How many motorists there are, there are so many reasons for such an operation as replacing a heater with a VAZ 2114. However, there is no single solution how to fix similar malfunctions.
When a replacement is needed
In what cases is it generally necessary to replace the heater radiator in a VAZ 2114 car:
- Started to leak
- He is trite huddled
Very often, the replacement of a VAZ 2114 heater is accompanied by the owners of this car with an endless obscenity and a lot of time spent. It is not difficult to change the radiator of the stove with your own hands, but it is quite difficult to get to it.
So, what you need to stock up on:
- Knowledge (for interest, at least read the murzilka)
- A set of all kinds of screwdrivers, it is better if short
- You can study such material as replacing the heater stove VAZ 2114 video
- And the most important thing is to have patience, which you will need in this matter in immeasurable quantities.
Everyone changes in different ways, someone who removes the panel completely, who performs such an operation as replacing the heater without removing the panel of the VAZ 2114, who drains the coolant, and someone simply puts plugs in the pipes (of course, it would be better to drain so that do not stain the interior or take a shower of antifreeze or antifreeze) and it’s not so hard if you have a mixer hose at hand. In this case, we will consider the method without removing the panel.
Work order
Before starting work, you should generously anoint your hands with some kind of cream (it will be easier to wash them later, and cuts are possible in this process) and you can start this laborious process.
So:
- We drain the coolant (if your coolant is hermetically sealed, then the expansion tank cover should be closed, after instead of plugging the hose into the engine, open the cover and the coolant will gently flow into the container prepared in advance).
- Then you need to remove the glove compartment and side panels, in this case you need to unscrew all the fastening screws that you see.
- Also, do not forget and unscrew the fasteners to the floor - there are two screws on the sides, on the left and right sides of the panel. Then we unscrew the fastening screws that secure the cables (on the left and right sides), these screws on the driver's side also hold the radiator cover, there should be three of them.
- You need to make sure again and check if all the screws and bolts are unscrewed (do not forget to unscrew the two self-tapping screws located closer to the passenger's door and the one that is installed in the upper right corner on the panel, it is located near the buttons and is closed with a plug). Gently pull the panel towards ourselves.
We substitute some kind of block or a plastic bottle into the gap formed between the panel and the frame on the passenger side.
- We unscrew two clamps from the radiator, do not forget to substitute some container under the pipes so that the interior is not flooded with coolant. There is still a sufficient amount of coolant in the system, so do not rush to remove the container.
In order to drain the coolant to the end, you can remove and put on the pipes. You can see this process in more detail in the photo.
So, they drained all the liquid, pulled off the clamps, the radiator slightly crawls out and rests on the lower part of the panel. In this matter, one cannot cope, one must lift the panel, and the other at this time pull out the radiator, the same algorithm is used during assembly.
So:
- We take a new heater radiator, and as the instructions show, everything is assembled in the reverse order. It is also necessary to understand that you should not save on the heater radiator, and buy the model whose price will cause laughter, believe me, it will not last long and this difficult procedure will have to be repeated again.
It is better to buy a high-quality heater radiator once and not have any problems with it for many years.
The most difficult thing in this matter is to remove the radiator, and then it can be blown out with compressed air to clean, solder or even change. Also, during the installation process, pay attention to the nozzles, if they need to be replaced, then do it right away, while everything is open and accessible.
If it does not work on your car, then this is a disaster, regardless of the time of year. Car windows fog up even from the driver's breath, and especially from the breath of passengers who have celebrated something.
As a rule, opaque glass is an immediate threat to safety, in short, it is necessary to replace the heater fan or replace the heater electric motor with a VAZ 2114 on a VAZ 2114 car, in any case, both operations are carried out in the same way.
Execution order
VAZ 2114 begins by disconnecting the negative terminal of the wire from the corresponding terminal on the battery.
So:
- Under the dashboard in the passenger compartment, we disconnect the "positive" wire connector, which goes to the electric motor and, having unscrewed the front nut of the heater fastener to the body, remove the "earth" terminal of the electric motor from the stud.
- Then, to carry out such an operation as replacing the VAZ 2114 heater fan, we turn off the five self-tapping screws for fastening the air inlet grilles with a Phillips screwdriver.
- Remove the right and left air inlet grilles.
- Using a Phillips screwdriver, unscrew the four self-tapping screws of the protective casing and take out the protective casing itself.
- Then, using the same Phillips screwdriver, unscrew the two screws securing the fan to the heater housing.
- Pull the wires of the electric motor through the rubber seal. We remove the heater fan from the air intake box.
- We remove the casing seal. Then, using a flat screwdriver, pry on the latches and separate the casing into two parts.
- Having released the two fastening brackets, remove the cover from the fan motor and take out the motor along with the wheel.
Caution: To avoid imbalance, do not remove the fan wheel from the motor shaft. This is where the replacement of the VAZ 2114 heater motor ends.
In the reverse order, we carry out the installation and assembly of the heater fan. The seal should be glued with a universal glue.
Replacing the heater switch on a VAZ 2114
It should be noted right away that replacing the VAZ 2114 heater switch is not a difficult job, but very inconvenient and painstaking. For greater convenience, you can also remove the dashboard and drain the coolant completely, but you can do everything without this.
In order to replace the stove tap, we need:
- Key for 10
- Rags
- Coolant
- Worm clamp with a diameter of 16-23 mm
- New heater tap
- Empty containers with a volume of 5 liters or more
- Crosshead screwdriver.
How to replace the stove tap on a VAZ 2114
The first step is to unscrew the side wall on the passenger side of the central instrument panel or remove the panel completely - at your discretion.
So:
- We put rags under the feet of the passenger and under the faucet so that spilled drops of liquid are absorbed.
- We open the hood and unscrew the clamps of the outlet and supply hoses of the stove, remove the pipes from the faucet and drain the liquid into an empty container.
- Then, in the passenger compartment, using a Phillips screwdriver, unscrew the fastening clamps securing the heater pipes to the faucet and disconnect them. We substitute the container to drain the coolant.
- Using the pliers, remove the bracket from the pull of the faucet lever and remove it from the hole of the lever.
- Then we return to the engine compartment again and, using a key for 10, unscrew the 2 crane fasteners of the heater to the dashboard.
- And again we return to the salon and take out the tap.
Install a new faucet in the reverse order:
- We install a new faucet in its place.
- We fix it from the engine compartment with two nuts (it is recommended to pre-lubricate them with anticorrosive.
- Fully open the cock on the side of the passenger compartment and tighten the bracket.
- Then we put on the pipes from the side of the engine compartment and the side of the passenger compartment, we fix them well.
- If it was completely drained, then we fill in the coolant, or on the throttle assembly we unscrew the pipe and until then we fill the liquid into the tube until it is full.
- We install the pipe in place, start the car, warm it up, tighten the clamps on the tap pipes and turn on the stove.
If cold air is blowing from the stove, then most likely there is air in the stove radiator. To eliminate this problem, it will be necessary to expel air.
This completes the procedure for replacing the stove faucet, screw the dashboard into place and you can ride.
