Timing Belt Replacement Cost
Timing belt replacement typically costs $300–$900 including parts and labor. It's one of the most important scheduled maintenance items on vehicles that use one — skipping it can result in catastrophic engine damage costing thousands.
Average Cost
- Economy/aftermarket kit: $300–$500
- OEM kit with water pump: $500–$900
- Labor: 3–6 hours depending on engine complexity
- Water pump is almost always replaced at the same time (same labor access)
Does My Car Have a Timing Belt or Chain?
Most modern cars (2010+) use timing chains, which are metal and typically last the life of the engine. Timing belts are rubber and require scheduled replacement. Belts are more common on Honda, Subaru (some engines), Toyota V6, Mitsubishi, and Hyundai/Kia. Check your owner's manual or look up your specific engine — this is critical information.
Replacement Interval
- Most manufacturers recommend replacement every 60,000–100,000 miles
- Time-based replacement also applies — typically every 7–10 years regardless of mileage
- Always follow the earlier of the two (mileage or time)
- High-performance and turbocharged engines may have shorter intervals
What Happens if the Timing Belt Breaks?
On interference engines (most modern cars), a broken timing belt causes the pistons and valves to collide. This bends valves and can crack pistons, resulting in $2,000–$6,000+ in engine repair or requiring a full engine replacement. On non-interference engines, the car simply stops — less damage, but still stranded. Never delay timing belt replacement.
What to Replace at the Same Time
- Water pump (same access, add $50–$150 in parts)
- Idler pulleys and tensioner (same kit, usually included)
- Serpentine belt (often accessible at same time)
- Coolant (drained during water pump replacement)
