The engine was installed on:
- Opel Insignia A (G09) in 2008 – 2013.

Disadvantages of the A20NHT engine
- In the early years of production, owners often encountered sudden traction failures;
- The engine is constantly leaking oil, and it has an extremely large number of weak points;
- The timing chain runs very differently, many had to change it even at low mileage;
- A small resource here has an electronic throttle, as well as high pressure fuel pump;
- When using bad fuel, you can get to replace the piston up to 50,000 km.
This engine is used in some Saab 9-5 and 9-3 models as well as Vauxhall models.
The A20NHT is a solid engine I have insignia 2009 with this engine. It is now on 173,000km and all is fine
