Nissan cd20t engine
Content
The Nissan cd20t engine is distinguished by its reliability and long service life. When used in the recommended mode and periodic maintenance does not require frequent repairs.
Despite the years of production, the engine allows you to comfortably travel by car in the city and on the highways.
Engine description
The cd20t motor was developed by Nissan a relatively long time ago. It is a representative of a whole series of diesel engines. It also includes:
- CD17;
- CD20;
- CD20ET;
- CD20E.
The advantage of this engine is its unpretentiousness to fuel. What makes the use of the motor in Russia as comfortable as possible. The unit works well on fuel from refueling and sold "for bottling". The engine was installed in different years on various models of Nissan cars - from 1993 to 2002. Thanks to the characteristics of cars equipped with such a motor, they are still relevant on the road.
Technical specifications
An important advantage is the relatively simple device. This allows you to do your own repairs. Special attention should be paid to checking the timing. If the belt breaks, a major overhaul of the motor will be required. Acquiring parts for cd20t is, if possible, original, their cost is relatively low.

| Compression system present | 22.02.2018 |
| Piston stroke, mm | 88 |
To register a car and some other actions, an engine number is required. Finding it on Nissan cd20t is not so easy. The engine number is located, when viewed from the passenger side vertically, on the right side between the intake and exhaust manifolds. And also the number is located on the plate. If you are located on the side of the hood, you will need to look straight ahead (the easiest way is to figure it out from the photo).
An important issue is the approximate resource of the motor. The mileage after which the replacement of its main working mechanisms is carried out varies depending on the type of fuel.
It is worth noting that the resource of engines running on diesel fuel is at least 2 times longer than gasoline engines (this also applies to cd20t). Some cars produced in 1992 have a mileage of 370 thousand km. During operation, only the replacement of candles, timing components was carried out.
Motor reliability
Reviews of the Nissan cd20t engine are generally positive. But many service workers speak negatively about the motor.
Most often, the cause of breakdowns, in particular the need to replace the cylinder head gasket and connecting rod bushing, is the untimely replacement of consumables, improper operation.
Often complaints are caused by high-pressure fuel pump - a high-pressure fuel pump.
The most frequent repairs required within 5 years on a motor with a range of 100 to 270 thousand km:
- pump adjustment (oil, fuel);
- nozzle cleaning (this is required in some regions, especially often in regions with low fuel quality);
- replacement of belts, rollers (carried out depending on the mileage).
Maintenance of a car with a cd20t engine must be performed at the following mileage intervals (thousand km):
If the engine mileage is more than 300 thousand km, then the following repairs often become necessary:
- replacement of cylinder head gaskets;
- grinding of the heads themselves is required (similar problems arise during prolonged movement at high speed);
- replacement of hydraulic lifters;
- adjustment and installation of a new turbine.
The constant elevated temperature of the engine is the weak point of the Nissan cd20t. It is necessary to use high-quality antifreeze. This will increase the heat dissipation rate. Often there are problems with the interior heating system, usually the stove damper simply does not work.
Maintainability
This motor is distinguished by maintainability. To perform a major overhaul, other maintenance work requires a minimum number of tools and experience. The device of the motor is as simple as possible. It is only important to take into account the tightening torques when assembling and disassembling. When replacing rollers, belts, installation is required in accordance with the marks.
Most often, gasket replacement is required due to overheating of the motor. If the car is purchased with hands, you should carefully check the cooling system. It concerns the state of the radiator. It is necessary to control the operation of the unit in different operating modes. It is important to note that if the temperature arrow “floats”, then the motor was previously overheated.
In this case, it is better to refuse to purchase it. The problem can be increased oil consumption with high mileage, sometimes it is 6-7 liters for every 10 thousand km. In this case, the engine should be overhauled. Components such as the starter and alternator are relatively easy to replace. Their location allows you to access the details without much difficulty.
What kind of oil to pour
The choice of oil directly affects the life of the engine. Moreover, the quality affects such parameters as engine consumption and power. Lubricants 5W-30 are recommended. It is worth buying 5 liters at once. The optimal solution is to replace every 7 thousand km. Since a diesel engine of this type quickly changes the characteristics of the lubricant. Moreover, the manufacturer recommends a replacement every 10 thousand km.
Synthetic oil SAE 5W-30 has proven itself to be excellent. It is important to remember that only specially made for diesel engines should be used in cd20t. Such oils are used in the engines of the cars of Example, Serena. The motor is sensitive to the quality of the lubricant, therefore it is necessary to check the condition visually every 2-3 thousand km.
List of cars on which this engine was installed
This engine has not been installed on modern cars for a long time. However, in the nineties and zero, it was widely used on most models. The reason for this was its unpretentiousness, large resource and simplicity of design. From 1993 to 1995, the installation was carried out on the Nissan Avenir, in the first generation of these machines, in the back of the W10.
After from 1995 to 1998, cd20t was used in the Nissan Avenir Salut station wagon, but again only on the first generation of such cars. The motor was most widely represented in the Nissan Primera series:
- 1999-2002 - restyling, station wagon, generation 2;
- 1999-2002 - reystaling, sedan, 2nd generation, P11 body.
In addition to the above models, the engine was also installed in the Nissan Primera hatchback. Largo vnw30 is a small van used to transport groups of people. Equipped from the moment of release of the first generation and until 1995
The cd20t engine has proven itself well on various models of Nissan cars. But its operation and repair have their own characteristics. It is important to take them into account.
