Does the Toyota Echo 1999 have a timing belt and if so when does it have to be changed?

The 1999 Toyota Echo is equipped with a timing chain rather than a timing belt. Timing chains generally do not require regular replacement like timing belts do, but it's important to maintain proper engine care to ensure longevity. However, if you hear unusual noises or experience performance issues, it's advisable to have the timing chain inspected by a professional.
