As of 2015, replacing a timing chain can cost $300 to $1,000. The overall cost depends on the year, make and model of the vehicle and whether the repair is performed by a dealership or an independent repair shop.
Timing chains alone generally cost $50 to $250, but they can cost more for some vehicle models. Some are offered as kits, which can cost $20 to $1,000. Mechanics charge approximately $75 to $120 per hour for labor, and the typical timing chain replacement takes about three to five hours to complete, bringing total replacements costs to $225 to $600. If the timing chain breaks, replacements costs may be $700 or higher.
