Lada Granta - replacing the coolant - Behind the wheel magazine

According to the manufacturer's instructions, replacing antifreeze in Lada Granta cars should be done after 75,000 km or five years from the date the car was put into operation. When making a decision, you should focus on whichever indicator comes first. A prerequisite is periodic monitoring of the condition of the coolant. If the antifreeze color turns orange, replacement is also required.

What antifreeze is best to pour into the Lada Granta cooling system?

The manufacturer recommends using ethylene glycol-based working fluids that do not contain silicates, nitrates, amines, borates and other elements (obtained using hybrid organoacid technology).

To replace antifreeze you will need 7.6-7.8 liters. The most recommended brands of coolants for Lada Grants include:

Antifreeze series Sintec.
Happy TS.
Cool Stream Premium and Standard.
Felix Carbox.
Antifreeze G-Energy and others.

Replacement process

Prepare tools and equipment to replace antifreeze. To successfully complete the job, you will need a thirteen-size wrench, a screwdriver, an empty container (drained, time expired, composition), a clean rag and new coolant. You can buy two 5-liter jars or get a 10-liter jar.

Before starting work, in compliance with safety regulations, allow the engine to cool down to avoid burns during work. Next, relieve the pressure in the cooling system by unscrewing the cap of the expansion tank.

The next step is to remove the engine cover to get to the drain holes. To disassemble the part, you need to unscrew three bolts on the left side, two on the right side, four fastenings in the front and two more in the back. To turn all the bolts, you will need a figure eight wrench. After loosening the bolts, remove the casing and set it aside.

Now let's see how to drain the antifreeze. Do this:

Place a container (6 liters or larger) under the intended drain point. Approximately the drain plug is located at the bottom of the right radiator tank.
Tighten the expansion tank cap securely. This is necessary to reduce the drainage activity of the working fluid at the initial stage and to avoid splashing of antifreeze.
Unscrew the cap covering the drain hole. At this point, wait for the coolant to completely drain from the system and exit into the replacement container. Beware of traffic jams. A rubber ring is installed on its extreme part. If it is deformed or damaged, replace it.

If the engine has 8 valves

Before draining the antifreeze from the jacket of the Lada Granta cooling system complete with an 8-valve engine and gearbox, place a container under the drain hole (located in the front part of the cylinder block, below the level of installation of the ignition coil). Now we take the head at “thirteen” and use it to unscrew the drain plug. As in the previous case, wait until the coolant is removed from the system.

If the engine has 16 valves

If the Lada Granta has a 16-valve engine and a cable gearbox, access to the exhaust port will be blocked by the starter. If you do not remove this unit, during the draining process the coolant will inevitably rise onto it and disable it. To avoid problems, you will need to disassemble the starter before draining the antifreeze.

To do this, follow these steps:

Discard the negative from the car battery to prevent a short circuit in the system.
Press the cable lock latch and push it out of the connector and into the traction relay.
Remove the protective cap from the lock nut of the end of the cable going to the “plus” of the battery.
Use a thirteen-size wrench to unscrew the nut.
Remove the wire tip that fits the traction relay contact bolt.
We take a thirteen key and use it to unscrew the three bolts holding the starter.
Remove the starter.

Now unscrew the cap and drain the antifreeze that is in the cylinder block.

Then screw the plugs into both drain holes. Please note that the cap has a special (tapered) thread that closes the cylinder block. Thanks to this device, no additional gaskets are required. The optimal force for pulling out the drain plug on the cylinder block is 25-30 N * m.

Fill with new antifreeze and remove air plugs

After completing the process of replacing antifreeze on the Lada Grant, proceed as follows:

Pour the prepared coolant into the system until it is completely full.
Start the engine and, after starting it, press firmly on all system pipes several times. This approach removes excess air that may have entered during the replacement process.
Monitor the coolant level in the expansion tank.
As soon as the amount of antifreeze decreases, add it to the upper level (MAX).
Screw on the tank cap.

During the engine warm-up period, the lower pipe, which is connected to the main radiator, will be cold, but after a few minutes it will warm up. As soon as this happened, we can say that the coolant went in a large circle. Now wait for the radiator fan to turn on and turn off the engine. Wait until the engine temperature drops, then look into the expansion tank again. If the level falls below the permissible level, add the working composition to the required level.

Be sure to reassemble all removed parts, including the crankcase guard.

Knowing how to drain the antifreeze and properly fill the system with new coolant, you can do the work yourself and avoid visiting the gas station. The replacement process will take no more than half an hour. At the same time, you will be sure that you have filled in the coolant efficiently and completed all the necessary procedures to remove excess air from the system.

Cars of the Lada Granta family with an injector are pre-installed with a closed liquid cooling system. Antifreeze is forced to circulate through the system, performing two functions: removing excess heat and lubricating the units.

The rated operating temperature of the cooling system is 94 - 99 ℃, regardless of the actual machine configuration, body type and other technical specifications.

How to remove air from the Granta cooling system

Allow the engine to cool.
Unscrew the expansion tank cap.
Start the engine and let it run for 3-5 minutes.
Close the tank lid.
To better fill the system without air locks, periodically squeeze the radiator hoses by hand.

By the way, do you know what kind of antifreeze is poured into the Granta?

It is recommended to change the coolant every 75 thousand km or every 5 years (whichever comes first). You will need about 8 liters of new fluid.

The manufacturer recommends using antifreeze as a coolant based on ethylene glycol, which does not contain silicates, borates, nitrates and amines. The coolant should only be changed when the engine is cool to avoid getting burned.

Also avoid contact of the liquid with skin as it is toxic.

After new fluid is poured into the system, be sure to tightly close the expansion tank cap. Starting the engine with the plug open is prohibited.

After unscrewing all the indicated bolts and screws, remove the middle mudguard of the engine compartment.

We place a wide container with a volume of at least 6 liters under the drain hole made in the lower part of the right radiator tank. To reduce the intensity of liquid drainage at the initial moment, the cap of the expansion tank should be tightly screwed on.

Clutch and brake sensors

Based on the signals from the clutch pedal position sensor and the brake light switch, the controller distinguishes between pressed and unpressed pedal positions. When the clutch pedal is pressed, the controller disables engine load regulation. Both sensors are located on the pedal assembly.

See "Replacing and Inspecting the Clutch Pedal Sensor" and "Replacing and Inspecting the Brake Pedal Sensor."

Some vehicle versions use an electronic throttle valve drive (E-gas). Let us remind you that in order to understand what errors are recorded in the ECU, you need to decipher them.

Coolant temperature sensor for Lada Granta

If a failure or incorrect operation of the coolant temperature sensor occurs, there will be difficulties in starting the engine in the cold season

You have to warm up the engine by maintaining speed with the accelerator pedal.

When overheating occurs, power decreases significantly and detonation occurs.

Removal and inspection

Drain the coolant. You don’t have to drain all the liquid, but drain about 3 liters.

Release the clamp of the wiring harness block and disconnect the block from the sensor.

We connect the “negative” engine voltage probe.

Turning on the ignition, use a voltmeter to measure the voltage at terminal 1 of the wiring harness block (the terminal designations are marked on the wiring harness block).

The voltage at the output must be at least 12 V.

If the voltage does not reach the block or it is less than 12 V, it means that the battery is discharged, the power circuit is faulty, or the ECU is faulty.

When the voltage measurement is complete, turn off the ignition.

Use a 19 mm spanner to unscrew the temperature sensor

Remove the sensor from the thermostat housing.

The connection between the sensor and the thermostat is sealed with a copper washer.

We connect an ohmmeter to the sensor terminals.

To connect a multimeter, pieces of polyvinyl chloride tube can be placed on the sensor terminals.

Insert the probes of the device into them; this must be done carefully, since the sensor leads are very thin.

We fill the container with boiling water, immerse the working part of the sensor in water and record the readings of the device.

As the water cools, we measure the resistance of the sensor at different temperatures.

If conditions permit, readings can be taken at a lower temperature.

The resistance of a working sensor is approximately as shown in the table:

Cooling temperature liquid(°c)	Resistance, Ohm
100	175
90	240
40	1460
10	5670
9420

We replace the faulty sensor.

Installation

Install the sensor in the reverse order of removal.

Fill the engine cooling system with liquid.

We start the engine and make sure that there are no coolant leaks from under the sensor.

If necessary, tighten the sensor into the thermostat housing.

If the leak cannot be eliminated in this way, you should reinstall the sensor by applying a heat-resistant sealant to its threaded part or replace the copper washer.

On a vehicle with a 16-valve engine equipped with a cable-driven gearbox, access to the drain hole in the cylinder block is prevented by the starter.
In addition, the leaking liquid will inevitably get inside the starter. On a vehicle with a 16-valve engine equipped with a cable-driven gearbox, access to the drain hole in the cylinder block is prevented by the starter. In addition, the leaking liquid will inevitably get inside the starter.

Therefore, the starter needs to be removed. Disconnect the wire terminal from the negative terminal of the battery. By pressing the latch of the wire block, disconnect the block from the traction relay connector. Remove the protective cap from the nut securing the tip of the wire connected to the positive cable of the battery.

Grant engine temperature sensor. install it yourself

Every owner of a Lada Granta car has encountered its main drawback - the absence of an engine temperature sensor on the panel.
The task of the AvtoVAZ management was to make Grant accessible, the engineers did it “excellently”, saving even on this device. The emphasis was on cheapness, so we tried. Soon, however, everything was corrected - on models of a higher price and advanced configuration of the Lada Granta liftback 21911, 21912, 21917, an engine temperature sensor has already appeared and helps monitor the condition of the internal combustion engine.

However, what should owners of earlier models do? The overheating indicator lamp installed on cars is not informative enough.

In winter, it is impossible to determine whether the engine is warm enough to start driving, and in summer, the overheating warning light may come on too late.

The thermostat is the weak point of Lada Granta cars, and it would be much more effective to determine its malfunction at a very early stage by assessing the behavior of the TD sensor needle, but...

It was these problems that prompted some motorists to look for answers to the question: “How to install an engine temperature sensor on a Grant?” You can, of course, contact dealers. For a fee, specialists will equip everything you need. But there's no need to rush.

First, you should purchase an installation kit for the coolant temperature sensor (engine). If you don’t want to go to a car store far, or don’t want to, you can easily order the necessary kit in an online store with home delivery. It includes:

temperature indicator,
plastic case for it,
the sensor itself;
fastening clamps.

Once you have the kit in your hands, it's time to head to the car. To see the place where the Grant engine temperature sensor will be attached, the negative terminal is removed from the car battery, and behind it the air filter is disconnected and removed.

This will open an overview of the pipe that leads from the thermostat. Coolant circulates through it during operation.

It is necessary to carefully cut the pipe and insert the temperature sensor inside along with the adapter (buy at a car store), then securely tighten it with clamps.

The wires are dealt with as follows: the first is the ground wire, it is attached to the engine (body), the second is pulled directly into the cabin.

An indicator with an arrow for the temperature sensor can be installed on the dashboard near the windshield next to the instrument panel. Visually this is very convenient, because... It is located close to eye level, and a quick glance will be enough to control the temperature level.

But what should you do if you may need to fix the navigator in approximately this place? The second option for mounting the sensor indicator is even more aesthetically pleasing.

Many motorists install the device in a cup holder next to the gearbox, but the panel itself will need to be slightly modified.

Of course, in this case you will have to look for a place for a glass of coffee, but this will be a huge plus: the sensor indicator in your cabin looks very harmonious. Now you can fully control the engine temperature and monitor how the thermostat behaves.

There is an easier way to solve the problem of the missing coolant temperature indicator. You just need to buy a bluetooth adapter elem 327.

We unscrew the plug as shown above and drain the coolant from the cylinder block.

We tighten the drain plugs of the radiator and cylinder block. The connection between the plug and the cylinder block uses a conical thread that does not require additional sealing. Tighten the drain plug of the cylinder block to a torque of 25–30 Nm. Pour liquid into the engine cooling system through the expansion tank until it is full. Let's start the engine. With the engine running, vigorously compress all the hoses of the cooling system several times in turn - this will help the fluid fill the system and displace air from it. As the coolant level in the expansion tank drops, bring it to normal and screw on the tank cap. When the engine warms up, the outlet (lower) radiator hose should be cold for some time, and then quickly heat up, which will indicate the beginning of fluid circulation in a large circle. After waiting for the cooling system fan to turn on, stop the engine. After the engine has cooled, check the coolant level again and, if necessary, replenish the system.

5.	Ignat: In order for the machine to work properly and the parts to last longer, it needs to be looked after, looked after, and maintained.
6.	Dmitry: Six months have passed since the purchase of the car, so far the work is perfect, there are no investments except for the purchase of consumables.
7.	Valentin: I am satisfied with the build quality of domestic transport; breakdowns do occur, but they are unimportant and can be easily repaired. The engineers managed to combine good quality with an affordable price.
Negative
1.	Ivan: bad experience in operating the car, the thermostat had already jammed at 45,000, after which the bearing fell off. The model is still rough, there are many shortcomings, and the manufacturer is not trying to quickly eliminate them.
2.	Vladimir: the build quality is low, after two months of using the machine, the rubber hose broke and the antifreeze leaked.
3.	Vyacheslav: Lada Granta or Renault Logan - obviously the latter. The manufacturing quality of the French automobile industry is an order of magnitude higher than the national one.

Production As practice shows, most calls to service stations are related to a jammed thermostat on the Lada Grant. The reasons are different. The factor of manufacturing defects cannot be ruled out, but the car owner is also to blame.

Buy original spare parts, repair your car in a timely manner, then the number of breakdowns will be reduced significantly.

Coolant replacement should be performed as part of maintenance. It changes every 75,000 kilometers or 5 years, whichever comes first. Today we will tell you how to replace antifreeze with your own hands.

Final works

The last step in replacing antifreeze on a Lada Kalina will be to replace the ignition module, connect wires to it, and check all plugs and connections for leaks.
Next, start the engine and check the result of the work. To do this, you need to wait until the engine warms up and the Carlson starts working. Then we check the operation of the heater to ensure that hot air is blowing into the cabin; if it blows warm air, this means that an air lock has formed in the system.
It is also necessary to take into account the fact that when the engine cools down, it is necessary to recheck the coolant level and, if necessary, add it.

Possibility of mixing different types of liquid

The answer to this question is very simple and short; you cannot mix any antifreeze or different types.

This can result in some hard or jelly-like deposits that can clog the cooling system passages.

In addition, as a result of mixing, foaming of the cooling solution may occur, which can lead to overheating of power units and very serious consequences and expensive repairs.

Choices

When choosing, do not neglect the color of the liquid. The color is intended to indicate certain properties of the antifreeze, so replace it only with an option with an identical color.

Recommended brands of antifreeze include the following products:

“AGA 003Z” (temperature minus 40 degrees), has a red color, costs approximately 1 thousand rubles. for a 10 liter container.
“Professional Premium” belongs to the “G-12” category, and the cost of a similar “tank” reaches 700 rubles.
“SINTEC LUX G-12” is also characterized by a red tint and costs from 1 thousand rubles. for a volume of 10 liters.
“FELIX Carbox-40”, a canister of the same volume with red liquid will cost the owner from 950 rubles.
"NIAGARA", substance "G12"; for a volume of 10 liters you will need to pay at least 800 rubles.
“Arctic Circle”, a substance with similar parameters; A 10-liter container costs at least 700 rubles.

Antifreeze from the above-mentioned manufacturers has proven itself quite well, so you can purchase it without the slightest hint of doubt.

How often should this be done?

There is a general recommendation regarding how often antifreeze should be changed. It is recommended to change the refrigerant at least once every 2 years, or after 30 - 45 thousand km of vehicle mileage. The frequency of replacing “Antifreeze” must be observed taking into account the following indicators: the condition of the car, its mileage, the brand, manufacturer and composition of the coolant itself, as well as the solution used previously. Products with silicate-based additives need to be changed every 2-3 years. Hybrid fluids lose their properties after 3-5 years, and carboxylate antifreezes can “work” without replacement for 5 or more years.

How to remove air from the Granta cooling system

Allow the engine to cool.
Unscrew the expansion tank cap.
Start the engine and let it run for 3-5 minutes.
Close the tank lid.
To better fill the system without air locks, periodically squeeze the radiator hoses by hand.

By the way, do you know what kind of antifreeze is poured into the Granta?

To avoid engine overheating, the owner of a Lada Kalina is recommended to constantly monitor the level of antifreeze in the cooling circuit. For this purpose, there are special marks on the body of the expansion tank. The level should not be below the minimum and above the maximum. If there is a gradual decrease in the amount of antifreeze, then there is a high probability that a fluid leak will appear. In Lada Kalina, such hot spots can be areas connecting pipes to the radiator, tank or thermostat, as well as the pump gasket. In this article we will talk about how to drain antifreeze, as well as how to replace coolant in a car.

How to properly replace antifreeze on a Lada?

Replacing antifreeze is a routine procedure that must be carried out when operating any car. Should I use the services of a workshop or replace it myself? This question arises for every novice driver. After reading this article, you will be able to independently select the necessary coolant, prepare the car for replacement and safely replace antifreeze. Instructions for flushing the cooling system are also provided.
