Timing Belt Replacement
Calculate when your timing belt or chain needs replacement and estimate the cost based on engine type and service complexity.
Formula
Timing Belt Interval: ~90,000 miles; Timing Chain Interval: ~200,000 miles; Total Cost = Labor (by engine complexity) + Parts + Water Pump (optional)
Frequently Asked Questions
How often should a timing belt be replaced?
Most timing belts should be replaced every 60,000 to 100,000 miles or 7 to 10 years, whichever comes first. Check your owner manual for the exact interval.
What happens if a timing belt breaks?
On an interference engine, a broken timing belt causes pistons to strike valves, resulting in thousands of dollars in engine damage. On non-interference engines, the engine simply stops running.
Should I replace the water pump with the timing belt?
Yes. The water pump is accessed during timing belt replacement, so replacing it at the same time saves significant labor cost compared to doing it separately later.
