Replacing the coolant (hereinafter referred to as the coolant) in any car is an important part of the technical work. Therefore, special attention should be paid to the choice of antifreeze, in particular when it comes to Nissan cars. Today you will learn how to replace Nissan Almera Classic antifreeze, what is needed for this and what refrigerant is best to fill.

Getting ready for replacement

Replacing consumables includes not only the direct process of technical work, but also preparation. When preparing to change the coolant, you need to know which fluid is best to fill, how much of it is needed, and you also need to prepare everything that may be useful in the process.

What kind of coolant should I use?

If you do not know what antifreeze you should use in your car, then read the information provided below. For Nissan Almera Classic cars, as for any other foreign car, it is recommended to use only high-quality antifreeze. The use of refrigerants based on ethylene glycol is allowed; as a rule, the brand of coolant is indicated in the instructions for the vehicle.

The manufacturer recommends filling your vehicles with original Nissan L250 refrigerant. As you know, this consumable material fully meets the requirements of the cooling systems of Nissan Almera Classic cars. Its reliability and performance largely depend on the cooling of the machine’s power unit, so the choice of coolant should be approached very carefully and responsibly. Nissan L250 helps prevent corrosion on the internal walls of cooling system components, as well as leaks and boiling of consumables.

The fluid has been produced in accordance with international standards and is able to ensure a long service life of the cooling system of your Nissan. The color of the original products is green, but this does not affect the characteristics of the refrigerant.

If you are not able to purchase the original product in your city, then contact the dealer or order it online. If you cannot do this for some reason, then select analog products that meet the specifications of your car.

Note! Today there are many types of coolants on the domestic car market, but not all of them meet the requirements of Nissan Almera. Refrain from purchasing if you are not sure that this is an original product.

We are replacing

The manufacturer recommends replacing consumables every 60 thousand kilometers or once a year, whichever comes first. The first coolant replacement should be done after 90 thousand km. It is strictly not recommended to use coolant after this period, since the substance loses its properties and is not able to fully cool the engine.

What will you need?

You will need:

new Nissan L250 antifreeze in the amount of 7 liters (the system holds 6.7 liters);
containers for collecting waste consumables;
7 liters of distilled water;
set of wrenches;
adhesive sealant;
rags.

Instructions

We will consider the process of completely replacing the coolant, that is, flushing the cooling system.

So, drive your car into a garage with a pit or onto a lift.
Reach under the bottom and use a wrench to unscrew the bolts securing the engine protection.
You will see a radiator from which you need to disconnect the lower pipe. Having done this, unscrew the radiator cap, placing a container under it in advance to collect waste consumables.
Unscrew the drain plugs on the engine cylinder block. Wait about 15-20 minutes until the fluid drains from the system.
You also need to disconnect and drain the coolant from the expansion tank - some amount of old antifreeze remains in it, but since we are completely replacing the substance, the coolant needs to be drained from the tank.
Let's start flushing the system. Take distilled water and start pouring it into the radiator. Pour until it begins to come out of the bypass plug, then tighten it further. The expansion tank should also be filled with water. After this, screw the cap on the radiator.
Turn on the engine and let it idle until the engine warms up to operating temperature.
Press the accelerator pedal several times and then turn off the engine. Wait until it cools down and repeat the coolant drain procedure.
Replace the expansion tank and tighten all caps on the engine cylinder block and radiator. Before tightening the cylinder block cover, lubricate the hole with sealing glue.
Remove the bypass plug.
Take new original antifreeze and fill it into the radiator and expansion tank to the required level. Consumables should be poured very slowly. This must be done in order to prevent air locks from appearing in the system. If you add liquid slowly, the air will have time to escape from the system.
When refrigerant begins to come out of the bypass plug, tighten it.
Remove the radiator cap and start the engine to idle. Run the engine at a speed of at least 3 thousand per minute for 10 seconds. After this, slow down and tighten the cap on the radiator.
This procedure should be repeated several times, but make sure that the motor does not overheat.
Turn off the car and wait until the engine cools down to 40-50 degrees. You can turn on the fan to help it cool down faster.
Now check the level of consumables in the expansion tank and, if necessary, add to the radiator up to the neck.
Add coolant to the expansion tank up to the MAX mark.
Then start the engine again, crawl under the bottom and check the system for leaks. If they occur, then they can be identified quickly, because this is why the coolant is painted in different colors.

Refill containers.

Checking the coolant level.

Make sure the coolant level in the reservoir is between the MIN and MAX marks when the engine is cold.

If there is less or more coolant, bring the level up to normal!

Coolant drain.

1. Remove the lower engine protection.

2. Disconnect the lower hose from the radiator and remove the radiator cap.

3. Remove the drain plugs from the drain holes on the cylinder block.

4. Remove the reservoir and drain the coolant.

Check the coolant for contaminants such as rust, corrosion or discoloration. If there are traces of contamination, flush the engine cooling system.

Flushing the cooling system.

1. Fill the radiator with water until water flows out of the bypass plug, then tighten the plug.

3. Start the engine and warm it up to normal operating temperature.

4. Press the accelerator pedal two or three times without load.

5. Stop the engine and wait until it cools down.

6. Drain the water.

Filling the engine with coolant.

1. Install the tank, screw the plugs into the drain holes on the radiator and cylinder block.

2. Apply sealant to the threads of the cylinder block drain plug.

3. Use branded sealant or equivalent.

4. Remove the bypass plug.

5. Fill the radiator and reservoir to the required level. Add coolant slowly at a rate of less than 2 liters. per minute so as to allow air to escape from the system.

6. Tighten the bypass plug when coolant begins to flow out.

7. Start the engine and warm it up to normal operating temperature by removing the radiator cap. If coolant is pouring out of the radiator filler neck, replace the cap.

Run the engine at 3000 rpm for 10 seconds, then return to idle speed with the radiator cap on.

8. Repeat two to three times.

ATTENTION! Monitor the coolant temperature gauge so as not to overheat the engine.

9.Stop the engine and cool to below 50°C. Use a fan to cool to save time.

If necessary, fill the radiator with coolant up to the filler neck.

11. Check the cooling system for leaks with the engine running.

12. Warm up the engine and check the sound of coolant leaking by increasing the engine speed from idle to 3000 rpm and setting the heater temperature control to several positions between COOL and WARM.

The optimal temperature of an internal combustion engine is between 80-90 degrees Celsius. To maintain this mode, it is necessary to constantly remove heat from heated parts. All modern cars are 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 gone through a full heat exchange cycle.

What is coolant (antifreeze) used for?

Previously, many car owners used ordinary water instead of antifreeze. Such actions were erroneous, since water has a low boiling point, as a result of which scale forms on the internal 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. The first antifreeze replacement in 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 Nissan antifreeze (ethylene glycol based), which is indicated in the documentation for the 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:

Unscrewing the tap on the radiator, which is accompanied by leakage of antifreeze.
Removing the radiator cap. After this, you will find that the liquid will begin to pour out more intensely.
Removing the expansion tank cap.
Unscrewing the plug on the cylinder block.
Tightening the plug on the cylinder block.
Turning the tap on the radiator.
Filling the cooling system with antifreeze.
Fill the expansion tank with antifreeze to the appropriate mark.
Tightening the radiator cap and expansion tank.
Engine starting. During its operation, we monitor the readings of the temperature sensor in the cooling system.
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.

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 requirements of the vehicle manufacturer's specifications and maintenance intervals. It is 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 (green and yellow have the same principles).
Mix liquid from 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. No way! 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
