The easiest way to replace the timing belt, pulley and pump on a Lada Granta with an 87 hp 8-valve engine

The cooling system integrated into the power unit of the popular domestic bestseller Lada Granta, which has 8 valves, has a traditional design. Among the most important components of this unit is a pump. Modifications of the engines offered in terms of equipment for the Granta are endowed with the following factory designations:

• "VAZ-11183";
• "VAZ-11186";
• “VAZ-21126” (similar for automatic transmission);
• "VAZ-21127".

The pump must be replaced correctly; its selection should be made based on catalog data. Correct selection of parts is a very important aspect of engine safety, since the “safety” of the timing belt depends on the pump (its functionality). Well, which pump to choose is ultimately up to you.

Next, we will clarify the catalog code of the component in question. It looks like this: 21114-1307010-00 or 21114-1307010-01.

You can check the amount of wear of the product and the need for its replacement by manual manipulation. To do this, you can limit yourself to visual observation. If such a measure does not bring the desired result, then the element must be dismantled in order to finally verify the presence of breakage or wear. In this case, the pump needs to be replaced.

Next, let’s look at the signs the presence of which “classifies” an element as not being used:

• noise generated by a worn bearing;
• traces of smudges indicating damage to the seal;
• if wear or breakage of the impeller is detected, then this fact will be confirmed by insufficient fluid circulation in the cooling circuit (temperature increase);
• the appearance of axial play on the shaft can also reliably indicate the “death” of the bearing.

All this indicates that the pump needs to be replaced.

Purpose of the water pump

The main function of the water pump is to maintain the timing belt and move antifreeze through the engine cooling system. In turn, the cooling system is designed to ensure the required circulation of antifreeze, cooling the power unit and providing its parts with protection from possible overheating. The lack of cooling makes the normal functioning of the motor impossible, since even minimal loads in this case lead to instant heating and subsequent boiling of the power unit.

The pump operates thanks to the drive from the timing belt. The operation of the entire cooling system is structured as follows: first, coolant is poured into the expansion tank, and after the engine is started, it enters the pump cavity. The pump operates in a temperature range from - 40oC to + 40oC with air humidity up to 90%.

Reinforced pump Luzar for Lada Granta 2190

Luzar Turbo 2 is a high-power water pump for the Lada Granta. The average cost in the Russian Federation is 650 – 750 rubles, depending on the place of purchase. Pump flow rate at 800 rpm is 900 l/h. The unit runs 95 – 120 thousand km.

The installation of a turbo version of the pump is explained by the fact that the engines of the Lada line are prone to rapid boiling and an increase in operating temperature.

The temperature increases according to the following scheme: the car moves at high speeds on the road. A sudden stop at a traffic light provokes a rise in temperature, heat stroke, and boiling of antifreeze.

Symptoms of pump failure

The resource of a modern water pump of a VAZ injection engine averages from 40,000 to 50,000 km. Pump failures caused by its operation are diagnosed quite simply. To determine the causes of the malfunction, you will need to visually inspect the CO section of the water pump, or completely dismantle this section. The most typical symptoms of a malfunction include:

• leaks in the area where the water pump is located;
• the coolant level in the tank drops sharply;
• the motor begins to heat up rapidly;
• At the location of the pump there is noise and humming of the bearings.

Description of the replacement process

Grants are equipped with eight and sixteen-valve engines. The water pump is located under the timing belt casing, and therefore when dismantling it, both casing covers, the belt, the tension roller and the crankshaft pulley are removed. The slight differences in the procedure for changing the pump for an eight- and sixteen-valve power unit lie in the different methods used when dismantling and subsequently installing the timing belt, which will be discussed in more detail below.

The cost of the pump varies from 1000 to 2000 rubles. For 1000 rub. the owner of the Grant will be able to purchase a water pump manufactured at AvtoVAZ. More expensive pumps are imported analogues that have an increased service life. In addition, there are also pumps on the market that cost from 500 to 700 rubles, but most often they are sold by not very conscientious sellers who pass off their product as an original, which it actually is not. Installation of such parts is highly undesirable.

It is also worth noting that when purchasing a new element, the car owner should focus on the type of engine for which this part is intended, since pumps for 8- and 16-valve Grants are not interchangeable. There are markings on the pump packages that allow the buyer to select the part that is suitable for his type of motor.

Instructions for changing the pump on Grant

Even before starting work, the car owner is recommended to read the machine’s operating manual; this will help you study the structure and location of the water pump in more detail. Remember - incorrect reassembly will lead to damage to the antifreeze in the system.

Then you need to prepare a place to work; normally this should be a dry box with a flat floor. Take care of good lighting, this will not only make the process easier, but will also insure you against the loss of small fasteners and small parts.

At the very beginning of work, the car is de-energized by removing the terminals from the battery. In addition, the car is securely secured using parking shoes or a hand brake. All these manipulations are carried out to ensure maximum safety and convenience of the work process.

When replacing, it is extremely important not to deviate from the sequence of actions given below, since violation of the described order of work can cause a breakdown of the cooling system and lead to a fire in the car.

Replacing the pump itself will require you to do the following:

• First you need to completely drain the coolant;
• Next, unscrew the fastening elements and dismantle the front cover of the timing case;
• Then fix the piston of the first cylinder at top dead center;
• The car is put into gear;
• A jack is used to lift the front wheel of a car;
• The wheel rotates until the mark on the pulley coincides with the mark located on the rear timing housing cover;
• Work is being done to dismantle the timing belt, the tensioner pulley is dismantled;
• The rear cover of the timing case is removed;
• The fastening elements securing the water pump are unscrewed;
• The element is carefully pryed off with a screwdriver, after which it is removed;
• In the future, you should install a new pump and previously dismantled elements and assemblies, performing actions similar to dismantling, but in the opposite order.
• Before installing a new pump, the mating surface of the cylinder block is cleaned of the remnants of the previous gasket and a new one is installed in its place, having first applied a thin layer of waterproof sealant to it. The drainage hole on the water pump body should be directed downwards after installation;
• The last stage of the work process involves pouring coolant into the cooling system.
• The liquid is filled to a level 25-30 mm below the maximum mark on the tank, this is approximately 8 liters of antifreeze. The work is done.

Preparatory stage

Required materials and tools:

• set of automotive tools;
• heads, ratchet;
• rags;
• additional lighting;
• screwdrivers with a flat, cross-shaped bit;
• hydraulic jack.

Important! We do not rotate the motor shafts (camshaft and crankshaft) in order to avoid mark failure.

Installing a new timing belt

We take out a freshly purchased set.

Timing kit.

Important! The tensioning direction is indicated on the timing belt tension roller, do not confuse it.

We check that all marks match and install the tension roller; do not tighten the bolt. We install the new timing belt first on the crankshaft sprocket, then on the camshaft, tension roller and pump. The belt section between the camshaft and crankshaft sprockets must be tensioned. Pull the tension roller until the marks match and tighten the bolt.
