Engine VAZ-11189
Content
AvtoVAZ engineers have replenished the line of eight-valve engines with another successful model. The designed power unit in a short time became in demand among motorists.
Description
The VAZ-11189 engine was created in 2016. For the first time it was positioned at the Moscow motor show in the car Lada Largus. The issue was mastered by the VAZ automobile plant in Togliatti.
The ICE in question is an improved copy of the successfully proven VAZ-11186. Looking ahead a little, I would like to note that the new version of the motor turned out to be improved and refined in comparison with the previous model.
VAZ-11189 - four-cylinder gasoline aspirated 1,6-liter, 87 hp. with and a torque of 140 Nm.
From the moment of release, the engine was installed on Largus with van and station wagon bodies. Later found application on other Lada models (Priora, Grant, Vesta.).
VAZ-11189 is characterized by high traction on the “bottoms” and “agility” at high speeds, similar to 16-valve internal combustion engines. Car owners are pleased with the efficiency of the motor.
For example, fuel consumption for Lada Largus (station wagon, manual transmission) on the highway is 5,3 l / 100 km. In addition, another pleasant moment is the official permission of the manufacturer to use AI-92 gasoline for the engine. But, we must pay tribute to the fact that it is impossible to fully disclose the technical and operational capabilities of the engine on this fuel.
Designed for Lada Largus VAZ-11189 had differences from its predecessor in attachments. So, the generator, power steering pump and air conditioning compressor were replaced with more reliable and modern ones, the CPG was redesigned.
The engine received a more efficient catalyst built into the exhaust manifold. A feature of the internal combustion engine is the location of the pump, which receives rotation through the timing belt.
In the manufacture of the engine, new technologies were applied. For example, the connecting rod head is made by tearing. This completely eliminates the appearance of gaps at the junction of the cover with the connecting rod body.
The channels in the cooling system of the cylinder block and its head have been changed. As a result, the process of heat removal became more intense.
Anti-friction graphite sputtering is applied to the piston skirts, which eliminates scuffing in the cylinder and piston when starting a cold engine.
The intake system received significant changes. A new resonator-noise absorber and a new generation throttle pipe have been installed.
It was possible to increase the efficiency of the motor through the use of a lightweight piston group from Federal Mogul, the use of many imported parts and assemblies, the introduction of innovative technologies (electronic throttle control - PPT E-Gas).
A set of engineering solutions ensured good performance, reduced the level of noise and vibration.
The above graph clearly shows that the VAZ-11189 is almost as good as the 16-valve VAZ-21129 in terms of power and torque. Against the background of low fuel consumption, these figures are more than satisfactory.
VAZ-11189 turned out to be quite acceptable for operation. Most car owners recognized it as a very successful unit.

Reliability, weaknesses, maintainability
Reliability
The VAZ-11189 engine is considered a reliable power unit. Numerous reviews on various forums confirm what has been said. For example, Alexey from Barnaul writes: “… I bought Largus with 8 valve 11189. The engine is as simple as an axe. There are no problems with him. Accelerates and drives as it should. I change my oil every 9 miles. There is no expense. Lew shell 5 to 40 ultra ...". Dmitry from Ufa declares: "...There are 2 Largus in our company. One with a 16-valve, the other with an 8-valve engine. Shesnar eats a little butter, 11189 does not eat at all. The run is almost the same - 100 and 120 thousand km, respectively. Conclusion - take the 8-valve Largus ...».
The general trend of reviews is that car owners are satisfied with the engine, the engine does not cause problems.
The reliability of the VAZ-11189 is clearly indicated by the fact that the resource declared by the manufacturer is exceeded. With timely maintenance, the motor is able to work up to 400-450 thousand km without major repairs. (Such figures are confirmed by "hardened" taxi drivers).
And one more touch. The AvtoVAZ auto concern has abandoned imported Renault K4M and K7M engines in favor of the VAZ-11189. The conclusion is simple - if 11189 were not reliable, French engines would have been on Lada Largus.
Weak spots
Despite the high reliability of the VAZ-11189, it has several weaknesses. The most significant are the following.
Low quality mass air flow sensor. Due to his fault, the engine sometimes stalls on the go.
An unreliable thermostat leads to overheating of the motor.
Water pump. It is not uncommon for it to jam. In this case, a broken timing belt is inevitable.
Floating idle. Mostly occur when various sensors fail. First of all - in the throttle control system (E-Gas).
Engine tripping. The cause of the malfunction lies in the malfunction of the ignition system or burnout of the valves.
Unauthorized knocks in the engine compartment. In most cases, they are caused by misadjusted valves. Timely adjustment of thermal gaps eliminates the appearance of this weak point of the internal combustion engine.
In the event of any malfunction, engine diagnostics at a specialized service station is mandatory.
A broken timing belt causes the valves to bend. Despite the long resource of the belt (180-200 thousand km), it will have to be replaced after 40-50 thousand km due to unreliable bearing units of the pump and tension roller.
Other malfunctions are not critical, they occur rarely.
Maintainability
VAZ-11189 is a structurally simple unit with high maintainability. Many car owners note easy accessibility to internal combustion engines. Often, the motor is repaired in garage conditions with their own hands, since troubleshooting does not cause difficulties.
Spare parts for restoration are relatively cheap, they are sold in specialized stores in any assortment.
The only thing you should pay attention to when choosing is not to buy a frank fake. Many of ours, and especially Chinese manufacturers, literally flooded the market with counterfeit products.
Engine restoration is carried out only using original spare parts. It is not recommended to use analogues, as the quality of the repair will be low.
Before starting restoration work, the possibility of acquiring a contract engine should be considered. Sometimes this option is low-budget. The price of such motors depends on their year of manufacture and configuration. Starts from 35 thousand rubles.
The VAZ-11189 engine is unpretentious, reliable and economical with timely and high-quality service. It is in high demand among motorists due to its simple device and good technical and operational characteristics.
