Many owners of the five have tried and are trying to improve the heating system of their car. And not always only a complete replacement of the VAZ 2105 heater is the only right decision.
Often on a VAZ 2105, replacing the heater tap or other alterations is of great benefit. For example, you can independently seal the joints of the air outlet hoses or redistribute the air flows, but still, this does not give great efficiency.
Replacing the heater tap vaz 2105
Replacing the heater tap with a VAZ 2105 and other improvements are aimed only at maximizing the operation of the stove. As mentioned above, this replacement is carried out due to the improvement and modernization of the stove (you can put a ceramic version) or if when the old tap starts to leak.
A tap leak can bring a lot of trouble to the car owner. Therefore, eliminating the leak will be the only correct solution, and this can only be done by replacing the valve.
Advice. We purchase a heater stove faucet in a store, preferably with two pipes.
It should be noted that the selection of cranes is huge today. Nevertheless, experts and experienced drivers advise buying a ceramic faucet. It has a better package than the regular one.
There are many details in it.
You will need:
- Rubber rings.
- Fastening nuts.
- Washers.
- Aluminium case.
- Ceramic filling and more.
Ceramic faucets last much longer than conventional metal ones. They practically do not stick like ordinary ones.
We begin the replacement, armed with a jack, spanners and wrenches, heads and an extension cord. We lift the car to the inspection pit, which will greatly facilitate the work process.
Getting started:
- we take any container and substitute it under the engine;
- unscrew the plug on the block, and then drain the coolant;
- after that we remove the container, but not far, since it will still be needed;
- we find the pipes that go from the motor to the heater tap;
- we dissolve the clamps of the pipes;
- we take a metal brush and clean the threaded connections of the two studs.
Advice. To avoid problems with loosening the nuts, it is recommended to wet the connections with brake fluid. After all, studs are not ordinary bolts, but parts, the caps of which are buried in the plastic body of the crane.
The fastening nuts of the caps are self-locking and have plastic rings that are difficult to unscrew. And also, if we add corrosion to this, then everything becomes clear.
We continue:
- we remove the nozzles while the threaded connections are turned off (remember that you need to put a container under the nozzles, since liquid flows from there);
- go to the salon;
- remove the side panel of the torpedo;
- then we find the pipe clamps;
- we take a socket wrench with a cardan and unscrew the clamps;
- remove the pipes and replace them with new ones;
- after removing all the pipes, we climb under the car again;
- we find the nuts fixing the heater tap;
- unscrew them with a 10 key;
- we return to the salon;
- we pull the crane towards ourselves;
- remove the spring clip;
- disconnect the control cable from the crane;
- we install a new heater valve, first connecting the cable and attaching the valve to the body.
That's all! A new heater tap is installed.
The rest of the assembly is carried out in reverse order.
Radiator and heater fan
You should be aware that in order for the interior of the car of the five to always be warm and comfortable, especially on winter days, it is necessary to be able to increase the amount of supplied heat. And which part is directly responsible for the supply of warm air?
The radiator, of course. But there is a problem - there is such a fan on the top five that it takes laughter.
It is very small and simply not capable of creating the required flow.
What to do? First, let's compare the fans on the VAZ 2105 and on the VAZ 2108.
The first motor consumes 4.5 A of current and has a rotational speed of 3000 rpm, and the second 14 A, but turns 4100 rpm. This already says something.
It is recommended to replace the fan with another one.
Replacing the heater fan vaz 2105
Replacing the heater fan with a VAZ 2105 is carried out as follows:
- the lower part of the stove is removed (this is a simple casing, on top of which a conventional electric fan is installed);
- the old fan is removed;
- we cut off one of the aerodynamic ridges that supply air to the legs of the driver and passenger (this is done due to the fact that the VAZ 2108 fan motor is much longer);
- the impeller is also removed, which will not allow the fan from the VAZ 2108 to sit in place;
- instead, a homemade one is put.
Advice. In order not to remove the impeller, but to leave everything as it is, you can use another fan.
A standard five-blade fan for a classic is suitable, with a motor several times more powerful. And its weight is much lighter, and the rotor of the new motor rotates stronger than even that of the VAZ 2108.
We continue:
- we increase the diameter of the impeller hole;
- we put a new shaft there (we do it very carefully so as not to break the impeller);
- we connect the fan and check its operation;
- we adjust the resistor and collect everything in reverse order.
Replacing the heater VAZ 2105
What does the stove consist of?
Before starting the replacement, it is useful to familiarize yourself with the design of the Vaz 2105 stove.
It consists of:
- bracket for control levers;
- air duct for internal ventilation;
- special control levers;
- air duct for heating the side windows;
- from flexible rods;
- from a clamping clamp;
- rubber hoses;
- crane;
- branch pipe seal;
- air duct damper;
- air distribution cover.
Removal and installation
If you decide to completely replace the stove, then this is done as follows:
- the ground wire is disconnected from the battery;
- the instrument panel and the receiver panel are removed;
- the heater tap control lever is moved all the way to the right;
- the coolant is drained from the heating system;
- the clamping clamps are loosened;
- the rubber hoses are disconnected from the heater pipes (they control the supply and discharge of fluid);
- the seal is removed (it is recommended to watch a detailed video before removing);
- two bolts fixing the bracket are unscrewed (they are located inside the engine compartments);
- the bolts of the fastening brackets are loosened;
- the rods are disconnected and the bracket is removed;
- remove the nozzles on the left and right;
- nut fixing the right air duct for heating the side windows;
- the left air duct is removed in the same way;
- we find four spring-type holders and remove them;
- we also remove the heater fan casing assembly;
- the nuts securing the radiator casing are unscrewed;
- the wire under the ground is disconnected and the casing is removed;
- the air duct is removed;
- the old heater is removed;
- a new heater is installed in reverse order (photo below).
Advice. When installing the heater, pay attention to the installation of the sealing gasket.
It is located between the vehicle body and the radiator shroud. Also, adjust the heater control during installation.
You can do a lot with your own hands in a way that no specialist can do. The step-by-step instructions given above will help novice motorists do everything on their own.
In addition, you can save a lot, because the price of these services is high today.
