The first generation of the Frontera SUV and the well-liked Sintra minivan were equipped with the 2.2-liter Opel X22XE engine, which was assembled at various factories of the company between 1995 and 1999. The popular Omega model was equipped with this power unit in the EURO 3 version of the Y22XE.

The X20SE, X20XEV, X22SE, X25XE, and X30XE engines are also part of the X20 series.
The engine was mounted on:
- Opel Frontera A (U92) in 1995 – 1998;
- Opel Sintra A (APV) in 1996 – 1999.

Disadvantages of the X22XE engine
Contamination of the idle speed controller, crankcase ventilation, or EGR is linked to traction dips and floating engine speeds;
The exhaust manifold frequently cracks;
The timing belt has numerous issues; when it jumps, the phases go off course; when it breaks, the valves bend; all types of sensors frequently malfunction, but the camshaft and crankshaft position sensors are particularly problematic; hydraulic lifters can knock to 100,000 kilometers when using low-quality lubricant.
