Many owners know that replacing Nissan Almera Classic antifreeze is one of the preventive maintenance works on the car. It is very important and must be performed according to all the rules so as not to aggravate the situation. Nissan Almera N16, G15.

What coolant to use

For all foreign cars, including these, you need to use only quality liquid. However, the use of refrigerants based on ethylene glycol is allowed. The specific required brand of coolant should be written in the instructions for your device.

The creators of the Almera 2014 car advise which antifreeze to use, and this is the Nissan L250. This is an original refrigerant that meets all international requirements and ensures long-term operation of your cooling system. This liquid is green in color, although this factor does not affect any of its characteristics.

Try to find exactly this type of product. If the coolant you need is not available where you live, you can order it online or from a dealer. But if you still cannot do this, then try to choose a similar product.

There are many videos talking about coolant. But not all consumables meet the requirements for this machine. Buy only the original, and if you are not sure, then do not make a blind purchase.

Fluid replacement

Car developers advise changing it every 60,000 km or once a year. But the very first coolant replacement should be done after the first 90,000 km. The coolant cannot be used after this period in Nissan, since the liquid no longer has the necessary properties and cannot sufficiently provide the required engine cooling.

Tools:

1. 7 liters of new Nissan L250 fluid. In total it holds 6.7 liters.
2. A container for collecting unnecessary antifreeze.
3. Distilled water, you need 7 liters.
4. Wrenches.
5. Adhesive sealant.
6. Rags.

Procedure:

1. Before starting, it’s worth clarifying what it is complete replacement coolant with the included flushing of the cooling system.
2. Place the car on a pit or on a lift.
3. Get under the bottom of the car. Using a wrench, unscrew all the bolts that secure the protection to the engine.
4. There will be a radiator there. Disconnect the lower pipe from it. Place a container under the radiator to collect the old substance and unscrew the cap of the radiator itself.
5. Find and unscrew the drain plugs in the engine cylinder block. Wait until all the liquid has drained out, this takes 15–20 minutes.
6. The refrigerant on the expansion tank must be disconnected in order to drain the substance afterwards. Since this is a complete replacement of the fluid, the remaining antifreeze must be poured out of the reservoir.
7. We begin flushing the system. Start pouring distilled water into the radiator. Fill it until it goes beyond the bypass plug, and then tighten it as tightly as possible. Fill with this water expansion tank. Then return the radiator cap to its place and tighten it.
8. Activate the engine. Let it idle to warm up the engine to operating temperature.
9. Press the accelerometer pedal 2–5 times, then turn off the engine. Wait for it to cool and repeat the draining process.
10. Install the expansion tank in its place. Close the engine and radiator cylinder block with the cover. Using sealing adhesive, lubricate the hole until the block cover closes.
11. Carefully remove the bypass plug.
12. Take new fluid, pour it into the radiator, then into the expansion tank. The pouring process should be done slowly. This is done so that air does not get into where we are pouring. This means that the air must have time to leave that place so that an air lock does not form.
13. When refrigerant leaks out of this bypass plug, it must be tightened faster.
14. Remove the radiator cap, then start the engine so that it runs at idling(rpm 3000 for 10 seconds). Next, reduce the speed and close the radiator with a cap.
15. Then repeat these steps several times. Monitor the engine to avoid overheating.
16. Turn off the engine and wait until it cools down to about 40–50 degrees. A fan can help in this matter.
17. Check the amount of liquid in the expansion tank, top up to the throat if necessary.
18. Add fluid to the expansion tank to the MAX mark.
19. Turn on the engine. Get under the car and inspect the entire system for leaks.

If they do appear, they are easy to find; this is why the liquid is painted in different colors.

Conclusion

Coolant plays an important role. The reliability and ability to operate the entire Almera machine depends on it. That is why it is worth choosing high-quality and original coolant. This is the Nissan L250. It prevents corrosion inside the cooling system, boiling, and leakage of substances. Remember that replacing antifreeze on a Nissan Almera Classic car is a simple but regular action that you will have to do so that your car can live.

Antifreeze for Nissan Almera G15

When purchasing, you need to know the shade - Color And Type antifreeze allowed for the year of manufacture of your Almera G15. Select the manufacturer at your discretion. Do not forget - each type of liquid has its own service life.
For example: for Nissan Almera (G15 body) 2012, with a gasoline or diesel engine, suitable - lobrid antifreeze class, type G12++ with shades of red. The approximate time for the next replacement will be 7 years. If possible, check the selected fluid for compliance with the vehicle manufacturer's specifications and maintenance intervals. Important to know Each type of liquid has its own color. There are rare cases when the type is tinted with a different color.
The color of red antifreeze can be from purple to light pink (for green and yellow too principles).
Mix liquid different manufacturers — Can, if their types meet 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 Antifreeze with Antifreeze is not allowed. Under no circumstances! Antifreeze and Antifreeze differ greatly in quality. Antifreeze is the trade name for the traditional type (TL) of old-style coolant. At the end of its service life, the liquid becomes completely discolored or becomes very dull. Before replacing one type of fluid with another, rinse the car radiator with plain water. . Additionally

Antifreeze is a brand of domestic antifreeze, developed back in 1971, which began to be produced in Togliatti during the Soviet era. There were only 2 types of domestic antifreeze: antifreeze-40 (blue) and antifreeze-65 (red).

Antifreezes are distinguished by the additives they contain:

• 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 antifreeze G-12++, G-13(“Lobrid coolants” or “SOAT coolants”).

Coolant is replaced on Nissan Almera for several reasons:

• Antifreeze is running out- the concentration of inhibitors in it decreases, heat transfer decreases;
• The level of antifreeze from leaks has decreased- its level in the Nissan expansion tank must remain constant. In this case, it can escape through leaks in connections, or cracks in the radiator or pipes.
• Antifreeze level decreased due to engine overheating- the antifreeze begins to boil, a safety valve opens in the expansion tank cap of the Nissan Almera cooling system, releasing antifreeze vapors into the atmosphere.
• Nissan Almera cooling system parts are being replaced or engine repair;

Signs by which the condition of used antifreeze in Nissan Almera is determined:

• Test strip results;
• Measuring antifreeze in Nissan Almera with a refractometer or hydrometer;
• Change color shade: for example, it was green, it became rusty or yellow, as well as cloudiness, fading;
• Presence of chips, chips, scale, foam.

The finished flush is poured into the expansion tank of the Nissan Almera radiator with the engine turned off. It must first be warmed up to operating temperature so that the thermostat opens and antifreeze begins to circulate through the big circle cooling systems.

Then start the engine and let it idle for 30 minutes. Drain the flushing liquid. The operation is repeated depending on the composition of the leaking liquid. The washing mixture can only be used on the first pass; in subsequent runs, distilled water can be used. The time for replacing antifreeze on a Nissan Almera is from half an hour, with flushing – up to 1.5 hours.

Reasons and signs for an immediate coolant change in the Nissan Almera G15

REFERENCE. Antifreeze is a car's coolant. The combustion of the fuel mixture occurs at temperatures above 2000 degrees, so antifreeze is simply necessary for the correct operation of the engine.

The main causes of fluid malfunction:

1. Antifreeze has lost its properties, accompanied by low heat transfer and the creation of corrosion.
2. Incorrect concentration of antifreeze and water. When mixing them, problems often occur in the engine cooling system. Thus, you need to look at the brands of chemicals used. If you do not solve the problem for a long time, the hoses become dirty and the car’s thermostats fail.

There are several symptoms that indicate a malfunctioning coolant:

1. The appearance of sediment on the expansion tank of the car. This is a clear sign of inoperability.
2. Increase in freezing temperature. Our specialists will help you measure the indicator using special instruments.
3. Brown color of a cooling chemical. As a rule, it indicates corrosive effects.

Optimal engine temperature internal combustion is between 80-90 degrees Celsius. To maintain this mode, it is necessary to constantly remove heat from heated parts. All modern cars equipped with a liquid cooling system, which includes:

• main radiator,
• radiator for oil cooling,
• forced cooling fan,
• pump for pumping liquid,
• thermostat,
• expansion tank,
• connecting pipes,
• temperature sensor.

Also in the cylinder block and its head there are special holes through which coolant circulates.

There are two antifreeze circulation circles: small and large. The first is designed to quickly heat the engine and coolant. The second is necessary for cooling the antifreeze after it has passed through full cycle heat exchange.

What is coolant (antifreeze) used for?

Previously, many car owners used ordinary water instead of antifreeze. Such actions were erroneous, since water has low temperature boiling, as a result of which scale forms on the inner walls of the cooling system elements. This leads to deterioration of heat transfer and, as a result, rapid wear of motor parts. To avoid such a development of events, it is necessary to use a special coolant.

Timing for replacing Nissan antifreeze

Many car owners neglect the timely procedure for replacing antifreeze, but in vain, because... The performance of the car engine depends on this, as you saw earlier. First antifreeze change Nissan cars should be carried out after 90 thousand mileage, and each subsequent one - every 60 thousand. If you postpone this procedure for the future, you may encounter the fact that the coolant will begin to change its properties and negatively affect the metal (usually aluminum) from which the cylinder head and the block itself are made.

Instructions for replacing antifreeze in Nissan cars

For this brand of car it is recommended to use original antifreeze Nissan (ethylene glycol based), which is specified in the documentation for vehicle. If it is not possible to use the original coolant, select an analogue based on the fluid specifications.

Never begin replacement when the engine is hot, otherwise you may suffer serious burns.
Also, use gloves.

The coolant replacement process is as follows:

1. Unscrewing the tap on the radiator, which is accompanied by leakage of antifreeze.
2. Removing the radiator cap. After this, you will find that the liquid will begin to pour out more intensely.
3. Removing the expansion tank cap.
4. Unscrewing the plug on the cylinder block.
5. Tightening the plug on the cylinder block.
6. Turning the tap on the radiator.
7. Filling the cooling system with antifreeze.
8. Fill the expansion tank with antifreeze to the appropriate mark.
9. Tightening the radiator cap and expansion tank.
10. Starting the engine. During its operation, we monitor the readings of the temperature sensor in the cooling system.
11. We turn off the engine and look at the fluid level indicator. The level should be between the MIN and MAX marks.

• In order to empty the expansion tank, you need to remove it. This is done easily: take a suitable key and unscrew the bolt that holds the tank. After removing the liquid, disconnect the hose and thoroughly rinse the tank and then dry it.
• As a rule, after draining the antifreeze, there is still some liquid left in the system. Blow into the filler hole to expel all the coolant.
• After replacing the antifreeze, it is recommended to drive the car a couple of tens of kilometers, and then add the required amount of fluid.
• Before adding new antifreeze, you can rinse the system with plain water, or use special compounds.
• Under normal conditions, the boiling point of antifreeze is 108 degrees Celsius, in a sealed cooling system 130 degrees Celsius. Therefore, if the seal is broken (for example, a crack has formed in the expansion tank or hose), the engine will boil. To avoid this, change the expansion tank and hose in a timely manner.

If you doubt that you can carry out the antifreeze replacement procedure yourself, then contact a specialized Nissan car service center, where experienced and professional mechanics will solve this problem for you.
