Golf 6 16000 km plus coolant normal

Golf 6The newly replaced thermostat leaksCoolantIt is usually because the sealing ring or cushion at the thermostat is broken, which causes leakageAntifreezeThe thermostat in the cooling system failed, the upper and lower water pipes of the cooling system were aged, the engine pump failed due to antifreeze leakage, and the engine cylinder gasket rolled down caused by antifreeze leakage.

Use of the thermostat which golf 6 is new to change

It is specifically recommended to check as soon as possible, if the antifreeze leak will cause the engine to work at too high temperatures, it will damage the engine, because the antifreeze is responsible for the car engine.

The task of cooling is often at high temperatures, which reduce the amount of antifreeze, while the amount of antifreeze remains constant at low temperatures.

The principle that the cold car leaks antifreeze and the hot car does not leak is the same as the car has more antifreeze when the car is cold and less antifreeze when the car is hot, which is caused by temperature, whether it is a cold car leaking antifreeze or a hot car not leaking antifreeze, it shows that the user's car has an antifreeze leakage and needs to be repaired. If antifreeze is allowed to leak and the antifreeze on the car is missing, there are many consequences.

Because engine coolant is a mixture of distilled water and antifreeze, it needs to be added to the jug. Automobile coolant has anti-freezing and cooling functions, which can ensure that the car can be used normally in cold climates without freezing, and when the engine temperature is too high, it can play a role in cooling and cooling, so that the engine can operate at the correct temperature, and the automobile coolant is replaced every 2 years or about 40,000 kilometers.

The role of coolantAutomobile antifreeze has a shelf life, the shelf life determines the replacement cycle of the coolant, the maintenance manual also mentions, the general shelf life is about 2 years, this is just a reference replacement cycle, specifically according to the actual use of the vehicle to determine, if it is a business vehicle, such as a taxi, the frequency of vehicle use, the mileage of the hungry driving is more, and it needs to be replaced more frequently.

Coolant also has anti-corrosion, anti-scale and other effects, is an indispensable liquid for automobiles, vehicle engine normal temperature code lithology between 85 and 105 degrees Celsius, when the engine working temperature continues to rise more than 105 degrees Celsius, and is not cooled to control, there will be a large number of white steam boiling phenomenon, the engine boiling, the light one leads to engine overheating, heavy rotten mold car and even serious consequences such as engine scrapping.

90 degrees normal.

The water temperature gauge is displayed on the dashboard. The water temperature gauge is a digital meter, 50-130 degrees Celsius. The water temperature gauge alarm is to train or alert the owner that there is a problem with the engine cooling system or that there is a lack of antifreeze.

The water temperature gauge is a numerical display, ranging from 50-130 degrees to 90 degrees Celsius. The water temperature gauge is to display the coolant temperature, which is convenient for the owner to understand the condition of the car. When the water temperature of the car is too high, the owner needs to stop and rest, wait for the hidden temperature in the vehicle to drop to the normal temperature in the water, and then continue driving.

According to the theory, the suitable temperature of the golf should be 90 degrees, and the engine is relatively stable in such a temperature range. The full name of antifreeze is called antifreeze coolant, and its most important function is actually cooling - reducing the temperature of the engine and preventing ice formation in winter. So how much temperature is generally appropriate for early detection?

Relatively speaking, we are more concerned about when the water temperature can reach 90 degrees, which is largely determined by the vehicle engine itself. Comparatively speaking, the temperature of water with a large displacement increases quickly, while the temperature of water with a small displacement increases slowly. This point needs to be grasped by everyone.

1. First of all, after finding that the water temperature is too high and stopping to the side, it should not be turned off immediately, because there are many reasons for the high water temperature, but there is probably only one fault each time, if all other functions are turned off, the water temperature will be too high, damaging the engine, the accurate approach should be to idle the park, open the hood, turn on the heater, dissipate heat as soon as possible, and pay attention to parking in a cool place.

2. Next, we have to check whether the coolant is sufficient, this situation is likely to be that the owner usually does not care about forgetting to add it in time, and it should be noted that the owner must choose the same brand and model of product when adding coolant, otherwise it may cause chemical reaction due to different components and lead to the failure of antifreeze.

3. Then, we are looking at whether the cooling fan is running normally, and the failure of the cooling fan will cause the heat generated in the car engine at high speeds to be transferred to the antifreeze and not be dissipated in time, resulting in an increase in the temperature of the antifreeze. If the fan is stuck or the insurance is burned, you can solve it as soon as possible after the power failure, if it is a line problem, it can only be handed over to the professionals of the 4S shop to overhaul.

Extended Information: Car Radiator Function.

The function of the cooling system is to dissipate excess and useless heat from the engine, so that the engine can operate at normal temperature at all speeds or driving conditions.

The water tank is the heat exchanger of a water-cooled engine, which is cooled by air convection to maintain the normal operating temperature of the engine. Once the cooling water of the engine in the water tank boils and vaporizes and expands due to high temperature, and the pressure exceeds the set value, the pressure will be released from the water tank cover (a), resulting in a decrease in cooling water and preventing the cooling system pipeline from bursting.

When driving, you should pay attention to whether the engine cooling water temperature gauge pointer on the dashboard is normal. In addition, if the engine cooling fan fails and the water temperature of the engine cooling finger bend rises or the cooling system pipeline leaks, the cooling water may also be reduced.

The antifreeze replacement interval is 2-3 years. When you blow it clean, it will probably liter.

Automobile antifreeze not only has the function of antifreeze, but also has an important role in cooling, anti-boiling, anti-corrosion, etc., in which anti-corrosion is the key, the engine consumes the additive components in the antifreeze in the process of operation, and with the extension of time, the concentration of some components will be lower and lower, thus losing the anti-corrosion function of the engine metal. The optimal use cycle is 2-3 years.

The functions of coolant are divided into: cooling, lubrication, anti-corrosion, anti-freezing; How long to replace depends on the formula of the coolant, silicate, the precipitation of silicon can protect aluminum, but the precipitation life of silicon is about 2 years, so it is replaced once every 2 years, the usual life of organic acids is relatively long, if the original vehicle is certified, organic acids can be used for 4 years or 20w; Coolant can not be used beyond the time limit, in that case, the aluminum parts, rubber parts, water pumps, sediment control is not good, the purchase of coolant in addition to the correct formula, the choice of boiling point is also very important, domestic ordinary antifreeze can only reach about 107 degrees, the good point is about 113 degrees, the boiling point of imported products can usually reach 129 degrees, the above are glycol-based products.

Change it once every three years, and if you blow it clean, it will probably rise.

Antifreeze needs to be replaced every two years. It is best not to use antifreeze with a long shelf life, and the replacement cycle is rather short. Don't keep dragging it out because you are reluctant to buy antifreeze, and eventually cause irreparable consequences.

In addition, when replacing antifreeze, it is best to warm up the car first, and the hot car is relatively clean, and it is also necessary to remind that the brand of antifreeze should not be replaced as much as possible, and it is best to use this brand all the time at the beginning, and the quality of the same brand of antifreeze is generally not too different.

Cooling oil is a new type of engine engine cooling medium, and its basic role is to replace the traditional aqueous antifreeze to dissipate heat for the engine. According to the introduction, traditional coolant: water and aqueous antifreeze can not meet the congenital defects of engine heat dissipation:

1. The water will freeze at 0, and the pot will boil at 100. Ice can inflate the engine's water tank and cylinder block, and boiling the pot can overheat the engine until it causes paralysis.

2. When the engine temperature reaches more than 80, water bubbles should begin to produce on the cylinder wall. Water bubbles form a bubble barrier layer on the cylinder surface, preventing heat from escaping from the engine. Water bubbles are endlessly formed and burst on the metal surface of the engine block, and the cylinder block is lost in a dripping effect This is cavitation.

3. The local temperature inside the engine is too high, and the pre-ignition and detonation tendency increases, which increases the vibration and noise, greatly reduces the performance and efficiency of the engine, and forms no water and fuel consumption.

4. Electrochemical corrosion and rust and scale occur under the use of electrolyte as filial piety, which aggravates the aging rate of the cooling system and reduces the heat dissipation performance.

5. When the engine temperature reaches more than 80, the water vapor, water bubbles and water body expand, which increases the internal pressure of the cooling system. In this way, it not only catalyzes the aging rate of the cooling system, but also makes it impossible to ensure the speed required for normal heat dissipation due to corrosion. Therefore, the heat dissipation defects of aqueous antifreeze can be summarized as buried in Li

The heat dissipation performance is limited, and the overheated vertex cannot be suppressed; The engine gradually ages, so that the engine heat generation increases unabated; The cooling system gradually ages, so that the heat dissipation capacity is reduced but not increased.

It is recommended to use the latest product of coolant replacement: Huibang cooling oil, Huibang cooling oil can effectively solve the above problems and better maintain the performance of the engine. There is also the effect of saving fuel, more environmentally friendly! 500,000 km maintenance-free!
