On a 1997 Chevrolet Cavalier with a 2.4L engine (likely the DOHC), the cylinder numbering typically follows a sequence starting from the timing belt side of the engine. Therefore,
cylinder #1 is at the front of the engine, on the passenger side (right side when looking at the engine from the front of the car).
However, always double-check your specific engine's markings. The number might be cast directly onto the engine block near the cylinder head. A repair manual for your specific year and model Cavalier would be the definitive source.
