Timing timing chain or belt? Polo A04 Trend Model BUD542656 with 1.4 L engine on mechanics. On the diagnostics of the engine in the service of LLC "German House" before its purchase during running 84 thousand km, recommendations were prescribed: 1. The timing of the timing is replaced. 2. Roller tension drive belt - replacement. 3.Realous tips and steering traction - replacement. In words, they said that you can still ride, but in the spring it is necessary to us :-) I read the forums and began to doubt: wasn't it divorced in this German house? Machine to my purchase was operated by one owner - a girl. It did not differ aggressive ride. The forums write that Polo 4 Spanish assembly is very reliable car And the replacement of the chain, and not the timing belt may be needed after 150, and even 200 thousand land.

Good day. The engine is installed on your car, which is given by the timing belt, not with a chain. With this mileage, recommending it to replace - absolutely appropriate. I would even recommend doing it at least than every 80 thousand km. Steering tips and cravings - you can only check the diagnostics of the suspension on another service if there are doubts. There are practically no external signs of the replacement of the belt. Microcracks are not visible to the eye, and the belt varies in temporary criteria or kilometers. As I wrote, adhere to the interval every 80 thousand km (with strong loads, every 60 thousand km) or every five years.
THANK YOU. I would also like to understand the character of the start and operation of the engine: what signs?
Nizhny Novgorod, Volkswagen Polo.
The timing belt is installed on your engine. With the slightest wear (loss, cracks, disintegration), it needs to be changed, as well as in running (every 90,000 km run, when operating in difficult conditions, change more often). Starting the engine will be normal, it is necessary to check in appearance. The belt rollers should also be changed, the second scheme is indicated for the replacement kit. Steering tips and thrust are checked by fact, if there is a backlash, then change. As a rule, after purchase it is necessary to change (not trust the seller) all liquids (oils) and timing belt. Also check brake pads and discs, chassis, steering.

It is necessary to replace the timing belt in a timely manner volkswagen car Polo. In the event of a cliff, the engine will be seriously damaged, it may be necessary for repair. Especially carefully close to the selection of spare parts - the durability of the motor depends on it.
This car is quite popular, because all the spare parts available on it are represented by many manufacturers. In the auto parts market there are original parts and analogues.
They differ in quality, durability. If possible, the choice should be done precisely in favor of the original parts. This will save money on additional repair, extend the service life.
Effects undime replacement timing belt, other components:
- the roller begins to slip, with the time "tensioner" ceases to cope with its task;
- the engine overheating is that it can lead to boiling coolant;
- the belt is pulled out and breaks.
Details on Volkswagen Polo differ in price primarily depending on the manufacturer. Before buying new component parts Timing, you should make sure of its availability on a particular engine.
Since 2015, it began to produce a Volkswagen polo with a drive chain instead of a belt. Accordingly, the replacement is required at an order less often. Also somewhat different components. Determine the type of motor is simple enough:
- the belt was installed on the cars released since November 2015;
- the chain is used in VW machines Polo Sedan Weed from 2010 to 2015 - with special build-screen notation (CFNA - 105 hp, CFNB - 95 hp).
Replacement should be carried out at once all parts of the belt mechanism. The list includes the following:
- tensioner roller;
- drive belt itself;
- roller roller.
Article numbers of original parts:
- tension Roller - VW Polo with engine CFNA. 105 hp - 03C145299C;
- roller Obvironment - VW Polo with air conditioning with CFNA engine 105 hp - 1J0145276B;
- original belt - on the VW Polo sedan with air conditioning - 6Q0260849e.
The cost of the details:
The best solution is to replace exactly on the original details. But the cost of this sometimes 2-3 times more than analogues. The repair process with your own hands is possible, but difficult. In addition, the assistant will be required.
Read how much the repair is, you can on the Internet. The cost is varied again in official dealer centers and private service companies. Actual price for spare parts depending on the manufacturer:
| the name of detail | If without air conditioning, article | Cost, rubles | If with air conditioning, article | Cost, rubles |
|---|---|---|---|---|

Description Replacing the timing belt on Volkswagen Polo
The process of replacing the parts of the gas distribution mechanism is complicated, requires skills and tools. Special difficulties cause the need to replace the tags. The process involves the use of observation pit, overpass, or lift. The belt tension is carried out by a special device. Appearance Mechanism:
The replacement algorithm is almost no different on the volume motors 1.4 and 1.6. Includes the following main steps:
- it is necessary to dismantle the liner front wheel by car;
- next, with the help of the head with 12 edges, 22 will need to be checked crankshaft per pulley mount bolt - clockwise;
- next, the belt itself is carried out - if there are even small cracks, breaks, or detachment must be replaced;
- to loosen the timing belt tension, it is required to use the key "on 16" - then the tension roller fastening bolt is unscrewed;
- the roller bracket will need to be checked counterclockwise - it is required to make some effort, overcome the resistance of the spring of the tensioner;
- next, you will need to turn the roller against the clockwise arrow - for this you will need to overcome the resistance of the device responsible for the belt tension;
- the remant of the belt itself is performed;
- the tensioning device should be fixed in a pressed position - with the help of submitted means or assistant;
- using the key to 16 - you need to check the roller bracket counterclockwise - prior to the coincidence of the holes;
- next, you need to wear the belt on the rollers and the assembly is performed in the reverse order.
Performing such work alone is difficult. The price in a private car service starts from 5-6 thousand rubles, in an authorized center the amount on such work will be required by 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 installed original detail, and analog.
If a special fixing tool for some reason is absent - then you can use the usual nail or other long metallic, quite a solid rod. It will be enough to insert into a special hole on the pulley as in the figure below.
Before removing the belt itself, you need to mark with a chalk or a place marker, make tags - to avoid the wrong arrangement of it. In the event that the mechanism is not tames, it is possible that the engine is simply not started. If necessary, you can try to replace and on the usual jack. But this procedure often implies complexity.
Replacing the timing belt and all other parts of the mechanism should be carried out taking into account all the features of the execution of this operation. First of all, it is important to prepare the necessary tools in advance. This will significantly speed up the work process itself.
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 You need to pay for new parts, since the engine life 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 precisely in favor of 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 S. timing belt
How many times to change the timing belt on the Volkswagen Polo depends on what kind of driving manner, how often the extreme driving is used. 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 the Volkswagen Polo cars, as a rule, a chain is installed on turbine engines, 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 is the engine with chain transmission On timing, 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 have a sedan with a turbine, the oil is much faster than on ordinary power units. 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 more long term Services. 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!
On VW Polo cars, it is necessary to change the belt of the gas distribution mechanism every 75-80 thousand km. It is recommended to check the belt every inspection for bending, scuffing and stretching, in order to avoid the random belt break in the middle of the road.
The first symptoms of the worn belt is a characteristic knock when operating the engine. It also affects his unstable work (little power, stalls, poor response to the accelerator pedal). If the engine is stamped and no longer starts - most likely, this is a strap of the gas distribution mechanism.

The importance of the belt of the gas distribution mechanism on modern cars
The timing plays an integral role in stable work Engine of any car. A malfunction or critical wear affects the entire car. He simply won't go. In the case of small engine (up to 1.4), the torn belt of the gas distribution mechanism eats and the flap of the valve.
