General information about gasoline engines (Opel Frontera A)

The two-door version of the car, called Frontera Sport, has a shortened base and a 2.0-liter engine with a capacity of 115 hp (85 kW). The four-door version of the Frontera has a gasoline engine with a capacity of 125 hp (92 kW). These engines were installed on the car in 1992, 1993 and 1994. In 1995. (since mid-year) the extended wheelbase vehicle is equipped with a 16-valve engine (16V), designated "ECOTEC", which was already used by that time in other Opel vehicles. The "X22 XE" engine has a displacement of 2.2 liters and a power of 136 hp (100 kW). A distinctive feature of this engine is its high torque already at 2600 rpm. The engine has 4 valves per cylinder and direct ignition, a Motronic M1.5.4 injection control system, engine and detonation control, and an exhaust air mixing system. The engine also has an oil radiator and an intake air resonator.

Since mid-1995, a 2.0 liter engine has been installed on cars. The engine is designated "X20 SE". It is a further development of the "C20 NE" engine with an overhead camshaft. This engine is equipped with a Bosch-Motronic M1.5.4 injection control system. The ignition system is so-called direct, i.e. it does not have a distributor and is controlled by an ignition module. The engine uses knock control and has an exhaust gas recirculation system (EGR system). The system is electronically controlled and directs up to 15% of the exhaust gases to the combustion chamber intake. This engine has an oil cooler. The Campo and Brava models were released at the same time.



Since 1997, both of these models have undergone design changes to reduce engine noise levels. For this purpose, a bearing bridge was installed in the cylinder block and a so-called supporting oil pan was used. The 2.2L engine has a redesigned combustion chamber in the cylinder head. This engine has had its air mixing system removed. The control characteristic of the injection control unit has been retained. A manual five-speed gearbox with a two-speed transfer case is installed to reduce the number of revolutions of the rear wheels when driving on rough terrain. The front axle is engaged by a short control lever if driving conditions require it.

The design features of individual models are explained during the description.

Attention! The car has a security alarm device that is triggered when the battery is disconnected. It is necessary to disable the security alarm when performing any work related to disconnecting the battery.

Due to the different engine designs, namely, single overhead camshaft (OHC) engine and double overhead camshaft (DOHC) engine, engine removal and installation work is described separately depending on the design, which makes it easier to understand.

For both engine designs, attention should be paid to the routing of cables, pipes, etc. Therefore, it is recommended to mark the disconnected plugs and cables accordingly if their subsequent connection may be ambiguous. Adhesive tape is convenient for this purpose. The tape is glued to the end of the cable and a digital or letter marking is written on it with a ballpoint pen. When connecting later, you only need to connect the cable in accordance with its marking.



Radio receiver with encoding. When performing the work described in this section related to disconnecting the battery, it is necessary to know the radio receiver code in order to later use it to restore the radio receiver to working condition.
