Hello! Tell me, please, where from the side of the flywheel (I have a VAZ 2107, engine 1.6) coolant flows in a stream! Are there any stubs there? (Catherine)

Catherine, hello. Many motorists face a similar problem, now we will try to help you.

Causes and methods for determining a leak

To understand why the refrigerant is flowing and solve the problem, you need to understand the reasons. What are the reasons for a possible leakage of consumables? They are listed below.

  1. If the problem appeared during the cold weather, then it may well be associated with cracks in the tank. When the coolant (coolant) is diluted with water, it can freeze at low temperatures, as a result of which the expansion tank will “burst”.
  2. System connections could be depressurized as a result of a slight loosening of the clamps.
  3. The appearance of cracks in the pipes and hoses of the cooling system.
  4. Worn thermostat gasket.
  5. There was a breakdown of the radiator or a malfunction occurred during its operation.
  6. If coolant gets into the engine oil. But this reason is not specific to your problem if the coolant flows from the clutch side. By the way, there can be any plugs there, if you yourself (or the previous owner, the master at the service station) installed them during any work.

How to solve such a problem?

A consumable leak can result from damaged hoses or fittings in the system, or from loose torque on any connections. You can check this quite simply: put a piece of cardboard under your car, specifically in your case, everything is simple - you even know where yours is leaking. After some time, check for coolant stains at the leaks.

It is also desirable to diagnose the condition and junction of the pipe connecting to the radiator. If you see moisture at the junction, then the leak is here. First of all, in this case, the clamp changes. Also, it will not be superfluous to check the sealing gum of the thermostat. As practice shows, such malfunctions sometimes appear as a result of the loss of the sealing properties of the gum.

One of the most common causes is a malfunctioning radiator. A breakdown of this mechanism can be detected by fogged windows in a car, a damp front passenger footboard. If you see a puddle under the rug, you will have to disassemble the part of the cabin in front.

The appearance of an antifreeze leak in the VAZ 2107 cooling system is a serious enough problem to pay attention to it and immediately address it. Leaking coolant can cause overheating and even engine failure.

VAZ 2107 has many places prone to antifreeze leaks:

  • Cooling radiator;
  • Branch pipes and their connections;
  • Water pump or pump;
  • Heater faucet;
  • heater;
  • Cylinder head gasket.

For each of the above places, there are different ways to fix the problem. Naturally, the easiest method is to replace the damaged element. This applies to all possible problems, unless the antifreeze flows at the connection points of the pipes. In this case, replacement is most likely not required, just tighten the clamp.

Radiator of the cooling system

Usually VAZ 2107 cars are equipped with an aluminum radiator, which is not repaired. In this case, only replacing it can solve the problem. If copper is installed in your car, you can try to fix it. This task is unlikely to be within the power of an ordinary motorist, therefore, without hesitation, we entrust repairs to specialists. Before starting work, you will have to drain all the antifreeze from the cooling system, which can be a good reason to replace it. To do this, stock up on coolant in an amount of approximately 9-9.5 liters. Choose a quality fluid that will extend the life of the engine and the main elements of the cooling system.

Heater faucet

Usually a sign that a faucet is leaking is the appearance of a puddle of antifreeze on the rug under the passenger's feet. It is absolutely not advisable to repair this part, so we just buy a new faucet and change it. There is no need to drain all the antifreeze, so after installing a new tap, simply add as much coolant as it leaked during operation.

heater radiator

As in the case of the main VAZ 2107 radiator, its repair is possible provided that it is made of copper. Determining that it is he who is flowing is not as easy as in the case of a faucet. The specific smell of heated antifreeze can help determine the presence of a malfunction. Before removing the radiator, it is necessary to close the tap, then after assembling the cooling system, you will have to add antifreeze exactly as much as you have to pour out during operation.

Diagnosed by visual inspection. Nowadays, repairing a VAZ 2107 pump is not economically feasible, it’s easier to buy a new one and change it. Again, you don’t have to drain all the antifreeze; at the end of the work, add the missing volume to the system.

This is the most unpleasant of the malfunctions, as a result of which antifreeze flows out of the system. If the breakdown is on the outside of the gasket, the leak can be seen with the naked eye on the engine. Worse, if the gasket is pierced near the cylinder. In this case, the defect can be determined by indirect signs - an increase in the oil level in the oil pan, a large amount of water vapor from the exhaust pipe. Regardless of the location of the damage, only the replacement of the gasket can eliminate the identified drawback.


In any of the above cases, one of the signs of a malfunction is a decrease in the coolant level. Having discovered this, you should immediately start looking for the cause. Timely diagnosis and troubleshooting will help to avoid serious troubles with your car.

The appearance of antifreeze in the cabin is always unexpected and unpleasant. Antifreeze under the driver's feet or on the front passenger side, as a rule, indicates a malfunction of the stove radiator. Here we will consider the flow of antifreeze into the passenger compartment using the example of VAZ-2101, VAZ-2102, VAZ-2105, VAZ-2106, VAZ-2107. The elimination of such a problem has almost the same algorithm for other Zhiguli models.

So, find antifreeze in the cabin it is possible due to a rusted stove radiator or a metal pipe, a stove tap. A visual inspection will help determine the exact cause. If the stove tap or pipe is to blame for the problem, then they must be replaced, and you will not have to disassemble the bar panel and radiator casing. If the radiator is still to blame, then the decision depends on its type.

  • an old-style radiator (copper) is subject to repair, it can be soldered, cleaned, etc. The main task here will be to find a good master;
  • the aluminum radiator cannot be repaired, it remains to throw it away and buy a new one.

How to change the stove radiator to stop the flow of antifreeze?

  • Antifreeze can be drained from the engine block, but this procedure is not necessary, because the losses will be small.
  • On the radiator pipes, two clamps are unscrewed from the engine compartment, the hoses are pulled together.
  • The fasteners of the rubber seal are unscrewed and removed.
  • Next, remove the radio panel in the cabin.
  • The fastener of the drive cable is unscrewed and disconnected from the heater tap with the key to "7".
  • Using a screwdriver, remove the four spring clips on the fan casing.
  • We lower the casing itself, moving it to the left. The wires will completely prevent it from being removed.
  • Now you can remove the stove radiator from the casing.

The stove faucet, metal pipes and the radiator itself must be carefully examined. The pipes must be free of corrosion and coolant leakage. The stove tap must be replaced if its handle does not open or close, or if traces of antifreeze leakage are visible.

If you are changing the stove radiator, and the tubes and faucet are in good condition, then it is quite possible to put them on a new radiator. Just do not forget about new gaskets that need to be lubricated with silicone sealant. The drain pipe and faucet are screwed to the radiator quite tightly, but be careful in your efforts, otherwise you can strip the threads or crush the gasket. Silicone sealant is also useful for lubricating the radiator tube when rubber antifreeze supply hoses are attached to them.

If the VAZ 2107 pump is leaking, it is not recommended to drive such a car for a long time. Of course, it still depends on how strong the leak is - if the liquid drips slightly, then you can postpone the repair. But if antifreeze leaves at a speed of several hundred grams per day, you can not hesitate. It is necessary to carry out repairs as soon as possible, now you will learn how to do it right.

What is a pump?

First, a few words about what a VAZ 2107 pump is and what to expect if it suddenly flows. In fact, this is a conventional liquid pump, which consists of a housing, a rotor, an impeller, a drive pulley. On cars of the classic series, it is driven from the crankshaft using an alternator belt. It is also worth mentioning that on older machines a fan was installed on the drive pulley. But this was at a time when electric radiator fans were not even dreamed of.


What happens if the VAZ 2107 pump is flowing? First, a lot of coolant is lost. Therefore, before each trip, you need to pour antifreeze into the expansion tank. Secondly, heat transfer worsens, and a significant increase in temperature is possible. Thirdly, air pockets may appear, which also cause poor engine cooling.

Replacing the pump VAZ 2107

Before starting work, you will need to completely drain the liquid from the engine cooling system. To do this, you need to unscrew two plugs in turn - on the engine block and at the bottom of the radiator. This is how the VAZ 2107 antifreeze is drained just like that. After waiting for all the antifreeze to merge, you can begin to carry out repairs. First of all, remove the alternator belt, to do this, unscrew the nut on the bracket a little. Please note that the part of the VAZ 2107 liquid pump in which the impeller is located most often changes.


The second half does not contain any specific elements, so the maximum that can happen to it is destruction as a result of mechanical impact (impact) or corrosion. So, to disassemble the pump, you will need to unscrew the bolts securing the pulley to the rotor. Then, using the key on "13", unscrew the nuts that fasten the two halves of the VAZ 2107 pump. Place a flat screwdriver between the halves and disconnect them.

The fact is that it can be problematic to disconnect, since silicone sealant could be used during assembly. In addition, the gasket itself can stick to the case over time. Before installing a new pump, it is necessary to thoroughly clean the surface of the second half, which is installed on the engine. Then install the gasket (new, of course), you can coat it with a thin layer of sealant for reliability. Install the pump in place, screw on the nuts. Tighten them after 5-10 minutes, when the sealant dries a little.

Final stage

And at the end of this epic will be the installation of the alternator belt and the filling of antifreeze into the system. If everything is extremely clear and simple with the belt, then several questions may arise with refueling. One of the main ones is how many liters of antifreeze are in the VAZ 2107, what is the volume of the cooling system?


Often this question interests drivers, as they need to know which canister of liquid to buy in a store. Take 10 liters, this is enough, there will even be a lot left for topping up. The price of an antifreeze canister of this volume will be about 800 rubles. But the price of a liquid called "antifreeze" (green or red) is a hundred rubles more expensive.

And now about how to properly fill the fluid in the VAZ 2107. In particular, this guide will help you even if an emergency or planned fluid change is carried out. So, it is desirable to install the car correctly - the front part is slightly raised.

This is done so that the stove radiator is lower than all other elements of the system. Disconnect the thin tube from the carburetor or throttle (if you have an injector). It comes from the pump, it is necessary to warm up the throttle assembly or carburetor body.

Open the cap on the radiator and expansion tank, make sure the drain plugs are in place and tight. Everything, you can start pouring antifreeze into the radiator. If uncomfortable, use a watering can. How many liters of antifreeze will fit into the VAZ 2107 at this stage is impossible to say for sure. But three to five liters should definitely go in.

Don't rush, let the liquid drain slowly. Squeeze the nozzles with your hands to expel the air as much as possible. When the liquid stops leaving, you need to close the filler neck, pour antifreeze into the expansion tank and start the engine.

Warm up the engine to operating temperature, if necessary, add antifreeze to the expansion tank. Put on a thick cloth glove and carefully crimp the pipes. Air should be escaping into the tank. When the antifreeze comes out of the tube that you disconnected from the throttle, you need to install it in place.


This suggests that the liquid has got into all corners of the system. Only plugs remain relevant. You can get rid of them if you carefully squeeze the pipes on a running and warm engine.

That's all, now the VAZ 2107 pump is not flowing, the system has been pumped and freed from air jams. Now not only will the cooling be perfect, but the heater will start working with maximum efficiency. And for winter this is the most important factor.

The owners of the VAZ 2107, like many other motorists, most often remember the stove in cold weather. Instead of warm air from the nozzles of the heating system, it blows cold. Sometimes a faulty heater creates a different kind of problem. Condensation forms on the windshield, sticky to the touch. And when examining the space under the instrument panel, it turns out that antifreeze has long been getting on the trim and rug.

In order for the repair of the heating system to be carried out quickly and efficiently, it is necessary, first, to determine the cause of the malfunction. In some cases, the heating radiator is absolutely innocent of the problems that have arisen.

The main types of heater malfunctions

The VAZ 2107 stove requires attention for several reasons:

Not warm

The lack of heat in the cabin when the stove is turned on to the maximum position is due to the following malfunctions.

  1. Airing the cooling system when replacing antifreeze or repairing any of the components (thermostat, pump, radiator, etc.). In this case, you just need to remove the air plug, add coolant and enjoy the heat that has appeared.
  2. The heater valve closes the line even in the open position. This is due to clogging or scaling when water is used as the coolant. It is necessary to disassemble the faucet, clean it or replace it.
  3. A cold stove may indicate such a serious breakdown as stopping the water pump. If the inlet pipes to the heater and cooling radiator remain cold, and the engine has already warmed up to operating temperature, then the pump needs to be repaired.
  4. Clogged stove combs are one of the most common problems. It can occur due to the formation of scale or due to oil getting into the antifreeze. The stove can be removed and washed thoroughly. After that, it will still serve as a car owner.
  5. If both pipes connected to the stove are warm, and the heater is cold, then the rubber partition in the radiator may have failed. It is displaced from the seat, creating a direct path from the inlet to the drain. Then the heating radiator will have to be changed.

Antifreeze leaks in the cabin

  1. Antifreeze leaks through the stove faucet. It can be replaced without touching the radiator.
  2. The reason for the leakage of antifreeze may be a burst pipe. Replacing it won't be a big deal either.
  3. The stove radiator could not withstand the pressure in the heating system, and a leak occurred. Only removing the radiator will tell if it can be repaired or if a new heat exchanger is needed.

In any case, repairs should not be delayed, since the ethylene glycol contained in antifreeze is very toxic.

Dismantling the heating radiator

To remove the stove VAZ 2107 you will need:

  • screwdrivers (flat and Phillips),
  • wrenches and end wrenches.

The sequence of actions looks like this.

  1. In the engine compartment, it is necessary to loosen the two clamps that attach the hoses to the stove pipes. When you remove the hoses, some antifreeze will flow out.
  2. Here you need to unscrew the screws of the rubber seal and remove it.
  3. The rest of the operations are performed in the salon. You should start with the radio panel. Usually it is fastened with two self-tapping screws.
  4. Using a 7 mm wrench or a screwdriver, the cable is disconnected from the stove tap.
  5. There are four brackets on the fan casing, which can be removed with a screwdriver.
  6. The casing goes down and is retracted to the pedals. The motor power wires will not allow the cover to be completely removed.
  7. However, there will be enough free space to carefully remove the radiator from under the panel.

Radiator Repair Methods

Depending on the malfunctions found during the inspection in the heating radiator, the best way to solve the problem is selected.

  1. You can try to clean a clogged radiator with a pressure of running water. Remove scale and other deposits will help a special tool that is poured inside for several hours.
  2. If there are leaks in a copper radiator, it is better to contact an experienced shareholder. He may be able to patch up a crack or hole.
  3. Repairing a crack in an aluminum radiator is quite difficult. In this case, it will be easier to replace the heat exchanger.
  4. It is not advisable to use mustard or similar industrial products to seal the radiator. Having eliminated one breakdown (leak), there is a high probability of getting another (clogging).

Assembly and installation of the stove

The assembly and installation of the heating radiator is carried out in the reverse order. You need to pay attention to certain aspects of the work.

  • To a new radiator, you will first have to attach a pipe and a faucet. Rubber gaskets must be replaced. First you need to coat them with silicone sealant. Tighten the nuts should be without fanaticism, so as not to squeeze out the rubber gaskets.
  • After installing the radiator in the casing, it is necessary to seal the outer surface of the metal pipes with sealant. After that, clean hoses are put on them in the engine compartment, and the clamps are clamped.
  • Now you need to add coolant and check the tightness of the connections.
  • The car can be started, not forgetting to observe the dryness of the joints.

When repairing the VAZ 2107 stove, it is necessary to check the serviceability of not only the heating system, but also some components of the cooling system. Only a comprehensive examination will accurately determine the cause of the failure or leakage of the stove. A little time spent in uncomfortable positions is compensated by hot dry air from the heater nozzles.
