How to replace antifreeze on a Toyota Avensis?

The cooling system of a Toyota Avensis brand car, like all cars, is responsible for storing, circulating, and also supplying antifreeze to the car's power unit. Due to the fact that the presented system is working, the car engine is protected from overheating and boiling. Timely replacement of the coolant is extremely important, as this ensures the normal operation of the vehicle's power unit. Also, due to the fact that the cooling system is working properly, the car engine is protected from premature wear and corrosion.

According to the instructions on the Toyota Avensis, antifreeze must be changed after the car has reached 40 thousand kilometers. Although it should be noted that experts in the field of automotive technology recommend carrying out the indicated procedure annually, regardless of how many kilometers the car has driven. This rule is especially true for cars with an aluminum radiator. The better the antifreeze that the car owner poured into the expansion tank, the less likely it is that corrosion will form in the car's cooling system. In addition, it should be noted that a coolant has recently appeared on the automotive market, which, according to experts, is able to retain its properties for a long time. Using the prescribed antifreeze, a vehicle can travel up to 100 thousand kilometers without replacement.

The procedure for replacing coolant in a Toyota Avensis is not complicated. Based on this, the owner of the vehicle can cope with the presented task on their own, without resorting to the help of specialists. However, it should be noted that in this case, a certain procedure must be followed, which will be presented below. First you need to drain the coolant, flush the cooling system and finally fill in fresh antifreeze. Also in the content of the current article, information will be provided on how to choose the necessary antifreeze.

The process of replacing antifreeze on a Toyota Avensis

Before proceeding with the process of replacing the antifreeze in the provided vehicle, the motorist must prepare the following tools:

• Ten liters of new coolant suitable for a Toyota Avensis car;
• A container into which the old coolant will merge;
• A set of keys;
• Rags.

The manufacturer of the Toyota Avensis brand car recommends that the first replacement of antifreeze be carried out after the car has traveled 160 thousand kilometers. Subsequent coolant changes are required after the car has traveled 80 thousand kilometers. However, it should be borne in mind that in practice the work presented is recommended to be carried out more often, that is, once every 40 thousand kilometers, if the state of the antifreeze deteriorates (color change, precipitation or a reddish tint) a black tint appears).

When choosing the necessary coolant, the owner of a Toyota Avensis car must take into account the year of manufacture of the car. According to the test results of the Toyota Avensis car, experts came to the conclusion that there is a certain list of antifreezes recommended for use in this car.

Refrigerant to be purchased for Toyota Avensis:

• For cars manufactured in 1997, G11 class coolant is suitable, the color of which is green. The best brands of the presented machine are: Aral Extra, Genantin Super and G-Energy NF;
• If a Toyota Avensis car rolled off the assembly line between 1998 and 2002, a motorist is advised to purchase G12 class antifreeze. The best options for this car are the following: Lukoil Ultra, MOTUL Ultra, AWM, Castrol SF;
• Coolant replacement in Toyota Avensis vehicles manufactured from 2003 to 2009 is carried out with G12 + class coolant, the color of which is red. In the presented case, the car owner is recommended to purchase antifreeze of the following brands: Lukoil Ultra, G-Energy, Havoline, Freecor;
• When replacing the coolant in a Toyota Avensis car that rolled off the assembly line after 2010, G12 ++ class red antifreeze is used. Popular products in this situation are Frostchutzmittel, Freecor QR, Castrol Radicool Si OAT, etc.

It should also be noted that when buying antifreeze, the owner of Toyota Avensis should pay attention to the volume of coolant. The required amount of refrigerant can be from 5,8 to 6,3 liters. It depends on which gearbox and powertrain are installed on the car. Based on the information provided, it is recommended to immediately purchase a 10-liter can of antifreeze.

In addition, attention must be paid to the possibility of mixing refrigerants from different manufacturers. However, this can only be done if their types match the merge conditions.

What antifreezes can be mixed for a Toyota Avensis car will be shown below:

• G11 can be mixed with G11 analogues;
• G11 must not be mixed with G12;
• G11 can be mixed with G12+;
• G11 can be mixed with G12++;
• G11 can be mixed with G13;
• G12 can be mixed with G12 analogues;
• G12 must not be mixed with G11;
• G12 can be mixed with G12+;
• G12 must not be mixed with G12++;
• G12 must not be mixed with G13;
• G12+, G12++ and G13 can be mixed with each other;

It is also required to take into account that mixing antifreeze (traditional class coolant, type TL) with antifreeze is not allowed. The presented action is not possible under any circumstances.

Draining the old coolant and flushing the Toyota Avensis system

Before proceeding with the procedure for replacing automatic transmission antifreeze in a Toyota Avensis car, the car owner must let the power unit cool down. It is also necessary to take into account that you should immediately decide on a place to perform the presented work - the site should be as flat as possible. The best solution would be to replace the antifreeze in a flyover or pit. In addition, it should be noted that the vehicle must be insured.

After completing the above steps, the owner of a Toyota Avensis brand car can begin to drain the old antifreeze:

• To begin with, the motorist must displace the plug of the expansion tank of the Toyota Avensis car. This is done to relieve pressure in the cooling system. Turn the cap counterclockwise. It should also be noted that you need to proceed carefully and, if necessary, use a clean rag as a pad. Rushing to unscrew this cover may cause the car owner to burn his hands or face;
• At the next stage, it is required to substitute an empty container under the place where the spent antifreeze will merge;
• The old coolant is then drained from the car's radiator. There are two ways to carry out the presented action: unscrew the drain valve, which is installed in the lower tank, or throw out the lower pipe. In the case of using the first case, the owner of a Toyota Avensis brand car is recommended to use a rubber tube. This is done to prevent splashing;
• After that, it is necessary to drain the antifreeze from the power unit (cylinder block) of the Toyota Avensis car. To carry out the presented action, manufacturers also provide a drain plug that must be unscrewed;
• In conclusion, the vehicle owner can only wait until all the coolant has left the car's cylinder block.

The next step in replacing the coolant depends on the condition of the antifreeze. If the coolant has turned dark brown or contains residue, it is recommended to flush the entire cooling system. The mandatory performance of the presented work is carried out in a situation where antifreeze does not come out of the cooling system of a Toyota Avensis car or its color changes during the replacement process. With the help of flushing, a car enthusiast can achieve the removal of all dirt from the car’s cooling system, and it can also be used to remove all traces of used antifreeze.

To flush the cooling system of a Toyota Avensis car, a motorist needs to do the following:

• To begin with, the owner of the presented car must pour distilled water into the car's cooling system. It should also be noted that a motorist can use a special cleaning agent to clean this system. Washing material is poured according to the standard;
• When performing the above action, the owner of a Toyota Avensis car must make sure that all pipes, as well as filler and drain plugs, are properly closed;
• Next, the motorist must turn on the power unit of the Toyota Avensis car, and then carry out a control trip;
• The next step is to drain the flush material from the car's cooling system. The specified action is performed in accordance with the procedure indicated above. If distilled water or a special cleaning solution is too dirty, the vehicle owner must repeat the steps above. The lines must be flushed until the coolant flowing from the cooling system becomes completely transparent;
• After a car enthusiast who owns a Toyota Avensis car has bled the system, he must connect all the pipes in place. The presented action is performed in reverse order. After installing the thermostat. If the sealing rubber cannot be used further, the vehicle owner must replace it. It should also be noted that when connecting nozzles to the main pump, it is required to clean them from existing deposits. Also, if the antifreeze temperature regulator does not work, it should also be replaced with a new one. Clamps are installed and tightened to their original places. The installation of the bracket and drive belt with the power steering pump device is carried out after filling in new coolant.

Filling antifreeze in Toyota Avensis

After the owner of a Toyota Avensis car has completed the steps to drain the old antifreeze and flush the car's cooling system, he can proceed to the next step to replace the coolant, that is, fill in new antifreeze.

The procedure for pouring coolant into a Toyota Avensis car:

• You must first tighten all drain plugs;
• After that, you need to add new antifreeze. You can perform the presented action through the neck of the car radiator or the tank of the Toyota Avensis cooling system;
• Next, the car owner needs to turn on the power unit of the car, and then let it run for 7-10 minutes. At the right time, excess air in the Toyota Avensis cooling system must be removed through the antifreeze filler neck;
• The coolant level should be dropping. The motorist must monitor this process and recharge in a timely manner. This is done until the level of antifreeze rises to the required level (it is indicated on the expansion tank). In addition, it should be noted that recharging must be done on a cooled down engine of a Toyota Avensis car;
• Finally, check your cooling systems for leaks. If they are, they should be removed.

Recommendations that a motorist should consider when replacing antifreeze in a Toyota Avensis car:

• When flushing the cooling system, the vehicle owner is advised to use special or distilled products;
• Also, the finished washer fluid must be poured into the radiator reservoir with the car engine turned off. After filling the system with a special agent or distilled water, the power unit of the machine must be turned on and allowed to run for 20-30 minutes. This process can be repeated several times until clean flushing material exits the cooling system;
• It is recommended to use only high quality ethylene glycol based coolant. If the owner of a Toyota Avensis brand decides to mix antifreeze, he must first read the manufacturer's instructions. The volume of ethylene glycol in the composition should be in the range from 50 to 70 percent;
• 3-4 days after replacing the antifreeze, the driver is advised to check its level and top up if necessary.

Replacing antifreeze in other Toyota models

The process of replacing antifreeze in other Toyota models, such as: Karina, Passo, Estima, Hayes, does not differ from the previous procedure. The car enthusiast must also pre-prepare the necessary tools, as well as new coolant. After the vehicle owner needs to drain the old antifreeze, flush the cooling system and fill in new coolant. The only difference is the purchase of antifreeze. Each Toyota model has its own brand of coolant. Based on this information, before buying antifreeze, a motorist should either consult a specialist on this issue, or read the car's operating instructions on their own, which contains all the necessary information in detail.

Antifreeze replacement in a Toyota Avensis car or its other models is carried out for the following reasons:

• The service life of the coolant is coming to an end: the concentration of inhibitors in the coolant decreases, which leads to a decrease in heat transfer;
• Low antifreeze level due to leaks: The coolant level in the expansion tank of Toyota Avensis or other models should remain constant. It can flow through cracks in pipes or in a radiator, as well as through leaky joints;
• The coolant level has dropped due to overheating of the car's power unit; in the case presented, the antifreeze boils, as a result of which the safety valve opens in the cap of the expansion tank of the cooling system of a Toyota Avensis car or its other models, after which antifreeze vapors are released into the atmosphere;
• If the owner of a Toyota Avensis or its other model replaces parts of the system or repairs the car engine.

Signs by which the vehicle owner can determine the condition of used antifreeze in Toyota Avensis or its other models:

• Test strip results;
• Measure the coolant with a hydrometer or refractometer;
• If the color of the antifreeze has changed: for example, it was green, turned rusty or yellow, and also if it became cloudy or changed color;
• The presence of chips, chips, foam, scale.

If, according to the above signs, the motorist has determined that the antifreeze is in the wrong state, then the coolant must be replaced immediately.
