The most well-known models of the era, including the Astra, Corsa, and Kadett, were equipped with the 1.4-liter Opel C14NZ engine, which was manufactured in Germany between 1989 and 1996. The well-known C13N engine on the conveyor was replaced by this power unit before the X14XE took its place.
The C16NZ and C18NZ engines are also part of the C10 line.
The engine was mounted on:
- Opel Astra F (T92) in 1991 – 1996;
- Opel Corsa A (S83) in 1989 – 1993; Corsa B (S93) in 1993 – 1996;
- Opel Kadett E (T85) in 1989 – 1991.

Disadvantages of the C14NZ engine
The spark continuously vanishes in the ignition system, which causes the most issues.
The distributor’s cover should be the first place to look for the cause, followed by the candles and wires;
Keep an eye on the timing belt’s condition; it has a 60,000-kilometer lifespan and bends the valves when it breaks.
Electronic sensors of all kinds, particularly the lambda probe, frequently malfunction;
The idle speed controller, the fuel pump in the tank, and the thermostat all have limited resources.
