Does the 2000 Mazda MPV have a timing belt or chain?

The 2000 Mazda MPV comes with a 2.5 L V6 engine that has a timing chain instead of a belt. MPV's that were manufactured before the year 2000 come with timing belts but this marks the first year that they made the switch. Since You've got a chain the main thing to know is that there isn't really a scheduled replacement time for it like there is a with a belt. Even in a 20+ year old vehicle there is a good chance it is using the original chain if the vehicle has been maintained well. Keeping up with Your regular oil changes should keep the chain lubricated properly and running smooth for many years. -
