A liquid that removes excess heat from a running engine, protecting it from critical overheating, is called antifreeze. It prevents freezing of the cooling system in winter when the car is idle. During the operation of transport, the beneficial properties of antifreeze gradually evaporate, which forces it to be periodically replaced.

Cooler properties

During operation, the temperature of the coolant reaches, and sometimes exceeds, 100 degrees, and during idle time it is compared with the ambient temperature. The effective functionality of the Toyota Camry cooling system, as well as the durability of the V50 power unit, depend directly on the quality of antifreeze, which must meet the following requirements:

• mobility;
• high thermal conductivity, as well as heat capacity;
• small coefficient of crystallization and expansion temperature;
• the substance must have anti-corrosion properties and must not corrode rubber elements.

Cooler classification

There are three types of cooling fluids:

• basic;
• silicate-free;
• no nitrates.

Based on the basis of the substance, they are divided into propylene glycol and ethylene glycol. Each group has an individual set of additives and composition. Mixing different refrigerants is almost always prohibited. This is especially true of the silicate-free group, since the resulting solution can coagulate in the cooling system, clogging it. This will lead to the need for flushing.

Requirements are made for antifreeze, taking into account the individual characteristics of the cooling system. For the effective functionality of the Camry 2.4 engine, the manufacturer recommends the use of silicate-free solutions based on propylene glycol containing a corrosion inhibitor.

These requirements are put forward taking into account the functions of the cooling system: more viscous compositions are ideal in the process of forced injection of antifreeze. Taking into account such requirements, the most optimal for the Camry V50 will be the use of the following compounds:

• SuperLongLifeCoolant (S LLC) - pink;
• LongLifeCoolant (LLC) - red.
  

To avoid premature engine damage from overheating, you should not use antifreeze to cool it. This will not lead to good.

When a cooler replacement is required

The frequency of scheduled fluid changes depends on the service life indicated on the package. If, for any reason, Toyota Camry antifreeze leaves much faster, an early refill or replacement is carried out.

Signs of unsuitable coolant:

1. Formation of a jelly-like mass on the expansion tank.
2. With slight frosts, the substance takes on a mushy state or a precipitate forms.
3. The cooler fan operates more frequently than usual.
4. Liquid contamination is detected visually.
5. Forced need to top up the system with water.

Self replacement

Replacing antifreeze Toyota Camry V40 is not particularly difficult. First of all, it is necessary to install a pan under the engine and radiator, the spent mixture will drain into it. The drain cover on the radiator opens and the plug is twisted. Then you need to unscrew the drain plugs located on the radiator and cylinder block to allow the contents to drain completely. After that, all the plugs are tightened, and the applied antifreeze is poured in as much as is required up to the maximum mark. Typically, a Camry V50 can consume about 4.5-5 liters. This is considered the norm for this model.

When buying, you need to know the shade - Colour and Type of the correct antifreeze for the year of manufacture of your Camry Xv40. Select the manufacturer at your discretion. Do not forget - each type of fluid has its own service life.
For example: for Toyota Camry (Body Xv40) 2006 onwards, with a gasoline or diesel engine type, suitable - carboxylate class of antifreeze, type G12 + with shades of red. The approximate next replacement time is 5 years. If possible, check the selected fluid to meet the vehicle manufacturer's specifications and service intervals. It's important to know Each type of liquid has its own color. There are rare cases when a type is tinted with a different color.
The color of red antifreeze can be from purple to light pink (green and yellow have the same principles).
Mix liquid from different manufacturers - can if their types match the mixing conditions. G11 can be mixed with G11 analogues G11 cannot be mixed with G12 G11 can be mixed G12 + G11 can be mixed G12 ++ G11 can be mixed G13 G12 can be mixed with G12 analogues G12 cannot be mixed with G11 G12 can be mixed with G12 + G12 cannot be mixed with G12 ++ G12 cannot be mixed with G13 G12 +, G12 ++ and G13 can be mixed with each other Mixing of Antifreeze with Antifreeze is not allowed. No way! Antifreeze and Antifreeze are very different in quality. Antifreeze is the trade name of the traditional type (TL) of the old-style coolant. At the end of its service life, the liquid completely discolours or becomes very dull. Before changing one type of fluid to another, flush the car's radiator with plain water.

Antifreeze is an antifreeze process fluid designed to cool a working Toyota Camry engine at an external temperature from + 40C to -30..60C. The boiling point of antifreeze is about + 110C. The function of antifreeze also includes lubrication of the interior surfaces of the Toyota Camry system, including the water pump, to prevent the formation of corrosion. The life of the unit depends on the condition of the liquid.

Antifreezes are distinguished by the additives included in it:
Traditional antifreezes;
Hybrid antifreeze G-11 (Hybrid, "hybrid coolants", HOAT (Hybrid Organic Acid Technology));
Carboxylate antifreezes G-12, G-12 + ("Carboxylate coolants", OAT (Organic Acid Technology));
Lobrid antifreezes G-12 ++, G-13 ("Lobrid coolants" or "SOAT coolants").

Types and types of antifreeze for Toyota Camry

If you need to add coolant to your Toyota Camry, it is safe to mix only one type of antifreeze, not the color. Color is just a dye. It is forbidden to pour water (even distilled water) into the Toyota Camry radiator, since in the heat at a temperature of 100C the water will boil, and scale will form. In cold weather, the water will freeze, the pipes and the radiator of the Toyota Camry will simply burst.

Change the coolant for Toyota Camry for several reasons:

• The term of antifreeze ends - the concentration of inhibitors in it decreases, heat transfer decreases;
• The level of antifreeze from leaks has decreased - its level in the Toyota expansion tank should remain constant. In this case, it can go through leaks in the joints, or cracks in the radiator, pipes.
• The level of antifreeze has decreased due to engine overheating - the antifreeze begins to boil, a safety valve opens in the plug of the expansion tank of the Toyota Camry cooling system, dumping antifreeze vapors into the atmosphere.
• Toyota Camry cooling system parts are being replaced or the engine is being repaired;

A frequently triggered radiator fan in the heat is a reason to check the quality of antifreeze. If you do not timely replace the antifreeze with Toyota Camry, it will lose its properties. As a result, oxides are formed, there is a danger of engine overheating in hot weather and its defrosting at negative temperatures. The first replacement period for G-12 + antifreeze is 250,000 km, or 5 years.

Signs by which the condition of the spent antifreeze in Toyota Camry is determined:

• Test strip results;
• Measuring antifreeze in a Toyota Camry with a refractometer or hydrometer;
• Change in color shade: for example, it was green, became rusty or yellow, as well as turbidity, fading;
• The presence of shavings, chips, scale, foam.

Replacing antifreeze and coolant for Toyota Camry

Flushing the cooling system before pouring a new antifreeze on a Toyota Camry Flushing the Toyota Camry cooling system, before pouring a new antifreeze, completely removes the protective layer and remnants of the old antifreeze, this is necessary when changing from one type to another. To flush the Toyota Camry radiator, you should use a special agent, which is often diluted with water in accordance with the instructions.

The finished flush is poured into the expansion tank of the Toyota Camry radiator with the engine shut off. It must first be warmed up to operating temperature so that the thermostat opens and antifreeze begins to circulate in a large circle of the cooling system.

Then the engine is started, it is allowed to idle for 30 minutes. Discard the flushing liquid. The operation is repeated depending on the composition of the outflowing liquid. The flushing mixture can be used only in the first run, and in the following - distilled water. Antifreeze replacement time for Toyota Camry is from half an hour, with flushing - up to 1.5 hours.

Many drivers are wondering about the choice of quality antifreeze for their car.

A wide range of coolants in the car market will make even an experienced driver get confused, but choosing antifreeze is not difficult.

Types of antifreeze: what to pour into the Toyota Camry 40?

Antifreezes are classified by type, depending on the composition of the product, which determines the nature of its use. The following types of coolants are classified:

• Traditional - contain a minimum amount of additives;
• Hybrid G-11 - is a basic set of inorganic components, suitable for occasional or sparing use of the car;
• Carboxylated G12 or G12 plus - formulations designed for modern and high-revving engines, ideal for the Camry engine;
• Lobrid antifreezes G12 ++ or G13 are the most environmentally friendly and contain a lot of additional additives. Suitable for Camry, but have a high cost.

Do not pour distilled or purified water into Toyota Capri - this can lead to engine boiling or metal oxidation and chipping. Protect your car - only use certified products!

It's important to know! You can mix only one type of antifreeze, which is characterized by the composition of the product. The same color in coolants is not an indication of product compatibility.

When should the coolant be changed?

The amount and quality of antifreeze are characteristics that affect the technical condition of a vehicle engine. It is important to monitor the level and condition of antifreeze in order to make adjustments in a timely manner. Replacing the coolant is required in the following cases:

• The presence of metal shavings or dirt in the liquid;
• The appearance of turbidity or sediment formation;
• The appearance of chips or scale inside the motor space;
• During technical examination with a refractometer;
• With appropriate results on the test strip.

It is also required to change the coolant after an engine overhaul or the expiration date of the antifreeze. It is recommended to change antifreeze every five years or when passing 250 thousand kilometers.

Replacing antifreeze - we carry out the procedure correctly!

Filling with coolant is a normal situation, as a result of which there is no particular difficulty or the need to use special tools. In order to properly carry out the procedure for replacing antifreeze, it is recommended to adhere to the following instructions:

More detailed information on the procedure for replacing the coolant can be obtained by watching the accompanying video on the website.

Secrets and life hacks: extending the life of your car

It is necessary to fill in antifreeze only in a muffled engine. It is also recommended to let the engine cool down to the optimum temperature - opening the valve on the expansion tank when the engine is hot can cause a pressure breakdown, as a result of which the heated liquid will scald. It is necessary to open all drain plugs on the crankcase very carefully and slowly, gradually relieving internal pressure.

Note! Before pouring a new type of antifreeze, it is necessary to completely drain the old one and flush the car engine. This procedure will remove the remnants of the old antifreeze and remove the protective oxidizing layer on the metal surface.

It is necessary to fill the flush into the engine warmed up to operating temperature, so that the thermostat opens in the system, and the flush begins to circulate through the cooling system. Due to the engine capacity of 2.4 liters, the flushing fluid will require about 7-8 liters.

Remember, timely replacement of antifreeze will significantly extend the life of the engine. Regular diagnostic checks and careful car care will ensure a long and comfortable operation of the Toyota Camry. Protect your vehicle from breakdowns and overloads!
