First-class timing replacement for VW Polo (Volkswagen Polo sedan) and its belt. Removing, replacing, installing the Volkswagen Polo timing chain when changing the timing belt

A drive belt is an element of a belt drive that serves to transmit torque. The transmission of torque occurs due to friction forces or engagement forces (timing belts).

in VW vehicles Polo sedan a belt drive is used that transmits torque from the crankshaft pulley of the CFNA (CFNB) engine to the pump (coolant pump), bypass roller, tensioner pulley, alternator pulley and air conditioning compressor pulley.

If you do not change the belt on the polo in time, what will happen?

During its operation, the Volkswagen Polo Sedan drive belt is pulled out. This is provided by the manufacturer, in connection with which the mechanism drive belt tensioner pulley installed.

However, the tensioner roller's stroke is also limited, when it reaches the limiter, the belt begins to slip in the Volkswagen Polo drive mechanism, as a result of which it heats up. Overheating leads to a broken belt.

If in time (according to the prescribed regulations) the drive belt is not replaced on the car Volkswagen Polo With CFNA engine(CFNB) 105 hp (85 hp) equipped with an air conditioning system, this will break the drive belt, resulting in the following consequences:

In the absence of a drive belt, torque is not transmitted to the pump, respectively, the pump does not work (coolant supply pump). The lack of forced circulation of the coolant leads to overheating of the Polo sedan engine.
- in the absence of a drive belt, torque is not transmitted to the polo sedan generator. Accordingly, the electrical part of the car will work for some time from the car battery, until it is completely discharged.
- in the absence of a drive belt, torque is not transmitted to the air conditioning compressor, but this is not the most critical in this situation.

Thus, the most dangerous thing when the drive belt of the polo sedan breaks is the absence of forced circulation of the coolant, which quickly leads to overheating of the VW Polo sedan engine.

Replacing the timing belt polo sedan

Attention! On VW Polo sedan cars from 2010 to November 2015, engines with the letter designation CFNA (105 hp) and CFNB (95 hp) were installed. In these cars, the engines use a chain in the timing mechanism. Replacing the timing chain in the VW Polo sedan is not regulated by mileage and service life.

Replacing the timing belt is only possible in polo sedan engines installed from November 2015. More about CWVA engines read here.

To begin with, perhaps, it is worth mentioning the investments invested in the project - 250,000,000 euros, which is half as much as GM spent on business restructuring before leaving Russia. And now buyers of "Volkswagen" products, in theory, can count on cheaper prices (although in practice, of course, this is far from a fact - remember the "Kaliningrad" BMW, which in some cases is more expensive than imported from abroad). And, finally, the launch of the plant means the appearance of additional jobs (there are no more than four hundred, so you are already late). As for the new modern engine, which will be produced here, then, according to the assurances of the representatives of the plant, it will no longer tap the valves and cause problems in the cold. It will go to models of mass segments, in particular, Volkswagen Polo, Jetta, as well as related Skoda Rapid, Octavia and Yeti. This is good, especially since, compared to the previous series of EA111 engines, the fresh unit with the EA211 index received a modified cylinder head, valve springs, oil and water pumps, crankshaft, connecting rods and pistons. True, consumers should not expect gifts of fate from VW. And that's why.

The technical director of the enterprise, Vitaly Nakhtigel, in an interview with reporters, said that, speaking of the upgraded 1.6-liter four-cylinder MPI engine, whose return has increased to 110 hp. and 155 Nm of thrust, owners no longer have to change the timing belt. How is this possible if the same VAG is in a row power units has long been using a much more durable alternative in the form of chains instead of belts, which often go longer than the engines themselves. To this question, Mr. Nachtigel replied, they say, resource tests, initiated by the manufacturer, proved that the belt remains operational throughout the entire life of the motor. And, alas, he refused to explain what period of operation or, more simply, the number of kilometers driven, he refused to explain, referring only to the fact that the suitability of this unit will be in without fail check as part of scheduled maintenance. He also added that it is not superfluous to drive the car to official dealer for separate engine diagnostics every 40,000 km. In general, pay money regularly and, if necessary, the timing will still be replaced for you. By the way, if you want to check its condition somewhere in the service of a friend, forget about the subsequent manufacturer's warranty once and for all.

Here is such a bike about an innovative engine, which is also worth adding that it supposedly does not need to be warmed up at low temperatures at all. Even the figure "minus 38" was announced. Great news, unless, of course, over-gasping or a peppy start on a cold start does not lead to scuffing in the cylinders, as is observed in the whimsical engines of the Porsche Cayenne, the whole Audi family and the same VW Touareg. And how are things in the summer - will the cooling system cope so that it does not boil? Volkswagen representatives answer all questions not exhaustively in the same way - "these are new technologies and the consumer does not need to open the hood more than once a week to fill in the washer fluid on their own, and we will do the rest ourselves." However, here they, of course, do not deceive. In the same Audi engines, which have become, in fact, consumables, are changed under warranty with enviable regularity. Yes, and they will look at MOT for your hard-earned money and replace it. Among the obvious advantages of EA211 are reduced weight, reduced noise level, as well as the possibility of feeding with 92nd gasoline. Still, however, the Germans mentioned a 10% reduction in fuel consumption, and, accordingly, the minimum amount of emissions of toxic substances into the environment. But the buyer will have to check this, as well as the resource capabilities of the motor as a whole, on his own - during the operation of the machine after its purchase.

It is necessary to timely replace the timing belt on a Volkswagen Polo car. In the event of a break, the engine will be seriously damaged and may need to be repaired. Particular attention should be paid to the choice of spare parts - the durability of the motor depends on this.

This car is quite popular, because all the spare parts available for it are represented by many manufacturers. The auto parts market has original parts and analogues.

They differ in quality and durability. If possible, the choice should be made in favor of original parts. This will save money on additional repairs, extend the service life.

The consequences of untimely replacement of the timing belt, other components:

• the roller begins to slip, over time, the "tensioner" ceases to cope with its task;
• the engine overheats - which can lead to boiling of the coolant;
• belt stretches and breaks.

Parts on the Volkswagen Polo differ in price primarily depending on the manufacturer. Before buying new constituent parts Timing belt, you should make sure that it is available on a particular engine.

Since 2015, they began to produce Volkswagen Polo with a drive chain instead of a belt. Accordingly, replacement is required much less often. The components are also slightly different. Determining the type of motor is quite simple:

• the belt was installed on cars manufactured from November 2015;
• the chain is used in VW Polo sedan cars produced from 2010 to 2015 - with special letters(CFNA - 105 hp, CFNB - 95 hp).

Replacement must be carried out immediately of all parts of the belt mechanism. The list includes the following:

• tensioner roller;
• the drive belt itself;
• bypass roller.

Article numbers of original parts:

• tensioner pulley - VW Polo with CFNA 105 hp engine. — 03C145299C;
• bypass roller - VW Polo with air conditioning with CFNA 105 hp engine. — 1J0145276B;
• original belt - for VW Polo sedan with air conditioning - 6Q0260849E.

Parts cost:

The best solution is to replace with original parts. But the cost of those is sometimes 2-3 times more than analogues. Do-it-yourself repair is possible, but difficult. In addition, you will need an assistant.

You can find out how much repairs cost on the Internet. The cost again varies dramatically in official dealer centers and private service companies. The current price of spare parts depending on the manufacturer:

Description of replacing the timing belt on a Volkswagen Polo

The process of replacing parts of the gas distribution mechanism is complex, requires skills and tools. Of particular difficulty is the need to replace the labels. The process involves the use viewing hole, overpass or lift. Belt tension is carried out by a special device. Appearance mechanism:

The replacement algorithm is almost the same on engines of volumes 1.4 and 1.6. Includes the following main steps:

• it is necessary to dismantle the right fender liner front wheel by car;
• then, using a head with 12 faces, it will be necessary to turn 22 crankshaft for the pulley mounting bolt - clockwise;

• then the belt itself is inspected - if there are even small cracks, tears or delamination, it is necessary to replace it;
• to loosen the timing belt tension, you need to use the “16” key - then the tension roller fastening bolt is unscrewed;

• the roller bracket will need to be turned counterclockwise - some effort is required to overcome the resistance of the tensioner spring;

• then you will need to turn the roller already counterclockwise - for this you will need to overcome the resistance of the device responsible for the belt tension;
• the belt itself is dismantled;

• the tensioner should be fixed in the pressed position - with the help of improvised means or an assistant;

• using a key of 16 - you need to turn the roller bracket counterclockwise - until the holes match;
• then you need to put the belt on the rollers and the assembly is carried out in the reverse order.

Doing this kind of work alone is difficult. The price in a private car service starts from 5-6 thousand rubles, in an authorized center the amount for such work will be required an order of magnitude more. It is worth noting that the belt resource is approximately 40-50 thousand km. But it is recommended to replace a little earlier. Especially if not an original part is installed, but an analogue.

If for some reason there is no special fixing tool, then you can use an ordinary nail or other long metal, strong enough rod. It will be enough to insert into a special hole on the pulley as in the figure below.

Before removing the belt itself, it is necessary to mark the place with chalk or a marker, make marks - to avoid its incorrect location. If the mechanism is not installed according to the marks, the engine may simply not start. If necessary, you can try to replace it on a conventional jack. But such a procedure often involves difficulties.

Replacing the timing belt and all other parts of the mechanism must be carried out taking into account all the features of this operation. First of all, it is important to prepare in advance necessary tools. This will significantly speed up the process itself.

Volkswagen cars are distinguished by their reliability, durability and high accuracy of all systems. This is also true for the Polo, one of the most popular models in Russia. German manufacturer. Many cars of this version use a gear drive mechanism. It is recognized as the most durable and resistant to mechanical wear.

Most car owners, referring to the factory reliability of the transmission mechanism, rarely turn to a car service for its scheduled maintenance. This, in turn, can lead to much more serious problems with the internal combustion engine itself.

Replacing the timing chain on the Polo Sedan according to the regulations in our car services

The timing chain requires periodic inspection and maintenance. According to the factory specifications, this mechanism for the Volkswagen Polo does not need to be changed throughout the entire period of operation of the car, if it is in good condition. Maintenance of Volkswagen cars and Polo Sedan replacement of the chain, the regulations of which are established by the manufacturer, are carried out only if a clear breakdown of the mechanism is suspected.

What do we offer when you need a chain replacement on a Polo

However, the quality of the road surface becomes a real test even for the most reliable car brands. High loads, aggressive driving lead to the fact that the tension between the links decreases, the distance between the teeth grows. The chain slips, all the work of the timing is disrupted, which threatens trouble with the car engine.

On a Volkswagen Polo Sedan, a chain replacement may be necessary in two situations:

1. When worn out.
2. When it is mechanically damaged.

Attention! If this transmission mechanism is not replaced in time, the engine can get a serious malfunction (defects in pistons, valves, etc.)

In our car service we offer:

1. Implementation scheduled maintenance Timing.
2. Diagnosis of the chain transmission mechanism.
3. Direct replacement of the timing chain.

In the last procedure, it is important to sort out and change all the components. Sprockets and pumps, camshaft and crankshaft oil seals should also be checked.

Otherwise, the likelihood of re-assembly of the assembly and costly repairs increases.

How to determine what is needed on a Volkswagen Polo Sedan chain replacement

The timing chain cannot break, but it is subject to significant stretching. Its total length grows, as the gap between the links increases, and backlash occurs.

The transmission tension becomes weaker, which threatens with problems with the engine. If not promptly repaired, a stretched chain can jump a few teeth. As a result, the operation of the entire gas distribution mechanism is disrupted. Damaged valves, pistons, crankshaft.

To prevent such troubles, it is necessary to check the chain transmission mechanism at each scheduled technical inspection.

The fact that a chain is close to wear can be determined by careful electronic diagnostics engine. But car owners rarely spend it. A common misconception is that this item"eternal", and its replacement is postponed until the last moment.

But you should contact a car service immediately if the following signs of a malfunction appear:

1. Unreasonably increased fuel consumption.
2. The noise increases when starting the engine.
3. Misfires occur.
4. The dynamics during acceleration of the car deteriorates noticeably.
5. The check engine light came on.

The presence of these symptoms indicates the need to visit a car service, where professional craftsmen will diagnose the transmission mechanism and replace the Volkswagen Polo timing chain.

FUNCTIONAL PURPOSE OF THE TIMING BELT

Replacing the timing belt is part of the scheduled Maintenance Volkswagen car Polo and plays an important role in engine performance vehicle. Untimely replacement belt can lead to a malfunction of the motor, and a break to deformation of the valve timing mechanism and the need for overhaul engine.

All parts of the gas distribution mechanism are closely related to each other, air injection fuel mixture drives the piston of the engine cylinder, which in turn pushes the crankshaft connected by a drive belt with camshaft. Thus, there is a movement of the camshaft, which regulates the frequency of movement of the valves. The Volkswagen Polo timing belt connects gears and transmits torque from the crankshaft to the camshaft, affecting its speed of rotation. If the system is working, the frequency of their revolutions should be equal.

TYPES OF FAULTS OF THE TIMING BELT

1. Timing belt wear leads to a change in the torque transmission force from the crankshaft to the camshaft, resulting in a change in the frequency of movement of the pistons and engine valves. This, in turn, leads to a malfunction of the gas distribution system, rapid heating of the engine and, as a result, a decrease in engine power and an increase in the consumption of the fuel mixture. For reliable and trouble-free operation of the motor, it is necessary that the valves close and open at the same frequency as the engine pistons. If, due to wear, the timing belt slips, this can cause a break.
2. A broken timing belt for a Volkswagen Polo is the most dangerous engine damage. In the event of such a malfunction, the camshaft ceases to be associated with crankshaft and can stop completely arbitrarily in a position in which any of the valves of the gas distribution mechanism is open. In this case, the piston, moving up, may collide with the valve, which will lead to its deformation. In this case, the car's engine is in danger of serious repairs. It should be noted that a timing belt break does not occur unexpectedly, it is almost always accompanied by changes in the operation of the car engine, a decrease in its power, a change in gasoline consumption, the appearance of extraneous squeaks, squeaks, etc.

To prevent and prevent the operation of the gas distribution mechanism, it is necessary to periodically replace the timing belt, this will save the engine of the Volkswagen Polo car from breakdown, warn premature wear engine and increase its lifespan.

CAUSES AND ASSESSMENT OF WEAR OF THE TIMING BELT

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

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

• the appearance of oil and antifreeze smudges that can chemically destroy the timing belt, with prolonged exposure;
• the occurrence of longitudinal cracks on the back surface of the belt;
• the formation of transverse cracks on the inner surface of the drive belt;
• a ragged surface and a violation of the integrity of the edge are also a sign of wear;
• belt wear is also indicated by rubber dust on the surface of the part;
• if the timing belt teeth begin to peel off or wear out, the part must be replaced immediately with a new one.

SYMPTOMS OF A FAULTY TIMING BELT

1. Increased consumption of gasoline by car
2. Decreased engine power
3. Full stop of the car on the go, when you try to start the engine does not start, and the starter rotates easier than usual
4. Unstable operation of the engine Idling and in motion;
5. The occurrence of shots in the injector receiver and exhaust pipe

All these problems may indicate a shift in the valve timing and loosening of the belt tension. If you notice one or more signs of this list on your Volkswagen Polo, immediately contact the service station for an inspection.

HOW OFTEN SHOULD YOU REPLACE A Volkswagen Polo Timing Belt?

The frequency of replacement of any Supplies for cars depends on driving style and mode of operation of the car. With extreme driving style and aggressive use of the vehicle, it is necessary to replace the timing belt as it wears out and the teeth wear out.

Under normal operating conditions, it is necessary to replace the original timing belt as scheduled, every 60 - 70,000 km. run. During this period, it develops its resource and becomes unusable. If an analog belt is installed on your Volkswagen Polo, the replacement must be done a little earlier than the period recommended by the vehicle manufacturer.

WHICH TIMING BELT IS BETTER TO CHOOSE

Modern belts for the gas distribution system are a high-tech product, characterized by increased strength and wear resistance, capable of withstanding high dynamic loads. Timing belts are produced from neoprene or polychloroprene reinforced with strong fiberglass, nylon and cotton cords.

1. To avoid the mistake associated with buying a timing belt, contact the specialists who will help you order a timing belt suitable for your car engine using the WIN code of your car. This part is one of the most important in the design of the motor, the slightest deviation in the length, width, shape and size of the teeth can lead to malfunctions in the Volkswagen Polo engine.
2. Do not try to save money when buying a timing belt, a cheap product can be a low-quality fake that will quickly become unusable and can cause serious engine damage in the future. The best option for any car, there are original parts, their cost is higher than analog ones, but during the operation of the car they quickly pay for themselves.
3. When buying a timing belt, check it for stiffness, good belt should be elastic and easy to bend. The worse the belt, the more rigid it will be.
4. The presence of teeth, sagging, pores on the belt is not allowed - these are signs of a poor-quality belt that will quickly become unusable. The surface of the product must be smooth, small burrs are allowed.
5. At self-purchase check the timing belt part number printed on the back side, it must match the WIN code of the car. If it is not possible to compare the code of the belt and the car, then it is necessary to make a visual comparison of the old and new belts, they must be completely identical.
6. To avoid buying a fake, try to purchase spare parts only from authorized, trusted dealers.
7. Don't save on qualified replacement timing belt, contact our certified car service, where competent mechanics will help with the repair of your Volkswagen Polo. And in the spare parts store you can buy original spare parts for your car.
