Why does my Mazda Timing Chain or Belt need to be Replaced?

Mazda Timing Chain or Timing Belt Wear

Some Mazda engines use timing chains that can stretch if oil changes are neglected, while others use timing belts that require replacement at set mileage intervals when the belt reaches the end of its service life.

What needs to be repaired or replaced?

We inspect for timing noise, check for stored codes, and follow Mazda’s service intervals for timing-chain-related service or the recommend timing belt replacement. Timing belts have a specified service life and must be replaced when their service life ends. Regular oil changes with the correct viscosity help reduce timing chain wear and extend engine life.
