Three symptoms of a faulty timing belt include a high-pitched sound, visual damage and a problematic startup. If any of these signs are detected, the timing belt should be replaced immediately to avoid drastic consequences.

A timing belt is a component of an automobile's engine driven by the crankshaft. It operates the camshaft of the vehicle. If the belt breaks while the engine is running, it may cause serious damage to the engine. Most car manufactures recommend that car owners change the timing belt every 40,000 to 60,000 miles. Retail chain parts stores sell timing belts for around $20 to $40.
