A broken timing belt on a Lada Largus can cause costly engine repairs due to bending of the valves, which rest against the pistons. Of course, it is under no circumstances worth bringing the equipment to such a state; to do this, you need to regularly service the engine and replace components that have exhausted their service life. The manufacturer usually sets a service life of at least 120,000 km, but this does not mean that all this time you can not look under the hood of your car.
How to check the condition of the belt on Largus
A broken timing belt on Largus leads to the fact that the valves remain open, and the pistons hit the “plates”, bending them. Such a breakdown leads to a major overhaul of the cylinder head and replacement of the pistons.
To prevent this from happening, you need to be able to recognize increased wear on the timing belt. Currently there are two ways to assess its serviceability:
- visual inspection;
- extraneous sounds.
An external inspection helps assess the visual condition of the belt. There should be no cracks or protruding burrs on it. It should be smooth and neat. An external assessment of the product can only be carried out with the protective screens removed.
Extraneous sounds can only be discerned by an experienced driver. If there are burrs on the old belt, they will hit the gears and other mechanisms with a characteristic soft sound. This may be a reason to inspect the timing belt.
Diagnostics
In the case of scheduled maintenance according to the regulations established by the Togliatti automaker, as well as upon contact when signs of a malfunction of the generator drive and/or timing belt appear, first of all, diagnostics are carried out by the technicians.
The conversation is primarily about visual inspection. The engine is checked for traces of leakage of certain fluids, especially engine oil, and the condition of the generator drive is assessed (in some cases, additionally the drives of the power steering pump and air conditioning compressor). To check the condition of the timing belt, it is necessary to partially disassemble the engine
Attention is drawn to the presence of traces of deformation, various liquids, damage
The regulations indicate that it is necessary to check not only the condition of the belts, but also the degree of their tension. For this purpose, our specialists use instrumental diagnostics. Depending on the situation and type of belt, mechanical devices are used (their operation is based on the principle of a dynamometer; the force applied to bend and retract the belt is measured and compared with factory parameters) and electronic (high-frequency sounds are measured). The experience and skills of the craftsmen make it possible, if necessary, to use traditional methods of visual assessment of the degree of belt tension.

How to select components for replacing the timing belt on a Lada Largus
The most important thing when selecting this product is the manufacturer. The car owner must be able to distinguish between manufacturers from whom timing belts can be purchased. Below is a list of trusted manufacturers you can trust:
- Renault;
- Lada;
- Gates;
- Contitech;
- Bosch;
- Dayco;
- Lemforder.
Often, original kits may contain belts from manufacturers such as Gates or Contitech. Therefore, there is no point in overpaying. It's better to get a cheaper set.
Another important point when choosing a timing belt is its shelf life. Since this is a rubber product, it has a limited time during which it can be stored.
Special numbers on the belt itself, for example, “5-30”. The number 5 means the year - in this case 2015, and 30 is the number of the week in which the product was manufactured. The permissible storage period of the belt is 5 years. If its age is higher, it is clearly not worth installing such a spare part.
If you install a timing belt on a Lada Largus with an expired expiration date, its breakage may occur even earlier than the required replacement according to the regulations - after 10 or 20 thousand kilometers. By the way, it is after this that bad reviews about the best manufacturers may appear.
To find out the expiration date, just pay attention to the special inscriptions placed on the packaging. For example, “Install < 08.2021”, as in the photo above. This means that this belt can be installed no later than August 2022.
Other disadvantages of the model
The gasoline consumption of the Lada Largus is higher than that of the Kalina station wagon by 1.5 liters, with a weight difference of only 80 kg. Engine vibration occurs as soon as the tachometer needle reaches 1500 rpm. The rpm often jumps or drops to 500. When driving at a speed of more than 90 km/h, the ears begin to pop, like in an airplane during takeoff. This upsets many car enthusiasts, because at these moments they want to stop the trip and get out of the car.
The lack of rear mudguards is a big drawback of the presented model. Ball joints pressed into the arms will make it difficult to repair the suspension in the future. The gap between the fender and the front bumper must be covered with some kind of gasket to maintain cleanliness. Dirt constantly accumulates in this area.
Limited functionality as standard - no ABC or front windows. During rainy weather, the windows constantly fog up; in this case, they need special treatment. In winter, the accelerator pedal freezes, the interior warms up very slowly, and the engine cools down quickly. Pump malfunctions occur when the car's mileage is more than 30,000 km; there are no floor mats in the cabin.

Everything is much more complicated here. To replace the timing belt on K4M engines, special shaft clamps are required, as well as camshaft plugs, since they are disposable. To access the plugs, you will need to remove the intake muffler housing.
Removing the old belt
To do this, follow these steps:
- Lift the right side of the Lada Largus and remove the front wheel.
- Unscrew the fender liner to expose the crankshaft pulley.
- Loosen the accessory belt and remove it.
- Remove the crankshaft pulley.
- Remove the right engine mount by lifting it up.
- Unscrew the timing belt protective covers.
- We fix the crankshaft using a special device. Pre-set the timing marks. To do this, you need to remove the rear camshaft plugs and turn the CV so that the marks on them are horizontal. We fix it.
- Loosen the tension roller and remove the old rubber product.
Installing a new product
Before installing a new belt, it is recommended to check the condition of the crankshaft oil seal. If necessary, it is recommended to replace it. Next, the following list of actions is performed:
- Replace the tension and guide roller. The tension roller bolt must be tightened by hand.
- We put the timing belt on from top to bottom.
- To tension the belt, you need to insert the hexagon into a special hole and turn the eccentric until the flag is aligned with the slot.
- After tensioning the belt, tighten the pulley bolt.
- Pull out the clips and turn the crankshaft two turns.
- Check that the marks match. If everything is in order, reassemble in reverse order.
Attention! Do not reinstall the old camshaft plugs. Be sure to replace them with new ones to avoid oil leakage!
Tool
To carry out work on a 16-valve engine you will need:
- A set of wrenches (open-end and ring spanners of the most common sizes - 10, 13, 14, 16, 18);
- A set of heads with rods and a knob (same sizes);
- Torx type bits;
- Set of hexagons;
- Screwdrivers (flat, Phillips);
- Long power flathead screwdriver or pry bar;
- Wooden beam;
- Rags.
To perform the operation, you should stock up on a new belt, as well as tension and support (parasitic) rollers assemblies, since these elements also need to be replaced.
How to change the timing belt on an 8 valve Largus - K7M
The engine is similar to the 8-valve VAZ engine. Replacing rubber products is also easy, but with the use of special tools.
Removing a worn timing belt
By analogy with K4M, we perform the following actions:
- Lift up the right wheel and remove it.
- Remove the belt and fender liner protection.
- We loosen and dismantle the belt of auxiliary units.
- Raise the engine and remove the right engine mount.
- Remove the timing belt protective cover.
- Break off the crankshaft pulley bolt and remove the last one.
- Remove the lower timing cover.
- Turn the crankshaft until the mark in the photo matches.
- Make a chalk mark on the crankshaft sprocket and cylinder block.
- Unscrew the nut securing the tension roller and remove it by removing the old belt.
Installation of a new rubber product
If the pump is replaced along with the replacement of this part, then first you need to remove the old sealant and thoroughly clean the mating surface of the cylinder block. Install the new pump using sealant. Don't forget to install the gasket. Then follow these steps:
- Install the new tension pulley onto the stud and tighten the nut by hand. The roller should stand in such a way that the direction of rotation coincides with the direction of the arrow on the roller body.
- Install the new rubber product so that its bottom mark coincides with the mark on the KV sprocket.
- We put the belt on the RV so that its mark coincides with the mark on the gear.
- Using a wrench, tighten the tensioner nut until the mark matches. The same as on the VAZ engine. Fully tighten the nut to 30-40 Nm.
- Check the alignment of the marks by turning the crankshaft clockwise several times.
Attention! Weak belt tension will cause the teeth to jump and shift the valve timing. This is fraught with problems with valves and pistons! Be careful!
