How to remove and install a VAZ-2109 engine: with or without a box

Correct removal of the VAZ 2109 engine is necessary for scheduled and routine repairs. In most cases, temporary dismantling occurs along with the gearbox. The procedure is carried out in a specialized garage with a lift. Moreover, if a person knows how to remove a VAZ engine, everything can be done with his own hands in a few hours.

It is advisable that this procedure be carried out by a car owner with some experience. Even minor errors will lead to possible damage to individual elements of the VAZ 2109 vehicle system.

Preparatory stage

Before starting work, it is strongly recommended that you familiarize yourself with the structure of the “heart” of the iron horse. This will help avoid many problems associated with incorrect connection of individual system elements, such as:

right front support;
generator;
engine;
gearbox - it is necessary to remove the gearbox only if the engine is overhauled or replaced;
starter;
system for turning on the lights for reversing marks VAZ 2109;
stretching;
left front support;
a plug that secures the hole for draining oil from the engine;
front wheel drives on the right side;
rear support-fix;
hole for draining oil from the gearbox;
left-hand front wheel drive;
gearbox shift drive rod.

Beginners are advised to take photographs of the listed parts in assembled form. In order to successfully dismantle the VAZ engine, it is necessary to use the tools recommended by the manufacturer. A list of these can be found in the vehicle operating instructions. Regardless of the reason that prompted the need to carry out removal and diagnostics, you must adhere to the following scheme:

A carefully removed car ignition module will help you remove the engine correctly. Due to the fragile nature of the device, do not use excessive physical force. After this, the plug located on the block is dismantled. Only after all the liquid has been drained is the next element removed.

All plugs from the drive are disconnected in random order. The same thing happens with the throttle and hose cables. Before starting this stage, it is better to use a camera to record the initial position. The photo will be useful when the installation of the VAZ engine begins.

Literally, pinpoint precision is required when it comes to removing the hose leading to the gas line. To do this, you need a key set to “17”, which will not break the rather fragile system. Here, as in the case described above, it is necessary to carry out recording using a photo.

When returning the VAZ engine to its rightful place, the photograph will help to correctly connect all the elements. There is no room for error here. Only after you have completed removing all the tubes on the “head” can you move on to those parts that are directly attached to it.

Boosting methods

In most cases, achieving the required indicators is achieved by increasing the volume of the car engine. To accomplish a task of this kind, there are several options:

The first involves increasing the diameter of the cylinder block to accommodate a larger piston diameter by boring. It is called “folk” because of its low cost, because in this case all that requires expenses is the purchase of a set of pistons and wheels, as well as payment for turning services.

The second is to replace the factory crankshaft with one that has a larger crank radius and therefore a larger piston stroke and larger volume. Its cost is much higher than the first method, since you will have to spend money on a crankshaft, a set of pistons suitable for the new crankshaft (since the height of the cylinder block has certain restrictions), and special rings for the pistons. In addition, it will be necessary to pay for work related to block boring.

For many, it may be surprising that the increased displacement of the “nine” engine is not always the most advantageous method of boosting. In some situations (it all depends on what the engine should ultimately be like), it is much easier and more efficient to modify the cylinder head (cylinder head) and then install a suitable camshaft. This type of boost will also make it possible to increase the power performance of the power unit.

Of course, to maximize all the capabilities and reserves of the camshaft, a fairly serious modification of the cylinder head will be required, which may even include repressing the seats and installing valves with a large diameter. For example, engines characterized by the presence of eight valves will fit similar parts from BMW, and sixteen-valve engines will fit components from Opel and Volkswagen. At the same time, one should not lose sight of the intake/exhaust channels intended for circulating the fuel-air mixture - they also require improvement. Their improvement involves increasing the cross-sectional diameter to maximum dimensions through internal polishing.

The technical characteristics of the VAZ 2109 cylinder block, like other components, leave their mark on the overall performance of the engine. You can, of course, study in more detail the influence of the types and shapes of pistons, the weight of crankshafts and much more that is somehow reflected in the operation of the engine, but this article is not about that.

The following characteristics have a particular impact on the performance of the internal combustion engine: the ratio of the length of the connecting rod to the piston stroke and the dimensions of the crankshaft crank (diameter).

The importance of the above parameters is due to the fact that the engine is essentially a pump that pumps a certain amount of mixture through itself over a specific period of time. It is these characteristics that will be discussed further.

Actions requiring increased caution

Remove the muffler and camshaft pulley last. Further actions are taken taking into account the actual situation. If the star bolts are covered with a layer of dirt and oil, then there is no need to unscrew them. Remove everything together with the camshaft. It is better to unscrew them if the motor has been used recently.

The front crankshaft pulley will help you remove the engine correctly. To do this, it is recommended to use a folding key. It is installed through the top, not through the bottom. Before using it, it is recommended to switch to speed 4-5. After this, the VAZ engine is more easily subject to normalized physical impact. If the above recommendations do not help ease the movement of the key, you must use the services of an assistant.

One of the assistants gets into the car and presses the brake pedal. In this case, it is easier to remove the front crankshaft pulley. After this, the pipe and the generator bolts located on top are dismantled.

If the transmission bolts show signs of physical wear or significant contamination, it is better to replace them.

In this case, removing the engine will reduce the likelihood of failure in the future. After all, no one knows when the next time a car owner will look under the hood.

When removing the wires from the generator, it is necessary to gradually loosen the fastening of the device itself. The more accurately your hand moves, the less likely it is to get damaged. After this, the “crab” is removed with no less care. It is secured with two bolts, which we remove using a wrench. Before unscrewing the last bolt, the device is slowly moved to the side.

Unscrew the front crankshaft pulley, it is convenient to unscrew it with a spanner, or in other words, with a head, and so that it does not spin, turn on the fifth or fourth speed and ask the assistant to press the brakes, the crankshaft will lock and simply unscrew the pulley bolt.

Preparing for the reverse process

The process is completed by fixing the VAZ engine using a timing belt. It would be a good idea to use 1-2 bricks to help prevent the engine from falling. After making sure that the massive unit is fixed in space, the cushion is loosened and the engine is directly removed. Having secured the belt with your hand, you need to slowly remove the pipe.

If by this time the engine has not come off on its own, it is recommended to use a pry bar. After this, the unit is transferred to a temporary storage location for subsequent work with it. You need to remember - install everything in exactly the reverse order. If some elements have reached the end of their service life, it is better to replace them in advance.

The process of removing the “heart” of a car is complex and multi-stage. Accuracy and precision of actions is the key to successful repairs on your own. After removal, it is recommended to carry out a mandatory inspection of all engine components.

Oil change features

Filter and plug position

Changing the oil in a VAZ 2109 engine is not the most common process, but you can handle this task as needed. If you buy a used car from another person, you need to change the lubricant in the engine as quickly as possible.

Reinstalling the head

Now you can carefully install the cylinder head in its place, making sure that at this moment the gasket does not slip out or move to the side. Of course, the guides fix it, but you should still be extremely careful.

Next, we will need a torque wrench, since the bolts will have to be tightened with a certain torque. It is also worth keeping in mind that the tightening order must be observed. The diagram below shows the sequence in which to twist:

Now regarding the force with which it is necessary to tighten the bolts. This should be done in 4 steps:

First, a torque of 20 Nm
Second reception with a torque of 75-85 Nm
Tighten each bolt another 90 degrees.
Finally turn it 90 degrees.

What to put?

Indeed, the most important issue among VAZ 2109 owners is the range of engines that may be under the hood of their car.

Let's look at several popular solutions that are most often found among those who decide to change the engine on their VAZ 2109.

Option

Peculiarities

Gas is a cheaper alternative to gasoline, which will allow you to save big in the future at gas stations. This replacement is called the easiest. But you should take into account the fact that such a replacement will pay off only if the car is used frequently, and you will have a gas cylinder in the trunk. Such work can only be done by specialists with appropriate qualifications and permits.

VAZ injector 1.5 liters

A good alternative that will allow you to extract more power from your improved car. The injector is more powerful, it requires less fuel, and provides better dynamics. But in practice, changing engines from VAZ to VAZ is not the best solution, since there are many options among more reliable, powerful imported cars
