Here's a breakdown:
* 1st Generation IS300 (1999-2005): The 2JZ-GE engine is non-interference. This means that if the timing belt breaks, the valves won't hit the pistons.
* 2nd Generation IS300 (2006-2008): The 2GR-FE engine is interference. This means if the timing belt breaks, the valves will collide with the pistons, causing severe engine damage.
Therefore, it's crucial to know the exact year and model of the IS300 to determine if it has an interference engine.
Always consult the owner's manual or a reputable repair shop for the most accurate information.
