Timing belt cost breakdown
Parts are relatively cheap; labor drives cost because the belt sits deep in the engine. V6 engines cost more than 4-cylinders.
Interference engines and belt failure
On interference engines, a snapped belt lets valves hit pistons — a repair that can exceed the car's value.
Timing belt vs. timing chain
Chains often last the engine's life but can stretch; rattling at startup is a warning sign.
