Crankcase protection is a very important item when it comes to protecting the main components of your vehicle. It protects the engine and other parts of the machine from damage. The device itself can be either metal or durable plastic. Here are some protection features:
- The crankcase protection serves as a barrier against mechanical damage to the main components located under the bottom of the machine.
- Anti-corrosion function. Rain, snow, as well as powder on icy roads negatively affect the condition of the underbody of the car, causing corrosion. Crankcase protection on the Lada Granta allows you to prevent premature corrosion, protecting important components of the car. It itself is powder coated and treated with an anti-corrosion agent.
- Machine safety. Thanks to the stiffening ribs that the crankcase protection has, it will be impossible for ill-wishers to get close to the main components of the car.
How to install crankcase protection
HomeVAZ 2110How to install crankcase protection
Installing a good crankcase protection will protect the units from damage on our roads, but can it also cause harm? Let's try to understand this issue. Should I install crankcase protection or not? And if so, which one is preferable?
Most manufacturers equip their cars only with plastic engine crankcase protection. In fact, it protects only from dirt, and not from mechanical impact. Some auto giants still install some kind of metal protection, but there are also those who do not install anything at all.
Engine crankcase protection
The market offers a wide range of different protection options.
The market offers a wide range of different protection options.
The market for non-original additional equipment comes to the aid of owners who need complete protection of their units. It happens that for one car model there are as many as six different protection options available. The other side of the coin is that this equipment is not certified by the automakers themselves.
At the official level, they say that the installation of such protections can affect the passive safety of the car in collisions and the temperature conditions under the hood. In the first case, human lives are at risk, and in the second, there is a risk of overheating and engine or gearbox failure. In this case, everything will depend on the specific car model, that is, its design features.
For some, additional protection can play a significant negative role, for others - not.
In fact, the automakers are absolutely right, but the whole situation is governed by the word “may.” No one has conducted crash tests of cars with additional protection or any full-fledged studies on their effect on the operation of engines or gearboxes. In practice, there are no statistics that could confirm the negative impact of such additional equipment.
Crash test
Carrying out crash tests is an expensive proposition. The cost of a full-fledged study of changes in the nature of damage with non-original crankcase protection and without it lies in a different plane.
Carrying out crash tests is an expensive proposition. The cost of a full-fledged study of changes in the nature of damage with non-original crankcase protection and without it lies in a different plane.
In theory, additional protection certainly affects the distribution and absorption of impact energy throughout the power structure of the car and can lead to the fact that the engine will not be able to go under the car. However, no practical confirmation of this can be found in any body shop. There is also no consistent relationship that additional protection aggravates the consequences of an accident.
Non-standard engine crankcase protection, of course, affects the temperature regime under the hood, or more precisely, the aerodynamic air flows. Theoretically, its installation can worsen the cooling of the engine and gearbox.
After all, its shape and location of the ventilation holes (if any) differ from the factory boot. However, in reality, there is no statistical evidence of possible harm on this issue.
Failures of units due to overheating are mainly associated with their design flaws or malfunctions of the cooling system itself.
Engine
Today, it is not engines, but automatic transmissions that are most sensitive to temperature conditions. The gearboxes are packed with a large number of gears into very compact housings, a step that requires a high-performance cooling system.
Today, it is not engines, but automatic transmissions that are most sensitive to temperature conditions. The gearboxes are packed with a large number of gears into very compact housings, a step that requires a high-performance cooling system.
The practice of official dealers, who themselves offer the installation of non-original protections, sometimes even several types, also plays against the position of automakers.
It is difficult to imagine that in this situation the client would be denied warranty repair of units, the malfunction of which could theoretically be affected by the introduction of such additional equipment.
Therefore, if you are afraid of possible problems, but you still need protection, but are running out of money, then buy and install on the side one of its types, which is offered by the dealer. In the event of a warranty claim, no one will look at where it was installed for you.
Remember, the mere fact of having non-original protection is not a reason to refuse warranty repairs, for example, due to engine overheating. A cause-and-effect relationship still needs to be established.
On some car models, the standard boot is a solid sheet of plastic with scanty ventilation holes or no ventilation holes at all. In this case, installing metal or composite protection will not change the climate under the hood at all.
Dressing room
The market offers three types of crankcase guards: steel, aluminum and composite. At the same time, variations in shape and thickness are also possible for the same car.
Steel crankcase protection
Steel crankcase protection is the most popular product that has the most attractive price.
Steel crankcase protection is the most popular product that has the most attractive price.
The most budget-friendly are steel options. Unfortunately, they are heavy and provide the least protection. The degree of deformation is the most significant of the trio.
Composite engine protection
The fewer ribs a composite protection has, the higher its strength characteristics - tested on benches. They are only additional voltage concentrators. Therefore, do not chase a beautiful appearance.
The fewer ribs a composite protection has, the higher its strength characteristics - tested on benches. They are only additional voltage concentrators. Therefore, do not chase a beautiful appearance.
In approximately the same price range, which is almost twice the steel level, are aluminum and composite options.
The latter type has the lowest weight with similar strength characteristics to the aluminum version.
Unfortunately, under certain impacts, the composite material cracks and breaks down, and the protection will have to be thrown away. But the aluminum analogue can still be straightened and installed again.
Aluminum crankcase guard
Aluminum crankcase protection costs a lot of money. But it is durable, lightweight and can be restored.
Aluminum crankcase protection costs a lot of money. But it is durable, lightweight and can be restored.
Mounting options for different types of protection may differ significantly. Some can be removed and installed when changing the oil in a couple of minutes, while others will require much more time. All other things being equal, it is better to choose the option that will have the simplest and most reliable fasteners. This is where the experience of other owners will come to the rescue.
Otherwise, you will have to constantly resort to intricate techniques when removing and installing, so as not to break soured fasteners, which can be extremely poorly positioned.
Sometimes there are protections with technological windows under the drain plugs and the oil filter, but more often than not it is easier to dismantle such protection, so as not to have to wipe off the oil that has spread over it for a long time and persistently.
Steel
Steel is the most common material used in the production of oil pans for quite a long time.
pros
The main advantages of steel protection are:
- fairly simple recovery after a strong blow - straightening;
- high rigidity;
- low price.
Steel pallet
Minuses
- However, in addition to the undoubted advantages, there are also several disadvantages, the main one of which is corrosion.
- Poorly made pallets can resonate strongly while driving, creating unpleasant sounds.
- Sometimes the protection touches the crankcase of the power unit, and this can cause holes to appear through which oil begins to flow.
- The weight of the protective sheet is very large, sometimes it can reach up to fifteen kilograms.
- Significantly reduces ground clearance, as a result of which the car, on rough terrain, can, as drivers say, “lie to the bottom.”
- Incorrectly made or incorrectly installed steel protection very often prevents the motor from running away, thereby creating a danger during a collision.
How to install crankcase protection on Lada Kalina 2?
Many cars, in particular the Lada Kalina Cross, are already equipped with crankcase protection at the factory, but, much to our chagrin, in most cases it is not strong enough and rather serves as a decorative element.
There are protection options available for almost any model, the price of which depends on the material from which it is made.
As a rule, experienced car enthusiasts immediately after purchasing a car replace the factory protection with a new one.

All about crankcase protection
The crankcase protection is a fairly simple design whose main purpose is to minimize or completely prevent damage to the crankcase, which is located at the lowest point of the body.
Protection is a necessary part in any car and is produced separately for each vehicle. Negative environmental influences, possible impacts, dirt and dampness are what await your car during any trip.
Engine crankcase protection
Many models have special protective wings, which, in addition to mechanical damage, will help keep the protected units clean.
A fairly successful solution can be called special shock absorbers of the mounts, which not only soften the blows, but also reduce the noise of the system.
Good crankcase protection not only does not reduce ground clearance, but also improves aerodynamics.
This unit does not require maintenance; it is enough just to check during a routine inspection to see if dirt has accumulated underneath it and if rust has appeared if the protective sheet is made of metal sheet.
Installation is quite simple and does not require much time; drivers usually cope with it themselves.
This video shows the correct installation of the crankcase guard.
Functions
Main functions of engine crankcase protection Lada Kalina:
- protection against mechanical damage to the lower part of the engine;
- prevents the entry of dirt and moisture;
- prevents access to alarm units, which are usually located below;
- protects wiring, connectors, air conditioning pipes, timing belts from moisture and oxidation;
- improves aerodynamic characteristics, which makes the car more economical.
What requirements must it meet?
Probably, after all, the main requirement for engine protection on the Lada Kalina can be called its rigidity. It must withstand and protect the components in the event of a collision with any obstacle or stone. Possible deformation of the sheet should not reach the crankcase.
Also, after installing the sheet, the ground clearance should not decrease, or if this is unavoidable, the decrease should be no more than two centimeters. Otherwise, the protection will very often cling to even the most insignificant obstacles.
The installed sheet should not become an obstacle in the event of a frontal collision and should allow the engine to go down. This is essential for the safety of the driver and front passenger.
A large number of different tech. holes significantly reduces the strength of the engine. But at the same time, they are necessary, for example, so that you can change the oil without dismantling the protective sheet. Ventilation holes must be provided to prevent crankcase overheating.
Technological holes
The sheet can only be attached to elements that have sufficient strength - primarily the beam, engine subframe and spar.
The maximum weight of protection should not be more than fifteen kilograms, but it is desirable that it be even less.
It is important that special damping pads are used to secure the structure. If they are not included in the kit, then you probably need to purchase them separately.
Types of protection
Most often, car underbody protection sheets are made of structural steel. It has a number of advantages when compared with sheets made from other materials.
First of all, it is necessary to note its low price, as well as durability. If for some reason the sheet was deformed, it can be easily straightened by removing it even in normal garage conditions.
The negative point is, of course, a lot of weight.
Protection made of aluminum is much lighter than metal, but is not inferior in strength. However, for various reasons, protective aluminum sheets do not provide for the presence of stiffeners.
Plastic protection is the lightest, but among its main disadvantages is that it can break if hit with sufficient force. It is also worth noting that the term plastic can mean various materials:
- fiberglass;
- carbon;
- Kevlar.

Installation instructions
Installing a protective sheet on a Lada Kalina is quite simple and any car enthusiast can handle it independently within half an hour. Since you will have to work with the lower part of the car, you will need a hole or overpass.
Tools
To install or replace a sheet on a Lada Kalina, we will need the simplest tools that any car enthusiast has:
- ratchet wrench;
- extension;
- set of heads.

Stages
Sequence of unscrewing bolts
- Having reached the bottom of the car, if there is an old factory protection (the so-called boot), then the first thing you need to do is remove it.
- We begin dismantling by unscrewing the front bolts, then the side bolts and then the rear. When removing the protection, think about how to support it or invite a partner, since after unscrewing the last bolt, the sheet may fall on you.
- Now we need to install a new one. To do this, apply a sheet and begin to tighten the bolts.
- Don't tighten them too much right away.
- First bait them, and then walk around in a circle and tighten everything until it stops.
- It is worth noting that some types of protection may require different fastenings and therefore may require other tools.

Video “Defense of Kalina 2”
This video shows the installed engine protection on a Lada Kalina 2 car.
Main selection criteria
The main requirement for protection is rigidity. If the protective pallet is made of flexible material, then even a moderate impact can have catastrophic consequences. The impact through such protection will go into the crankcase, causing its damage. Such protection is simply meaningless.
If you decide to install a metal protective tray, make sure that its thickness is at least 3 millimeters. Otherwise, the sheet will simply not be able to withstand possible impacts.
A very important factor is the weight of the protection. It must be remembered that when designing a designer, they clearly calculate the weight distribution of the body. This means that any load on the suspension can upset the proportions specified by the manufacturer.
SUV with protection
You should not lose attention to such an important factor as safety during a traffic accident. The protective pan should not affect the body deformation model envisaged by the designers.
Another important point worth paying attention to is noiselessness. As a rule, noise occurs when the pan comes into contact with the subframe and all this can be heard very well in the cabin when driving.
When choosing protection for your car, be sure to follow these recommendations and be sure to take into account 4 main parameters:
- high rigidity;
- as little weight as possible;
- safety during a collision;
- silent while driving.
Self-installation of crankcase protection on a Lada Granta car
As you know, bad roads can be merciless to vehicles. Regular off-road driving not only kills the chassis, but can also harm the engine. In this case, installing a crankcase protection would be a reasonable solution. You will find below how to do this correctly on a Lada Granta car with a traditional body and a liftback, as well as a video of installation of the crankcase protection.
Crankcase protection function
Engine crankcase protection for the Lada Granta liftback is an important attribute of the vehicle. It is a structure made of metal or plastic and is designed to protect the engine and other components of the car from mechanical damage. Main functions of crankcase protection:
Additional strength is guaranteed by stiffening ribs. With the protection installed, the owner of a Lada Grant has no need to fear theft, because attackers will be blocked from accessing the main components of the vehicle.
They are provided thanks to a special powder coating, which is typical for most design models. If everything is opened with Movil and treated with an anti-corrosion agent, and such a design is used, you don’t have to worry about the safety of the metal.
If you decide to purchase and install this element on your car, then you need to know something about the material. Such elements can be made of stainless steel or composite materials. Less commonly found on the market are plastic structures. They are absolutely ineffective and in most cases are installed on cars on the assembly line as a gift.
When choosing, you need to focus on the hardness of the material. The tougher it is, the more reliably your engine will be protected. With minimal rigidity, the structure can bend or crack even with a minor impact.
Installation
This process is not labor-intensive; even a beginner in this matter can handle it. In fact, this procedure takes no more than twenty minutes. Therefore, it should not cause any special difficulties, especially since you will see in the video how this is done. But in order to do everything at once, you should prepare in advance.
What will be needed for replacement?
Actually, to replace the element you only need a set of wrenches, no other tools are needed.
Also, of course, you will need the structure itself that you will install. For Lada Granta cars, crankcase protection from Kalina is perfect.
But keep in mind that it is different for automatic and manual transmissions. Therefore, consider this factor before purchasing.
New protective structure for the Lada Granta engine crankcase
Step by step work
So let's get started with the installation:
If you are uncomfortable, then lift the front of the car on a jack and remove both wheels. But if you put the front of the Lada Granta on a jack, then before you begin installing the structure, place supports under the car. In this case, ordinary bricks will do.
You may already have standard factory engine protection installed. If this is the case, then take a wrench and unscrew all the screws around the perimeter that secure it and dismantle the structure. Clean the lower part of the motor from dirt and dust, if necessary, treat with an anti-corrosion agent to prevent rust.
Now all that remains is to install the new structure. It is attached very easily, it is quite possible to do it yourself. Take the same bolts on which the factory design was installed and screw your purchased crankcase protection onto the bottom of the Lada Granta with their help. On the rear side, which is closer to the interior, the structure can be attached to the lever supports. On the front side it is attached to the so-called crabs.
Actually, this completes the procedure. You can learn more about installation from the video provided below.
And remember that using low-quality material in the future can only harm the car. For example, if you purchase a structure made of plastic, then know that it will not be as reliable as a metal one. Of course, the salesperson in the store will tell you about all the advantages of plastic structures, that they supposedly do not rust, and so on.
But in fact, plastic is one of the most unreliable materials, no matter how durable it is.
If, with a strong impact from the bottom, the metal device bends only a little, then the plastic one can not only crack, but also shatter into pieces.
And if this happens, then, unfortunately, there are no guarantees that the plastic piece will not get stuck in some pipe of the cooling system.
Therefore, draw conclusions and do not buy the cheapest products. More details about the installation are shown in the video.

How to remove engine protection on a Lada Kalina: photo and video
Often, Lada Kalina owners need to dismantle the engine protection. This is mainly due to incidental repair operations. But not all motorists know how to do this correctly. In this article, we will look at the reasons why it is necessary to dismantle the protection, as well as the process of how to do it correctly.
Video on dismantling the engine protection:
Reasons for dismantling

There are quite a few reasons why it is necessary to remove the engine protection (also called crankcase protection or engine splash guard). Some Kalina owners don’t even know why and why dismantling is necessary.
So, let's look at the main reasons why engine protection is removed:
So, the main reasons have been considered, and you can begin the preparation process.
What you need
To dismantle and install the engine protection, you will need a Phillips screwdriver and a 10mm socket (wrench). When the tools are prepared, you can proceed directly to the process, which will take an average of 10 minutes.
Unprotection process
Dismantling the Lada Kalina engine protection takes place in a pit or a lift, so you should worry about the availability of such a place in advance. It is advisable that the machine is cooled down, since one careless movement can lead to a burn.

So, let's proceed directly to the removal process itself.
Raise the car and find the mounting bolts. There should be six of them, as indicated in the photo.
The places where the bolts (screws) are located for securing the standard protection of the Lada Kalina engine are shown.
This is how you can easily and simply dismantle standard engine protection in 5-10 minutes.
Refinement and tuning

Many manufacturers offer a wide range of additional protective equipment that will make it possible to protect the motor.
Installed additional protection for Kalina
However, to install it you will need to make additional holes for mounting. But, this is done easily, using a drill and a drill. To cut the thread, you should use a standard 10-point tap. It is bolted to the body side members.

conclusions
Removing the engine protection on the Lada Kalina is quite easy and will only take 10 minutes. To complete the operation, you will need a minimum set of tools, which are found in almost any garage.
Installing crankcase protection on Lada Kalina 2
The AvtoVAZ company has revised its directions and started producing the new Kalina 2 with crankcase protection. When a car owner purchases a car and looks at this protection in his garage, he sees that it is not protection, but just some kind of boot less than 1 millimeter thick.
Some car dealerships themselves offer to install full-fledged crankcase protection, while others, on the contrary, discourage this. The choice always remains with the car owner.
However, if you decide to replace the standard protection, do not be tempted by the inexpensive price of Chinese analogues: it is better to choose the best option in terms of quality and price in the Autocharm online store, which will last a long time and actually perform its functions. Let's remember all the pros and cons of installing crankcase protection.
Pros:
– When hitting various obstacles, the engine crankcase protection takes on most of the loads;
– Small protection from dust and dirt of the engine and other units in the engine compartment.
Minuses:
– The ground clearance of a car with crankcase protection is slightly reduced (by 2-3 cm);
– In the event of a frontal collision, the protection may prevent the engine and other elements of the engine compartment from moving correctly;
– When performing maintenance at service stations, they charge an additional fee for removing and installing protection;
– The protection may catch on obstacles on the road and damage the suspension and body parts.
There are a lot of disadvantages, but the main advantage is also very noticeable, so every owner of Lada Kalina 2 must make an independent choice.
Selecting crankcase protection
If you have already decided to install this element, then you need to choose the right engine crankcase protection. Now on Kalina 2 you can safely install protection from the previous generation, which also suits Grant.
Different manufacturers offer approximately the same protection models, which have minor differences in design. The main thing in protection is the thickness of the metal. The best option is considered to be a crankcase protection with a thickness of 2-2.5 mm, but more “powerful” options can be found.
Let us remind you that in the previous article we told you how to remove the front bumper on Kalina 2 with your own hands. I recommend paying attention to this article; there are various problems on the road.
Installing engine crankcase protection on Lada Kalina 2
To install the protection, you need to remove the standard boot or, after modifying it, install two protections at once. The last option is not the easiest, although it has certain advantages.
These two photos clearly show that the standard part is much thinner than the new one.
We install the protection in place of the old boot and rejoice at the result.
Do-it-yourself installation of crankcase protection on the Lada Kalina 2 engine has been successfully completed. It is worth noting that the price for crankcase protection starts from 1000 rubles.
Grant crankcase protection
Nowadays, cars from domestic manufacturers are not very common on our roads. But in fact, some of them can compete with foreign cars in many respects, because they were produced specifically taking into account the condition of Russian roads. One of these cars is the Lada Granta.
This is a reliable and comfortable car that can easily withstand all the difficulties of our climate and road conditions. It is designed so that every element and system in it can perform its task as best as possible. But some parts that are not included in the factory configuration are nevertheless a necessity.
One of these parts is the engine crankcase protection.
Crankcase protection is needed to protect the engine sump from hitting rocks when driving over bumps and uneven road surfaces, as well as from water, dirt, dust, etc. getting into it.
Grant's engine protection will allow you to avoid unnecessary costs for repairing the car: it is durable and reliable, since it is made of thick steel, which is coated with a special polymer film. And the stiffening ribs provide additional strength, while the weight of the protection remains light.
Moreover, in this way you can protect not only the crankcase, but also other vulnerable areas of the car.
Installing crankcase protection for Lada Granta
Many Granta car owners prefer to service their car themselves.
However, even official dealers note that although it is quite simple to install the Grant engine crankcase protection, it is still better to entrust this to professionals who know exactly what and how to do so that the protection works properly. Installation of engine crankcase protection on Grant model cars is carried out as follows:
- They put protection on top of the standard boot - but not only for the sake of making it easy to remove and put back on. This also gives the engine additional protection from road dust and dirt.
- First you need to unscrew the bolts that secure the boot to the bottom of the car. They begin to install the protection system from its rear points, which are fixed to the boot.
- Then they install the front part of the crankcase protection, screwing it with bolts and securing it with nuts and a wrench.
