"State Employee" and Corrosion - Whose Wins? Galvanization of Renault Sandero body Renault galvanized body

Renault Sandero is a compact budget car, produced since 2007, available in a five-door hatchback body. This car is inexpensive, and vehicle maintenance is also affordable. Externally, the Sandero resembles the Renault Logan, but the hatchback design is more attractive.

The French model was first presented in Brazil, and a little later shown at the Geneva Motor Show. In Romania, Sandero is known under the Dacia brand; in 2009, the car began to be sold in Belarus and Ukraine.

At the end of 2009, the assembly of the hatchback began to be carried out at the Moscow automobile plant "Renault Russia", the car created on the Nissan B platform. There is also a version of the Renault Sandero Stepway, which differs from the standard model in increased ground clearance (by 20 mm), more impressive wheel arches and roof rails.

Many of the parts installed on the Sandero were borrowed from the Logan, so they are typical characteristic diseases the hatchback took over from its prototype. In 2012, an updated version of the Sandero Stepway was presented to the world, and the second generation Sandero debuted at the Paris Motor Show.

Body and paintwork

The body of the Renault Sandero is galvanized, and the body iron itself is quite durable. These cars rarely rust; corrosion mainly occurs if the car has been in an accident. The paintwork on the body is not bad, chips primarily appear on the wheel arches, in the area of ​​the sills.

What disadvantages do engines have?

There are no powerful engines in the Sandero line of power units, and you can’t count on sportiness here. The most popular is a four-cylinder engine with a volume of 1.4 liters and a power of 72 or 75 horsepower (8 valves).

The car is also equipped with a 1.6 liter internal combustion engine in two modifications:

16-valve – 84 l. With.;

8-valve – 106 l. With.

The 1.4 liter engine is somewhat weak, its thrust is not enough for a relatively heavy car. Often this motor works at the limit, and from the load power unit resource is noticeably reduced. The 1.6 liter 8-valve internal combustion engine is also not very powerful, but it is enough for city trips. With a 16-valve engine, the Sandero has enough dynamics, but the car consumes noticeably more fuel.

Timing belt for 16th grade It is recommended to change the internal combustion engine of the K4M model every 60 thousand kilometers; it is better to replace parts of the gas distribution mechanism as a set (belt, water pump, tension rollers).

The Renault Sandero engine range also includes a 1.5 DCI diesel engine; depending on the modification, its power ranges from 80 to 90 hp. With. The K9K diesel power unit is characterized by high efficiency and good traction, but in Russia cars Sanderos with diesel engines are rare.

The gasoline engines installed on Sandero are quite reliable, but they still encounter some problems. One of the characteristic "diseases"– jamming of the thermostat; with such a defect, the motor may overheat or, conversely, operate at low temperatures. They don’t “live” too long yet spark plugs and high voltage wires, they often break through due to dampness.

Sandero gasoline engines have a very good service life, with proper care and careful operation serve 500 thousand km and more until major repairs.

Weaknesses in transmission units

Only two types of transmission are installed on the hatchback:

5-speed manual transmission;

4-speed automatic transmission.

The automatic transmission is paired with a 16-valve 1.6-liter engine, while the manual transmission is paired with an 8-valve engine.

Mechanical box quite noisy, but at the same time no defects are detected in it - gears are switched smoothly, without jerking, speeds do not slip. Even at engine speeds of three thousand or more, vibration appears on the body, it comes precisely from the manual transmission.

The manufacturer does not provide for changing the oil in the “mechanics”; the lubricant should be enough for the entire service life of the gearbox. But if the transmission has already covered 100 thousand km, it’s better to change the oil in the unit, it won’t make things worse.

Four-speed automatic transmissions are not particularly reliable; automatic transmissions are mostly fail due to overheating. An automatic transmission often requires repairs after a mileage of about one hundred thousand kilometers; the oil in an automatic transmission should be changed after 50 thousand km.

Chassis and sores in the suspension

The rear suspension on the Sandero is a beam type, the front is a standard MacPherson strut. The design of the car's chassis is quite simple, so suspension elements generally fail rarely. Spare parts for the car are relatively inexpensive, and repairing the chassis is not very difficult.

First to use Renault Sandero bushings and stabilizer links are “surrendered”, they serve on average 50-60 thousand km. Rear and front shock absorbers are sensitive to the quality of the road surface and begin to leak quickly if the car is often driven on bad roads. But in any case, the service life of these parts is at least forty thousand kilometers; the original shock absorbers last longer (70-80 thousand km each).

Steering rack not very “tenacious”, first of all the plastic bushing wears out. The manufacturer did not provide repair kits for the rack, but parts can be supplied from another car model, for example, from BMW. Before repairing the steering mechanism, you should check the play in the tips and rods, the service life of which is 60-70 thousand km.

Life time front brake pads are standard - on average about 30-40 thousand km. If you lubricate the guides of the front calipers, the pads may last longer, and the service life of the parts largely depends on your driving style.

Vehicle interior

The interior of the Renault Sandero is nothing special - the interior looks gray and somewhat dull. But there is enough space inside the car, but the trunk of the car is small (320 liters), although if you fold out the rear seats, it becomes quite roomy (1200 liters). The plastic interior is not of very high quality, but the Sandero still belongs to the budget class, and therefore you should not expect the best from the interior trim here.

Diverse and harsh climates create serious requirements for anti-corrosion treatment of their cars. Sudden temperature changes, high air humidity, salt, and de-icing agents can eat away at the body of a car in just a few years. For this reason, in order to take a strong place in the Russian market, the designers of the Renault Logan car had to seriously rack their brains. But first things first.

Renault Logan I generation

The Renault Logan car began its journey on Russian roads in 2005, when the still completely new model uncertainly occupied the automobile market, gaining the trust of potential buyers. In the first year of serial production of cars, problem areas appeared on a certain percentage of cars in the form of spots and traces of corrosion on various parts of the body.

Problem areas

These turned out to be: wheel arches, trunk opening, windshield frame and parts of the roof under the door seals. And among other things, cracks were found in the paintwork near the joints of the rear pillars and the roof of the car. As they say, the first pancake turned out to be lumpy. However, due to the fact that the release of the new model was widely announced by the media and caused a great stir, such problems in Renault Logan were not only overgrown with many myths and rumors, but were sometimes even exaggerated.

One of the most problematic places in old Logan is the doors.

Foci of corrosion appeared on cars produced mainly between 2005 and 2006. Formally speaking, such violations in the paintwork (paint and varnish coating) did not require any warranty service, since they appeared after its completion.

Often the door opening begins to rust

However, the fact remains that the real problem has been identified. Then the Renault concern took unprecedented measures to extend the warranty on paintwork, and in order not to lose the trust of customers, it recognized all facts of corrosion as a warranty case.

Underbody of the car

The bottom of the car practically does not suffer from rust. The ground clearance allows you to catch road unevenness less and scratch the bottom from potholes.

The decision to fully galvanize the body

The concern claims that the Renault Logan body is galvanized during production, but many Renault Logan owners do not trust this information

In order to avoid future problems with manufactured cars, it was decided to galvanize almost all external parts.

In addition, for the purpose of additional protection of the body, the technology of “sacrificial anodes” was used, which were installed mainly in door hinges in the form of inserts and corroded instead of iron. The guarantee for the anti-corrosion protection of the car is within 15 years, which is a sufficient period even for cars in a more expensive price segment.

A piece of paint fell off the fender, the galvanized body is visible, but rust still began to appear

The result of the work done by the Renault concern was not long in coming. Rumors about a new budget and inexpensive car, with a galvanized body, quickly spread among the people and rightfully lost claims about the quality of the coating on the Logans. Few modern automakers can boast of such a result in the field of service and understanding of the problems of their customers.

7 layers of galvanization

Most owners agree that the Renault Logan body is well galvanized and practically not subject to corrosion

When designing the radically changed appearance of the 2nd generation Renault Logan, the designers took a different look at the anti-corrosion treatment of the body.

From 2013 to the present, on Renault conveyors, Logan models are subject to complete body treatment, including hidden cavities, by double-sided galvanizing (combines well with paint and primer) using the method of immersion in a zinc electrolyte under the influence of current.

Rust on a Logan that is less than a year old (under the front right door - under the trim)

With this treatment, the zinc layer is about 9-15 microns. Thus, under normal operating conditions, the first traces of corrosion may appear no earlier than after 10 years of use of the vehicle.

Only numbers!

  • 5-15 microns (micrometers) is the ideal thickness of zinc coating to protect against corrosion on a car.
  • From 1 to 6 microns - this is the rate of destruction of the zinc layer per year when the paintwork is damaged. Destruction occurs more actively at positive temperatures.

Let's sum it up

To sum up all of the above, you can be sure that most P cars Eno Logan on our roads have a galvanized body with a high degree of corrosion protection. Having such a car, you can be prepared for all the troubles of the Russian climate and operating conditions.

Among the disasters that supporters of buying a used, but premium used car predict for buyers of new budget cars, corrosion is a must. They say that before the buyers of public sector employees have time to look around, they will turn from owners of brand new cars into owners of rusty and leaky tin cans. But are there prophets in their own country?

We had to answer this question during an examination of the corrosion state of the 2012 Renault Sandero Stepway. In the same year, the car was purchased new in Minsk, used daily, and traveled 46 thousand km since purchase. According to the owner, the car has driven no more than 2-3 thousand km outside the city. Considering that this is no more than 5% of the total mileage of the car, it can be stated that the test object is used mainly in the city, where in winter road workers spare no expense in combating ice, which is why city operation involves regular “bathing” in metal-aggressive conditions. reagents. At the same time, again according to the owner, Stepway visited car washes about once a month. In general, you couldn’t think of a better object to check.

From the outside, the car looked perfect, but we decided to find out what was going on behind the outer shell while the object of inspection was waiting to enter the lift.

Under the hood, corrosion was found in the niche of the battery, the proximity of which always poses a threat to the metal. The shock absorber strut fasteners also began to rust. That's all, and although the catch is not large, it suggests that other finds should await us.

In the interior, it immediately caught my eye that rust had taken a liking to the seat slides...

... and in the trunk there are fastening parts.


Having searched under the door seals and floor covering, we found small pockets of corrosion in the doorways.

However, the rust has still not touched the lower parts of the doors, and yet these elements constantly appear in the list of places that suffer the most from corrosion in a variety of cars. But now Stepway drives onto a lift, which means you can see what’s happening on the bottom, which is one of the first on the list of body elements, especially those suffering from corrosion.

We note that the bottom is treated with an anti-corrosion agent. True, the protective coating was not applied in a continuous layer, but selectively in places that the person who treated the car considered most vulnerable to rust.

Typically, this is the nature of the factory anti-corrosion treatment. Based on the results of the inspection of the car that was tested by us, we do not recommend that Stepway owners rely on the high durability of the existing protective coating. Cracks were found in the coating in the area where the front stabilizer bar was attached. Their danger lies in the fact that moisture does not disappear from them for a long time, which, having reached the metal, creates conditions for rapid and at the same time imperceptible corrosion.

But we found few obvious spots of rust on the bottom of the Stepway we tested. One of them is directly above the rear suspension beam.

Another was the area around the access hole on the power cross member behind the front suspension.

Rust has also appeared on the suspension parts...

... and spring support cups. Given the damage that corrosion managed to cause to the tested Stepway over 4 years of operation, we were once again convinced of the correctness of the now popular words from the Gospel that there are no prophets in their own country.

However, let's give the prophets one more chance. As you know, the greatest threat to body parts is not external, but internal corrosion in hidden and therefore poorly ventilated cavities. In addition, hidden cavities are difficult to access and troubleshoot. We have an endoscope that will show what is happening in such cavities of the object being examined.

We did not see any corrosion on the endoscope screen. But they discovered that the hidden cavities were also treated with an anti-corrosion agent.

The director of the authorized Krown anti-corrosion treatment center, Alexey Mukhlaev, with whom we carried out the examination, noted that the condition of this Stepway can be called ideal for a four-year-old car that was used daily and only in the city.

But in order for the tested machine to continue to remain in this state, it is advisable to repeat the treatment. This is indicated by the presence of cracks in the old coating, and by the fact that in places subject to sandblasting, the coating is already worn out.

We thank the authorized Krown anti-corrosion treatment center for advice and assistance in photographing

“It won’t rust behind us” - a joint project of the site and the “Authorized anti-corrosion treatment center KROWN . In our materials we will demonstrate corrosion testing of the most popular used cars. Let's talk about the weak points of anti-corrosion treatment of cars that have just rolled off the assembly line. We will advise you on what you need to do to protect the body of your car as much as possible from the red plague.

The Sandero body is ideal for a city car, which has all the capabilities necessary for the fast pace of modern life in a metropolis - it is maximally functional and completely ergonomic. Renault Sandero is a compact, economical hatchback that fits perfectly into the realities of urban traffic. The Sandero's body makes it easy to maneuver even on narrow streets and always find a parking space without any problems.

Sandero body colors

Body color is an important characteristic when choosing a car. A juicy and “tasty” color attracts the buyer’s attention, which naturally increases sales. Therefore, technologists and engineers of automobile concerns strive to offer their potential consumers maximum variety in the choice of body color for each car model. The Renault Sandero car is no exception - it is available in several colors, which significantly expands the possibilities of choice.

Renault Sandero Stepway: body colors 2016

It would be right to start a conversation about the body color of Renault Sandero with cars produced in the not so distant past - namely, with cars that rolled off the assembly line in 2015 and 2016.

This is the so-called second generation Sandero, which, judging by manufacturer reviews, received higher passenger safety characteristics, increased ground clearance, and also underwent some design changes.

As for the colors of the new body, 6 color options are available for the Russian consumer:

  • black pearl (black);
  • golden green onyx;
  • gray platinum (gray);
  • azure (blue);
  • light basalt;
  • red.

The Sandero car also has options in white and orange, but these colors are not yet available in our country. But you can choose a car body coating - gloss or metallic.

The body color of the second generation Renault Sandero Stepway 2015 has become richer, brighter and more modern. By the way, it is often mistakenly called the Sandero body of the 3rd configuration, although in fact it remains the same 2nd generation.

Renault Sandero: old body 2011-2014

Despite the fact that the second generation of the hatchback has already been released, the technical characteristics of Renault Sandero in the old body fully comply with modern requirements. Reviews from owners say that with proper service and timely repairs, a Renault Sandero car will last a long time without causing any complaints.

As for the colors of the old 2014 Sandero body, some of them coincide with the colors of the new body (light basalt). Among the body colors of Sandero 1 are:

  • white ice;
  • light basalt;
  • blue mineral;
  • black Pearl;
  • gray platinum;
  • red bullfighter

Body galvanization

Many car owners are interested in the question: is the Renault Sandero Stepway body galvanized or not?

According to an official representative of the Renault company, both the first and second generation Sandero have a partially galvanized body. The Sandero body is of the zinc-metal type.

During the rolling process of steel body elements, zinc particles are deposited on it. Also during the production process, a layer of oxides containing zinc particles is applied. According to experts, corrosion will begin no earlier than 9 years after the car’s release, that is, for cars produced in 2014 only in 2023, and for the new generation Sandero produced in 2016 – in 2025. Given the fairly low cost of Renault Sandero (or Dacia Sandero), this figure is very impressive.

Renault Sandero: body dimensions

The compact and perfectly adjusted dimensions of Renault Sandero make the car not only comfortable, but also allow you to easily maneuver on city roads. The smooth shape of the Sandero body provides the car with excellent aerodynamic properties. Comfortable and maximally convenient from the inside out, the body has compact dimensions to find spaces in city parking lots even when they are very busy. The length of the Renault Sandero body is just over 4 meters.

Sandero body - technical characteristics:

  • Body length 4.05 m.
  • Body width 1.73 m.
  • Body height 1.51 m.
  • Weight 993 kg (basic configuration).
  • Wheelbase 2.63 m.
  • Ground clearance (ground clearance) 164 mm.
  • Several color options.

Body type Renault Sandero

The Renault Sandero, a popular car in our country, is classified as a city hatchback by its body type. The city hatchback is subcompact, but still has sufficient spaciousness. This body is also called a pre-crossover.

Where is Renault Sandero assembled in a new body?

Renault Sandero in a new body, intended for the Russian market, is assembled in Moscow at the Renault Russia plant. Foreign models are assembled in several countries, with the main production located in Romania. There is a widespread belief among consumers that foreign-assembled cars are of higher quality, while “Russian” versions of the Sandero can have many flaws.

Given the current demand, all Sandero models imported from abroad will not be enough for everyone. At the same time, it is also worth taking into account the rather large duties for the import of foreign-assembled cars. Therefore, consumers have no options left, and they have to buy Sandero “made in Russia”.

To be fair, it is worth noting that Russian-assembled cars undergo the strictest quality control, and the result is almost flawless cars, which is recognized even by foreign engineers. Russian versions of Sandero are adapted for Russian operating conditions and have been performing well for several years now.

By the way, Sanderos assembled in Russia are sent not only to domestic dealers, but also to dealers in the CIS countries.

Sandero body - advantages

  • Stylish design
  • Compact dimensions
  • Capacity
  • Maximum comfort

Galvanization of Renault Sandero body

The table indicates whether the body of the Renault Sandero car, produced from 2009 to 2013, is galvanized,
and quality of processing.
Treatment Type Method Body condition
2009 PartialZinc metal Galvanization result: Acceptable
The car is already 10 years old. Considering the age and quality of zinc treatment of this car (under normal operating conditions), corrosion of the body has just begun. It is difficult to notice if the car has not been subjected to shocks and scratches.
2010 PartialZinc metaldeposition of zinc particles during steel rolling process
applying a layer of oxides containing zinc particles
Galvanization result: Acceptable
The car is already 9 years old. Considering the age and quality of zinc treatment of this car (under normal operating conditions), corrosion of the body has just begun. It is difficult to notice if the car has not been subjected to shocks and scratches.
2011 PartialZinc metaldeposition of zinc particles during steel rolling process
applying a layer of oxides containing zinc particles
Galvanization result: Acceptable
The machine is already 8 years old. Considering the age and quality of zinc treatment of this machine (under normal operating conditions), the first corrosion will begin in 1 year.
2012 PartialZinc metaldeposition of zinc particles during steel rolling process
applying a layer of oxides containing zinc particles
Galvanization result: Acceptable
The machine is already 7 years old. Considering the age and quality of zinc treatment of this machine (under normal operating conditions), the first corrosion will begin in 2 years.
2013 PartialZinc metaldeposition of zinc particles during steel rolling process
applying a layer of oxides containing zinc particles
Galvanization result: Acceptable
The machine is already 6 years old. Considering the age and quality of zinc treatment of this machine (under normal operating conditions), the first corrosion will begin after 3 years.
If the galvanized body is damaged, corrosion destroys zinc and not steel.
Types of processing
Over the years, the processing process itself has changed. A younger car - Galvanized will always be better! Types of galvanization
The presence of zinc particles in the soil covering the body does not affect its protection and is used by the manufacturer for the word “galvanization” in advertising materials. . Tests Test results of cars that came off the assembly line with the same damage (a cross) on the lower part of the front right door. Tests were carried out in the laboratory. Conditions in a chamber with hot salt fog for 40 days correspond to 5 years of normal operation. Hot dip galvanized vehicle(layer thickness 12-15 microns)
Galvanized car(layer thickness 5-10 microns)

Cold galvanized vehicle(layer thickness 10 µm)
Car with zinc metal
Car without galvanization
It is important to know— Over the years, manufacturers have improved the galvanizing technology of their cars. A younger car will always be better galvanized! — Thick coating from 2 to 10 µm(micrometers) provides excellent protection against the occurrence and spread of corrosion damage. — The rate of destruction of the active zinc layer at the site of body damage is from 1 to 6 microns per year. Zinc degrades more actively at elevated temperatures. — If the manufacturer uses the term “galvanization” "full" not added This means that only elements exposed to impacts were processed. — Pay more attention to the presence of a manufacturer’s warranty on the body rather than loud phrases about galvanizing from advertising. Additionally
