12 Corolla change antifreeze How long does it take and how many kilometers do you change?

Generally, the replacement of antifreeze is a major maintenance, generally once every three years or 60,000 kilometers.

3 years or 6w replacement of the original factory, whichever comes first.

Corolla antifreeze is generally replaced every two years or 40,000 kilometers. Of course, this is only a reference replacement cycle, which can be replaced according to the actual use, because it is not a big problem to go one or two thousand kilometers more or extend the use cycle for about one and a half years. If the car is used intensively, it can be replaced in advance.

However, if the antifreeze coolant is found to be less than the minimum scale value (the normal capacity of the antifreeze coolant should be between min and max), it should be increased in time, otherwise the cooling efficiency of the engine will be affected.

Here's how to replace it;

1. When replacing Corolla antifreeze, the first and most important step is to wait for the vehicle to cool down, and do not replace the antifreeze when the engine is at a high temperature. First, there will be a risk of burns, and secondly, the release of antifreeze during the "hot car" will also affect the cooling of the vehicle.

2. Half an hour after the hot car that Corolla has just driven off, the water temperature will drop significantly, and the work of replacing the antifreeze can be carried out at this time. The first step: drain the water, there are many ways to drain the water, the more standardized operation is to lift the car, unscrew the water drain screw at the bottom, and let the freeze before the reed sleepiness be discharged from the water drain screw hole.

There are certain hardware requirements for using this method, that is, a vehicle lift is required, and there is a disadvantage that the speed will be slower if the antifreeze is put with a water drain screw.

3. When filling with new antifreeze, you can directly pour about about (depending on the model) of antifreeze into the storage tank, and stop filling after the liquid level reaches the upper limit max position. At this time, unscrew the water drain screw next to the "water pipe", and continue to start filling antifreeze, see the antifreeze from the water discharge screw argument wire gushing out continuously and without bubbles, and then tighten the water drain screw, so far the first time to fill the antifreeze and release air The work is basically completed.

4. After starting the Corolla, idle for 3-5 minutes to let the vehicle enter the normal working temperature, and make the new antifreeze can be fully circulated in the waterway in the car, and then turn off the engine, open the liquid reservoir will find that the liquid level height has been reduced, then only need to add an appropriate amount of antifreeze to keep the liquid level between max and min.

The antifreeze replacement cycle is 100,000 km and the replacement capacity is 8L. The antifreeze reservoir of the Toyota Corolla is located on the left side of the engine. This is only a reference replacement cycle, the owner can replace it according to the actual use, because Chatan infiltration is not a big problem to go another 10,000 kilometers or extend the use cycle for about one and a half years.

If the vehicle is strong, it can be replaced before the call. However, during the period when the antifreeze coolant is not replaced, if it is found that the antifreeze coolant is less than the minimum scale value (the normal capacity of the antifreeze coolant should be between min and max), it should be increased in time, otherwise the cooling efficiency of the engine will be affected.

Toyota Corolla Antifreeze Replacement Tutorial:

1.First, let the vehicle stop for a while to cool down the high-temperature antifreeze that has just stopped circulating. Unscrew the drain valve at the bottom of the tank until the antifreeze is completely drained from the tank.

2.Hang the vehicle into neutral and pour clean water into the antifreeze storage tank to continuously flush the remaining antifreeze from the cooling system. When you see that the water discharged from the spout is almost colorless, it means that the old antifreeze has been almost completely removed.

3.When the water is no longer flowing out, close the drain valve and turn off the engine. At this point, add antifreeze to the reservoir and the level should be kept between max and min. It's okay to accidentally add extra antifreeze.

4.When the vehicle is ignited and idled, the air in the cooling system will be discharged and the antifreeze level will drop some distance.

5.Wait for a while, when the liquid level no longer changes, add antifreeze between min and max, and then complete the replacement of antifreeze.

1. First of all, park the vehicle for a period of time in order to cool the high-temperature antifreeze that has just stopped circulating. Unscrew the water valve at the bottom of the tank until the antifreeze is completely drained from it.

2. Hang the vehicle to run in neutral gear, and pour clean water into the storage tank of antifreeze at the same time, so that the clean water continuously flushes the residual antifreeze in the cooling system.

3. When the water flow is no longer flowing out, close the water drain valve tightly and turn off the engine. At this time, fill the reservoir with antifreeze, and keep the liquid level between max and min, if you accidentally add more, it doesn't matter.

4. Ignition the vehicle, under the idle condition, the air in the cooling system will be discharged, and the antifreeze level will be lowered by a certain distance.

5. Wait for a period of time, wait for the liquid level to no longer change, replenish the antifreeze between min and max, and complete the replacement of the antifreeze at this time.

Toyota Corolla has added a method for releasing antifreeze

1. The simplest way to talk about the monogram is to use a syringe and use a thin catheter to draw out the antifreeze.

2. The water drain screw is generally at the position of the water pipe of the cooling fan, and the excess liquid can be released by unscrewing it. (It is not recommended for car owners to try it themselves.) Because there is a certain pressure in the tank, the pressure relief process itself is also dangerous.

In addition, the location of some drain valves is not easy to find, and it is even more difficult to operate. )

Toyota's new Corolla antifreeze was replaced at 160,000 kilometers for the first time, and then every 80,000 kilometers. Replacement: The drain valve of the water tank has a white plastic column on the lower right side of the back of the water tank (not buried at the bottom), and the water from the tank can be discharged by removing it, do not remove the water tank cover when the engine is high, the high-pressure engine antifreeze will spray out of the water tank, which may cause serious burns.

It is strictly forbidden to open the water tank cover or drain valve when the antifreeze temperature is very high to avoid burns.

The capacity of the Corolla tank: the displacement of the manual version is liters, the CVT version is liters, and the capacity of the antifreeze reservoir of the interplex cooler in the middle bend is liters. The displacement of the manual version of the liters, the CVT version of the liters, and the displacement of the liters.

After the water tank is discharged, the water drain valve is installed, and a new antifreeze is filled at the antifreeze filling port in the engine compartment, and the antifreeze is added, and the diluted antifreeze concentrate and clean tap water are used to prepare a mixture of 1:1 ratio. The specific proportions are indicated in the purchased antifreeze tank.
