Opel A20NHT engine
Content
Cars manufactured by the Opel automobile concern are popular not only among our compatriots, but also among residents of European countries. Relative budget, good vehicle build quality, functionality and technical equipment are just a few reasons why Opel cars are chosen. Opel Insignia has established itself among the car park offered by the concern.
The car belongs to the "middle" class and replaced the Opel Vectra in 2008. The car was so popular that a few years ago the second generation was introduced.
This vehicle model was equipped with different engine models in different years. Starting from the release of this model and up to 2013, the Opel Insignia was equipped with the A20NHT engine. This is a two-liter unit, which was installed on expensive versions of the car.
The engine managed to prove itself due to a number of technical features and characteristics. At the same time, starting from 2013, the manufacturer decided to install engines of the A20NFT model on manufactured vehicles. They eliminated a number of shortcomings.
The specifications of the A20NHT engine are as follows:
| Engine capacity | 1998 cc cm |
|---|---|
| Maximum power | 220-249 h.p. |
| Maximum torque | 350 (36) / 4000 N*m (kg*m) at rpm |

| 400 (41) / 3600 N*m (kg*m) at rpm | |
| Fuel used for work | AI-95 |
| Fuel consumption | 9-10 l / 100 km |
| engine's type | 4-cylinder in-line |
| CO2 emission | 194 g / km |
| Number of valves per cylinder | 4 |
| Maximum power | 220 (162) / 5300 hp (kW) at rpm |
| 249 (183) / 5300 hp (kW) at rpm | |
| 249 (183) / 5500 hp (kW) at rpm | |
| Compression ratio | 9.5 |
| Supercharger | Turbine |
In order to find out the engine identification number, you need to find a sticker with the relevant information on the engine.
Many who have operated the Insignia model on which this engine is installed have encountered the fact that it had a low fuel pump life. The timing chain is also not perfect. As a result, drivers are faced with overloading the piston group. Due to the fact that the engine of this model is “sensitive” to fuel, certain problems may arise during operation.
At the same time, in a motor with four valves, the timing is driven by a chain, the operational life of which is up to 200 thousand kilometers. To increase the resource, the manufacturer uses hydraulic compensators.
Advantages and disadvantages of internal combustion engines
This engine model allows you to provide good dynamic performance. But at the same time, the power unit consumes not a small amount of fuel. The timing drive is chain. Timing gears are used on the shafts, which cannot be called durable in operation. Their cost is more expensive than similar ones that are installed on a 1,8 engine.
One of the shortcomings of engines produced in the early years was also the destruction of the partitions between the rings on the piston.
Unfortunately, motorists consider this motor "capricious". Traction failures occurred even during the break-in period. As a rule, after performing the usual "reboot", that is, turning off the motor and restarting, this problem disappeared for a certain period of time. However, sooner or later it leads to the need to replace the turbocharger.
Many drivers do not pay attention to this problem. As a result, the engine needs to be overhauled or replaced. A warning light indicating a problem in the motor works late when serious enough repairs are required. By the way, when such a breakdown occurred during the warranty period for a car, dealers stated that the reason was the use of low-quality fuel, as well as the driver’s failure to pay attention to oil control.
Performing engine repairs
The overhaul of the engine of this model includes the following types of work:
- Flushing inside the motor, cleaning and lapping the valves, replacing the pistons with new ones.
- Changing oil, spark plugs, coolant. Flushing the fuel system.
- Flushing and installation of the repair kit on the injectors.
Engine Chip Tuning
Engine chip tuning is supported. Contacting a specialized service station allows you to order the execution of work that will allow:
- Increase engine power and torque.
- To finalize the intake and exhaust system, reinforcement, as well as the modernization of all vehicle units.
- Perform engine tuning.
- Prepare and configure the firmware.
Purchase of a contract engine
In the event that the situation with the operation and repair of the vehicle has been “launched”, then with a high degree of probability the overhaul will be much more than buying a new engine. In general, there are no problems with finding a motor. The price for a new contract engine is about 3500-4000 US dollars.
It is also possible to find a donor car and purchase a motor at a much lower price.
It must be understood that the issue of replacing a car engine is a complex type of work that needs to be entrusted only to professional specialists. The fact is that buying a new or used engine that is fully functional and suitable for further operation is, in general, not the cheapest pleasure. For this reason, if the engine is installed incorrectly, then in the future the operation of the vehicle will be problematic or generally impossible.
For this reason, it is recommended to contact those services that specialize in Opel cars. Previously, service station employees will be able to advise the client, including on the issue of purchasing an engine.
