The 2005 Mazda 6 is equipped with a timing chain rather than a timing belt. Timing chains are generally more durable and do not require regular replacement like timing belts do. This design helps reduce maintenance costs over the vehicle's lifespan. However, it's still important to follow the manufacturer's maintenance guidelines for overall engine health.

To set the timing on a 2005 Mazda 6, you'll need to ensure the engine is at top dead center (TDC) for the number one cylinder. Align the timing marks on the crankshaft and camshaft pulleys according to the specifications in the service manual. Once aligned, you can install the timing belt or chain, ensuring proper tension. Finally, double-check the alignment before reassembling any components to ensure accurate timing.
Both the 4 cylinder and V6 have a chain.
