How often does a timing chain on a Mazda 3 2013 model need to be changed. At what kms? Thank you in advance 🙏🏻

1 Answer 1


The owner's manual for 2013 Mazda3 specifies two different maintenance schedules:

  • Schedule "A" for normal use
  • Schedule "B" for severe use

Schedule A, normal use, calls for the drive belts every 37,500 mi / 60,000 km. See page 8-5 in the manual.

Schedule B, severe use, calls for the drive belts every 35,000 mi / 56,000 km. See page 8-7 in the manual.

Timing chains are not mentioned. From what I can see in online discussion, 1,2,3,4 most people believe they are supposed to last the life of the car, or until the engine requires a complete rebuild.

Since Mazda does not specify any required replacement of the timing chain, you should be good for at least 150,000 to 200,000 miles (240,000 to 320,000 km).
