What machine is on the Hyundai Solaris: robot or automatic transmission? Examples of recent work

Since 2010, Hyundai Solaris has been equipped with 1.4 and 1.6 liter gasoline engines. At first it was G4FA and G4FC, later G4LC. Their power ranges from 100 to 123 horsepower. The engines are paired with a manual or automatic transmission. The first mechanics on Solaris marked M5CF1 had 5 steps and was made on the basis of a two-shaft scheme, a few years after the start of production, a six-speed mechanics M6CF1 became available. As for the machine, the Korean manufacturer initially used the A4CF1 four-speed automatic transmission. After restyling in 2014, a six-speed automatic was developed for versions with a 1.6-liter engine, but the A4CF1 box is still available for the Hyundai Solaris with a 1.4-liter engine.

Technical features of Hyundai Solaris engines

The Gamma series of motors, developed for the Hyundai Solaris and other models of the concern, has replaced the Alpha series and has characteristic features:

The cylinder block is cast from aluminium, lightweight construction has high rigidity. To prevent the cylinder from being worn out by the piston, a thin cast-iron sleeve is used, which is fused into the part. This arrangement allows you to reduce the weight of the motor, to achieve rapid warm-up and efficient cooling of the power plant. At the same time, fuel consumption drops.
The manifolds are designed on the basis of the reverse scheme: the catalyst and exhaust manifold are located between the engine shield and the engine itself, while the intake manifold is located in front. This scheme made it possible to increase power, simplify maintenance, and repair the injection system.
The timing chain uses a chain that is prevented from stretching by hydraulic tensioners.
A system has been introduced that changes the valve timing, which improves the traction of the car.
There are no hydraulic lifters.
Mounted units, in particular the generator, power steering pump, air conditioning compressor, are located more competently than in the Alpha series engines.

Structurally, the G4FC and G4FA motors, despite the different volumes, are similar. A chain was used as a drive for the gas distribution mechanism, which runs 150–180 thousand km without problems. Every 100 thousand km it is recommended to adjust the valves. These Solaris engines are unpretentious and economical. Although quite noisy, especially until they warm up.

The resource of the Solaris engine depends on standard factors: quality of service, driving style, compliance with operating standards. The manufacturer issues a guarantee for a car - 150 thousand km. But Hyundai Solaris power units run 200-300 thousand km without problems. And what after? Requires repair afterwards. And since the block is made of aluminum, it can be considered "disposable", that is, after the wear of the cylinders, it must be replaced.

There are workshops in Russia that have developed their own recovery methods, but the fact remains: there are no strictly verified factory repair technologies, engineers created a lightweight, high-tech cylinder block, sacrificing its maintainability.

Then what do the motorists do? They bore blocks, grind crankshafts and cylinder heads, extract and change cast-iron liners. But the difficulty lies in the fact that the wall of the sleeve is very thin, and it itself is “filled” with aluminum - it is fused into the block. And in view of the fact that the strength, corrosion resistance, hardness of aluminum and cast iron are different, it is necessary to carry out other, more subtle repair operations that not every master can do.

Therefore, it makes sense to strictly observe maintenance standards, change the oil and oil filter every 7.5–10 thousand km (the manufacturer recommends Shell Helix 5W40), and additionally use CIP and flushing, which will extend the life of the power unit. It is advisable to do the treatment with a repair and restoration compound before the characteristic signs of malfunctions of the Solaris engine appear:

Compression drop.
Engine vibration and speed fluctuations.
Increased oil consumption.
Strong noise due to wear of the crankshaft, elements of the cylinder-piston group.

What will the in-place repair of the Solaris engine give?

The RVS-Master additive is a friction geomodifier that restores worn parts by building up a layer of cermet. This happens only where the reaction of substitution of Fe atoms by Mg atoms is possible. In Hyundai Solaris engines, a layer of cermet is formed on cast-iron liners. The rest of the aluminum surfaces are cleaned of carbon deposits. Engine processing gives the following results:

Life extension (this is critically important for the Hyundai Solaris engine, the restoration of which is technically difficult, and not every master is ready to give a guarantee on the result of the work done).
Increasing the elasticity of rubber seals, which minimizes oil leakage.
Reduced fuel consumption - up to 15%.
Minimization of noise and vibrations of the Hyundai Solaris engine.
Simplification of start-up at sub-zero temperatures.

An additive is suitable for processing a Solaris engine with a volume of 1.6 liters, since this engine has 3.7 liters of oil. A similar composition will be needed for a 1.4-liter engine, in the lubrication system of which there are 3.3 liters of oil.

Pay attention to the intensive use of Hyundai Solaris, you should combine the scheduled oil change with flushing the system with an additive. This is especially true in cases where the car is operated in a metropolis with frequent downtime in traffic jams. Flushing will remove soot and other deposits from the internal surfaces of the power unit.

If your Solaris has unexpected malfunctions in the operation of candles or the ignition coil has failed, you should be more careful when choosing a gas station.

Most likely, you refueled with low-quality gasoline. To continue to protect yourself from similar consequences, use an additive. It will increase the octane index of gasoline by 3-5 units, optimize the combustion process, and reduce the likelihood of freezing.

Manual and automatic transmission Hyundai Solaris

For Hyundai Solaris, classic mechanics and automatic are available. The car was equipped with two different automatic transmissions: four- and six-speed. Moreover, the six-speed gearbox marked A6GF1 is more economical, pleases with smooth operation, but upsets with a mediocre reaction to pressing the gas pedal. The A6GF1 holds 7.3 to 7.8 liters of ATF.

Although the plant does not provide for changing the oil in automatic transmissions, this should be done every 80–100 thousand km. After all, the A6GF1 box is sensitive to the quality and pressure of the oil, the integrity of the seals, gaskets. If you neglect maintenance, critical wear is likely, failure of solenoids, clutches. The additive will help restore the automatic gearbox and prevent its wear.

The five- and six-speed manual gearboxes of the Hyundai Solaris are quite reliable, which is confirmed by the experience of their operation on the Elantra and other Korean models. Among the factory shortcomings of the five-step machine is increased noise, a rumble when reversing. The defect appeared on cars manufactured before 2012.

In mechanical transmissions, we recommend changing the oil every 50-60 thousand km. And to extend the life of the box, use . Thanks to the additive, it will be possible to extend the life of parts, compensate for wear on friction surfaces, achieve easier shifting, reduce transmission noise and restore gears.

EXAMPLES OF RECENT WORK

In the event of a major overhaul, the gearbox is dismantled from the vehicle. At this stage, the mechanic carefully inspects the condition of all systems serving the gearbox, power unit mounting supports, etc.

After dismantling from the car, the automatic transmission enters the overhaul site. It should be noted that in this section, as well as in all the previous ones, experienced craftsmen who have a higher technical education (engineering and physics) work. Here, the automatic transmission of the Hyundai Solaris is being repaired, and after washing and drying all the parts, their fault detection is carried out, i.e. the possibility of further use of each part or the need to replace it is determined.

If desired, any customer can be present both during the disassembly of the gearbox and during the inspection of its parts. At the end of this procedure, a list of replacement parts is compiled, which is then necessarily agreed with the customer. It should be especially noted that during the overhaul, it is necessary, regardless of the condition of the automatic transmission, to replace all seals and gaskets. The use of original spare parts only from gearbox manufacturers increases the service life of the repaired Hyundai Solaris automatic transmission, but leads to a significant increase in the cost of spare parts. To achieve the most optimal combination of “price-quality” ratio allows the use of “aftermarket” parts, i.e. companies specializing in the production of spare parts for automatic transmissions.

Installation is made taking into account all technical requirements. At this stage, the failed fastening elements and auxiliary transmission maintenance systems are replaced. In addition, during installation, preliminary adjustments are made to the elements of the external part of the control system.

Output diagnostics and running-in of the car. They are carried out according to the same methods as the input diagnostics. In addition, all previously appeared fault codes are erased from the memory of the control unit.

The correct operation of the transmission in any machine depends on the quality of the lubrication of the rubbing components inside the unit. If the fluid loses its properties, it cannot perform its functions, as a result of which the gearbox begins to work intermittently. To prevent this, Hyundai Solaris must be replaced in a timely manner.

Replacement frequency

Many car owners are interested in when and after how much the consumables are changed in the transmission of Hyundai Solaris 2011, 2012, 2014 and other years of production. Therefore, to begin with, we will analyze at what mileage it is necessary to change the lubricant in the gearbox. According to official data, the oil for the Solaris automatic transmission does not change. The manufacturer fills the liquid for the entire service life of the car. But in fact, the lubricant is produced over time, loses its characteristics and cannot perform the functions assigned to it, that is, it does not provide proper lubrication of the unit. In practice, the change of transmission consumables in a Hyundai Solaris car with a gasoline engine should be carried out every 50-60 thousand kilometers. Experts advise to perform this procedure once every two years.

The interior of the automatic transmission

There are several important factors that affect the service life of a fluid:

temperature fluctuations. When the air temperature changes frequently, this leads to a change in the viscosity characteristics of the oil. If the drops are too sharp, this causes a loss in the technical characteristics of the lubricant.
Continuous operation of the car in start-stop mode. For example, a car is used in traffic jams in a big city.
driving style. If the driver frequently shifts gears, brakes hard or starts to move, an additional load is placed on the lubricant. Because of this, the lubricant becomes contaminated faster and its work becomes less effective.

What "symptoms" can indicate the need to change the oil in a Hyundai Solaris automatic gearbox:

the appearance of sediment and wear products in the consumable;
the presence of a burning smell;
the appearance of difficulties when activating a particular transmission;
the presence of vibrations in the area of \u200b\u200bthe automatic transmission switch selector;
the appearance of extraneous sounds during the operation of the unit;
transmission began to kick and push.

Which oil is better to choose?

Original product for automatic transmission Solaris

It is important for the driver to know what liquid should be poured into the unit. The manufacturer Hyundai recommends that consumers fill the system with the original ATF SP 3 product, which is manufactured by the concern. This oil allows you to optimally perform the function of lubricating rubbing components, as well as to ensure cooling of the components and high-quality flushing of all parts. When using the original product, you can achieve optimal torque transmission. As for the degree of viscosity, it is better to choose a consumable that belongs to a lower class. For example, all-weather oils should have an index of 90W, 140W, and winter fluids - 75W, 80W or 85W.

Level control and topping up

To diagnose the fluid level, you need a white napkin:

Start the car engine and drive for 10 minutes to warm up the transmission.
The level check is carried out on a level surface. Stop the engine and wait about ten minutes for the transmission fluid to drain into the sump.
Open the hood and locate the dipstick to check the level. It is located on the right in the engine compartment.
Wipe the dipstick with a napkin and reinstall it in the hole, then remove it. If the fluid level is normal, then it will be located between the two marks on the dipstick.

The service station channel in Simferopol published a video demonstrating the procedure for changing the lubricant in the Solaris automatic transmission.

How to change engine oil with your own hands?

You can change the oil in a 4-, 5- or 6-speed automatic gearbox on Solaris with your own hands, without the help of specialists.

Training

To complete the task you will need:

new lubricant;
funnel or cut off top of the bottle;
rags;
syringe with connected hose;
a bucket or basin into which the lubricant will drain.

Partial replacement

Partial lubricant change is an easier and more economical way to change the oil.

This procedure is performed every 20-30 thousand kilometers. But keep in mind that with a partial replacement, only about a third of the liquid can be drained from the system, no more. It is necessary to dismantle the pan, so you can additionally replace the filter device. The main disadvantage is that fresh grease will mix with used grease, and this will not improve the performance of the transmission as a whole. Therefore, if the oil used in the gearbox is of poor quality, and there are problems in the operation of the unit, then a partial replacement is not suitable for you.

The procedure is performed like this:

First, open the hood of the machine and check the fluid level in the system.
For incomplete replacement, start the engine for a few minutes. The automatic transmission selector with the engine running must be moved in all positions, stop for a few seconds in each gear.
One end of the hose connected to the syringe must be installed in the control hole and about 25-40% of the lubricant should be pumped out of it.
Then, using the same syringe, pour fresh grease into it and fill the gearbox with it.

The procedure for partial and complete replacement is clearly shown in the video shot by the Hyundai Solaris channel.

Complete replacement

The most effective way to completely change the lubricant in the transmission is with the help of specialized equipment that can be found at the service station. But if you decide to do everything yourself, you can do without it.

How to make a replacement:

Check lubricant level. This is done in order to understand how much oil is left in the system. If the fluid level is low, check all components of the transmission system for leaks.
Get under the bottom of the car. Locate the drain plug and place a bucket or basin under it to collect the used grease. When draining, the dipstick must be removed from the control hole to reduce the pressure in the gearbox housing and speed up the procedure.
Wait until all grease has completely drained from the transmission unit. Then the drain plug must be closed.
Install a funnel in the level hole and pour new grease into the automatic transmission through it.
Remove the funnel from the control hole, insert the probe into it and start the power unit for 5 minutes. With the engine running, it is necessary to turn on all the modes of operation of the gearbox in turn, on each of which a 10-second pause should be maintained. These actions will allow you to disperse the lubricant through all channels of the system and partially flush it from the remnants of the waste fluid. Thanks to the circulation of oil, all wear products can be removed from the gearbox.
Open the drain plug and drain the grease. Appreciate its quality. If wear products and deposits remain in the oil, the flushing procedure must be repeated. Fill with oil up to the maximum mark and tighten the plug.
Start the power unit. Use the gear selector to activate all modes of the transmission. Drain the lubricant and if its quality has improved, then fill in new oil according to the level. Perform a test drive. Check the fluid level in the system again and add oil if necessary.
