Prizm's had a timing belt up until 1998 when they then switched to a timing chain.
Its a non interferance engine and they rarely need to be changed
I can't say for sure, but I have a 2001 Prizm and called some mechanics to look into having the belt changed, and they told me I didn't need to because it has a chain. According to the repair manual from 1993 through 1997 the Prizm used a timing belt and was an interference engine. From 1998 until end of production the Prizm used a timing chain. same with its mechanical twin, the Toyota corolla.
