Volkswagen Polo Sedan Gram. The process of replacing the timing chain Volkswagen Polo

Rides with a worn drive chain of the gas distribution mechanism threaten serious consequences. Unlike the belt, the chain can not break, but it is capable of jumping due to stretching. In this case, there will be great damage to the design power plant. To restore performance, the power unit will be required by overhaul. To avoid unprofitable trouble, you need to change in a timely manner timing chain on Volkswagen Polo Sedan 1.6.

Periodicity of service

According to the rules of the German automaker, the detail of the mechanism does not require replacement during the entire period of operation, if it is proper. Installation of the new chain is needed only when it is malfunction.

Unfortunately, the quality of roads and others negative factors Cause problems even with the most eternal mechanisms. The drive component is stretched as a result of exposure to high loads, aggressive driving style, the use of low-quality components, etc. Consequences of work under such conditions a change in the distance between the teeth, the slipforms of the chain, the violation of the timing and the engine breakdown.

Why the chains are premature to produce the laid resource

1. Due to the imperfection of the design. Engines of world autocontracens, and VAG in particular, are famous for their constructive disadvantages, leading to accelerated wear chains.
2. As a result of the use of low-quality fuels. The incorrect lubricant of the participants in the mechanism contributes to the accelerated abrasion of contacting elements.
3. Due to the frequent operation of the engine on idling. Operation in the city with traffic jams frequent cause The need to replace the timing chain.
4. Aggressive driving with an immentable motor. Sharp large load on the engine at minus temperature ambient Devil for participants of the gas distribution mechanism.

Signs of the chain fault Volkswagen Polo sedan 1.6 CFNA and CFNB

On unsatisfactory state parts will be spare parts for the following symptoms:

• Difficulties with the launch of DVS
• The appearance of extraneous noise, knocking, rattling with the engine running
• Unreasonable turning of fuel
• Pass ignition
• Worsening dynamics during acceleration
• Drop power engine
• Salmon light bulbs signaling about the error of the DVS operation.

These features may indicate other component faults. automotive system. To determine the state of the chain you need to hold computer diagnostic Engine Volkswagen Polo. Due to late appeal to the service, the risk of expensive replacement of the node assembly increases.

Employees of Russian dealers are recommended to replace the VW Polo Sedan chain when a run of 80-90 thousand km is reached. It is by this time that problems with the detail of the phase displacement begin to appear, which causes a drop in performance by 20-40 hp

Advantages of the timing chain in front of the belt

The chain drive, which has the Volkswagen Polo Sedan model in Russia, has a number of advantages over the belt transmission:

• Strength is not inclined to mechanical damage
• Wear Resistance Resource reaches 100 and more than a thousand km run
• Resistance to temperature drops The chain does not change the characteristics at no, nor at high temperatures
• Stability K. different types loads chain does not break due to impact and vibratory influences
• Resistance to local overloads.

Spare parts for replacement

The choice of components for servicing the gas distribution mechanism is better to entrust the competent consultant. When replacing the timing chain german car A number of related spare parts are applied with a 1.6-liter engine: tensioner, calm, seals, sealing rings. For the convenience of car owners there are kits for replacing the main chain, in which parts are collected corresponding to a certain configuration of the car. It is not recommended to buy products of third-party manufacturers and select positions on the coincidence of external signs.

Original VAG components for GRM Sedan Volkswagen Polo 1.4TSI and 1.6MPI have the following catalog numbers:

• 03c109507ba tensioner
• 03C109469 and 03C109509 Soothing
• 038103085E crankshaft seal

The price of a set, taking into account the discount in the official online store of auto parts in Moscow, am-paroles is 6900 rubles (as of November 2018). Corporate details are also used for engines of others. volkswagen models (Passat, Golf, Jetta, Sirocco, Turan), Skoda and Audi.

How to maintain chain performance

• Periodically check the condition of the chain and related elements
• Listen to the operation of the motor, especially when starting
• Follow the rules for servicing the oil system.

With proper operation, service and repair, the risk of the timing of the timing chain is eliminated.

The chain of the gas distribution mechanism of the engine is "infinite", "troubleshoot", "armorboy" - epithets in its justification of thousands and all only positive. Of course, any seller of cars will tell you - yes there is a chain, then you can "not steam away" about replacements in 100 - 120,000 kilometers, bought and what they say - forgot! But is it really if it really is not the stepping, and in the end, what is her resource? Let's deal with ...

What to say the chain is definitely better than the belt, in reliability, it is no matter how competitive. After all, all elements are made of metal and it is known, much more reliable than rubber, plastic and tissue threads in the belt structure.

Why don't some manufacturers put a chain?

Now, it seems like, the question hangs - why some manufacturers do not install them, but make straps? After all, not practical?

There are several answers:

• This is noise. No matter how cool, but even the perfectly tuned engine with a chain works anyway no more than with a belt. Well, try rolling on the asphalt metal links and rubber - you will understand that no more.

• Constructive feature. The fact is that some engines, in favor of silence, can not use the "metal fellow", because the belt transmission is located outside the engine, that is, it rotates in the air. And so just take and fasten the metal links will not work.
• There are belief that the belt is better capturing the gears of shafts, both distribution and crankshaft. After all, the gear really has wide strips for engagement, but the chain go to the teeth, and even in the oil! No, they are also very effectively entering the hook, and they usually have two rows. But how to assure some manufacturers, they can jump much faster through the tooth than the belt.

• Well, actually the last - tension. Stay the chain mechanism is more complicated than the belt. After all, the belt is easily lightdown, and is again in the air. But the opponent is inside in oil, and it is more difficult to pull it - you will not bend it!

Some write that another chain mechanism is harder to change, because it is really necessary to disassemble almost a half-wing, but the belt, unscrewed the casing, took off and quickly put another! There is some truth in this, that's just a belt in any case, you will change more often than the chain.

About engine maintenance

To begin with, I want to say - that the condition of the oil is very influenced by the chain resource. It is inside, so the better it is lubricated - the resource will grow much. Also indirectly frequent replacement, Carries out of the engine from the engine, every garbage type of sand, dirt, etc., which splits and wear out a chain mechanism, because the sand can penetrate anywhere, including in the connecting links. New oil makes it better to slide the pistons, which removes an excessive load on the chain mechanism.

In general, the result is such - to raise the resource, you just need to change the oil more often, at least 1000 kilometers, but before the term. That is, the dealer states 15000 - change after 13 - 14000, and ideally after 10,000, then the chain will serve much longer.

Ordinary engines

You know, I caught myself thinking that I had no information about anywhere - after how much change the chain mechanism. That is, if you take a plain car, with a conventional atmospheric engine (not a turbo - about it is slightly lower), the resource is often not limited to the manufacturer!

However, you can find such information:

Through the big mileage, about 150 - 200,000 kilometers, it is worth listening to the operation of the engine, whether there is excessive beating and noise. If manifests itself, you need to diagnose the chain and if necessary to change.

That is, the main diagnosis on the sound, and not through a certain mileage. Therefore, the resource varies from the manufacturer to the manufacturer, and from the owner is the owner.

However, if you sweep the numbers, it turns out:

C regard to long then (approximately 15,000 and more)

The chain serves about 150 - 170,000 kilometers.

Taking into account the short then (approximately 10 - 13000 km)

The chain can walk from 300 to 350,000 kilometers.

If you take care of the machine, then a really chain mechanism is the last thing you change! But wait, my friend changed in 15 - 20000, what's the trick? Yes, nothing, just at your friend's engine from Volkswagen, that is, the turbocharged, and even weak, the volume is 1.2 - 1.4 liters.

Turbated engines

There are completely different laws, turbocharged engines have a much larger torque and effort, respectively more horsepower!

Therefore, it is not surprising - that the chain mechanism has a much less resource, the chain is simply pulled out. Then jumps onto the tooth - the engine does not work normally - consumes a lot of fuel, it starts to told, does not pull, or does not start at all.

And manifests itself by weak engines, for example, such as 1.2 - 1.4 TSI. There was a structural error, the width of the metal is tight - narrow.

Now think about the figures, what VAG the owners please (true, unofficially):

Engine 1.2 TSI - replacement after 30000

Engine 1.4 TSI (122 hp) - 80000

Engine 1.8 - 2.0 TSI - 120000

That is, call such runs big - the language does not turn! However, just imagine how the timing belt would work in such conditions, would it generally wear out after 10,000?

If you bring the average figures on turbo engines:

The resource of the chain is about 120 - 150,000 kilometers. However, you need to read the regulations, for some manufacturers they are tightly spelled out.

Functional design belt timing

Replacing the timing belt is part of the planned maintenance car Volkswagen Polo. and plays an important role in the engine vehicle. Unreasonable replacement The belt can lead to a crash in the operation of the motor, and the breakdown to the deformation of the valve of the gas distribution mechanism and the need for overhaul Engine.

All parts of the gas distribution mechanism are closely connected with each other, the injection of air fuel mixes Moves the engine cylinder piston, which in turn pushes crankshaftassociated with a drive belt with switchgear. Thus, the camshaft movement occurs, which adjusts the frequency of the valve movement. The timing belt Volkswagen Polo connects between the gears and transmits the torque from the crankshaft to the distribution, affecting the speed of its rotation. With the service life, the frequency of their revolutions should be equal to.

Types of timing belt

1. Wearing a timing belt leads to a change in the force of transmission of torque from the crankshaft to the distribution, as a result, the frequency of movement of the pistons and engine valves is changed. This in turn leads to a failure in the work of the gas distribution system, rapidly heating the engine and as a result, reducing the power of the motor and the increase in the consumption of the fuel mixture. For reliable and uninterrupted operation of the motor, it is necessary that the valves are closed and opened in one frequency with the pistons of the engine. If due to wear, the timing belt arises, it can cause cliff.
2. Voice of the timing belt Volkswagen Polo - is the most dangerous for the engine damage. In case of such a malfunction camshaft ceases to be associated with crankshaft And it can stop completely arbitrarily in such a position, in which any of the valves of the gas distribution mechanism will be opened. In this case, the piston, moving up, can encounter the valve, which will lead to its deformation. In this case, the car engine faces serious repairs. It should be noted that the scope of the timing belt does not occur unexpectedly, it is almost always accompanied by changes in the engine of the car engine, a decrease in its power, changing the consumption of gasoline, the emergence of foreign pisc, creak, etc.

To prevent and prevent the operation of the gas distribution mechanism, it is necessary to periodically replace the timing belt, it will save the motor car Volkswagen. Polo from breakage, preserving premature engine wear and increase its life.

Causes and assessment of belt wear

Timing belt wear occurs for a number of reasons, avoiding which you can extend the service life of the car engine.

To prevent the complete wear of the timing belt, it is necessary to periodically, with visual inspection of the gas distribution mechanism, check the presence of damage on the belt surface. To inspect and evaluate the belt drive, you must unscrew and remove the protective mechanism cover under which the engine is hidden. The first signs of wear is:

• the appearance of oil and antifreeze inclusions capable of chemical method to destroy the timing belt, with prolonged exposure;
• the occurrence of longitudinal cracks on the rear surface of the belt;
• the formation of transverse cracks on the inner surface of the drive belt;
• the defective surface and the impaired integrity of the region is also a sign of wear;
• the belt is also evidenced by rubber dust on the surface of the part;
• if the timing belt teeth began to flap, or stitched, the item is subject to immediate replacement to a new one.

Signs of timing belt fault

1. Increased consumption of gasoline by car
2. The engine power decreased
3. Full stop of the car on the go, when trying to start the motor does not start, and the starter rotates easier than the usual
4. Unstable engine work at idle and in motion;
5. The emergence of shots in the injector and exhaust pipe

All these malfunctions may indicate the shifting of the phases of the gas distribution and weakening of the belt tension. If you have noticed one or more signs and this list in your Volkswagen Polo car - contact a hundred immediately for inspection.

How often it is necessary to replace the timing belt Volkswagen Polo

Frequency of replacement of any supplies For cars depends on driving style and vehicle operation mode. With an extreme style driving and aggressive use of the vehicle, it is necessary to replace the timing belt, as it is worn and erasing the teeth.

Under normal operating conditions, it is necessary to replace the original timing belt in scheduled mode, every 60 - 70,000 km. Run. During this period, it produces its resource and comes in disrepair. If an analog belt is installed on your Volkswagen Polo car, the replacement must be performed a little earlier than the deadline recommended by the vehicle manufacturer.

What timing belt is better to choose

Modern belts for the gas distribution system are a high-tech product that is characterized by increased strength and wear resistance capable of withstanding high dynamic loads. The timing belts are made of neoprene or polychlorprene with the amplification of sturdy cord fiberglass, nylon and cotton.

1. To avoid the error related to the purchase of the timing belt, refer to the specialists who will help the Win Code of your car to order the timing belt, suitable for the engine of your car. This item is one of the most important in the design of the motor, the slightest deviation in length, width, form and size of teeth can lead to problems in the engine Volkswagen Polo engine.
2. Do not try to save when buying a timing belt, a cheap product can be a poor-quality fake, which will quickly come into disrepair and in the future can cause serious engine breakdown. The best option For any car are original parts, the cost is higher than the analog, but during the operation of the car they quickly pay off.
3. When buying a timing belt, check it on rigidity, good belt Must be elastic and easily bent. The worse the belt, the more harsh it will be.
4. It is not allowed on the belt of the teeth, the pores, pores are signs of a poor-quality belt, which will quickly come into disrepair. The surface of the product should be smooth, small burrs are allowed.
5. For independent purchase Check the timing belt articula, applied on the back, it must match the car code. If the ability to compare the belt code and the car is not, then it is necessary to produce visual comparison Old and new belt, they must be completely identical.
6. To avoid buying fakes, try to acquire spare parts only from official, proven dealers.
7. Do not save on a qualified replacement of the timing belt, contact our certified car service, where competent mechanics will help with the repair of Volkswagen Polo car. And in the store of spare parts you can buy original spare parts for your car.

Timing chain Volkswagen Polo car possesses high reliability and durability. Despite this during operation, it takes place. This leads to a small phase shift, which is reflected in the engine power not for the better.

The original chain of the vehicle vehicle car Volkswagen Polo sedan with a 1.6 liter engine has an articial number VAG 03C109158A. Its price is about 5,200 rubles.

Best alternative option It is the Borsehung chain with a Catalog number B16301. Its cost is about 1,200 rubles. For its quality, it is not inferior to the original. Others good analogues Led in the table below.

Determining the need for replacement

The official manufacturer declares that the Volkswagen Polo drive chain resource is designed for the entire service life of the car. Dealers argue that changing the elements of the drive of the gas distribution mechanism is required when a run is reached about 180-200 thousand km.

Experienced car owners recommend replacing the chain when running 90-120 thousand km. This is not connected with the end of its resource, but with a stretch. As a result, a small phase displacement occurs, causing a drop in power to 20-40 horsepower.

Symptoms of the need to replace the gas distribution mechanism of the Volkswagen Polo mechanism are:

• extraneous knocks when operating the engine, emanating from under the Timing Timeline Cover;
• increased fuel consumption;
• reduction of power;
• the engine periodically stalls;
• cotton in the intake and exhaust manifold;
• instability of the motor at the cold and under load;
• there are difficulties with the launch of the power unit.

• Unscrew two tensioner mounting bolts.
• Remove the tensioner.
• Remove the tensioner's shoe.
• Remove the chain from stars.

• Machine in reverse sequence. It is necessary to strictly monitor the position of the tags.

Mounted chain timing

On the Volkswagen polo machines, several engines are used. When a 1.6 l motor is installed on the sedan polo, the timing chain changes on the drive. On the engine with the volume of 1.4 liters is used belt. So as not to be mistaken in the drive, just look at motor compartment. In the case of the installed belt, there will be a plastic casing on it, if the drive is a chain, then it will be protected by a metal housing.

Official timing producer

We need to timely replace the timing of timing on the VW polo machine. If the belt breaks down, the engine will be seriously damaged and it will be overhauled.

If the belt is installed

Under normal operating conditions, the drive is changing in scheduled mode after 90 thousand km.

During this time, he uses its resource and becomes unfit. Special attention should be paid to new parts, since the service life of the engine depends on their quality. Polo sedan is a rather popular car, so accessories are manufactured by many manufacturers.

It is advisable to choose to do it in favor original spare parts: This is guaranteed to save funds on a possible additional repair.

The initial symptoms of the worn belt timber are:

• Slipping of the tensioner with the subsequent weakening of the belt tension;
• Overheating of the motor, which leads to the boiling of antifreeze and the frequent turning on the fan for cooling the coolant;
• Peculiar noise during the operation of the motor;
• Power loss, the engine stalls and does not start;
• The appearance of cotton in the injector receiver and silencer;
• When examining the timing belt, cracks were found, profile walkways, mechanical damage.

All such faults speak of the displacement of the phases of gas distribution and the weak drive tension. If one of the listed faults is detected, then you need to contact the maintenance station to replace this an important element Engine.

Volkswagen Polo with timing belt

How many times the timing belt on the Volkswagen Polo depends also on which manner ride, how often is used extreme driving. In such cases, changing the timing belt is needed as its wear and abrasion of profiles.

When replacing the timing of the timing, other concomitant parts of this mechanism should be changed immediately. It is recommended to use for VW polo with a CFNA engine of 105 liters with the following articles.

Attention! Spare parts for polo have a different cost, which depends on the manufacturer. In this case, it is recommended despite the overestimated price, choose a proven and well-known manufacturer so that after the replacement it was complete confidence in the reliability of the installed parts.

If the chain is installed

From 2015, the Volkswagen Polo with a drive in the form of a chain was shown from the conveyor. Determine such an engine on the VW sedan polo machines can be marked: CFNA - 105 liters. from.; CFNB - 95 liters. from.

It would seem that the decision was found on the reliable drive, because all segments in such an element are made of metal, and it is undoubtedly stronger than the belt material. But is it really? How many times during the operation of the engine you need to replace the timing chain on the Volkswagen Polo? Why some manufacturers recommend changing the chain every 60 thousand mileage or 3 years of operation, then every 30 thousand km or once every 2 years.

First, it is necessary to take into account the volume of the engine. Conditionally accepted on motors up to 1.4-1.6 liters to install belt drive GDM, and over 1.6 liters chain. The more powerful the motor, the greater the load on this element, and the more often the drive must be changed.

Secondly, on cars Volkswagen Polo, as a rule, turbine engines A chain is installed, and on simple atmospheric motors - belt. At the same time, a hydraulic tensioner is used on motor turbine. Such a device automatically stabilizes the tension of the chain, that is, when rotating this element, the piston of the stretch device is balanced.

Attention! If the polo has an engine with a chain transmission on the TRG, then the oil is subject to a mandatory replacement every 8-10 thousand km.

Always clean oil in a turbine motor, it is necessary that in the links of the chain did not get small particles of garbage, sawdust, etc. as well as the main reason is that under the piston of the tensioner did not get a garbage and he did not swap. Otherwise, if there is no balanced piston stroke, the chain drive will work incorrectly and quickly fails.

Volkswagen Polo with timing chain

Moreover, the polo engines sedan with a turbine oil burns much faster than on ordinary force aggregates. So that the question did not arise when changing the chain drive of the timing to the polo sedan, experts recommend to navigate during the diagnosis no longer on the mileage, but on the sound. Once the drive tension will weaken, the enhanced characteristic noise from the engine will appear.

Vitaly. 7. 06. 2018. Motor Volkswagen Polo Sedan 1.6. Equipped with chain timing. Metal chain should exclude a break and guarantee a longer service life. But in fact, she quickly stretched and demands replacement for 70 thousand km. You need a reverse stroke block in this drive, and it works only at the expense of oil pressure, which is created only after starting the engine.

Oleg. 8. 08. 2018. Good afternoon. I have a Motor with a vehicle with a timing of timber, and not a chain. At the same time running 80 thousand km. I recommend replacing it, for such a drive it is completely appropriate.

Vladimir. 9. 08. 2018. At Volkswagen Polo with gasoline engines 3.2 and 3.6 manufacturers write that it is possible to change the chain through 150 thousand km. But I have a replacement of the drive chain - a fairly frequent procedure, because it is single-row and stretches quickly. I recommend, if there is a choice, then buy a car with a double row chain, and then you can forget the timing of the timing.

Vadim. 4. 08. 2018. Mileage on the Volkswagen Polo was 8 thousand km. Curious observation: the tract is spent more fuel than in the city. The chain on the sedan is delivered by a double row, its resource manufacturer guarantees 120 thousand km. While everything is fine, there are no significant comments.

Anatoly. 12. 09. 2018. The right bearing of the hub was replaced. After 65 thousand km. He began to notice the chain's cloak on the cold. I went to a hundred on preventive repair - they say, you have a chain timing chain. I had to replace, although according to the regulations, it was still possible to drive the same.

Sergey. 18. 09. 2018. My polo has already departed 150 thousand km on one timing belt. And everything according to my inexperience, it turns out, according to the instructions it was necessary to change in 90 thousand km. Do not repeat my mistakes. However, I want to say thanks to manufacturers. Yes, the belt rustled, vibrated, worn out, but did not break through!
