The Lada Kalina car, equipped with an injection engine, cannot be called expensive or difficult to maintain. If problems arise, for example, with the exhaust manifold, then everything can be solved on your own.
The exhaust pipe is necessary to collect and redirect exhaust gases to a special exhaust pipe of the muffler. replace the Kalina exhaust manifold at home.
Reasons for removing and replacing the exhaust manifold Lada Kalina
The exhaust manifold is made of cast iron, which is very resistant to temperatures. However, a critical temperature - 800-900 degrees - can render the distributor unusable. In addition, there are many other factors that negatively affect it. This list can include:
- Mechanical damage;
- Loss of tightness at the junction with the cylinder head (cylinder block);
- Inoperative condition of the gasket between the BC head and the manifold;
- Due to constant overheating, cracks or warping may occur.
Sometimes replacing the exhaust manifold on Kalina 8 valves is necessary in order to install a more advanced and high-quality part.
Important! The exhaust manifold gasket is created from pressed reinforced asbestos and is necessary to create a tight connection between the BC head and the distributor. The fact is that the BC head is made of aluminum, and the manifold is made of cast iron. Therefore, under the influence of temperature, these two elements expand and contract differently. And asbestos allows you to coordinate the difference in thermal expansion. The main threat to the gasket is constant exposure to high temperatures.
There are a number of symptoms that will tell you that you need to replace the exhaust manifold of your Lada Kalina:
- In any operating mode, the engine makes an unpleasant characteristic sound;
- Exhaust gases enter under the hood or even into the interior of your car;
- The engine loses power due to a mismatch between the BC head and the manifold.
What does the muffler consist of?
The main part of the exhaust system serves to absorb noise. On the Lada Kalina car, this function is performed by a pipe, which includes the muffler itself and its resonator.
The thickening is the resonator, the end is the muffler itself
The pipe has a completely sealed body, which is manufactured using the rolling method, that is, without the use of a welding machine. Thanks to this, the muffler is durable and does not corrode. And the resonator, which is also located in the pipe, consists of several closed chambers. These chambers are connected to each other by small tubes with holes in them. Thanks to this structure, the resonator can quickly smooth out all acoustic vibrations. In the latest modifications of the Lada Kalina, the inside of the resonator is lined with sound-absorbing material.
Required tools and materials
The list of what is needed is, in principle, standard: a standard set of tools, an extension cord with various heads, WD-40 or other similar lubricant. If you know that the problem is broken studs, then a stud extractor, taps, drill and drill bits will be added to the above list. In addition, a bucket or basin, possibly an old canister, should be at hand.
Advice! A few days before replacing the exhaust manifold, you can begin to lubricate all fasteners in the system. Can be lubricated several times a day. This will greatly simplify the task and make replacement quick.
Dismantling
There is only one difficulty in this process - the inaccessibility of some fasteners. It is best to carry out this “operation” in a viewing hole or on a lift. Of course, this is not necessary, but it is much more convenient.
Work order:
- First you need to remove the negative terminal from the battery or turn off the mains switch.
- Next, it is recommended to drain all the antifreeze into a container prepared in advance.
- Next, you need to disconnect the fuel pipes. If the coolant is not drained, at this stage it will go into the cylinders.
- Now you have to find the throttle position and idle speed sensors, and then remove the wires from them.
- We first remove the crankcase ventilation from the hoses, then the brake booster.
- Remove the intake manifold (receiver) together with the throttle assembly.
- Then remove the fuel rail (without disassembling) and the wires from the injector.
- There's not much left. Now you need to remove the heat reflecting screen. The exhaust pipe of the muffler is unscrewed from the manifold.
- We remove the exhaust manifold Kalina 8 valves from the BC head studs, to do this we unscrew the fastenings shown below in the figure
Installing a spider in a 16-valve car
The sixteen-valve Kalina is equipped with a complex power supply and gas distribution system, so the work carried out will be more labor-intensive. The sequence of actions is as follows:
- removing the terminals from the battery, draining the coolant;
- loosening the clamps securing the air duct pipe and the throttle assembly to the filter;
- the pipe is removed;
- the chip is disconnected from the throttle assembly and oxygen sensor;
- the hose of the crankcase ventilation system is removed;
- the adsorber purge hose is disconnected;
- the receiver mounting bracket is unscrewed;
- the nuts are unscrewed and the receiver is removed;
- unscrew the upper and lower fastening nuts, remove the heat-insulating shield and eye;
- the fastenings of the spacer to the exhaust manifold are twisted;
- the heat shield is removed;
- the intake manifold is dismantled, for which you need to unscrew nine nuts near the block head and three at the exhaust pipe;
- “spider” is mounted;
- the lambda probe wire is extended, a mechanical or electronic snag is installed;
- The elements are assembled in the reverse order.

The catalyst prevents atmospheric pollution with carbon monoxide and other toxic substances. Its service life is not designed for more than 100,000 kilometers of vehicle mileage, so every owner will sooner or later be faced with the need to replace this element. You can replace the catalyst yourself or by contacting a service station.
It is important to remember that inept DIY repairs will aggravate the problem and cause additional costs in the future.
Replacing the exhaust manifold and gasket
When dismantling the manifold, the gasket is destroyed in almost any case. Therefore, it is worth removing its remains from the parts. Replacing the Kalina exhaust manifold gasket is a simple process. The use of sealants and other third-party substances is not recommended. They may later get into the crankcase.
Replacing the manifold itself is simple - just take a new part and install it according to the principle in which it was attached. Assembling the system is simply the reverse order of the steps outlined in the last section.
Advice! Don't forget about cleanliness. This is an important factor in long and trouble-free operation of the car.
Manifold dismantling procedure - step-by-step instructions
The dismantling process itself is not so complicated; access to some nuts is difficult, so it is advisable to carry out the work on a lift or in an inspection pit. The algorithm of actions for the injection VAZ-2114 in this case looks like this:
- Remove the negative terminal from the battery or turn off the mains switch.
Remove the terminal from the battery
Disabling the throttle position sensor
Disconnect the muffler exhaust pipe from the manifold
Removing the exhaust manifold
Replacement of gaskets and installation of manifold
After dismantling the manifold, it is rarely possible to remove the gasket intact. It changes in any case , but parts of the destroyed gasket will definitely remain on the mating plane on the head side and on the manifold side. They must be carefully removed.
After installing new gaskets (they are different for an 8-valve engine and a 16-valve engine) and fixing the manifold, you should make sure that the unit does not come into contact with electrical wiring, hoses, or touch the stabilizer. Good luck to everyone!
