Replacing antifreeze in the Renault Logan cooling system

Recommendations for preparation

The manufacturer recommends changing the coolant every 90 thousand km or after 6 years of operation. It is better to replace the antifreeze earlier, when it acquires a dirty brown tint and begins to emit a sharp, unpleasant odor: at approximately 60 thousand km. To perform the operation, you will need to prepare tools and consumables:

• Standard set of open-end or ring wrenches.
• Pliers.
• Screwdriver.
• Wide container with low sides with a capacity of up to 6 liters for draining waste.
• Funnel, you can use the cut off neck of a plastic bottle.
• Fabric gloves.
• Rags.

It is more convenient to replace antifreeze if there is an inspection ditch. Otherwise, the oil pan protection will have to be unscrewed and removed while lying under the car, and the engine should not be warmed up. Before starting work, remove excess pressure in the cooling system by unscrewing the cap from the neck of the expansion tank. Air will escape from it with a characteristic sound, after which the lid must be screwed back on.

Renault cars do not have special fittings or plugs, and draining is carried out by removing the cooling system pipes, first of all, the lower hose from the radiator. First you need to unscrew and remove the oil pan protection and place the prepared container under the radiator. If work is carried out from a viewing hole, then a board thrown over the ditch can serve as a support for the container.

Technical minimum

Actions to replace the freezing liquid - antifreeze require the preparation of the following accessories:

• pliers;
• screwdriver;
• a set of keys - open-end or spanner;
• a container with low sides with a capacity of about six liters for filling with used antifreeze;
• cloth work gloves;
• funnel (the cut off neck of a plastic container can also be used);
• rags.

The presence of a ditch will allow you to conveniently replace antifreeze. If it is not there, then you will have to twist and remove the oil pan protection while lying under the car. The engine must be cold during operation. Preparatory work also includes eliminating excess pressure in the system. This process looks like this: after unscrewing the cap from the expansion tank and releasing the air (the air flow will create a specific sound when escaping), screw the cap back on.

Fittings and plugs are not required for manipulations to drain antifreeze from Logan 2. The process is carried out by removing the cooling system pipes, and first, the lower tube from the radiator installation. Before you begin these steps, you need to remove the metal pan that protects the crankcase, and then place the prepared container under the radiator. When carrying out operations from a garage inspection pit, a board thrown over the ditch opening can be used as a support for the container.

Procedure for draining old fluid

To remove the pipe, you need to loosen the tight clamp. Advice: if the hoses have “original” Renault clamps, then it is better to replace them with new ones, since they are intended for one-time use. Next, the hose is carefully removed from the fitting and directed into the container; the used antifreeze will flow out of the radiator and the pipe simultaneously. Now you can unscrew and remove the cap of the expansion tank and the plug from the small vertical fitting located on the thick pipe leading to the thermostat housing. At the same time, the coolant will flow more intensely.

Due to the design of the Renault cooling system, the old antifreeze cannot be drained immediately; some of it will remain in the radiator of the cabin heater. To completely drain the liquid, you need to unlock the clamps, pull off two more pipes from the thermostat body and point them down into the container. After this, the remaining coolant is removed from the system by supplying compressed air to the neck of the expansion tank and the fittings of the thermostat housing. This operation must be done carefully; the air pressure should not be high, otherwise the honeycomb of the interior heater radiator may be destroyed. We recommend watching the video:

When the system is completely empty, you can reassemble it. All pipes of the system are installed in their places, tightening them with new clamps. Now you can fill in new antifreeze. Previously, the Renault manufacturing plant used the TOTAL brand GLACELFAUTOSUPRA product, yellow or yellow-red in color, as a coolant. Since 2009, GLACEOLRXTypeD, produced under the ELF brand, has been used. The latter is yellow in color; before pouring, the concentrate is diluted with distilled water in a 1:1 ratio, regardless of volume. Both products, purchased from an official sales representative, are of high quality and are recommended for use in Logan cars with 1.4 l or 1.6 l engines, the filling volume is 5.5 l. The appearance of liquid packages with different volumes can be seen in the video:

Drain the old fluid

The pipe in the Renault Logan is removed when the lock nut is first removed from the tightening clamp. Recommendation: if the hoses are secured with original Renault clamps, then they are replaced with new ones, since the old ones are disposable. Afterwards, the hose is twisted from the fitting and lowered into the container. The waste will drain in parallel from the pipe and the radiator. Then remove the cap of the expansion barrel and the plug from the vertical fitting located on the wide pipe fitting to the body of the thermostat. This is to increase the intensity of antifreeze drainage. And the coolant is replaced correctly and faster.

Due to the design features of the Renault Logan cooling system, these actions will not allow all the coolant to drain. A certain amount of it will remain in the radiator of the interior heater. To completely drain the waste, the pipes are unlocked and the clamps are removed from the two hoses that go to the thermostat, and the tubes themselves are lowered into the drain container. Then the cooling system is purged using compressed air supplied through the neck of the expansion tank and the holes in the thermostat housing. The operation is performed carefully without excessive pressure. Otherwise, the honeycomb of the interior heater radiator may be deformed.

After a certain time, during which the cooling system is completely empty, you can reinstall all components. All hoses are returned to their original places and secured with new clamps. Afterwards, new coolant is poured in, but which brand is decided by each individual. For some time, the Renault automaker filled the system with GLACELFAUTOSUPRA antifreeze from the TOTAL brand, painted in a bright yellow and pure yellow color spectrum. Since 2009, when antifreeze is replaced, GLACEOLRXTypeD, produced under the ELF brand, is poured into the system. It has a yellow tint, and before filling, the concentrate is diluted in a 1:1 ratio with distilled water for any volume. These two brands of antifreeze are characterized by excellent quality and are used for use on the French sedan Renault Logan with a 1.4 and 1.6 liter engine. They are purchased from the official Renault distributor. When replacing antifreeze, many are interested in the volume, it is within 5.5 liters, and the color of the liquid is determined through an Internet search. The outer packaging can be viewed in the corresponding video.

Instructions for filling the system

Using a funnel, new antifreeze is poured into the Logan system through the neck of the expansion tank - the drain plug must be unscrewed. You should pour slowly, taking pauses, during which you should press all the pipes with your hands to remove air pockets. The process continues until a trickle flows from the fitting. At this moment, you need to quickly remove the funnel from the neck and close it with your right hand, stopping the liquid from flowing out. With your left hand, tighten the fitting plug and add the required amount into the expansion tank. The level should be located between the minimum and maximum marks.

What and how much to fill in Renault Logan

Logan is equipped with only three engines: 1.4 liters. 8 valves; 1.6 l. 8 valves; 1.6 l. 16 valves.

If we take the first two engines (1.4 l. 8 valves; 1.6 l. 8 valves), then their volume does not change (3.3 l.) and neither does the oil (ELF EVOLUTION SXR 5W30). But in the case of 1.6 liters. 16 valves, then the oil (ELFEVOLUTION SXR 5W40) and volume (4.9 liters) change.

Here you already need to pour the same antifreeze into all engines: GLACEOL RX Type D, and the volume also does not change - 5.45 liters. Before using antifreeze, it must be diluted with distilled water, the proportion is one to one. In this case, your liquid will solidify only at a temperature of -36 degrees.

The tank has a volume of 50 liters, you need to pour gasoline of at least 92 octane.

For manual transmissions, ELF Tranself NFJ 75W80 or Elf Tranself TRJ 75W-80 oil is used, and the fill volume is 3.1 liters.

Which antifreeze to add for cooling?

We fill in original antifreeze for Renault Logan...

Hello dear readers of the blog AAuhadullin.ru. Today we’ll talk about what kind of antifreeze for Renault Logan cars to pour into the expansion tank under the hood, since regular maintenance of the cooling system is very important to maintain the longevity of the engine.

According to the maintenance regulations for the Reno Logan car, it is recommended to replace antifreeze every 90 thousand km completely. New chemical compositions of coolant have properties that increase the replacement period to 100 thousand kilometers. Manufacturers of the chemical product recommend pouring new fluid only into a clean environment, since the properties and anti-corrosion qualities of the poured new clean antifreeze are less effective when mixed with waste.

The chemical composition of antifreeze for Renault Logan includes substances such as ethylene glycol, distilled water and additives, that is, a special composition based on an aqueous solution of glycerin and alcohol. Ethylene glycol and distilled water make up approximately 96% of the total volume of the liquid, and the rest is occupied by corrosion inhibitors and additives, on which the quality of the coolant depends. The anti-corrosion properties of additives are used in various cooling systems, including cast iron, copper and aluminum radiators.

For Reno Logan, the official dealer recommends a type “D” product under the ELF brand with the name “GLACEOL RX Type D 1L Renault 7711428132”.

From the manufacturer Total, the branded product is supplied for refilling in the form of a concentrate in 1 liter plastic containers.

Before adding the antifreeze concentrate to the expansion barrel, it must be diluted in advance with distilled water in half (50 to 50); for dilution, you can use a clean bottle or other container.

Total antifreezes do not harm plastics, rubber products, paints and varnishes. The diluted composition of the concentrate with water in half (50 to 50) is stable in winter to freezing temperatures from -35 to -40 degrees. By changing the percentage of concentrate with distilled water from 30 to 70, you can use the machine to dilute it for different climatic temperatures.

To fully charge the Reno Logan cooling system, you need to prepare in advance from 6 to 8 liters of antifreeze composition diluted to the required concentration, depending on the car’s engine volume. Therefore, it is advisable to immediately purchase at least 3-4 liters of ELF GLACEOL RX Type D antifreeze. The remaining diluted coolant. During the operation of the car, the liquid is used for topping up with your own hands.

The product GLACEOL RX Type D currently costs approximately 330 rubles per 1 liter plastic container. You can buy the original antifreeze concentrate recommended by the manufacturer for Renault Logan at the spare parts warehouse from an official TTS dealer. They also have distilled water for dilution; by the way, it freezes in winter.

Preparing to replace antifreeze on Renault Logan

When the liquid acquires a dirty color and begins to smell sharp and unpleasant, you need to change it. This can happen already at 50 - 60 thousand mileage.

The question immediately arises of which antifreeze to choose. On this topic, see the test from the Main Road .

Some of the best brands are Liqui Moly Langzeit GTL12 Plus, SINTEC LUX G12, Felix Carbox G12. You can also pay attention to the companies Shell, Texaco, Total, Lukoil and BASF.

Remember that the color of the coolant does not affect anything because they are all colorless fluids to begin with. Giving them blue or green is at the discretion of the manufacturer.

We list the tools that you will need to replace antifreeze on Renault Logan.

You will need tools and materials

• antifreeze 5.5 liters;
• any set of open-end or ring wrenches;
• pliers;
• slotted screwdriver;
• worm clamps with a diameter of 35 - 50 mm - 4 pcs.;
• a basin or cut-off low plastic canister with a volume of 6 liters for draining bad antifreeze;
• a plastic funnel, although you can cut a plastic bottle;
• gloves for car maintenance;
• rags or rags.

To drain, it is better to place Logan over an inspection hole or drive onto an overpass. If this is possible, which most often happens, then lay a blanket under the car so that you can lie on it. At the same time, do not forget to put on the speed, handbrake and chocks under the wheels of your car.

Before draining the old coolant, you need to let the engine cool down so that there is no excess pressure in the cooling system. While the engine is cooling, you can remove the crankcase protection under the engine, if present. Then place a container for the used coolant under the drainage area.

If you have not allowed the engine to cool completely, it is better to relieve excess pressure by opening the cap of the coolant expansion tank. Be careful because excess steam may escape and should not be inhaled. Then close the expansion tank cap to reduce the initial flow of fluid when unscrewing the drain hose. After unscrewing this hose, the tank cap must be removed.

Replacing antifreeze Logan

On the Logan model, correct replacement of antifreeze involves:

• drain;
• washing;
• filling with fresh liquid.

In this case, it is necessary to flush the system, since when draining, old antifreeze (up to 1 liter), rust particles, impurities and deposits partially remain in the block and hard-to-reach areas. If such elements are not removed from the system, the fresh fluid quickly becomes contaminated, the service life of the antifreeze is shortened and the efficiency and reliability of the entire cooling system is reduced.

Taking into account the fact that Logan can have several types of engines (diesel, gasoline of different volumes), some replacement features may differ depending on the type of internal combustion engine (the most common are 1.4 and 1.6 gasoline units).

However, the general procedure for changing Logan antifreeze in all cases is practically the same:

• prepare about 6 liters of ready-made antifreeze (concentrate diluted with distilled water in the required proportions 50:50, 60:40, etc.);
• then the car needs to be driven into a pit or raised on a lift;
• then the engine should be allowed to cool to an acceptable temperature to avoid burns and injuries;
• taking into account the fact that there is no drain plug on the Renault Logan radiator, you will need to remove the lower pipe;
• to remove the pipe, remove the engine protection (6 bolts are removed), the left engine boot (3 screws and 2 pistons);
• Having gained access to the pipe, you need to place a container for drainage, remove the clamp and pull the hose up;
• Please note that low profile clamps require a tool to remove and are also more difficult to install. For this reason, they are often replaced with simple worm-drive clamps of good quality (size 37 mm).
• While the antifreeze is draining, you need to unscrew the cap of the expansion tank and open the air release valve (located on the pipe that goes to the interior heater).
• you can also blow the system through the expansion tank (if possible) to drain all the antifreeze;
• By the way, there is no drain plug on the engine block, so it is optimal to drain the coolant as thoroughly as possible using available methods;
  After draining, you can put the pipe back in place and proceed to flushing or fill in with fresh antifreeze. Having filled in the liquid in full, you need to warm up the engine, make sure the system is tight and check the coolant level again (the norm is between o and “max” on a cold engine);
• It may also be necessary to remove any air pockets from the system. To do this, open the expansion tank cap, position the car so that the front part is higher than the rear, after which you should actively accelerate at idle speed.
• Another way to remove air is to open the air bleeder, close the reservoir cap and warm up the engine again. If everything is normal, the system is sealed and the stove blows hot air, then the Renault Logan antifreeze replacement was successful.

How to drain old antifreeze in Renault Logan

There is no drain plug for draining antifreeze in Renault Logan, so you have to drain it by removing the cooling pipe. We are talking about the lower pipe of the cooling radiator, secured with a clamp.

To open the drain hose clamp, you need to insert a slotted screwdriver into its lock, as shown in the photo (the hose has been removed for clarity), and turn the screwdriver.

Advice: if the hoses have “original” disposable clamps from Renault, then it is better to replace them with clamps with a worm gear.

Remove the hose from the radiator pipe and drain everything into a container.

In order for the liquid to flow faster when draining, you need to remove the plug from the vertical fitting, which is located on the thick pipe near the thermostat.

Due to the design of the cooling system in Renault Logan, not all of the antifreeze is drained, because some of it remains in the interior heater radiator . To drain the antifreeze from there, you need to remove two more hoses from the thermostat and tilt them down. After the residue has flowed out, you can blow air out of these hoses.

You have to be careful when blowing, because excess pressure can bend the delicate radiator lamellas. The video shows how to properly drain the coolant yourself.

Removing old fluid

Do not attempt to pull off the lower radiator hose without first loosening the tension clamp. When removing the locknut, you need to inspect the clamp. If it is original, it will have to be replaced. The French automaker supplies disposable clamps.

Next you need to proceed in the following order:

• The hoses are removed from the radiator and the expansion tank pipe. This will allow you to quickly drain the Renault Logan antifreeze and ensure a high-quality replacement in the future.
• Due to the design of the car, simply disconnecting the hoses will not completely get rid of antifreeze. Some of it will remain in the radiator. To completely remove antifreeze, you need to remove the tubes from the thermostat hoses and lower their container with the drained liquid.
• The cooling system is purged using a compressor. Air must be supplied simultaneously - through the expansion tank and thermostat hoses. The pressure should not be excessive to prevent damage to the radiator honeycomb.
• After the cooling system is completely empty, you can return all hoses and clamps to their place.

After the procedures have been completed, you can begin to fill in new fluid. The choice of antifreeze is up to the car owner. There was a time when Renault engineers recommended using antifreeze called GLACELF AUTO SUPRA produced by Total. It is easily recognized by its orange color. But today the automaker recommends using Renault Glaceol RX Type D. Antifreeze of this brand is available in the form of a concentrate, and before filling it must be diluted with distilled water.

Preparing to fill coolant

After the antifreeze stops leaking, you need to put new clamps with a worm tightening mechanism on the hoses and put the hoses in their original place, after wiping the connection points from dust and dirt with a cloth.

After this, you can fill in new fresh coolant.

Glaceol RX Type D as antifreeze , produced under the ELF brand, which is painted yellow and obtained from a concentrate diluted with distilled water in a 1:1 ratio. It is recommended for use in Renault Logan with 1.4 l or 1.6 l engines.

If your Renault Logan has problems with engine cooling, then the first thing to suspect is the thermostat. Watch the video to see which thermostat company to install

Drawing conclusions

Like any Renault Logan car, engine capacity 1.4 and 1.6 needs attention and quality service. It is recommended to change the coolant every 2 years. You definitely need to pay attention to what kind of coolant you will be pouring into your car. This operation is not difficult to perform, so you can do it yourself. You should choose high-quality refrigerants, paying attention to the compatibility of this liquid with the modification of your car, because a lot depends on what kind of antifreeze you use.

How to properly fill antifreeze into Renault Logan

It is better to pour into the expansion tank using a plastic funnel. In this case, you need to remove the lower drain hose of the cooling system and wait for the coolant to flow out of it. Remember - there is no need to rush when pouring coolant - take breaks and pump excess air in the hoses by pressing on them.

When liquid flows from the lower hose, you need to close the neck of the expansion tank to stop the flow. Next, you need to put the hose in place and tighten it with a clamp. After this, add coolant to the expansion tank up to the MAX mark on the tank. The next step is to bleed the air from the cooling system hoses. The following procedures are recommended.

How to remove air from the cooling system

• After tightening the clamps, filling in antifreeze and closing the expansion tank cap, you can try to start the engine. Warm up the engine for a couple of minutes at idle speed to a temperature of about 40 ⁰C and turn off the car .
• Slowly and carefully open the expansion tank cap to release excess pressure. Bleed the cooling hoses to remove air. If there is gurgling in the expansion tank and the level decreases, then add fluid to the middle mark.
• Then we repeat warming up the engine, but to a temperature of 90 ⁰C with the tank cap closed so that the air comes out of the interior heater radiator and the cooler enters there. To warm up the engine faster, you can raise its speed with the gas pedal to 2000 rpm. Don't forget to turn off the engine in time to prevent it from overheating. This can be done as soon as the cooling fan motor starts up.
• Using rubberized gloves, carefully remove the expansion tank neck cap. Carefully! The steam is very hot - up to 100 ⁰C, so it is better not to try to sniff this steam and open the cap at the same time.
• Now you can bleed air from the fitting and add antifreeze as needed. It is better to repeat the procedure of warming up and deflating 2-3 times and after that you can drive. The next day, check the level in the reservoir by leaving your Logan on level ground.

If you still have questions about removing air from Logan’s cooling system, watch the video about this process.

Filling into the system

To replace antifreeze with Renault Logan, you need to use a funnel. You will have to fill the liquid through the inlet pipe after unscrewing the fitting cap.

There's no need to rush. The liquid must enter the system evenly, which will avoid the formation of air plugs. You should also knead all system hoses by hand from time to time.

Filling is completed after antifreeze flows from the fitting. Here it is important to quickly close the filler hole with your hand to prevent antifreeze from escaping through the outlet valve. With your free hand, you should quickly replace the fitting plug, and then check the fluid level in the expansion tank. It should be halfway between the minimum and maximum marks. If necessary, you can add the required amount of liquid.

The work doesn't end there. It is necessary to rid the system of excess air. This procedure goes as follows:

• The reliability of fixation of all covers and clamps is checked.
• The engine starts and warms up in neutral gear to 40 ° C. For precise temperature control, you can use a temperature sensor with a digital display.
• The engine is turned off and the expansion tank cap is unscrewed. You need to be careful with the lid. The pressure in the tank will be excessive.
• After bleeding the air, close the neck of the tank with one hand, and remove the cap from the fitting with the other. After liquid emerges from the drain valve, the caps return to their place.
• To release air from the heater radiator, a pump is connected and the engine is started. The latter should operate at 2,000 rpm for 10 minutes.
• After turning off the engine, you need to bleed excess pressure from the expansion tank again. It is recommended to repeat the procedure several times before full operation.

It is worth remembering that after replacing the antifreeze and carrying out all the necessary manipulations, there will still be air in the system. Its presence will be visible by temperature fluctuations in the system. Therefore, over the course of a month, it will be necessary to bleed off excess air from time to time.

Flushing the Renault Logan cooling system

If you suspect your Renault Logan of clogging the engine cooling system, then you need to use radiator flushing. How do you know when flushing is required? It’s very simple - if on a warm engine a part of the cooling radiator is cold, then you need to flush the radiator.

If the engine overheats without a visible leak of antifreeze and in the absence of air pockets, then you need to flush the engine cooling channels. The question again arises - what kind of flush can be safely used?

The most popular manufacturers of washes can be considered Liqui Moly (Liqui Molly) “Kuhlerreiniger”, HI-GEAR 7 minutes or LAVR 2in1. We would strongly advise against traditional methods of washing with anti-scale or acid - it is better not to use them at your own peril and risk. Watch the video of how professionals do it and everything will become clear.
