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.
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.

Renault Sandero cooling system
In order to ensure a stable temperature of the operating power unit, the French Renault Sandero hatchback and its off-road version Sandero Stepway are equipped with a liquid-type power unit cooling system with forced circulation in a small and large circle.
The protection of the motor from overheating and the ability to reach the required temperature depend on its performance. Technical, located in Kazan, provides professional, prompt and high-quality service to Sandero Stepway and Sandero, including diagnostics of the cooling system with subsequent repair or replacement of faulty parts and assemblies.
Renault Sandero repairs are carried out using special tools and modern equipment. All Renault spare parts necessary for repairs are available in a wide range at the Renault store, located on the territory of the technical center.
The store's assortment of original and non-original Renault Sandero spare parts is of consistently high quality at affordable prices.
Specifics of cooling fluid
The cooling system of the French hatchback is liquid; an expansion tank is installed to fill and top up coolant.
The coolant used is a special antifreeze, the main element of which is ethylene glycol, does not freeze at a temperature of - 40.00 ° C, with anti-foaming and anti-corrosion special additives, including additives that prevent the formation of scale.
Our technical center technicians strongly advise against pouring ordinary or distilled water into the cooling system; this reduces the efficiency of the system and can lead to its failure.
Renault Sandero coolant is replaced every ninety thousand kilometers or after three years of intensive use, depending on which event occurs first. All work is carried out by car mechanics very carefully, since antifreeze is a toxic liquid and should not come into direct contact with the skin or inhale the resulting vapors. When diagnosing, much attention is paid to the tightness of the system in order to prevent vapors from entering directly into the cabin.
Design features of the cooling system
The cooling system of a French hatchback consists of several important components and parts, which include:
- Renault Sandero cooling fan with an electric drive, in a casing with a guide diffuser and an impeller with six blades, asymmetrical, is additionally capable of turning on when the flow of oncoming air is extremely insufficient to cool the antifreeze of the radiator, for example, in the city, on mountain serpentines or when in hot weather, the engine ECU is responsible for turning it on;
- the pump (pump) is of a centrifugal type, equipped with blades, driven by a timing belt, responsible for circulating the filled coolant directly in the system;
- Sandero radiator for cooling heated liquid;
- pipes and a whole set of hoses responsible for the transfer of antifreeze in the system;
- thermostat, provides control of fluid movement along existing circuits (large and small, it all depends on the temperature of the antifreeze);
- heater radiator connected to the cooling system;
- expansion tank designed to compensate for the increase in the volume of antifreeze when heated and to top it up or replace it.
One of the elements of the system is the cooling jacket of the power unit. The operating temperature of antifreeze in the cooling system of a French hatchback is in the range from 90.00°C to 100.00°C, it is maintained automatically using a thermostat. Overheating or, conversely, insufficient heating of the engine indicates that the thermostat needs to be replaced.
The radiator with a horizontal circulation direction of the antifreeze flow has a tubular-tape inner core made of aluminum, two plastic tanks, a tank on the left with outlet and inlet pipes leading directly to the engine cooling jacket. Replacing the radiator, its prevention (cleaning the honeycombs of debris) and repairs, if possible, are services provided by the car mechanics of our technical center.
The water pump is installed on the cylinder block; if it breaks (the seal is broken, the bearings fail), the pump is replaced. This unit is not repairable, so it must be replaced as an assembly.
The expansion tank is made of translucent plastic, with “MIN” and “MAX” marks, which allows you to clearly control the existing level of antifreeze in the system, and is equipped with inlet and outlet valves.
Jamming of the exhaust valve in the closed position can lead to a critical increase in pressure directly in the cooling system, its depressurization, failure of the radiator and overheating of the engine, so diagnostics are necessary and vital.
Is the engine overheating or not reaching operating temperature, have you found any antifreeze leaks?
Immediately contact the Technical Specialists, who work from morning (9:00) to evening (21:00) seven days a week, without days off or breaks.

Choosing coolant
For the cooling system of a Renault Sandero 1.6 liter engine, identical fluids similar to D - GLACEOL RX should be used. It is colored yellow and has an average viscosity. Part of the Renault model range, a certain type of assembly, can be filled with Cool Stream 4030 Premium brand antifreeze. Of course, the color spectrum has absolutely no effect on the properties and functional qualities of the substance.
Regardless of the year of manufacture of a particular Renault Sandero 1.6 model, the cooling system holds 5.45 liters of liquid. There are marks in the expansion tank that act as a guide for the driver to find out how much of the substance is currently in the system. It is possible to purchase a concentrate in order to subsequently dilute it with plain water. Basic fluids for cooling a 1.6 liter engine for Renault Sandero are products labeled 7711170545 or 7711170546.
What antifreeze should I use? A good option for interchange could be antifreeze brands Liqui Moly KFS 2001, Bizol Antifreeze G12+, LUKOIL ANTIFREEZE ULTRA G12 and Febi Korrosions Frostschutmittel. This set is incomplete. However, these fluids showed the best parameters when operating the French crossover Sandero. You should use a substance with code D - this is a prerequisite. Creating different mixtures based on the use of several antifreezes can cause system failures. The substance, in this case, can thicken, which is a prerequisite for the appearance of plugs and, as a result, a negative effect on the pipeline part of the Renault Sandero engine.
