Replacing coolant on 2ZZ-GE

Antifreeze is a car coolant because its freezing point is lower than the freezing point of water. Antifreeze is designed to prevent damage to parts caused by the expansion of water when it freezes. Antifreeze not only has a lower freezing point, but when frozen, it forms a mushy mass, the formation of which does not damage engine parts, although it does not allow the engine to operate normally.

Drain the coolant. Note: To reduce the risk of burns, do not remove the reservoir cap while the engine and radiator are still hot, as liquid and steam may escape under pressure. Remove the radiator support cover. Remove the radiator cap. Fill with coolant. Tighten the radiator drain plug and pour coolant into the radiator until it begins to overflow. Volume: 6.7 l (7.1 us qts, 5.9 imp. qts). Advice:

Compress the radiator inlet and outlet hoses with force several times. If the coolant level has dropped, add coolant.

Tighten the radiator cap. Fill the reservoir with engine coolant until the “full” line is reached. Warm up the engine until the thermostat valve opens. Tip: While warming up, squeeze the radiator inlet and outlet hoses with force several times. Stop the engine and wait until the coolant temperature drops. Next, remove the radiator cap and check the coolant level. If the level has dropped, then perform the above procedures again. If the level does not drop, adjust the coolant level in the reservoir. Check for engine coolant leaks. Fill the radiator with coolant and attach the radiator cap tester. Pump the tester until the pressure reaches 118 kpa (1.2 kgf/cm2, 17.1 psi) and check for leaks.

The pump on the VAZ 2110 is a pump that distils coolant. This is an important element of the engine cooling system. The device is necessary for pumping coolant, which ensures coolant circulation through the circuits.

The structural elements of the pump are:

Bearing;
Impeller;
Frame;
Drive gears.

On a VAZ 2110, the pump is located to the right of the cylinder block in the direction of travel under the timing belt cover. The pump operates by rotating the timing belt, which drives the drive gear.

Pump location

On the VAZ 2110/11/12 the water pump is located on the cylinder block on the right side. This is due to the design features of the gas distribution mechanism, since the impeller begins to rotate only after the engine and timing belt are started. That is, the design of the gas distribution mechanism initially involves the use of a pump.

The water pump is part of the timing mechanism and is installed on the right side of the cylinder block

Breakdown and signs

There are several characteristic signs based on which you can recognize the failure of the coolant pump:

A hum or a rustling sound appears near the timing drive;
There are traces of coolant leakage from the pump seat;
Mechanical damage occurred to the belt - cracked, delaminated, teeth broke;
The engine began to overheat excessively;
The coolant level drops below normal, even when topping up;
Liquid does not circulate well through the system.

Most often the pump fails due to bearing failure. It, in turn, breaks due to wear or incorrect installation of the timing belt tension. If such problems are found, the pump must be completely replaced.

Consequences of ignoring

If you ignore a pump breakdown and do not take any action to repair or replace it, this can lead to dire consequences. Namely:

The timing belt is damaged or broken. It will then have to be repaired, the cylinder head, gas distribution mechanism, and piston group must be replaced;
The motor is overheating. Because of this, all rubber connection elements of the engine cooling system, cylinder head gasket, valve cover, and rubber components of the piston group can be destroyed.

Replacement

Having purchased a new coolant pump, you can begin the replacement procedure.

The VAZ 2110 works in conjunction with 8 valve and 16 valve power units. Despite there being a certain difference between them, the pump replacement procedure is identical.

Dismantling works

The instructions below are relevant for dozens with two types of motors.

Place the car on a level area above a hole or on an overpass.
Lift the hood, remove the negative terminal from the battery, which will turn off the power to the car.
Unscrew the cap of the coolant expansion tank. This will relieve excess pressure in the system.
Now get down under the car.
Place a clean container with a volume of at least 5 liters under the cylinder block.
Unscrew the coolant drain plug using a 13mm wrench, which will allow you to drain the coolant. Be careful, unlike oil, you need to drain the coolant when the engine is cool.
When all the coolant is out, screw the plug back into place.
Using a 10mm wrench, unscrew the three mounting bolts that hold the timing case in place.
Remove the casing.
Place the crankshaft at TDC of the first cylinder - top dead center. To do this, you need to turn off the gear and turn the special bolt that holds the generator pulley to 19 with a key. Turn until the marks on the camshaft gear align with the mark on the rear timing case.
Make sure that the marks on the flywheel and clutch housing match. To do this, you will have to remove the plug on the crankcase. It is made of rubber and is located to the right of the cylinder block.
Lock the crankshaft in this position. You can use a simple slotted screwdriver that fits into the teeth of the flywheel.
Slightly loosen the tension roller locking nut using a 17mm wrench.
Turn the roller using a special wrench in a counterclockwise direction. This way you can loosen the tension level of the timing belt.
Now you can quite easily dismantle the tension roller and belt.
The next step is to remove the five mounting bolts that hold the lower timing case in place. These include 3 bolts that hold the pump. You will need a socket wrench or a 10mm socket.
The casing can then be removed.
The VAZ 2110 provides for installation of a pump using three hexagon bolts. Once you unscrew them, you can simply carefully remove the pump by tapping on the body.
If that doesn't work, then use a flathead screwdriver to pry up the coolant pump housing, which will allow you to remove the pump.
Remove traces of the old gasket that should remain on the surfaces of the seats.

Changing the gasket

The gasket is lubricated on both sides using a special automotive sealant. The prepared and processed new gasket is placed on the body of the new pump.
The new pump is installed in its rightful place, taking the baton from the old coolant supercharger.

Signs of a pump malfunction

Thanks to the rotation of the pump driven by the timing belt, the impeller circulates a special fluid (antifreeze, antifreeze) through the small and large circuits of the cooling system. A damaged pump can cause the engine to overheat or cause the timing belt to break. To avoid an emergency on the road, you should do preventive repairs on time. On a VAZ 2110 with an 8-valve engine, the omen of replacing the pump can be recognized by the symptoms described below.

Noise from the timing belt cover

When the engine is running, a shuffling rotating sound is produced from the side of the timing belt protective cover. This is an indication that the pump bearings are sufficiently worn. According to the maintenance regulations, the pump should be changed every second timing belt replacement. The recommendation should not be neglected, since the rolling shaft bearings operate under load and wear out relatively quickly. Sometimes antifreeze or antifreeze gets into the bearing race due to a leaky seal. As a result, the lubricant is washed out and wear of rubbing parts accelerates.

Coolant leak from under the pump

Hermetic seals: the oil seal and rubber cuffs, as well as the bearings, have a limited service life. Typically, seals leak after bearings wear out, as there is play in the shaft. In addition to this, the constant cycle of heating and cooling of the engine gradually destroys the material of rubber products. As a result, small puddles of coolant appear under the engine compartment of the VAZ 2110 on the pump side.

Misalignment of drive shaft pulleys

A defective pump can result in noisy engine operation and frequent timing belt breaks. According to the performance characteristics, skewed rotation of the pulleys does not provide the vehicle with a long service life. The belt cannot withstand additional loads and breaks after a mileage of up to 1000 km. As a result, you will have to replace the defective pump, otherwise on such a VAZ 2110, an unscheduled replacement of the timing belt will become a regular procedure.

Motor overheating

The pump impeller may be partially destroyed. The lack of blades leads to a decrease in coolant circulation. As a result, the engine does not receive proper cooling from the small circuit and the temperature rises, even to the point of boiling. Overheating, in turn, has a detrimental effect on the engine.

Among the most common consequences, the most difficult to eliminate should be listed:

can “drive” the cylinder head;
the cylinder head gasket burns out;
piston rings are destroyed;
the motor risks jamming;
The crankshaft bearings fail.

For reference! Frequent use of a special sealant to eliminate coolant leaks reduces the service life of the water pump. The foreign mixture tends to stick to the impeller, forming a solid clot and clogging the channels of the cooling jacket.

How to check the pump

Usually, a broken pump immediately reveals itself with a pungent smell of antifreeze in the cabin. This indicates that the seal is broken and the coolant is leaking out. In advanced cases, antifreeze can form a puddle, which indicates complete wear.

In addition to direct signs of malfunction, there are also indirect ones:

Motor overheating. This is especially noticeable in winter, when in principle it should not overheat. You can check it visually: warm up the car and turn on the heater. If cold air comes out, it means the pump is leaking and you need to check the water pump.
Timing belt wear. The pump has a guide bearing that holds the belt. Its wear leads to misalignment, which tilts the belt slightly and grinds the teeth unevenly.

Please note that replacing the VAZ 2114 and 2115 pump with 8 valves is required every 70,000-100,000 km - this resource was provided by the manufacturer.

Which pump to choose

There is no need to save money on purchasing the main coolant unit. Today the market is saturated with various types of pumps, with any pricing policy. For VAZ 2110 car owners who decide to replace the pump with their own hands for the first time, auto repair shop experts recommend paying attention to branded manufacturers such as: KolbenShmidt, SKF, GRAF, HEPU, Valeo, Quinton Hazell. It is not recommended to install: FEBI, Dolz, RUVILLE, Airtex, Pex.

Choosing a pump for your car

So, you have decided to replace the pump. Now you need to go to the auto store and buy the required element. However, sellers offer a huge assortment of different water pumps for the VAZ 2110/2112 - which pump to choose so as not to go wrong with the price and quality?

The price of a pump for an 8-valve VAZ 2110/2112 engine is from 800 rubles, for a 16-valve engine - from 1 thousand rubles. However, regardless of the cost and brightness of the packaging, when purchasing, you must pay attention to the following details:

manufacturer (take products only from companies that you know well);
the pump has its own catalog number (for example, the standard VAZ pump in all catalogs in car stores and on Internet sites is numbered 21081307010);
the pump is sold in clean, uncreased packaging;
The kit includes a gasket;
A factory quality guarantee is provided with the pump.

Car enthusiasts prefer a pump produced by TZA. A water pump from a domestic manufacturer is easy to install, lasts a long time and is inexpensive. However, there is a risk of purchasing a defective product.

Replacing the pump

After preparatory steps, such as: searching for a garage box (if you don’t have one for personal use), preparing keys (open-end sockets), purchasing spare parts and coolant, you can get to work.

To explain as briefly and clearly as possible how to change the pump on a VAZ 2110, we will describe the process in the form of step-by-step instructions:

It is advisable to install the machine above the inspection hole. As an option, an overpass is suitable;
It is recommended to carry out plumbing work on a de-energized car, so you should unscrew the negative terminal from the battery;
remove the expansion tank cap, this will prevent the formation of a vacuum in the cooling system;
A 5-liter container (at least) should be installed under the engine to drain the coolant, since it is recommended to change the pump when the antifreeze or antifreeze on the VAZ 2110 is almost completely drained. Otherwise, when the pump is removed from its seat, the contents of the system will spill out randomly;
On the back of the block there is a coolant jacket plug, which should be unscrewed with a 13 mm wrench and the liquid should be drained into a container placed under the engine. Screw the plug back;
Next, you should unscrew the timing drive casing (with a 10 mm wrench), secured with three bolts;
disconnect the casing and set it aside;
it is necessary to set the gas distribution mechanism to the top dead center according to the marks. Having moved the gearshift lever into neutral, rotate the camshaft gear by the mounting bolt (19 mm wrench) until the marks on the inner timing drive casing align;
you have to check the mark on the flywheel: remove the rubber plug in the upper part of the crankcase on the right side of the engine and shine a flashlight into the opening;
the correct position should be fixed by inserting a metal rod or a powerful screwdriver into the camshaft gear;
loosen the roller nut (17mm wrench) and use a tension wrench to turn the roller mechanism counterclockwise, reducing the belt tension;
Next, remove the belt and roller;
unscrew the bolts of the internal timing drive casing (2 pieces) and the pump bolts (3 pieces). It is more convenient to work with a 10 mm socket wrench (head);
remove the casing and put it aside;
use a slotted screwdriver to pry up the edge of the pump and pull it out of its seat;
The installation site must be cleaned before installing a new pump;
a new pump gasket can be lubricated on both sides with a thin layer of high-temperature automotive sealant;
insert the new pump into the seat and tighten the mounting bolts;
Next, you need to return the dismantled parts to their place, observing the reverse order. After installing a new kit: pump, belt and timing pulley, you can count on a certain service life of the parts declared by the manufacturer.

Important! Do not tighten the timing belt too much. It’s easy to check the correct tension: the installed belt can be turned 90° with your fingers (with the teeth facing out), but no more.

After final assembly, it is necessary to fill the system with coolant to the specified level. We start the engine and warm it up to operating temperature. All hoses should be hot, and when they are compressed, the hand will feel internal circulation. This is an indicator of the correct operation of the cooling system.

Why do you need a pump in a car?

If we talk about the operation of a car engine, then we immediately touch upon the topic of its cooling. Indeed, without high-quality cooling, the engine will not be able to work for a long time and will definitely “boil”. Thanks to the circulation of coolant, it becomes possible to operate the engine at any time of the year under any external conditions.

The power component on the VAZ of the tenth family has a rather complex structure. During the working cycle, the pistons rub strongly against each other, which invariably leads to strong heating of the surfaces. The only way to prevent engine overheating is to constantly maintain the desired temperature in the friction zone through the circulation of coolant and. It is for this purpose that the VAZ design includes a cooling system.

The design and operating features of the VAZ 2110 engine cooling system are described in detail in this material: https://vazweb.ru/desyatka/dvigatel/sistema-ohlazhdeniya-dvigatelya.html

Coolant (antifreeze or antifreeze) is poured by the driver into the expansion tank of the car. From it, the liquid is transferred through pipes to the water pump, and from there it goes to the radiator and cylinder block. The water pump (or pump) is designed to pump antifreeze through the system while the engine is running. That is, the pump starts together with the engine and turns off after the driver turns off the car. Without a pump, the entire cooling system can be considered ineffective, since only the pump can create rapid circulation of liquid throughout all parts of the system.

The pump is designed to create the necessary pressure in the cooling system to move the liquid.
