Correct replacement of antifreeze Renault Logan 1.6 8 valves

This text was written mainly for Renault Logan car owners and I hope it will become an excellent assistant who will teach you how to replace antifreeze in a car in just a few minutes.

This method is also suitable for other cars, but I wrote specifically for Renault Logan and was guided by the handling of this particular car. I also tested the method of replacing antifreeze in one of the Renault Logan cars presented to me.

In addition, I have extensive driving experience (I have been driving for more than five years) and I think that I will certainly be able to help you, as well as be useful in giving advice. I specialize mainly in cars and SUVs.

Precautionary measures

First, you should pay attention! If you are doing such work on your car, you should follow standard safety standards: before starting work on replacing antifreeze, wait a certain time.

Before the replacement itself begins, you should wait for the engine in the Logan car to cool down generally and wait until the liquid in its cooling system cools down.

Since during its operation, the engine temperature increases to more than 100 degrees. When working with the coolant mixture, try to use special protective gloves, since their durable base and chemical composition will protect you from antifreeze.

Gloves will also protect your skin from the harmful effects of chemical additives on your hands when drops of antifreeze get on your hands. Before you start replacing the fluid in Logan, you should lower the pressure in the engine cooling system itself .

Leaks and problems

There can be many reasons why antifreeze leaves, so in each specific case you need to immediately look for the cause, and then think about how to eliminate it. For example, if the interior smells of antifreeze, then there is a high probability that there is a problem with the stove or its pipes.

In general, when changing the coolant, you should carefully inspect all hoses and pipes for cracking, so that if something happens, replace them immediately. It is also worth paying attention to the thermostat, because most problems with poor heating lie there.

Users also note problems with the expansion tank. The plastic inside, which becomes brittle over time, breaks off and gets into the cooling system. Most often, the stove becomes clogged with these debris. Therefore, if a problem is detected, it is recommended to replace the tank immediately.

When to replace antifreeze

I would recommend pouring only new types of antifreeze into the Logan series G13 and later, since all new types of antifreeze have excellent characteristics for engine operation and were able to show themselves at the highest level in any weather. In addition, modern types of antifreeze of the G13 series are perfect for the 8-valve Logan, take this into account when choosing a mixture.

The composition of the cooling mixture for Renault Logan is usually yellow or red, and you should also take into account that the shade of the liquid cannot affect its performance during operation.

Why is it important to change the coolant?

Automotive fluids contain not only mixtures of ethylene glycol and monohydric alcohols, but also anti-corrosion additives. Depending on the type of corrosion inhibitors, coolants are divided into:

• G-11 – based on silicate or nitrite additives.
• G-12, G-12 – based on carboxylic acids.
• G-12 – includes organics and mineral inhibitors.

Mixing all types is not recommended, although the first two are, in principle, allowed. However, it should be taken into account that the service life of the coolant in this case is reduced. Why all these subtleties? The fact is that over time, the properties of chemical additives are lost, and ethylene glycol paired with water begins its corrosive activity. This threatens:

• Possibility of thermostat jamming due to the presence of corrosion products.
• Destruction of the water pump impeller.
• Depressurization of pump bearings.
• Clogged radiator and internal combustion engine channels.

All of the above factors will certainly lead to overheating of the engine, resulting in excessive fuel consumption and a decrease in power. Regular overheating reduces the operational life of the power unit several times.

Such consequences can be avoided by timely replacement of the antifreeze that has expired in full with Renault Logan. In addition, it is important to monitor its condition by periodically looking into the expansion tank.

Choosing antifreeze

If you are involved in car maintenance, then like any other engine, the Logan 8-valve version requires the closest attention.

Under the hood of an 8-liter Renault Logan, old antifreeze is poured, and you should take into account that the consistency of changing the cooling mixture to a new one will greatly depend on the operating conditions of the engine and the time of its operation.

That is why, if the car, for example, is usually operated in difficult weather conditions in the cold or hot, and also if you often drive the car in rainy weather, then replacement should be carried out more often than the time specified by the manufacturer.

Also, if you decide to get 100% return from cooling your Renault Logan car, then you should strictly follow the standards and recommendations of the company that produces cars of this brand.

Liquid draining process

To remove the pipe, you need to pass a tight clamp. Please note that if there are clamps on the working hoses, you should replace them with new ones, because these elements are designed for one-time use only. Afterwards, the hose is carefully disconnected from the fitting and placed in a container.

Next, the used antifreeze will flow simultaneously from two points: the radiator, the pipe. In order for the coolant to flow more actively, the cap of the expansion tank is removed, as well as the plug valve of the vertical fitting, located on a massive pipe, which goes to the body structure of the thermostat.

The design feature of the “Loganov” cooling system will not allow all used antifreeze to be drained. Some of it will settle inside the heater radiator.

You can perform absolute emptying by loosening the standard clamps, removing 2 pipes (pipes) from the thermostat base and tilting them down towards the container. Then the remaining liquid is removed by compressed air entering the tank, as well as into the thermostat fittings.

The process requires caution: the air pressure must be controlled so that it is not extremely high, since the honeycomb of the stove radiator may be damaged.

After waiting a little until the system is completely empty, you can begin the reverse configuration. The tubes are mounted by tightening them with fresh clamps. Pour in new antifreeze prepared in advance.

At first, the manufacturing company Renault used GLACELFAUTOSUPRА products as a coolant, which had a yellow-red tone. With the onset of 2009 GLACEOLRXTypeD antifreeze from the ELF brand began to be actively used.

This concentrate is yellow in color and requires dilution with distilled (purified) water in a 1:1 ratio, which is quite simple.

Both products, ordered from an official dealer, are still of excellent composition quality and are recommended by Reno Corporation for Logan 2 modifications with 1.4 or 1.6 liter engines. The volume for refilling the system corresponds to 5.5 liters.

How to remove all air from the system

First, you should make sure that all internal plugs have been screwed in. Next is to start the engine. After the engine has warmed up at idle speed and after it reaches 30 degrees, the engine should be stopped. Then the excess pressure is removed. How it's done? The pressure is removed by unscrewing the cap from the inlet side of the engine compartment near the expansion pipe itself.

At the same time, all work on unscrewing and further tightening should be carried out as smoothly as possible without sudden movements, since there is pressure in the system, and it is hot and cool. the mixture can burn your palms. Next, cover the throat with your hand and unscrew the pipe with the other hand. After all the basic manipulations, the palm can be removed. When all the oxygen has gone and the liquid begins to flow, the inlet can be closed and the valve screwed in. Next, tighten the tank cap tightly.

Preparing for work

Coolant is necessary to remove excess heat from a running engine. The productivity of the Renault Logan engine depends on its quality. Particular attention should be paid to replacing antifreeze.

ATTENTION! A completely simple way to reduce fuel consumption has been found! Don't believe me? An auto mechanic with 15 years of experience also didn’t believe it until he tried it. And now he saves 35,000 rubles a year on gasoline! Read more"

Today you can buy any coolant in stores, but for a safe replacement you need to choose the one recommended by the manufacturer. You can find out what antifreeze to buy and how much to fill in from the user manual. Every car manufacturer applies it to their products.

Despite the fact that the French automaker recommends replacing antifreeze after 90,000 km, experienced car enthusiasts insist on a complete replacement of the coolant after a mileage of 60,000 km. The fact is that by this time its color and main characteristics change, it begins to smell unpleasant.

To perform routine maintenance, you will need the following tools and consumables:

• Open-end and box-end wrenches.
• Pliers and screwdriver.
• Low container for collecting antifreeze (at least 6 liters).
• Plastic funnel. If necessary, it can be replaced with the cut off neck of a plastic bottle.
• Fabric gloves.
• Rags.

Before starting work, the car must be driven into the pit. This will make it easier to access the oil pan. In addition, you will have to remove the engine protection: it will interfere with replacing the antifreeze.

An important preparation step is removing excess air from the expansion tank. This should be done exclusively on a cold engine. You should remove the cap from the neck of the tank and wait for the air to escape , after which the cap can be returned to its place.

Logan does not have a specialized coolant drain. Therefore, in order to change antifreeze on Renault Logan, you will first need to place a container under the radiator.

The order of steps for changing the coolant. mixtures

1. Crawl under your car, then you should unscrew the so-called engine protection and remove the inner shield. This shield protects the left side of the engine from dirt getting into it. After this, place a canister under the drain to collect the mixture.
2. Completely unscrew the drain plug of the engine cooling mechanism. Next, you need to unscrew the top part of the filler tank.
3. You can also partially unscrew the plug (if the pressure level drops, unscrew it entirely).
4. After draining the mixture from the radiator, screw everything back in as before. Loosen the compression force of the valve on the internal pipe, then drain the remaining mixture from the engine.
5. Using a pump or syringe, it is worth pumping out the old antifreeze from the expansion tank and pouring in fresh one.
6. Fill with fresh mixture until the mixture flows out. Next, simply close the lid.

Towards the end of replacing the antifreeze, you should definitely turn on the engine of your Logan and let it warm up before starting work (which, in general, will make it possible to make sure that the cooling system is working correctly).

After replacement, check the overall antifreeze level. If there is not enough antifreeze in the tank, bring it to the “F” mark.

• If on a heated engine there is no warm flow from the internal heater, this may indicate the appearance of a water/air plug in the cooling system. If the air is a little warm when the engine is running, then the fan is faulty, but if it is cool, there is a plug in the coolant mixture.
• Loosen the compression force of the valve on the internal radiator pipe, then unscrew it and drain the remaining mixture from the engine.

As can be seen from the text above, replacing antifreeze in a Renault Logan 1.6 8-valve version is essentially a fairly simple procedure. Doing this work on your Logan yourself gives you new knowledge and allows you to save money on repairing your car. This is also an overall great opportunity to get to know your car and see it in a new light.

The above instructions will allow the user to carry out re-solidification of antifreeze on their own without the help of people. Now you know how to do it. As a result, you also get the opportunity to save your money and, in the future, carry out this work more confidently.

Scope of application

Ready-to-use Renault coolant

The original antifreeze from Renault was developed for use in the cooling systems of any modern internal combustion engines. It is best suited for Renault-Nissan engines.

It is completely neutral to metal alloys and rubber compounds, which allows it to be used in cooling systems with copper and rubber parts.

Important! In the event of an antifreeze leak, the manufacturer strongly does not recommend mixing it with other brands of antifreeze, even if they have a similar green color. The best solution would be to add the same antifreeze to the cooling system. If you don’t have the same canister of Antifreeze concentrate Renault Type D with you, you can mix it with ordinary distilled water until the leak is eliminated and all the coolant is replaced.

Reviews

Nikolai, 30 years old Good antifreeze, does not freeze even in the most severe cold. It has to be changed every two to three years. Overall I recommend it.

Maxim, 24 years old I have no complaints about this refrigerant, the only negative is the inflated price.

Yuri, 40 years old I always use this original antifreeze as I try to take care of my car and use only original products.

Evgeniy, 53 years old Having studied reviews on the Internet, I still could not understand how this coolant differs from analogues except for the price. Antifreeze may be good, but its cost is not justified.

Let's summarize

Many car owners skip the flushing step - it is not cost-effective. Old antifreeze, corrosion particles, sediment and other impurities remain in the system. They quickly mix with the new composition, it loses its protective properties. Flushing lengthens the procedure, but also extends the life of the coolant. On the first day of operating the machine, you need to monitor the fluid level. If it decreases, there is air left in the system.
