timing belt
Valve coordination strap
A timing belt is a toothed rubber belt that synchronizes the rotation of an engine's crankshaft and camshaft, ensuring valves open and close at precisely the right moments.
Timing belts require periodic replacement—typically every 60,000 to 100,000 miles—because a snapped belt can cause catastrophic engine damage.
The mechanic said my timing belt was due for replacement.
