What kind of coolant should I fill in Renault Sandero?

Renault Sandero has established itself as a high-quality, inexpensive and easy-to-maintain car. The off-road modification of Renault Sandero Stepway is a brother with minor differences. One of which is increased ground clearance, which is ideal for use on Russian roads.

For our market, Renault has slightly adjusted the parameters of both cars and adapted them for operation in harsh conditions. For reliable operation, car owners can only carry out maintenance on time.

Do-it-yourself coolant replacement in Stepway

Every 90,000 km the old coolant is replaced. To perform this procedure, you need to stock up on 8-9 liters of cooling concentrate.

In order to replace a Renault Sandero Stepway, you will need a box with tools and related materials:

• antifreeze directly;
• container for old coolant;
• dry rags;
• pliers.

What is the technology for replacing antifreeze in the French car Renault Sandero Stepway? The process includes several stages that are carried out according to the scheme, and the replacement can be done with your own hands, the main thing is to find out what kind of antifreeze to fill in beforehand:

1. First, the power unit of the machine is prepared. Long before work is completed, it is switched off, since replacement can only be carried out with a cold engine. Then the engine compartment is opened and the cap is pulled off the corresponding filler barrel to relieve pressure.
2. The Sandero does not have a drain hole for the old coolant. Therefore, the crankcase protection is dismantled, after which a 10-liter container is placed under the radiator,

1. To get rid of waste, you need to do it in two steps: remove the clamp at the bottom of the radiator by loosening the fasteners with a screwdriver, after which the pipe is dismantled and the liquid is drained into a container. To speed up the drainage, remove the plug from the fitting on the supply pipeline.
2. After the system is emptied, the radiator parts are returned to their place. The old clamp for the pipe is most likely no longer suitable, so you should purchase a new one.
3. Coolant is added to the expansion tank until it begins to run out of the outlet hole. After this, a plug is put on the fitting, and a lid is installed on the tank.
4. The system is running. The engine is started and left running until the radiator pipe begins to warm up. This means that the coolant has already flowed through the system. After the Renault Sandero, the Stepway becomes jammed.

Choosing coolant

The composition of antifreeze is general, regardless of type: distilled water, ethylene glycol and other impurities. The only differences are in shade and specification. It is the purpose that determines the choice of liquid of one brand or another. The instructions that come with the machine indicate which antifreeze to fill, that is, it should be used to cool the machine’s systems.

At the factory, the Renault Sandero Stepway crossover system is filled with Type D. The color palette of this coolant varies. The factory tint is usually green. However, blue, yellowish or with a red spectrum will also work. The main thing is that it does not contain silicates.

Typically, factories that produce auto chemicals receive approval from automobile companies in the form of permitting certificates. Therefore, antifreeze for Renault Sandero Stepway will have the appropriate marking, in the form of the name Renault, which does not allow you to make a mistake when choosing a refrigerant. So, we found out what antifreeze to fill.

Leaks and problems

When replacing coolant, you should pay attention to defects in the hoses; if there is the slightest doubt about their integrity, then you should take care of replacement.

It is also advisable to inspect the expansion tank; it is not uncommon for the internal partition to simply dissolve over time and clog the cooling system with flakes of plastic particles. To search for and purchase a barrel, you can use the original number 7701470460 or take the analogue MEYLE 16142230000.

The cover is also periodically changed, original 8200048024 or an analogue ASAM 30937, since the valves installed on it sometimes stick. Increased pressure is created and, as a result, leakage occurs, even in a seemingly serviceable system.

There are cases of thermostat failure 8200772985, improper operation or gasket leakage.

The clamps used in this Renault model also cause criticism from motorists.

They come in two types: low-profile with a latch (Fig. A) and spring-spring (Fig. B). Low-profile with a latch, it is recommended to replace it with a regular worm-type one, since it is not always possible to clamp the original one without a special key. A diameter of 35-40 mm is suitable for replacement.

You can try to put the spring-spring one in place using pliers, but this requires a little skill.

Stages of replacing coolant in Renault Sandero

The procedure for replacing antifreeze is quite logical and understandable, although it has a number of nuances that are worth paying attention to. Unfortunately, the manufacturer did not provide drain taps for this task.

Detailed instructions for replacing coolant, suitable for Renault Sandero and Stepway modifications with an engine capacity of 1.4 and 1.6 where 8 or 16 valves are used. Structurally, the cooling system and power plants are similar and do not have any significant differences.

Coolant drain

To carry out an operation to replace antifreeze, it is better to drive the car into a pit or overpass, as we described in the example of Logan, but this is not always possible. Therefore, we will consider the option of replacing it ourselves when there is no hole.

Everything is easy to reach from the engine compartment. The only thing is that it will not be possible to remove the engine protection, because of this the liquid will splash heavily, hitting and flowing down it.

So, let's figure out how to properly drain antifreeze:

1. First of all, we remove the corrugation with the pipe so that subsequent operations can be performed more conveniently. One end just needs to be removed from the air filter housing. And the other end is attached behind the headlight; you need to feel the bulges on the pipe that hold it in place, press on them and remove them (Fig. 1);

Flushing the cooling system

When replacing antifreeze, it is recommended to flush the cooling system; if the replacement is carried out according to regulated periods, then there is no need to use special chemicals. It is enough to run it 3-4 times with distilled water.

To perform this operation, you can simply throw on the hoses without clamping them and warm up the car to the opening temperature of the thermostat. By the fourth time the water will be almost clean, you can start adding new antifreeze.

Filling without air pockets

After flushing the system and drying it as much as possible from distilled water, we proceed to the filling stage:

1. put all the hoses in place, clamp them with clamps;
2. through the expansion tank, we begin to fill the system with antifreeze;
3. As it fills, air will come out through the vent hole, after which clear water will flow, some of which remains in the pipes after washing. As soon as the antifreeze flows, you can close the hole with a cap;
4. add liquid to the level and close the expander.

The main filling operation is completed, all that remains is to expel the air from the system. To do this, you need to start the car and periodically increase the speed to warm it up for 5-10 minutes. Next, unscrew the expander plug and normalize the pressure.

We open the hole for the air to escape, slightly open the expansion tank, as soon as the air comes out, close everything. It is recommended to repeat all steps several times.

Sequence of work

Before you begin replacing Renault Sandero antifreeze, you must ensure that you have the following tools and accessories. So, you will need a small piece of clean cloth, pliers, a container whose volume should not be less than 10 liters and, of course, the liquid itself.

A prerequisite for replacing antifreeze on a Renault Sandero is a cold engine. You also need to take care of personal protection. To do this, you can wear a respirator to prevent vapors from entering the respiratory system, gloves and glasses. The car must be on a horizontally level surface.

Before starting work, you need to check all connections for possible leaks, including the connections between the hoses and the thermostat housing. If the tightening is not tight enough, it is necessary to replace the metal clamps.

First you need to unscrew the cap of the expansion tank of the Renault car cooling system. Also, if there is engine crankcase protection, it must be removed. Then, using pliers, you need to loosen the clamp that secures the lower radiator hose of the car. The clamp is lowered along the length of the hose. At the next stage, you need to remove the hose from the radiator pipe and drain all the contents into a container that was prepared in advance. You must wait until the system is completely empty. After this, you need to tighten the valve plug, which is designed to release air. It is recommended to pour a little water through the expansion tank to flush the pipeline. Then, using a compressor, you need to blow out the remaining water from the system.

The lower radiator hose is installed in its place and securely fixed with a clamp. The new substance must be poured into the system with the valve cap removed to allow air to escape. After the solution begins to emerge from the valve instead of air, you should tighten the cap and cap of the expansion tank. Then you need to start the Renault Sandero engine, allowing the contents to circulate through the system. You can do the replacement yourself without any special equipment.

Step-by-step instructions for changing antifreeze in a car

Immediately before draining and replacing antifreeze in the Renault Sandero Stepway, it is necessary to prepare the car for the upcoming procedure. It is recommended to place the vehicle on a flat horizontal surface, without slopes or vertical elevations.

Important! According to the safety instructions, before changing the antifreeze in Renault Sandero Stepway, it is recommended to turn off the engine, let it cool and only then start working. The coolant heated when the engine is running remains in the expansion tank under high pressure. If the engine is not allowed to cool, a dense stream of antifreeze can burn the car owner's hands and face.

Next, you should take care of the appropriate tools. To change antifreeze in Renault Sandero Stepway you will need:

• Pliers;
• Key for 14 and 16;
• Screwdriver;
• Container for draining used antifreeze, with a capacity of at least 10 liters;
• Absorbent rag fabric;
• If necessary, additional replacement parts (pipes, valves, etc.).

The preparation procedure for changing antifreeze in a car’s cooling system usually takes no more than 1 hour. The process of replacing the coolant itself is divided into 3 stages sequentially:

• Stage 1 - draining outdated coolant from the Renault Sandero Stepway cooling system: The drain container is installed under the expansion tank;
• After the engine has cooled, carefully unscrew the drain tank cap. This is not recommended to be done abruptly due to the residual high pressure in the unit housing;
• Allow the used coolant to drain into the prepared container. In this way, you can test for clogging in the drain - if the substance does not pour out freely, this means that the drain is severely clogged;
• After draining used antifreeze, it is recommended to examine the contents of the drain container. If the technical fluid used is cloudy and has a pronounced sediment, this may indicate a corrosion process in the cooling system of the Renault Sandero Stepway;
• Screw in the drain plugs and return the expansion tank to its original position;
• Move the drain container under the vehicle cylinder block;
• Drain used antifreeze from the cylinder block;

• Stage 3 - pouring fresh antifreeze. After the flushing has been completed, fresh coolant is poured into the expansion tank. It is important to note that if antifreeze concentrate is used as a coolant, it should be diluted with distilled water. The ratio of liquids depends on the desired boiling point of the substance and is indicated in the instructions for use of the concentrate. Then all the plugs are carefully screwed in, and final checks are made for the tightness of the cooling system, absence of leaks and defective parts.

The recommended brands of antifreeze for Renault cars are category D coolants - for example, Glaceol RX and Cool Stream 4030 Premium.

What to do if air gets into the cooling system?

During the process of replacing antifreeze with Renault Sandero Stepway, air enters the vehicle's cooling system. Getting rid of excess air is not difficult, just follow the action plan below:

• After filling in new antifreeze, start the car engine;
• Leave the car idling for 10-15 minutes;
• Stop the engine and examine the coolant readings. If the readings have decreased, add the missing amount of antifreeze.

This procedure is called running the engine. As a result of the run, the air freely leaves the Renault Sandero Stepway cooling system, providing the vacuum necessary for normal engine operation. It is enough to carry out this procedure only 1 time.

Replacement frequency, what antifreeze to fill

The manufacturer recommends replacing the coolant after 90,000 kilometers or 3 years of operation. In most cases, this period is optimal, provided that you use the recommended antifreeze.

If you fill in the original liquid, then it will of course be Renault Glaceol RX type D, code 7711428132 liter bottle. But if you can't find it, don't be upset.

Renault Sandero can also be filled with other antifreezes from the factory, for example, Coolstream NRC, SINTEC S 12+ PREMIUM. It all depends on the place of production of the machine and the concluded supply contracts. Since it is expensive to transport “water” from abroad, it is cheaper to use what is produced by local enterprises.

If we talk about analogues or substitutes, then any brand that has Type D approval recommended by the French automaker will do.

Volume table

Choice

For example, in engines with a volume of 1.6 liters, it is advisable to use fluids similar to D-GLACEOL RX, it has average viscosity values, and the color has a yellowish tint. Quite often, Renault owners fill in Cool Stream 4030 Premium coolant. The color it has does not affect the quality of the substance in any way.

All models, regardless of the year they were released, hold about 5.5 liters of liquid. The expansion tank has special marks by which you can find out the volume of the substance. They also use a special concentrate that is diluted with water, they have the following article numbers 7711170546 and 7711170545

An excellent option among popular brands are Lukoil Antifreeze Ultra G12, Liqui Moly kfs 2001, Febi korrosions Frostschutmittel, etc. When choosing, a prerequisite must be the presence of code D. It is advisable to use one type of antifreeze for Renault Sandero, since the use of different mixtures can lead to failures in the operation of the entire system. Since the liquid may thicken, plugs will appear that will interfere with normal circulation.
