try to look under the plastic cover near the air manifold, you don’t have to remove the cover, if I’m not mistaken it’s there

That's right, it's at the connection between the cylinder head and the cylinder block. You need to look under the cover with a backlight. You just probably won’t see it.

Thanks everyone, I went to get a flashlight

Where is the engine number located on Toyota Highlander vehicles?

A car like the Japanese Toyota Highlander SUV is always a conscious choice of the car owner. Looking at the person behind the wheel of the mentioned crossover, we can safely say that the driver did not purchase the first model and brand he came across, but selected the car according to certain criteria. Most likely, inside there is a family man who does not waste time on trifles, approaches his choice judiciously and does not waste time. It is possible that such a crossover owner, before purchasing, if we are talking about purchasing a Toyota Highlander on the secondary market, looked not only under the hood, but also checked the engine number, but many do not know where it is located.

Malfunctions and repairs of the 1NZ-FE/FXE engine

The small-volume NZ series of engines appeared in 1999 and was intended for small-class cars; the NZ family included the 1.5 liter 1NZ and 1.3 liter. . In terms of their parameters, NZ engines are similar to larger ones: an aluminum cylinder block that cannot be repaired, a VVTi system on the intake camshaft, a thin single-row chain with an 8mm pitch, etc. Since 2004, hydraulic compensators began to be installed on 1NZ engines; on all previous engines, if necessary, valve clearances need to be adjusted once every 20 thousand km; adjustment is carried out by selecting a pusher.

Toyota 1NZ engine modifications

1. 1NZ-FE – base motor. Compression ratio 10.5, power 109 hp. The engine has been produced from 2000 to the present day. 2. 1NZ-FXE - version for hybrid vehicles, operates according to the Atkinson cycle with delayed closing of the intake valve. Compression ratio increased to 13, power 76 hp. The updated version has a compression ratio increased to 13.4 and a power of 74 hp. In production since 1997.

Malfunctions, 1NZ problems and their causes

1. High oil consumption. Unlike the ZZ series, on NZ engines oil consumption begins mainly after a significant mileage (more than 150 thousand km). In the event of such events, you need to either decarbonize or prepare to replace the oil scraper rings and caps.

2. Knocking and noise from the 1NZ engine. The problem is similar to the 1ZZ motor, namely chain stretching. The malfunction is extremely relevant for engines with serious mileage (150-200 thousand km), and can be solved by replacing the timing chain. Pay attention to the tensioner and chain guide.3. Floating speed XX. The problem is eliminated by cleaning the throttle valve unit (TVB) and the idle air sensor/valve (IAS). 4. Engine whistle. As with many other cars, the 1NZ whistle is caused by a cracked alternator belt. Pay attention to it.5. Vibration of the 1NZ motor. The scheme is standard: look at the engine mounts (front), clean the injectors, change the fuel filter and everything will be fine.

In addition to the above, the oil pressure sensor often dies, the rear crankshaft oil seal 1NZ tends to leak, the cylinder block is unrepairable and after a run of 200 thousand km, most likely, you will have to change the engine to a contract one. To avoid problems and to extend the life of the engine, only high-quality engine oil recommended by the manufacturer should be poured. In general, nothing special, a typical representative of a modern engine, it’s up to you to decide whether to take it or not.

Generations of the Toyota Highlander SUV

The Japanese SUV Toyota Highlander has a twenty-year history and already has 4 generations. The latest version appeared in the fall of 2021 and completely changed the idea of ​​this crossover. But before you find out what the fourth series Toyota Highlander is, you should understand its predecessors, which were also different, and in other matters even surpassed their competitors.

Toyota Highlander first generation

The world first saw this SUV in 2000. It was shown at a car show in America. After the start of sales, top managers of Toyota Motor Corporation realized that the model was successful and very popular. The SUV was of interest to car enthusiasts around the world, and with the advent of this model, sales of the Toyota automobile concern rapidly climbed.

The car was built on the platform of the no less legendary Toyota Camry sedan. The premium version of Toyota, the Lexus RX SUV, also had the same base. The Toyota SUV was equipped with three types of engines:

The crossover was distinguished by both high capacity and increased cross-country ability. The first was achieved by interior ergonomics, the second by increased ground clearance. Already 20 years ago, the car had many electronic sensors that made it possible to control the parameters of the crossover. This model was sold for 8 years.

Toyota Highlander second generation

In 2008, the world was expecting a new product from Toyota. The Highlander has been transformed, leaving only the body shape familiar. The model was shown again in America, but this time at a car show not in New York, but in Chicago. The main feature was the appearance of a hybrid power unit. All power units of different SUV configurations were gasoline and were paired with an automatic gearbox. However, the second generation inherited this trend from its predecessor in the family.

There were three engines to choose from: 2.7, 3.5 and 3.3 liters. The latter was precisely the hybrid version. At the same time, cars began to be produced not only with front-wheel drive, but also with all four driven wheels.

Design Features

The NZ series turned out to be long-lasting:

• 2000 – 2005 – 105 l. s., 138 Nm, assigned index NZE124;
• 2005 – 2007 – 109 liters. s., 141 Nm, NCP90 index;
• 2007 – 2013 – 110 l. s., 140 Nm, index NZT260;
• 2013 – … – 109 liters. s., 136 Nm, index NZT.

The 1NZ FE naturally aspirated in-line petrol engine includes design features of the ZZ/AZ family and fresh developments from Toyota designers:

• cast iron liners are poured directly into the aluminum block, so overhaul of the cylinders is impossible;
• the cast crankcase serves as an oil pan and ensures block rigidity;
• the axis of the forged steel crankshaft is offset relative to the cylinders by 12 mm;
• lightweight piston skirt with polymer coating, press-fit pins;
• a feature of the intake camshaft is the presence of a VVTi clutch for adjusting valve timing;
• the cylinder head is equipped with standard mounting holes for injectors and valve seats;
• the oil pump is located in the crankcase and has a separate drive from the crankshaft;
• heated throttle valve, “cold” thermostat 84 degrees, mechanical type;
• the pump is driven by a common belt, like all other attachments;
• Double-shaft timing belt, DOHC 16V type, driven by a single-row chain on the exhaust camshaft;
• the manifolds have changed location - inlet at the front, exhaust at the rear, so do-it-yourself boosting was made easier by the designers from the very beginning;
• there is no return line in the fuel system, fine-dispersion multipoint injectors;
• mechanical throttle valve, DIS-4 ignition with separate coils for each spark plug.

The performance of hydraulic compensators and the VVTi clutch depends on the quality of the oil. The manual contains a detailed description of the maintenance and repair operations of the power drive.

Power increase 2nz fe

An increase in power worries most drivers of passenger cars who do not have a large engine capacity.

Increasing the power of the 2nx fe motor is possible by using a centrifugal compressor. The convenience of using this device is that its use does not require registration with the traffic police. The centrifugal compressor is designed as an attachment. Currently, there are many modifications of such devices. Centrifugal compressors can significantly increase the power characteristics of a power unit. Such charger kits can be equipped with a disconnectable clutch, or they can be fully integrated into the operation of the power unit.

This method is not a full boost, however, it allows you to achieve a power of 145 hp. It is very important that this method does not reduce the service life of the engine and does not reduce its strength and reliability.

The use of other methods of boosting the power unit is undesirable. Since the design of the 1.3 liter internal combustion engine has mechanical features, modifications of which can lead to increased wear of the ShPG and the entire engine.

Considering the lightweight design of the motor, its restoration after unsuccessful modification may not be practical. And then, instead of increasing power, you will have to purchase a new engine.

Advantages and disadvantages

Initially, Toyota management included a disposable cylinder block in the power drive, the overhaul of which is impossible. The piston pins cause trouble because they are pressed rather than floating. When a chain breaks or jumps several links after stretching, pistons without counterbore bend the valves when they encounter them.

The advantages of the 1NZ-FE motor are:

• high service life from 300,000 km;
• independent chip tuning to increase power;
• lack of adjustment of valve thermal clearances after 2004.

The power drive uses budget AI-92 fuel economically and is not difficult to maintain and repair.

Brief history of the 2NZ FE engine

The engine in question was the latest development of the NZ family of power units. The trend toward fuel-efficient engines emerged in the late 90s, when gasoline prices rose sharply. Small-displacement, economical engines turned out to be just the thing. Serial production of the 2NZ FE began in early 1999, and although modifications of the nz series of internal combustion engines are no longer being designed, the engine in question is being successfully produced today.

Yamaha's development is now somewhat outdated, but it has its advantages and disadvantages. And the efficiency of this engine is impeccable and undeniable.

List of car models in which it was installed

The naturally aspirated in-line four-cylinder engine 1NZ FE, operating on the classic Otto cycle, was installed on Toyota modifications:

• Corolla Fielder/Axio – station wagon for Russia and 11th generation sedan;
• Ractis – subcompact van with a glass roof;
• Succeed – right-hand drive minivan with all-wheel/front-wheel drive;
• Probox – family minivan;
• Will – a youth car with an original design;
• Sienta – minivan with sliding doors;
• Allion – a sedan with a sporty exterior;
• Premio – a sedan for the older generation;
• Fun Cargo – a compact van with an original exterior;
• Auris – family hatchback, new generation of Corolla;
• Platz – classic sedan;
• Porte – subcompact van with doors of different types of opening;
• Raum – subcompact van with automatic transmission;
• Vios – sedan;
• bB – subcompact van in English style;
• Yaris/Echo is a classic sedan.

Additionally, these engines were installed in the Scion xB and xA/ist, and the initial version was used exclusively in the Toyota Prius.

Choosing antifreeze for Corolla 150

The cooling system of the first Toyota Corolla 150 was filled with proprietary Long Life Coolant (LLC) antifreeze. Its article number is 0888980015, and the cost is 600-900 rubles. The coolant is red in color and is sold in concentrated form. It should be diluted with deionized water in a ratio of 50:50 or 40:60.

LLC for cars of early years of production

The use of distilled water to dilute the concentrate is prohibited. Many car owners note that with this mixing, sediment precipitates and flakes form. All this can lead to clogging of the cooling system circuit and cause the engine to overheat. For dilution, it is recommended to use Ravenol destilliertes Wasser with article number 4014835300514.

Most Toyota Corolla 150 vehicles use pink Super Long Life Coolant (SLLC) part number 0888980140. It is sold ready to fill. At the same time, official dealers recommend converting cars from LLC to SLLC, having first flushed the cooling circuit. The cost of pink liquid ranges from 800 to 3000 rubles.

Original antifreeze

Despite the fact that the manufacturer prohibits diluting SLLC antifreeze with water, many car owners claim that the coolant should still be diluted with water in a 50:50 ratio before filling. In this case, it is necessary to use exclusively deionized water, for example, Ravenol destilliertes Wasser.

It is prohibited to add distilled water or other antifreeze to Toyota Super Long Life Coolant. In most cases, this leads to the appearance of sediment and flakes, which significantly impair heat dissipation. However, do not mix original red and pink coolants. They are completely incompatible and undergo a violent chemical reaction.

At the same time, the automaker allows the use of antifreeze from third-party companies. Before filling them, the system must be thoroughly flushed. The best options for the Corolla 150 are shown in the table below.

Table - Antifreeze for Corolla 150 from third-party manufacturers

If, after pouring in fresh antifreeze, its color quickly changes to brown, this means that it does not contain the required amount of corrosion inhibitors. With a high degree of probability, this fluid is counterfeit, so it should be replaced as soon as possible.

Engine tuning options

It is theoretically possible to boost the 1NZ FE engine in seven stages:

• exhaust modernization - forward flow, “spider” and ECU correction to produce 145 hp. With. maximum;
• modification of the fuel system - the use of high-performance injectors and Apexi Power FC “brains” to provide 150 hp. With.;
• supercharging - turbine plus intercooling, installation of a high-performance brake system, power increases to 180 - 200 hp. With.;
• supercharger - usually Supercharger

Thus, the 1NZ FE engine is distinguished by an aluminum block and a timing chain drive according to the DOHC 16V scheme. It is used in almost the entire model range of the Toyota manufacturer, which came off the assembly line from 1997 to 2005, and in some modern cars.

If you have any questions, leave them in the comments below the article. We or our visitors will be happy to answer them

Engines 1NZ FE, 1NZ-FET have increased durability; the only requirement for owners of cars with these engine models is proper maintenance. Thanks to the high quality of workmanship, successful design and excellent technical characteristics, the 1nz fe engine continues to be installed on new models of Japanese cars.

What kind of oil

Sometimes it happens that the recommended oil cannot be filled for some reason, but the original one has not lived up to the trust or is not suitable for a number of reasons, and the question arises - what kind of oil should be poured into the engine, gearbox or power steering of Toyota cars?!

Modern engines and transmissions are especially sensitive to the type of lubricants used. Using the wrong type or class of oil can lead to unusual engine noise and unstable operation of the engine or gearbox.

Mandatory Maintenance

Automakers claim that if the scheduled service periods are observed, the Toyota 1nz fe engine is capable of covering a mileage of at least 500 thousand kilometers. After long-term operation, the engine is not subject to disassembly, repair, or restoration measures. Instead of expensive capital, you will simply have to replace it with a new unit.

The main work performed during maintenance of this engine:

1. Changing the engine oil, in – after 10,000 km.
2. Adjustment of valve clearances - 20 t. km.
3. Changing the timing belt - 150,000 km.
4. Coolant in the system - every 1.5 years.
5. Visual inspection of the technical condition of the air filter - 20 thousand km. If malfunctions occur, the engine must be replaced with a new one.

• Oil “Motul” 5w30;
• Toyota 5W40;
• Castrol 5W40;
• Mannol 5w30.

The total service life of the 1nz fe engine is directly dependent on the frequency and quality of vehicle maintenance work.

Decryption nuances

In addition, according to experts, there are certain differences in how to decipher the VIN number on these cars produced before the mid-90s and after. Now let’s learn more about what information the Corolla identification code may contain and why it is unique.

Decoding VIN TOYOTA for the European market

The symbol from 1 to 3 of the VIN number shows the world index of the automaker.
Next, I will give the designations of all the regions where the Toyota Corolla car was produced and is being produced: Position 4 to 5 – specifies the type of car body (manufactured before 2002):

The 4th symbol for cars produced before 2002 indicates the body type and wheel arrangement:

The 5th character of the VIN number on a Corolla newer than 2002 specifies the engine:

The 6th position indicates the engine or its series (vehicles manufactured before 2002):

The 7th position of the VIN (If your Corolla was produced before 2002) should contain the letter E or T.

The 7th character indicates the presence of passive safety systems (If your Corolla was produced after 2002):

In the 8th position of a car older than 2002 there should be either the Latin letter E (Auris or Corolla) or R (Corolla Verso).

Position 9 of the VIN code is a check digit.

In the 10th position, if a car before 2002 there is a reserve symbol (usually 0), if after, then the model year:

The 11th character specifies the plant where the car was assembled (only for cars from 2002):

The serial number on vehicles manufactured before 2002 is encrypted in numbers from 11 to 17, after which from 12 to 17.

Decoding the Toyota VIN code for the North American market

We have already discussed positions 1 to 3 above (see VIN decoding for the European market).
In the 4th place in the VIN code for cars produced from 1983 to 1995, the engine is indicated: The 4th character of the number can indicate the body type and wheel arrangement of a car produced after 1996:

In the 5th place in the VIN code, provided that the car was manufactured before 1996, there should be the letter E, indicating that this is a Corolla / FX.

The 5th character in the number is the engine (since 1996):

In 6th place in the VIN of a Corolla produced from 1983 to 1990 there were characters 8 or 9, and from 1990 to 1995 0 or 9.

The 6th character speaks of the series (after 1996): 1 – 10, 111; 2 – 20, 110; 3 – 30, 130; 4 – 40, 140.

The 7th character shows the series and classification (for cars 1983–1995): 1983–1990:

Position 7 informs about the presence of passive safety systems (since 1996) similar to cars for Europe (see above).

The 8th number can tell you about the type of body and safety systems (1983 -1990):

The 8th position of the number will inform you about the body type (from 1990 to 1995):

The Latin letter E in the 8th position of a car since 1996 means that it is a Corolla.

The 9th position is the check digit.

10th character model year code (see information above)

The 11th position of the VIN shows the plant where the car was assembled:

From 12 to 17, as always, the serial number.
