Toyota recommends replacing the timing belt at 60,000-mile intervals. The reasoning is this engine uses a hydraulic belt tensioner with a specific amount of throw. The timing belt rarely shows any wear, however, it stretches, as do all timing belts. Using the timing belt over 60,000 miles stretches the limits of the belt. Even though the Toyota’s engine is a freewheeling engine, where it is unlikely that a thrown timing belt will cause any significant damage, for peak functionality, replace the timing belt as per manufacturer’s directions. Replacing the timing belt is a job for an experienced home mechanic with a good understanding of the mechanical aspects of an engine and is not a job for a novice. One mistake can cause catastrophic damage.
