If the galvanized body is damaged, corrosion destroys zinc and not steel.
Types of processing
Over the years, the process itself has changed. The car is younger - will always be galvanized better! Galvanized types
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 "galvanized" in advertising materials. ... Testing Test results of vehicles rolled off the assembly line with the same damage (cross) on the lower part of the front right door. The tests were carried out in the laboratory. Conditions in a hot salt spray chamber for 40 days correspond to 5 years of normal operation. Hot Dipped Galvanized Vehicle(layer thickness 12-15 microns)
Galvanized vehicle(layer thickness 5-10 microns)

Cold galvanized car(layer thickness 10 microns)
Car with zinc metal
Vehicle without galvanizing
It's important to know- Over the years, manufacturers have improved the technology of galvanizing their cars. A younger car will always be better galvanized! - Coating thickness from 2 to 10 microns(micrometers) provides excellent protection against the occurrence and spread of corrosive attacks. - The rate of destruction of the active zinc layer, in the place of damage to the body, is from 1 to 6 microns per year... Zinc is more actively destroyed at elevated temperatures. - If the manufacturer has the term "galvanized" not added "full" this means that only the elements subject to impacts have been processed. - Pay more attention to the presence of the manufacturer's warranty on the body, rather than loud phrases about galvanizing from advertising.

Renault Sandero is a compact budget class car, produced since 2007, produced in the back of a five-door hatchback. This car is inexpensive, and also does not cost the budget and vehicle maintenance. Outwardly, Sandero resembles Renault Logan, but the hatchback design is more attractive.

For the first time, the French model was presented in Brazil, and a little later it was 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 built 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 are borrowed from the Logan, so 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

On Renault Sandero, the body is galvanized, the body iron itself is strong enough. These cars rarely rust, mainly corrosion occurs if the car has been in an accident. The paintwork of the body is not bad, chips first of all appear on the wheel arches, in the area of ​​the sills.

What are the disadvantages of engines

There are no powerful engines in the Sandero powertrain lineup, and you can't count on sportiness here. The most popular is the 1.4-liter four-cylinder engine with 72 or 75 horsepower (8 valves).

Also, an internal combustion engine of 1.6 liters is installed on the car in two modifications:

16-valve - 84 HP with.;

8-valve - 106 HP with.

The 1.4 liter engine is somewhat weak, its thrust is not enough for a relatively heavy car. Often this motor works at its limit, and from the load power unit resource decreases markedly. 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 16-cl. It is recommended to change the internal combustion engine of the K4M model every 60 thousand kilometers; it is better to replace the parts of the gas distribution mechanism with a set (belt, water pump, tension rollers).

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

The gasoline engines installed on the Sandero are quite reliable, but they still have some problems. One of the characteristic "diseases"- jamming of the thermostat, with such a defect, the motor may overheat or, conversely, operate in a low temperature mode. Not too long "live" candles and high voltage wires, they often punch to the ground from dampness.

Sandero gasoline engines have a very good resource, with proper care and careful operation serve 500 thousand km and more before overhaul.

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 1.6-liter 16-valve engine, the "mechanics" is installed together with an 8-valve engine.

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

Oil change in the "mechanics" by the manufacturer is not provided, the lubricant should be enough for the entire service life of the gearbox. But if the transmission already covered 100 thousand km, it is better to replace the oil in the unit, it will not be worse from this.

Four-speed "automatic machines" are not famous for their special reliability, automatic transmissions are mainly fail due to overheating... The automatic transmission often requires repairs on a mileage of about one hundred thousand kilometers; the oil in an automatic transmission should be changed after 50 thousand kilometers.

Suspension and suspension sores

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

First on Renault Sandero Bushings and stabilizer struts "give up", they serve on average 50-60 thousand km. Rear and front shock absorbers are sensitive to the quality of the road surface, they begin to leak quickly if the car is often used on a bad road. But in any case, the resource of these parts is at least forty thousand kilometers, the original shock absorbers last longer (70-80 thousand km each).

Steering rack not too "tenacious", first of all the plastic sleeve wears out. The manufacturer did not provide repair kits for the rail, but the parts can be supplied from another car model, for example, from BMW. Before you repair the steering mechanism, you should check the backlash in the tips and rods, the resource of which is 60-70 thousand km.

Life time front brake pads are standard - an average of about 30-40 thousand km. If the front caliper rails are lubricated, the pads can last longer, and the life of the parts also largely depends on the driving style.

Vehicle interior

The interior of 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 very high quality, but "Sandero" still belongs to the budget class, and therefore you should not expect the best from the interior trim.

Here is what the RENAULT hotline answered

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, before the buyers of "state employees" have time to look back, they will turn from owners of brand new cars into owners of rusty and leaky cans. But are there prophets in their own country?

We had to answer this question during the examination of the corrosion state of the 2012 Renault Sandero Stepway. In the same year, the car was bought new in Minsk, it was operated every day, drove 46 thousand km from the moment of purchase. According to the owner, the car drove 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 object of inspection is used mainly in the city, where in winter road workers spare no money to fight ice, which is why urban operation involves regular "bathing" in aggressive metal reagents. At the same time, again, according to the owner, Stepway visited car wash approximately once a month. In general, you cannot imagine a better object for verification.

From the outside, the car looked perfect, and what is being done behind the outer shell, we decided to find out while the test object was waiting for the lift.

Under the hood, corrosion was found in a battery niche, the neighborhood with which is always fraught with a threat to metal. The shock absorber struts have also begun to rust. That's all, and although the catch is not rich, it suggests that other finds should await us.

In the cabin, it immediately struck the eye that rust had taken a fancy to the seat sleds ...

… And in the trunk there are fastening parts.

Searching under the door seals and floor covering, we found small foci of corrosion in the doorways.

However, rust has not yet touched the lower parts of the doors, and it is these elements that constantly appear in the list of places that get the most from corrosion in a variety of cars. But Stepway drives into the lift, which means that you can see what is being done on the bottom, which is one of the first in 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 car operator considered the most vulnerable to rust.

Usually this is the nature of the factory anti-corrosion treatment. Based on the results of the inspection of the machine, which has passed our examination, we do not recommend Stepway owners to rely on the high durability of the existing protective coating. Cracks were found on the coating in the area where the front anti-roll 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 foci of rust at the bottom of the checked Stepway. One of them is directly above the rear suspension beam.

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

Rust also appeared on suspension parts ...

... and the spring cups. With the damage that the tested Stepway managed to inflict over 4 years of operation, we once again became convinced of the correctness of the words from the Gospel that have become winged words, that there are no prophets in our homeland.

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

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

Alexey Mukhlaev, director of the authorized center for anti-corrosion treatment Krown, with whom we carried out the examination, noticed 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 checked machine to continue to remain in this state, it is advisable to repeat the processing. This is indicated by the presence of cracks in the old coating, and the fact that in places subject to "sandblasting", the coating is already worn out.
