No driver expects his car to suddenly “boil.” This is one of the worst scenarios of the day - you will have to stop and cool the car. Rule out problems in advance - first of all, inspect the Priora pump. If the water pump of a Lada Priora car with a 16-valve engine fails, this will instantly extinguish all the car’s efforts to cool it. In addition, the timing assembly, rollers and pump break down - and this is a disaster for the engine because all these spare parts are dependent on each other. The supplied device works like a pump - it pumps up antifreeze and forces it to flow through the circuit at a certain speed, it manages to “release” the heat it receives from the engine. A pump replacement is needed when the Lada Priora pump breaks down, the coolant “stands up”, accumulating all the heat inside itself and releasing it to the surrounding air with less efficiency. That is why this device should not be allowed to malfunction.
Symptoms of malfunction
- Noise from the pump when the engine is running. Extraneous sound appears due to bearing wear. It is recommended to replace the cooling system pump after one or every replacement of the timing belt kit. If you neglect service intervals, wear appears on the rolling elements, inner and outer races, which leads to noise and whistling. Often the cause of accelerated wear is antifreeze, which, due to a leak in the oil seal or rubber cuff, gets to the rubbing vapors.
- Antifreeze leak. Like the pump bearing, the oil seal and rubber seal have a limited service life. The appearance of play due to bearing wear will significantly increase the risk of seal leakage.
- Misalignment with respect to timing gears and rollers (the pump becomes askew). Uneven tension distribution leads to accelerated wear of not only the bearing, but also the oil seal. Incorrect installation or a manufacturing defect, in which the pulley rotates misaligned, leads to accelerated wear of the loaded part of the belt. Such a defect, even with low mileage, can cause the timing belt to break and the valves to meet the pistons.
- Engine overheating. When the impeller blades break off, the pump's performance decreases, as a result of which less coolant passes through the small circulation circuit.
Often a decrease in performance is noticed after using a sealant to repair a radiator leak. The poured mixture clogs the cooling system channels and sticks to the pump impeller.
If the liquid has not clogged the coolant drain channel in the housing, then pouring sealant will not lead to a malfunction of the water pump. But you can’t do without removing the pump and flushing the system.

mileage 82560...same story. Found smudges on the protection and extraneous sounds. Engine 1.6 16 valves...
good thing I noticed it in time!)
I drove 135 thousand on my pump)))) today damn it started leaking (
I think it's a record holder!)))
At 37,000 km the pump jammed. Moreover, because of the strange sounds, I signed up for a warranty service, but didn’t have time to drive a measly 50 km))) Let’s see, along the way everything got screwed up!
unlucky for you my friend! this is very bad…
An autopsy showed that the belt was intact, but may have jumped 1-2 teeth. Yes, in fact it’s not so important, under warranty they will change everything, even the entire piston part)
Your belt must have sagged and was hitting the casing. That’s why there were sounds. you need to check everything, otherwise if the problem is in the pump, then change everything. Let them change the rollers anyway, you need to look at the belt, it’s 40KKm on the edge!
If the tolerances of the rollers are normal, of course they won’t change them, but I think they can say that they are changed outside of warranty? (The price of two rollers is 3000 rubles)
they don't cost that much...
mileage 80,000 not a hint
