responsible for maintaining the temperature of the engine properly and consistently. The thermostat controls the passage of the coolant from the radiator to the engine so that it reaches its ideal temperature operation in the shortest possible time, in this way can save fuel.

The spring expands when the coolant temperature increases; when the low temperature the spring contracts, this way the opening and closing necessary to control the flow of the refrigerant takes place.

Common failures in the thermostat

The faults that can occur in the thermostat are that it stays stuck and can be open or closed, the two faults can cause problems. The open thermostat: when the thermostat stays open the engine runs cold, it does not store the coolant in the engine to keep it and reach its ideal operating temperature. When the thermostat stays open, an excessive increase in fuel consumption is generated.

The closed thermostat: when the thermostat gets stuck in its closed position the motor overheats because it is not allowed the entry of refrigerant to lower the operating temperature in the motor. When the thermostat stays closed the motor overheats and can cause damage to the cylinder head and cylinder head gasket and can cause engine damage due to overheating.

Rust or dirt: happens when the engine is given an inadequate formulation of the coolant; the proportion must be 60% of refrigerant per 40% of water, if the mixture is improperly made or only water is applied, rust and dirt are produced in the thermostat, causing it to seize up.

Damage caused by overheating of an engine

The temperature with which the engine works is a factor that all drivers must be aware of when driving day after day; this detail is extremely important because overheating of it can cause serious damage to the engine starting with the rupture of the head gasket, the deformation of the face of the head, the deformation of the cylinders, an important wear on the rings, and depending on what temperature is reached, there may be problems such as serious damage to the cylinder head, in addition to the possibility of finding significant damage to the crankshaft elbows on connecting rod and bank.

This is such a delicate point because, sometimes after an overheating of the engine, we can begin to experience problems with engine power and low or moderate oil consumption. The engine must work at an optimum temperature for its proper functioning, it must not be a very low temperature because we lose optimization of the mixture, which increases the polluting emissions and increases the fuel consumption.

The cooling system of the engine is composed of several elements or devices that help to maintain the temperature usually between 84C and 96C degrees, such as the radiator, water pump, thermostat, electric fans a good engine coolant that flows go through a circuit from the engine block around the cylinders extracting the heat which is diminished by the electric fan by means of a thermo-contact or in cars with recent technology through the engine or computer control module.

The overheating of an engine is usually a symptom that tells us something happened and this is where the diagnosis comes in search of the problem. As it is known the cylinders are surrounded by a refrigeration circuit, one of lubrication and also the place where we find the compression chamber and these three cannot be mixed or joined together, this is where the gasket of the cylinder head comes in, as 1957 nash metropolitan gives independence to each circuit.

Damage to this package means that the refrigerant can mix with the oil or enter the compression chamber. If the refrigerant escapes to the lubrication circuit it will mix with the oil and visually we will see the white oil. If the refrigerant leaks into the compression chamber you will feel a considerable loss of power and visually you will see white smoke from the engine exhaust as excess steam, something like condensation on cold mornings.

Why use the fish tank filter?

Having an aquarium represents a series of obligations and responsibilities that contribute to the complete development and quality of life of the species that occupy that space. Its maintenance and care is not simply to maintain a beautiful environment in the eyes of external observers but to create the right conditions of healthiness The filtering material is an important element when it comes to making the water in our aquarium look crystal clear and clean of impurities. Basically, the filtering material is responsible for removing all those particles of dirt contained in the water of our aquarium. There are different types of filtering materials and each of them is responsible for a task.

Filtration System of an Aquarium

Why do you need a system that cleans and purifies the water in your aquarium?

Fish tank filter

As the aquarium is a closed biological system, the metabolic processes of living beings end up altering their composition and chemical equilibrium.

This means:

First, in an aquarium the biological activity of its inhabitants produces waste. Excretions of fish remains of food remain of plants … and organic remains in general. And in the nature, these residues decompose and process without the major problem. But in an aquarium, its composition and chemical stability eventually become unbalanced. The accumulation and decomposition of this waste end up turning the aquarium into a toxic medium for its own inhabitants. That is why water purification is vital for the health of your fish, being necessary to eliminate biological waste before it becomes toxic.

How to choose fish tank filter?

When choosing fish tank filter for your aquarium you should always resort to the best quality and that is why these fish tank filters, specially compiled by our experts from a large number of filters available this year in the market, are ideal for you. Select the one that most convinces you and install it efficiently in your aquarium. Let’s see all about the filtration of the aquarium, the types of filters for aquariums and others. This topic is intimately related to the cycling process, which I suppose you already know. Just in case, I refresh your memory.

We call maturation or cycling of the aquarium to the microbiological process by which the colony of friendly bacteria settle in the filters for aquariums. The beneficial bacteria are part of the filtering system and are responsible for purifying the aquarium water. Through a biochemical process, they degrade polluting waste before it becomes toxic. The filtering materials are elements that make their function within the filtration system of our aquarium. It is necessary to know what the functions are of the fish tank filter that performs to achieve a healthy and clean aquarium. For this, it is important to establish a balance of both internal and external agents.

Resorting to filter:

Which are essential to keep the water in the aquarium clear and its environment free of impurities that could kill the fish?

What is cloudy water?

Are those waters that due to the sudden proliferation of bacterial colonies, which grow disproportionately becomes cloudy. They can be observed with the naked eye, causing the fish cannot be seen. This proliferation of bacteria can be caused by contamination produced by the death of fish, plants, or because there has been an increase in nutrients in the water, particularly nitrates and phosphates. Other causes and the most common is overfeeding, as food residues remain without being consumed by the fish, leading to their decomposition. Everything that is broken down into fish tanks represents a source of food for these scavengers.

What are fish tank filter types?

The fish tank filter is a mechanism whose function is to circulate water through it, eliminating the impurities that it contains, thus achieving that the water is purified by passing through the different filtering materials. The purpose of having a filter in your aquarium is to recycle the water and return it clean and clear after having eliminated all the waste that contaminates the water. The fish tank filter consists of a hydraulic pump as the main element, which has the function of pumping the water through the different filtering materials, which is composed of different levels of filtration which vary according to the porosity they have.


They are those that are inside the aquarium and completely submerged under water. They are ideal for aquariums of small or medium volumes.


They are those that are outside the aquarium. This type of filters, unlike the previous one, is indicated for aquariums of large volumes. The filters according to their configuration and operation can be: Mechanical, chemical and biological.

Mechanical filtering

It is responsible for preventing those particles of solid waste that remain on the surface, reaching the bottom of the aquarium, depending on the size of the trapped to the porosity of the filters.

Chemical filtering

Its main element is activated carbon, used to change the chemical composition of water, and catch some chemical elements that damage life in the tank.

Biological filtering

Its origin is natural, that is, it is not created by the hand of man, and is based on the nitrogen cycle, making the disappearance of bacteria in a natural way. But that toxic ammonia is transformed by bacteria into another product, nitrites (NO2). Nitrites are also toxic, even in small amounts and also cause the death of fish. But luckily, there are some beneficial bacteria that appear alone and that are in charge of transforming the toxic nitrites into nitrates (NO3). Nitrates have the advantage that they are tolerable by fish and only harm them when levels are high.

Nitrates serve as a nutrient for natural plants, which consume them. But its excess accumulates in the water and causes the appearance of the annoying algae. We hope you have helped these tips to start in this exciting world of the aquarium by using the.
