How often do you have to change the timing chain on a 4-cylinder 2.4 liter Toyota?

The timing chain in a Toyota 2.4-liter 4-cylinder engine does not require regular replacement and typically lasts the lifetime of the vehicle, unlike timing belts that need to be replaced periodically. In general, timing chains are more durable and long-lasting compared to timing belts and are designed for extended use without the need for frequent replacements.
