What It Is

The timing belt keeps your engine's valves and pistons moving in perfect sync. If it breaks, on most engines the pistons crash into open valves and destroy the engine.

Why It Matters

A snapped timing belt on an interference engine means a new engine, often $4,000 to $8,000. Replacing the belt on schedule is one of the cheapest forms of insurance.
