When should the antifreeze oil be changed, and how long should the car cooling antifreeze oil be rep

When the temperature is below zero, you should change the antifreeze oil.

Antifreeze engine lubricants need to be able to maintain the normal flow of lubricant molecules at low temperatures. The SAE10W 30 and SAE10W 40 are all good antifreeze viscosities.

75% of the wear of the engine comes from the 2 5 seconds of starting the car, so not changing the antifreeze lubricant in the cold winter will cause the starting wear of the vehicle to increase.

Cars generally change the antifreeze engine oil before entering the winter. As we all know, the oil used in summer is very strong, but in winter, the oil needs to be changed to antifreeze oil, otherwise it may cause the embarrassment of the vehicle not being able to start.

At present, there are many car maintenance products in China, antifreeze engine oil is no exception, when the owner buys, we must strictly check whether the oil and the car match, because different models of cars, the oil model required is also different, in addition, the owner also needs to pay attention to whether the oil is authentic, so as not to buy inferior engine oil, causing damage to the vehicle. When the owner prepares the antifreeze oil, if he can't change it, he can take the authentic oil he bought to the car repair company and ask a professional master for help. If the owner is to the 4S store for maintenance, the technology has a certain guarantee, but ** is slightly higher; If the car owner is replaced by a car repair company that is not at a good level, it is necessary to change the oil carefully and cause the car to fail to start.

You don't have to go to 4S anymore, you can study here more and change the oil outside.

Summer oil will be changed at the end of April and winter oil at the end of October.

If the temperature is above 10 degrees, you can use summer engine oil.

As we all know, the winter temperature in the north is relatively low, and the winter is relatively early. When the temperature is below zero, in order to ensure that the car can start and run normally at low temperatures, it is recommended to change the antifreeze oil, and the Northeast region generally needs to consider changing to antifreeze oil around November.

Due to the relatively low temperature in the north in winter, the requirements for low temperature fluidity of engine oil are relatively high, and it is recommended to use engine oil below 5w mark, which can effectively prevent freezing. Generally, the engine oil with the W logo model is the winter oil, and the number in front of the W represents the low temperature fluidity of the engine oil, the smaller the number, the lower the freezing point, the more resistant to low temperature, and the better the low temperature fluidity.

If the oil is changed in winter, if it is in a cold state, the oil will be affected by low temperature, and the fluidity will become poor, which will cause the old oil to be unclean. At this time, it is necessary to heat the car properly, when the oil has a certain temperature, its viscosity will be lower, the fluidity will be higher, and the oil sludge inside the engine will be softened, so that the softened oil sludge can be discharged together with the old engine oil, and the oil discharge speed will also be accelerated, which improves the work efficiency and ensures that the old engine oil can be put more cleanly.

However, it is necessary to pay attention to avoid scalding, and also pay attention to the amount of new engine oil to avoid the liquid level rising after cold driving, and oil leakage.

Need. Be sure to pay attention to the type of engine oil and the amount of oil.

Engine oils can be classified into different types according to their viscosity and quality. If your car is used in the cold region of Northeast China and has undergone regular maintenance before winter, then the oil used is likely to be a model that is resistant to low temperatures and performs better in a cold start environment. However, as the temperature warms up, changing the appropriate grade oil will ensure that the engine is in optimal working order.

Car owners who are not involved in changing the oil label must not be careless. When the vehicle is fully cooled, you can check the scale of the dipstick yourself, and if the oil level is below the minimum value, you need to add it. Of course, if the specified oil change time has been reached, it will be more thorough to go to the store to change the oil thoroughly, replace the oil filter element at the same time, and clean the oil circuit.

Yes, antifreeze oil has a lower viscosity to protect the engine in winter.

When the car is parked overnight in the cold outside, the oil will flow back into the oil pan, and the oil will become less fluid at low temperatures, so wait a while before starting the car after turning on the power to reduce engine starting wear.

In addition, turning on the air conditioner before the water temperature rises is also more fuel-intensive, and it will also increase the burden on the engine, so it is not advisable to use the air conditioner to blow the windshield just after starting. After the car is warmed up, turn on the windshield heating function on the car, and start the de-icing work after the ice ballast on the body and glass has gradually melted, which can do more with less.

The engine oil that has been used for a long time, has a black color, and has poor adhesion should be replaced to ensure a smooth start of the engine.

Summary. Hello, how long is the replacement time of car cooling and antifreeze oil, which is generally about 40,000 kilometers in two years.

Hello, how long is the replacement time of car cooling and antifreeze oil, which is generally about 40,000 kilometers in two years.

Isn't it life-long replacement?

Pro, free replacement once every two years.

The role of antifreeze is to cool the engine. In the past, water was added to the simple side engine, which was called cooling water. But in the winter it can freeze, and there are other problems.

Nowadays, all of them use a specially formulated liquid with antifreeze function, which is called antifreeze, but some people are still used to calling it coolant. It's all the same.

And so on.

I added which closed cooling oil, Li crack to change the cooling oil is the manufacturer said that it is free of replacement for life, and now the liquid level has been reduced a lot, so I asked whether the antifreeze cooling oil needs to be replaced.

Dear Yes. Free replacement.

Cooling oil is not a normal coolant!

The cooling oil is designed with a kinematic viscosity that changes with the base temperature, and the engine temperature is below 100, and the heat dissipation is sluggish, which can quickly warm the engine and reduce reactive power loss; And above 100, super heat conduction.

Ask if the liquid level is lower than the standard, whether it will be replaced or supplemented. Supplement.

When different cars leave the factory, the added antifreeze is different, some manufacturers use more generous, the antifreeze is used for a long time, and some even use waterless, like this antifreeze can be managed for a long time, and even can be maintenance-free for life. However, in order to save costs, a considerable number of cars will use antifreeze slightly worse, so it will have a replacement cycle requirement.

For example, the antifreeze of many Japanese cars can be more than 200,000 kilometers, generally speaking, the more expensive the car, the higher the quality of the antifreeze, the longer the replacement time, the cheaper the car, in order to save costs, the use of antifreeze will be relatively poor, the replacement time and mileage will be relatively short, so how long to replace the antifreeze, there is indeed no unified standard.

As we all know, the northern region has a cooler winter and an early onset of winter. When the temperature is less than zero degrees, in order to better ensure that the vehicle can start and run normally under low temperature conditions, the antifreeze engine oil is dismantled and replaced in the three northeastern provinces, and the three northeastern provinces must be considered to be replaced with antifreeze engine oil in November.

Because the temperature in the northern region is relatively low in winter, the low temperature fluidity of the engine oil is very high, and it is proposed to use the engine oil below 5W model, which can reasonably prevent freezing. Generally, the engine oil with the W mark model specification is the winter cooking oil, and the number in front of the W means the low temperature fluidity of the engine oil, the smaller the data, the lower the ice degree, the more resistant to low temperature, and the stronger the low temperature fluidity.

Change the engine oil in winter, if it is a cold car situation, the oil will be harmed by low temperature, and the fluidity will decrease, which will lead to the old oil not being clean. At this time, the car must be moderately warmed, when the oil has a certain degree, its viscosity is lower, the fluidity will be higher, and the sludge in the car engine will be soft, and then the sludge in the car engine can be discharged together with the old oil judgment, and the rate of adding some oil will also be accelerated, which improves the work efficiency and ensures that the old oil can be put more neatly.

However, special attention must be paid to prevent burns, and it is also necessary to pay attention to the amount of new engine oil to prevent the liquid level of the cold car from rising and oil leakage.

Millions of car purchase subsidies.

<> "How often should I change brake fluid, engine oil and antifreeze?"

The maintenance of the car has always been a concern of the car owners, because after all, we spend a lot of money to buy a car, and no one wants to have problems with their beloved car, so maintenance is very important. One of the most important points in maintenance is to change the brake fluid, engine oil and antifreeze regularly, but how often should you change them? In fact, it is very resale, and many car owners do not know very well.

First of all, let's talk about the time to change the brake fluid. In fact, many car owners do not know much about brake fluid, but brake fluid is a more important fluid, once the brake fluid is insufficient or there are some problems, the consequences are unimaginable. The brake fluid generally needs to be replaced once after running 60,000 kilometers, and the owner needs to go to a professional to replace it, because if you change it yourself, it is likely to cause air to enter the brake pot, which will affect the use of the brake.

Generally speaking, everyone drives differently, but no matter how much they drive, if it is less, they should change the brake fluid once every 3 years.

It's the time to change the oil. Generally speaking, everyone will say that you should change the engine oil once after running 5000 kilometers, but this is not very accurate. We also need to take a look at what kind of engine oil we use, which is generally divided into mineral oil, semi-synthetic oil and fully synthetic oil.

Mineral oil is changed once after 5,000 kilometers, while semi-synthetic oil does not need to be changed once after 5,000 kilometers, and is generally replaced after 7,500 kilometers, and fully synthetic oil is controlled at 10,000 kilometers to replace once. But if we're driving on bad, bumpy roads a lot, then the oil can be changed more often.

Finally, there's antifreeze. Antifreeze is used to help initiate antifreeze and cooling, and it is generally enough to replace it once every 2 to 3 years. There is nothing noteworthy about this, and if there is one, it is that many car owners may forget when they last replaced.

Therefore, car owners should pay more attention to their cars.
