What brand of antifreeze is good for Jetta cars

It's not very easy to change.

First you need to turn on the thermostat.

Remove the sewer pipe and drain the water.

The sewer pipe is a bit strenuous on the side of the booster pump.

When adding new antifreeze, be sure to remove the water pipe on the water tank from the bottom of the water pipe.

Add new antifreeze to the tank from the water supply pipe.

In this way, it is not easy to produce air blockage.

After connecting the water pipe, add antifreeze to the kettle.

Normally.

The water temperature will not be high.

After getting in the car. You have to watch carefully.

The kettle has to be back piped.

Backwater situation. If there is no backwater.

In general.

It's that the return pipe of the cylinder is blocked.

That's trouble.

It's best to go to the workshop to change it.

Now Tianjin's 4S points are on sale.

Change the antifreeze. That's only about 100 in total.

Changing the antifreeze thoroughly is a three-step process:

1. Inspection. Before completely replacing the antifreeze, it is necessary to do a comprehensive inspection to see if there are traces of leakage in each pipe and whether there are cracks, the key is to check the five-way water pipe, the five-way pipe is named because there are five interfaces connecting various parts, and the antifreeze is distributed to different parts of the car after flowing through the five-way pipe. If there is a leak of antifreeze in this section, the water pipe should be replaced or the connection should be re-fixed according to the situation.

2. Drain water. Drain the old antifreeze and wash the liquid passage with clean water. Add clean water to the antifreeze to replenish the tank, then fill the tank with clean water so that the water flows continuously through the engine cooling system, and then idle for 3 to 5 minutes to circulate the water.

The water that starts to flow out of the pitcher is a little pink, and continue to pour in clean water until the water that comes out is clean. Note: Don't forget to dismantle the warm air water pipe and clean the water in the warm air tank.

3. Change the new solution.

After draining the water for about 1 hour, a new antifreeze is added through the water pipe of the tank (radiator), which is a method to allow the antifreeze to flow into the tank quickly. Then add another bucket of antifreeze to the antifreeze tank, add it until the antifreeze tank is almost full, and drive for about 10 minutes, at this time, the cooling system has removed part of the air, the liquid level has dropped, and then add the antifreeze to it, and fill the highest mark of the storage tank "maxt".

Before replacing the antifreeze completely, Jetta should do a comprehensive inspection to see if there are any leaks, cracks, exhaust and other traces of seepage in each pipeline. It is not recommended to add antifreeze on your own. The full name of antifreeze should be antifreeze coolant, which means antifreeze coolant, which can prevent colds.

The coolant froze and ruptured the radiator, damaging the engine block. In the normal maintenance of the car, the engine antifreeze needs to be replaced every year of driving, and the frequency of antifreeze replacement for special vehicles should be higher. There are three steps to completely changing the antifreeze:

1. Before replacing the antifreeze completely, do a comprehensive inspection to see if there are leaks and cracks in each pipeline. The focus is on inspecting the bottom bracket, which gets its name from the five joints that connect the various parts. After the antifreeze flows through the bottom line, it is distributed to different parts of the car to play a role.

2.Drain the old antifreeze and clean the channels with clean water. Add clean water to the antifreeze refill tank, then fill the tank with clean water so that the water continues to flow through the engine cooling system, and then idle for 3 to 5 minutes to circulate the water.

At first, the water coming out of the tank is a little pale pink, and continue to fill in fresh water until the water comes out clean. 3.About 1 hour after replacing the new liquid with water, add new antifreeze from the water pipe of the water tank, which is a method to make the antifreeze flow into the tank quickly.

After talking about the ridge, add another bucket of antifreeze to the antifreeze tank until the antifreeze tank is almost full, and drive for about 10 minutes. At this point, due to the partial air mass, the level of the cooling system is lowered, and then antifreeze is added until the highest mark of the reservoir is full.

Where to add antifreeze to the Jetta car.

Jetta added to the tank. Antifreeze is a type of coolant containing special additives that is mainly used in the cooling system of liquid-cooled engines. Antifreeze has excellent properties such as antifreeze in winter, boiling in summer, anti-scale and anti-corrosion all year round.

Here's how to change the antifreeze:1. Before replacing the antifreeze, check it thoroughly to see if there are leaks and cracks in each pipeline.

The focus is on inspecting the bottom line. After the antifreeze flows through the bottom line, it is distributed to different parts of the car. If there is an antifreeze leak in this area, the water pipe should be replaced or the connection should be re-secured according to the situation.

2.Drain the old antifreeze and wash the liquid passage with clean water. Add clean water to the antifreeze refill tank, then fill the tank with clean water so that the water flows continuously through the engine cooling system, and then idle for 3-5 minutes to circulate the water.

At first, the water coming out of the tank was a little pale pink, and the fresh water continued to be filled until the water came out clean. Don't forget to remove the hot water pipes and wash the water in the hot water tank. 3.

After draining water for about an hour, add new antifreeze from the water pipe of the tank (radiator), which is the way to make the antifreeze flow into the tank quickly. Then, add another bucket of antifreeze to the antifreeze tank until the antifreeze tank is almost full, and drive for about 10 minutes. At this point, the liquid level of the cooling system has dropped due to the exclusion of some air bodies.

Then, antifreeze is added to the tank and the highest mark of the reservoir is filled with MAMT.

Four liters of Jetta antifreeze is sufficient, that is, antifreeze coolant, coolant with antifreeze function.

Antifreeze is an antifreeze coolant that has the function of anti-guessing segment freezing. Antifreeze prevents the coolant from freezing the radiator and freezing the engine block or cylinder head when the cold winter months are stopped. Many people think that antifreeze is only used in winter spikes.

In fact, antifreeze is not only used in winter, but also all year round. Different manufacturers produce different internal additives in antifreeze. Once mixed, physical and chemical reactions can occur, resulting in damage to the cooling system.

Therefore, when adding, it is best to add new antifreeze after the original antifreeze has been fully released.

Car antifreeze is generally replaced once a year with high-quality antifreeze, while those vehicles with short driving times can be replaced every two years or every 30,000 kilometers. The full name of antifreeze should be antifreeze coolant, which means antifreeze coolant. Antifreeze prevents the coolant from freezing the radiator and freezing the engine block or cylinder head when the cold winter months are stopped.

Antifreeze has the following protective effects:

1.It acts as an anti-corrosion factor in protecting the components of the cooling system.

The second is to prevent fouling and avoid reducing the heat dissipation effect of the radiator.

3.Make sure the engine can work within the normal temperature range.
