Today I came to visit my old friend, barbecue and all that, and in between, a small maintenance on his freshly painted VAZ 2114, replacement of the timing belt, rollers and pump. This car has a standard eight-valve engine and this greatly simplifies the matter, since on this engine the procedure for replacing the timing belt takes 30 minutes. In our case, the timing belt was eating up a little on the inside and one of the oil pump bolts was to blame for this, we’ll talk about this at the end of the article.
On the VAZ 2114 engine there are 8 valves, if the timing belt breaks, the valve does not bend.
Under standard conditions, the timing belt replacement interval is 60 thousand kilometers or four years of operation, whichever comes first. The replacement interval can be increased to 80 thousand with periodic monitoring of the condition of the belt, roller and pump.
Preparatory operations
Open the hood.))
It's immediately obvious that the owner loves his car.
VAZ engine 8 valves.
If you plan to replace the pump, then let the engine cool, remove the protection and then drain the antifreeze. It is enough to drain only from the cylinder block.
Plug on the cylinder block.
Jack up the car and remove the front right wheel and plastic mudguard.
Common mistakes
- Malfunction: the belt began to whistle after replacement. In reality, it is not the belt itself that whistles, but only the roller. It had to be replaced.
- If several teeth on the old belt were torn off, the cause could be a jammed pump. Check if this is the case and replace it (drain the coolant).

- Do not install automatic roller 21116-1006238 instead of the standard tension roller.
Step-by-step instructions for replacing the timing belt
- Unscrew the two bolts from the side of the timing belt protective cover. Key for 10.
- And one in front, remove the cover. Key for 10.
- Remove the generator drive belt. Loosen the locking nut, set the wrench to 13 and unscrew the tension bolt, set the wrench to 10. Move the generator towards the cylinder block.

conclusions
Incorrect timing belt tension will lead to accelerated wear.
Accelerated wear of the timing belt due to incorrect tightening.
The engine on a VAZ-2114 does not bend the valve when the timing belt breaks, but still, there is a risk of getting up at night in a dark field in our big country. You will be lucky if the belt breaks at home or at work, and not on a long trip. To prevent this from happening, you need to set the timing belt correctly, as we wrote above!
A specialist at a service station or an experienced car enthusiast who has already performed this procedure several times will be able to replace the timing belt in a few minutes. Another thing is for a car owner who has encountered this for the first time and does not know how to set timing marks on a VAZ 2114. In this case, the process will take much longer.
At the same time, the better a person knows the very operating diagram of the engine and the functions performed by the part being replaced, the easier it will be for him to understand the features and subtleties of the replacement. So let's understand the theory.
Installing a new timing belt
- We get a new timing kit, in our case from Gates.
Gates timing kit.
- For a VAZ 2114 engine with 8 valves, it contains a toothed belt and a tension roller.
- If anyone needs it, the article number on the box is as follows.
- We check that all marks match. We install the tension roller in place, but do not tighten the nut. Next, install a new timing belt, put it first on the crankshaft sprocket, then on the camshaft sprocket, tension roller and pump. We make sure that the descending branch of the belt is tensioned.
- Using a special wrench, turn the tension roller and tighten the timing belt. Tighten the nut.
- The correct tension is considered to be one in which, with two fingers, we can turn the timing belt in the longest section by a maximum of 90 degrees.
A new timing belt has been installed.
- We install all parts in the reverse order of removal. Fill with antifreeze.
This procedure is so simple that you can do it yourself even without a garage, just in the courtyard of your house.
Why change the belt?
In the list of routine maintenance for the VAZ 2114, the manufacturer provides for replacing the timing belt every 60-75 thousand kilometers. However, given the quality of our spare parts, experienced car enthusiasts recommend replacing it after no more than 30-40 thousand km.
The belt should be visually inspected for visible mechanical damage at least once a month. If the slightest problem is detected, it must be replaced immediately.
If this is not done, the tension pulley may fail, as well as the water pump. In addition, there are cases when parts of the belt wrap around the generator pulley, which leads to blocking of its shaft.
But there is also good news. In VAZ 2114 cars with 8-valve engines of 1.5 and 1.6 liters, a broken belt does not threaten bending of the valves and damage to the cylinder head, which cannot be said about sixteen-valve engines, where a similar problem occurs in 90% of cases.
Causes of toothed belt wear on VAZ 8 valve engines
- Wear of the timing belt on the front side is the main cause of a worn pump, but sometimes it can also be the tension roller stud and, in very rare cases, the camshaft sprocket. To eliminate this problem, replace the worn part.
- Wear on the rear side is much less common. The main reason is the bolt on the oil pump. Over time, the belt tension weakens a little and, vibrating, it begins to reach this bolt. It’s very easy to fix this problem; we replace the Torx sprocket bolt with a regular 10mm socket, its head is smaller and the timing belt is no longer missing. The photo shows wear from the belt.

Stories from our readers
“Fucking basin. "
Hi all! My name is Mikhail, now I’ll tell you a story about how I managed to exchange my two-wheeler for a 2010 Camry. It all started with the fact that I began to be wildly irritated by the breakdowns of the two-wheeler, it seemed like nothing serious was broken, but damn it, there were so many little things that really started to irritate me. This is where the idea arose that it was time to change the car to a foreign car. The choice fell on the melting Camry of the tenth years.
Yes, I had matured morally, but financially I just couldn’t handle it. I’ll say right away that I am against loans and taking a car, especially not a new one, on credit is unreasonable. My salary is 24k a month, so collecting 600-700 thousand is almost impossible for me. I started looking for different ways to make money on the Internet. You can’t imagine how many scams there are, what I haven’t tried: sports betting, network marketing, and even the volcano casino, where I successfully lost about 10 thousand ((The only direction in which it seemed to me that I could make money was currency trading on the stock exchange, they call it Forex. But when I started delving into it, I realized that it was very difficult for me. I continued to dig further and came across binary options. The essence is the same as in Forex, but it’s much easier to understand. I started reading forums, studying trading strategies. I tried it on a demo account, then opened a real account. To be honest, I didn’t manage to start earning money right away, until I understood all the mechanics of options, I lost about 3,000 rubles, but as it turned out, it was a precious experience. Now I earn 5-7 thousand rubles a day. I managed to get the car buy after half a year, but in my opinion this is a good result, and it’s not about the car, my life has changed, I naturally quit my job, I have more free time for myself and my family. You’ll laugh, but I work directly on the phone)) If If you want to change your life like me, then here’s what I advise you to do right now: 1. Register on the site 2. Practice on a Demo account (it’s free). 3. As soon as you get something on the Demo account, top up your REAL ACCOUNT and go to REAL MONEY! I also advise you to download the application to your phone, it’s much more convenient to work from your phone. Download here.
As a result, if the timing belt tension is correct, then when the casing is removed, its long part will fluctuate within 1 cm. from the axis.
Installation process
The timing belt itself is a rubber product closed with teeth inward, which synchronizes the torque between the camshaft and crankshaft. Ignoring its wear will not lead to anything good, because in the best case, your engine will stall while driving, and in the worst case, the entire wheelbase will jam, which can lead to the most unpredictable incidents on the road.
The replacement and debugging itself is carried out in two stages, in the first stage the main repair and debugging work is carried out, and the second stage carries the function of monitoring the work done.
First stage
- The assistant gets into the car and puts 5th gear in the gearbox, and at this time you remove the front belt protection.
- Insert the ratchet into the place allocated for it and begin to turn the crankshaft, you need to do this until you see that the mark located on the camshaft has not moved to remove several teeth from the control antenna of the rear cover. (this action is necessary to reduce the degree of belt tension).
- We dismantle the drive pulley on the crankshaft and return the mounting bolt to its place.
- The assistant switches the gearbox to “neutral”.
- Again, we begin to carefully turn the crankshaft until the mark on the VAZ 2114 flywheel is in the central position.
Second stage (control-final)
- Before checking the timing marks on the VAZ 2114, you need to fix the pulley on the generator and tension the belt with a roller to the maximum.
- Now we check all the matches, if nothing is wrong anywhere, then we install the protection back and clean the workplace.
Looking under the hood of your car, with knowledge of this information, you will understand that there is nothing difficult in this procedure, but its success is quite dependent on the skill of the performer. Therefore, if something doesn’t work out the first time, just repeat the operation, you may even need to do it twice. Don’t be discouraged, because after the difficult first time it will only take you a few minutes, like a seasoned professional.
