When should you change the timing belt on a 2004 Toyota tundra?

The timing belt on a 2004 Toyota Tundra should generally be replaced every 90,000 to 100,000 miles, according to Toyota's maintenance schedule. However, it’s essential to check the owner's manual for specific recommendations based on the engine type, as some engines may have different requirements. Additionally, if you notice any signs of wear, such as cracks or fraying, it’s best to replace it sooner. Regular inspections can help ensure the timing belt is in good condition.
