Regardless of what car you drive, an inexpensive domestic one, or a premium foreign car, sooner or later you will encounter an engine malfunction. Power plants of even the most quality cars, for example, Mazda cx7, wear out as a result of constant operation and the influence of high loads. As a consequence: engine power is significantly reduced, and at the same time, the unit requires more fuel and oil. In this case, it is necessary to solve the engine problem as soon as possible - paying attention to the early stage of the malfunction and eliminating the problems in a timely manner, you significantly save on repairs.

The Mazda CX-7 engine is a power unit installed on Japanese crossovers. The motor is marked MPS SUV. There are two options for power units that are installed on this vehicle.
Specifications
Engines, which are equipped with Mazda CX-7, have two options - with reduced power characteristics and increased. The first engine has a gasoline design, as well as a stock of 163 horse power, with a volume of 2.5 liters. Second option power unit equipped with a 2.3 liter engine with a capacity of 238 hp.
Such a power jump is achieved due to the presence of turbocharging.
Consider the main specifications Mazda CX-7 engines:
2.5 liters
2.3 liters
Service
Map Maintenance as follows:
TO-1: Oil change, change oil filter... Carried out after the first 1000-1500 km of run. This stage is also called the break-in stage, since the engine elements are lapped.
TO-2: The second maintenance is carried out after 10,000 km of run. So, the engine oil and filter, as well as the air filter element are changed again. At this stage, the pressure on the engine is also measured and the valves are adjusted.
TO-3: At this stage, which is performed after 20,000 km, a standard oil change procedure is carried out, fuel filter, as well as diagnostics of all motor systems.
TO-4: The fourth maintenance is perhaps the simplest. After 30,000 km, only the oil and the oil filter element change.
TO-5: The fifth TO for the engine, like a second wind. A lot of things are changing this time. So, let's consider which elements will be replaced in the fifth maintenance:
- Change of oil.
- Replacing the oil filter.
- Replacing the air filter.
- Replacing the fuel filter element.
- The timing belt and roller are changing.
- Alternator belt if necessary.
- Water pump.
- Valve cover gasket.
- Other items to be replaced.
- Valve adjustment, in which the gas distribution mechanism is regulated.
Subsequent maintenance is carried out according to the 2-5 maintenance card for the corresponding mileage.
Output
Mazda CX-7 engines are considered one of the most reliable power units of the brand. The motor is not easy to maintain and expensive to repair, and therefore the owners often do not spare money for service maintenance.
Mazda cx 7 belongs to the SUV class and is a mid-size Japanese car with five seats.
More than 10 years have passed since the creation of the Mazda cx 7 car. However, it was officially unveiled in January 2006 at the Los Angeles Auto Show.
ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe me? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline!
The basis for its creation was the concept of this crossover called the MX-Crossport, which was unveiled a little earlier, in 2005. The launch of mass production of the Mazda CX 7 took place in the spring of 2006, at the concern's car plant in Hiroshima. It is worth noting that the crossover has aroused great interest among drivers who like serious equipment.
For reference! Iwao Koizumi, chief designer of Mazda, claims that he invented the exterior of this crossover in a fitness center, which emphasizes the exterior of the car. After all, the design of the CX-7 turned out to be sporty-aggressive both inside and outside!
Four years later, the model was re-styled, the main change of which was the appearance of a front-wheel drive vehicle layout. The Mazda cx 7 was discontinued in 2012, just six years after its launch. The management of the company decided to complete the production of this crossover, which is very popular, due to the release of a newer model.
For reference! The predecessor of the Mazda cx 7 is famous car Mazda Tribute, and its successor became more new crossover Mazda CX-5!
It's no secret that the crossover was designed for absolutely new platform, which was designed specifically for this car.
Despite this, a significant part of the units, assemblies and mechanisms of the Mazda cx 7 are borrowed components of other models from the Mazda company. For example, the front suspension is entirely taken from the Mazda MPV minivan, and the rear, the developers decided to take the suspension from the Mazda 3, which has undergone minor modifications.
The all-wheel drive transmission, which was also equipped with the presented crossover, came from the Mazda 6 MPS. In addition, the 6th generation Mazda presented the owners of the CX-7 with a derated engine with a capacity of 238 hp. The gearbox is a six-speed automatic unit "Active matic", which has a manual shift function.
It should also be noted that the Mazda cx-7 car has a security system, which includes the following elements:
- Six airbags;
- Dynamic Stability Control (DSC);
- Anti-lock braking system (ABS);
- Emergency Brake Booster (EBA);
- Traction Control (TSC).
Specifications Mazda cx 7
Before describing the specifications this car, it is necessary to clarify that there are different modifications of it depending on the region of delivery, each of which has a standard and re-styled version:
- Russia;
- Japan;
- Europe;
Below is a table that shows the technical characteristics of the engines with which the crossover was equipped:

Based on the above table, we can safely say that the Mazda CX-7 engine range does not differ in a wide range of choices. There are only 3 ICE options to choose from - a diesel power unit and two gasoline ones.
The first one is called MZR-CD R2AA, has a working volume of 2.2 liters and is equipped with a turbocharger, which allows it to produce 170 hp, acceleration from 0 to 100 km / h takes 11.3 seconds, and the average fuel consumption is 7, 5 liters. Below is a photo this engine in the engine compartment: 
For reference! On the CX-7 crossovers, which were assembled for the European market, an additional cleaning system was installed exhaust gases(SCR)!
The 2.3-liter L3-VDT gasoline engine inherited the CX-7 from the Mazda 6 MPS. It included a direct fuel injection system, turbocharging and an intercooler. This motor was installed both on cars with mechanical transmission, which made it possible to obtain a power of 260 hp, and with a six-speed automatic transmission gears, as a result of which, the power was reduced to 238 hp.
It should be emphasized that both versions of this power unit do not differ in efficiency, because according to the passport data, the fuel consumption reaches 11 - 11.5 l / 100 km in the combined cycle. However, thanks to the presence of a turbine, the CX-7 crossover has good acceleration dynamics - 8.3 seconds to 100 km / h. Below is the L3-VDT in one of the Japanese catalogs: 
The last of the two gasoline engines, with a displacement of 2.5 liters, was installed on the post-styling versions of the Mazda cx 7. This engine differs in that it does not have a turbine and is considered an atmospheric power unit. Its power is 161 hp, acceleration to 100 km / h takes 10.3 seconds according to passport data, and fuel consumption is in the combined cycle.
The engine is named L5-VE and works in conjunction with a five-speed automatic transmission. It is found in the front-wheel drive CX-7 models, which are intended for the American market. There is also a Russian version of the L5-VE internal combustion engine, which works in conjunction with a manual transmission and allows you to reach 170 hp. 
With which engine to choose the Mazda CX-7
When choosing an engine, first of all, you should consider your own preferences. For example, for one driver, an important parameter is the dynamics of the car, its maximum speed... The turbocharged L3-VDT engine is best suited for these purposes. However, it should be understood that the supercharger not only adds power, but also reduces the life of the engine.
In addition, according to the owners of this power unit, problems with the turbine and oil starvation of the engine very often arise. Fuel consumption is also an important parameter, because turbocharging significantly increases it.
Naturally, for most drivers, the reliability of the engine, its efficiency and resource are more important. For these purposes, the naturally-aspirated L5-VE engine with a displacement of 2.5 liters is best suited.
Unfortunately diesel engine MZR-CD R2AA, which is installed on European variants of CX-7 in our country, is extremely rare. However, if you are lucky enough to find such a copy, then it will be a good alternative to the gasoline aspirated. Diesel motors have greater efficiency and service life, and also have greater traction.
What is the most popular engine among the owners of the Mazda CX-7
In our country, almost all Mazda CX-7 cars are equipped with a gasoline turbocharged L3-VDT engine. And this is not because it is the most attractive option. The thing is that on our secondary market finding any other engine is an extremely difficult task.
This motor gives such a difficult crossover a pleasant acceleration dynamics, however, with reliability, everything is not entirely smooth. So the most frequent problems in the L3-VDT engine are:
- Supercharger (turbine). The owners note that this unit breaks down very often, without showing any signs of future breakdown. However, it should be borne in mind that many owners reduce the operating life of the supercharger with their own hands, making poor-quality maintenance;
- Increased wear on the timing chain. Many owners agree that it can stretch for as little as 50,000 km;
- VVT-i coupling. If the other two malfunctions are difficult to identify or prevent, then everything is much easier with the clutch. The main sign of its failure is a crackle when starting the engine, and immediately before its breakdown, the sound of the engine becomes rough, more like a diesel internal combustion engine.
Recommendation! The gasoline turbo engine is characterized by increased consumption engine oil... For the L3-VDT, the norm is 1 liter per 1,000 km. It is very important to monitor the level of engine oil, because its lack entails increased wear not only of the turbine, but also of all engine systems!
